Here you will find an overview of screw compressors, oil-free compressors, piston compressors, high-pressure compressors, marine compressors, and gas compressors for stable and energy-efficient solutions. Dansk Trykluft Industri A/S supplies, installs, and services compressors for industry, production, and workshops.
A screw compressor is today the most widely used type of compressor in industry – and for good reason. It delivers a stable and continuous compressed air and gas supply, compressed air supply, requires limited maintenance and is also both quiet and energy-efficient in operation.
If you have a continuous or regular compressed air requirement, a screw compressor is often the best choice. It is built for many hours of operation and provides a stable compressed air supply, which is well-suited for professional environments.
Typical advantages include:
If your compressed air demand varies throughout the day, a variable speed screw compressor (variable speed drive) can be an ideal choice. Here, the compressor output is continuously adjusted to the current demand, which typically results in lower energy consumption during fluctuating loads.
This is particularly relevant in companies where compressed air is not used constantly in the same amount – for example with changing production, varying staffing or periods with low load pressure.
The right solution depends not only on the size of the compressor, but also on the operating pattern and requirements. When we advise on the selection of a screw compressor, we typically base it on:
The goal is to ensure a solution that works both technically and provides good operating economy.
At Dansk Trykluft Industri, we offer both new and used screw compressors. A used solution can be attractive if you want a professional compressor at a lower investment – without compromising operation and functionality.
Whether you choose new or used, we are happy to advise on model selection, capacity and setup so the solution matches your needs.
An oil-free compressor is a machine that produces compressed air without the use of oil in the compression chamber. This means that the compressed air produced is completely free from oil residue and contaminants, making it ideal for applications where purity is critical, such as in the pharmaceutical industry, food production, and electronics.
We offer a wide range of oil-free compressors suitable for different applications, such as:
A professional piston compressor, also known as a reciprocating air compressor, is a machine used to compress air or gas using a piston engine.
When investing in a piston compressor for industrial or professional use, it is crucial to choose a model that matches your operational requirements and ensures stable, efficient production. Here are the key parameters you should evaluate:
Start by defining the specific application. Will the compressor be used for intermittent tasks, such as operating individual pneumatic tools, or for the continuous supply of production lines? A compressor’s duty cycle indicates how much of the time it can run without being overloaded. For heavy, continuous operation, you should choose a model with a 100% duty cycle.
It is not enough to look at engine power. The compressor's real performance is measured in free air delivery (FAD), which indicates the amount of usable compressed air delivered at a given pressure. Always dimension the compressor so that the FAD is above your maximum consumption, including peak loads, to avoid pressure drops and inefficient operation.
Most industrial applications require a working pressure of 8-10 bar, but certain processes, for example in the food or metal industries, may require higher pressures. Ensure that the compressor has sufficient pressure capacity to handle both current and future needs, and that the air quality matches the requirements of your production – for example, through air quality analysis.
An efficient cooling solution is crucial to avoid overheating, especially under high load. Professional piston compressors are often equipped with forced air cooling or oil cooling, which extends service life and reduces maintenance costs.
Choose a model with robust components, easy access to service points and quality materials that ensure high operational reliability.
A high-pressure compressor is used when standard compressor solutions are not sufficient and there is a need for higher working pressure, high operational reliability, and a stable supply. This may be in production, in a workshop, or as part of a process where compressed air plays a critical role.
The choice of a high-pressure compressor should always be based on the actual operational needs – not just a pressure rating on paper. The most important parameters are:
1) Pressure and operating point
What working pressure must the system deliver – and does it need to be continuous or only required periodically? We help with sizing, so you do not end up with overcapacity or undercapacity.
2) Capacity and consumption (m³/h or l/min)
How much compressed air do you need per hour, and how often does the compressor need to deliver it? A correct match results in lower energy consumption and fewer operational stoppages.
3) Operating time and load profile
Should the compressor run for a few hours per week or across multiple shifts? The load profile has a significant impact on both the technology, cooling, and expected service life.
4) Environment and installation
Location, temperature, ventilation, and noise requirements all play a role – especially when operating in production environments or technical facilities. Here, the right setup can make a significant difference for both performance and maintenance.
A high-pressure compressor is often an investment that must be able to deliver consistently over many years. Therefore, many companies choose high-pressure solutions when the demands for operation and process are high.
In many industrial environments, compressed air is not “just air.” Depending on the application, it may be relevant to consider:
We are happy to advise on the complete solution, ensuring that both the compressor and downstream treatment match the operational requirements and process.
Marine compressors must be able to deliver stable performance in demanding environments with high temperatures, vibrations, and varying loads. Therefore, ALMiG marine compressors have been developed with a focus on robustness, reliability, and longevity.
In maritime installations, compressed air is typically used for two purposes: control air and working/process air. While control air often requires stability and operational reliability for control and automation, working/process air can be more demanding in terms of load and may vary in consumption.
ALMiG marine compressors can be configured to match the specific application – whether the focus is on stable control, high supply reliability, or operation under varying consumption patterns.
ALMiG marine compressors are built as single-stage, oil-injected, and air-cooled screw compressors, making them both efficient and operationally stable in daily use. At the same time, the solution is developed with a compact design, allowing for space-saving installation – for example, close to walls or in corners, where space is often limited onboard.
ALMiG marine compressors cover a relevant performance range for many marine applications. The solution is typically delivered in capacities from 1.50–5.17 m³/min at 8 bar(g), and models can also be supplied for 10 or 12 bar(g) depending on the installation and requirements.
At Dansk Trykluft Industri, we help you size the right solution, ensuring that capacity, pressure, and operating scenario match your specific operation – so you avoid both under- and oversizing.
In maritime environments, equipment is exposed to conditions that place particularly high demands on construction. Salt, humidity, temperature variations, and vibration can affect both components and operational reliability.
With an ALMiG marine compressor, you get a solution that is developed for stable operation under demanding conditions. This contributes to fewer unexpected stoppages and more predictable operation over time.
Marine compressors must be easy to monitor, control, and optimize – especially when operational reliability and energy optimization are in focus. ALMiG is supplied with modern control systems and touch operation, making it easy to work with operating data and settings.
In addition, the solution can be integrated into overall control systems, enabling better monitoring, planned maintenance, and a more data-driven approach to operation.
ALMiG marine compressors are manufactured in Germany and produced in accordance with applicable CE requirements. This is an important factor for many companies and installations, where documentation, quality, and consistent product standards play a role in the selection process.
A gas compressor is used in an increasing number of industries in Denmark. As more cars and electric vehicles are equipped with fuel cells or become gas-powered, there is a growing need for gas compressors.
Gas compressors are available from 1.5 kW to 500 kW and are typically either piston, diaphragm, or screw compressors. Gas compressors are often subject to ATEX regulations, as the gases being compressed may be explosive. If it concerns nitrogen, there is no explosion risk.
Our gas compressors are all CE-marked and often ATEX-approved with full documentation. A gas compressor is used in industries such as natural gas production, biogas production, hospitals, and the chemical industry.
Is it time to invest in a gas compressor, or do you perhaps already have one that needs a service inspection? If you are looking for a company specializing in exactly this, then we at Danish Compressed Air Industry is an an obvious choice.
We supply and service the following: hydrogen compressors, oxygen compressors, CO2 compressors, helium compressors, natural gas compressors, CNG compressors, biogas compressors, methane compressors, and much more.
We are based in Gadstrup, from where we travel to many different types of companies across the country to supply and service compressors, including gas compressors.

A screw compressor compresses air using two counter-rotating screws (rotors). The air is drawn into the compressor, and as the screws rotate, the air volume is gradually reduced. This increases the pressure until the compressed air is delivered into the compressed air system.
This compression method provides a smooth and stable air flow without large pressure fluctuations. This makes screw compressors particularly suitable for operating situations where constant compressed air and high uptime are required.
A screw compressor is often the best choice when you use compressed air regularly or continuously. It provides high operational reliability, lower noise levels and a more stable air flow than many alternative compressor types. Therefore, it is often chosen in companies where compressed air is an important part of operations.
An oil-injected screw compressor uses oil in the compression process, which helps with lubrication, sealing and cooling. It is a very common solution in industry where efficient operation and long service life are desired. An oil-free screw compressor is typically used in environments where particularly high requirements for air purity are needed and where compressed air without oil content is required.
A variable speed screw compressor regulates the motor speed so the compressor adjusts its output to the current compressed air demand. This can provide more energy-efficient operation in companies where air demand varies throughout the day. In practice, it can reduce energy consumption and provide more stable operation without unnecessary “idle running”.
The correct sizing depends, among other things, on capacity (air consumption), operating pressure and operating profile. A compressor that is too small can cause unstable pressure and strain on the system, while a compressor that is too large can lead to unnecessary costs. We are happy to help assess the requirements and choose a solution that fits both operations and finances.
Yes, at DTI A/S, we offer both new and used screw compressors. A used compressor can be an attractive solution if you want a professional compressor for a lower investment. We are happy to advise on the choice of used equipment, so you get a solution that fits your needs and operating pattern.
Low noise levels and fewer vibrations provide a better working environment and can make it easier to place the compressor in or close to the production area. At the same time, lower vibrations often mean less mechanical stress on equipment and components, which can contribute to more stable operation over time.
Yes, we offer service and maintenance of screw compressors and assist with operation, troubleshooting and spare parts. We service customers throughout Denmark and can also advise on optimization or replacement of existing compressed air solutions.
Oil-free compressors operate by using specially designed piston or screw mechanisms that do not require oil for lubrication in the compression process. Instead, they use high-performance materials and advanced cooling systems to minimize wear and ensure efficiency. This results in reliable operation and clean compressed air that meets strict standards.
The choice of an oil-free compressor depends on several factors, including your specific need for air quality, pressure level, flow rate, and budget. It is important to choose a compressor that suits your intended use and can deliver the required capacity. Also consider energy consumption and maintenance requirements.
Oil-free compressors are used across a wide range of industries where high air quality is essential. These include the pharmaceutical industry, dental practices, food and beverage production, microelectronics, biotechnology and laboratory environments. Wherever cleanliness and hygiene are paramount, an oil-free compressor is the ideal choice.
The advantages of choosing an oil-free compressor include high air quality, reduced risk of contamination, lower maintenance costs and increased energy efficiency. These compressors are also more environmentally friendly, as they do not require the use of lubricating oil, which reduces the need for disposal of hazardous waste.
In this type of compressor, a piston rod moves back and forth inside a cylinder to reduce the volume and increase the pressure of the trapped air or gas. Piston compressors are among the oldest and most widely used compressors in industry, and they are available in both single and multi-stage models, depending on the desired pressure levels.
A piston compressor operates in a simple but effective way. When the piston rod moves downward in the cylinder, a vacuum is created that draws air in through an intake valve. When the piston moves upward again, the intake valve closes and the air is compressed as it is forced out through a discharge valve. This creates pressurized air that can be used for various purposes. This cycle repeats continuously during operation, making it possible to deliver a steady flow of compressed air.
Piston compressors are used in many different industries and applications, including:
When comparing reciprocating compressors with screw compressors, there are several differences that can affect the choice. Reciprocating compressors are known for their simplicity, reliability, and cost-effectiveness, making them ideal for smaller and medium-sized tasks. However, they require regular maintenance and can be noisier than screw compressors.
Screw compressors, on the other hand, are more complex but offer higher efficiency, lower noise levels and can often run continuously for longer periods without overheating. They are better suited for larger industrial applications where a constant compressed air supply is required.
High-pressure compressors are used in many industrial setups where pressure, volume, and operating time must be documented and delivered consistently. They are used, among other things, for:
If you have a specialized application, we are happy to advise on the right solution and the best operational reliability in practice.
High-pressure compressors are often used in industry, where compressed air is a critical part of operations. This may include the automotive and transport sector, laboratories and test environments, the pharmaceutical and process industries, as well as energy and manufacturing companies with high demands for uptime and pressure stability.
The right choice depends on several factors: required working pressure, air volume/capacity, operating time and load profile, as well as environmental and installation conditions. At Dansk Trykluft Industri, we help with sizing and selecting the right solution, ensuring the compressor matches your needs in practice – not just on paper.
A standard compressor is typically used for general compressed air tasks in, for example, workshops and production, while a high-pressure compressor is designed for higher pressures and more demanding operating conditions. High-pressure compressors are often chosen when stable pressure, operational reliability, and a robust solution are essential.
The capacity depends on your consumption, the number of consumption points, and whether the compressed air is used continuously or in intervals. A correctly sized solution provides better operation, lower energy consumption, and a reduced risk of pressure drops – therefore, we always recommend basing it on your actual load profile.
Yes, in many B2B environments, air quality is important – especially in process applications, testing, laboratories, and production, where stable operation and clean compressed air can be critical. Filtration, drying, and condensate management should be assessed as part of the overall solution to ensure optimal operation and minimize downtime.
Running time and load profile are of great importance to which solution makes the most sense economically and technically. If the compressor is to run in long operating cycles or multiple shifts, it places higher demands on both sizing, cooling, and robustness – and here, the right solution can provide significantly better stability and lifespan.
When compressed air is a critical part of operations onboard or in offshore installations, there is no room for uncertainty.
The compressors are designed for stable operation – even at ambient temperatures up to 50 °C – and are suitable for a wide range of maritime applications.
In many installations, the compressor is a significant part of the energy consumption. Therefore, the choice of a marine compressor should not only be about performance here and now – but also about operating economy over time.
ALMiG marine compressors are developed with a focus on efficient operation and high uptime. This provides a strong foundation for reducing energy waste, minimizing operational losses, and achieving better overall economy – especially in operating situations where compressed air is a regular part of daily operations.
Control air is typically used for control and automation and requires high stability and operational reliability. Working/process air may have more variable consumption and is often used for functions with higher load. The marine compressor can be sized and configured to match the specific need.
ALMiG marine compressors are single-stage, oil-injected, and air-cooled screw compressors. This provides an efficient and operationally stable solution that is well suited for installations requiring stable performance and high uptime.
