KAESER Screw Compressors with Refrigeration Dryers

Screw compressors with integrated refrigeration dryer – 4.0 to 22 kW, max. 8 to 15 bar

KAESER screw compressors with the model designation “T” combine a screw compressor and a refrigeration dryer in a single housing. Four model series ranging from 4.0 to 22 kW, operating pressures from a maximum of 8 to 15 bar, and a pressure dew point of +3 °C using the refrigerant R-513A (GWP 631)—for dry, condensate-free compressed air straight from the compressor.

Summary List

KAESER Screw Compressors with Refrigeration Dryers – An Overview of All Models

The following overviews show all KAESER Screw compressors with integrated refrigerant dryers, organized by series. The model designation “T” stands for the factory-integrated refrigerant dryer using the refrigerant R-513A (GWP 631), which achieves a pressure dew point of +3 °C. This allows condensate to be separated right in the compressor—eliminating the need for separate compressed air treatment.

SX T Series – Compact Screw Compressors with Refrigeration Dryer (4.0 – 5.5 kW)

The SX T models combine a compact design with integrated compressed air drying. With a footprint of just 0.54 m², they deliver dried compressed air at a maximum pressure of 8 to 11 bar—ideal for commercial businesses and workshops with moderate compressed air needs.

SM T Series – Industrial Screw Compressors with Refrigeration Dryers (5.5 – 9.0 kW)

The SM T models are designed for continuous industrial operation. With drive power ranging from 5.5 to 9.0 kW and a flow rate range of 0.94 to 1.61 m³/min, they are suitable for production facilities with a continuous demand for compressed air. The SM 13 T features a particularly energy-efficient IE4 motor.

SK T Series – High-Performance Screw Compressors with Refrigeration Dryers (11–15 kW)

The SK T series delivers compressed air performance for demanding production environments. With drive power ranging from 11 to 15 kW and operating pressures up to 12 bar, the SK T models also cover high-pressure applications—with a flow rate of up to 2.46 m³/min.

ASK T Series – Screw compressors with refrigerated dryers for high airflow rates (15–22 kW)

The ASK T Series delivers air flow rates ranging from 2.38 to 4.05 m³/min at operating pressures of 8 to 15 bar (max.). With drive power ranging from 15 to 22 kW and an integrated refrigeration dryer, the ASK T models are suitable for industrial applications with high compressed air consumption and a simultaneous need for dry compressed air.

When is a screw compressor with a built-in refrigerated dryer the right choice?

A screw compressor with an integrated refrigerated dryer (model designation “T”) combines compression and drying in a single unit. This saves floor space, reduces installation effort, and lowers operating costs compared to a separate dryer solution. The integrated KAESER refrigeration dryers achieve a pressure dew point of +3 °C and reliably protect downstream compressed air consumers, lines, and tools from condensate and corrosion. Typical applications include painting, food processing, pneumatic controls, packaging machines, and any application where moisture in the compressed air could lead to quality issues or equipment damage.

SIGMA CONTROL 3 – Intelligent Control System for All T Models

All KAESER screw compressors with refrigeration dryers are controlled via the SIGMA CONTROL 3. The SX T models use the SIGMA CONTROL 3 S with SECOTEC connectivity, while the SM T and SK T models use the SIGMA CONTROL 3 M with a 5-inch touchscreen, AIRBOX.2 integration, and interfaces for Profibus, Modbus, Profinet, and AnyBus. The ASK T series is also controlled via the SIGMA CONTROL 3 M and additionally offers the i.Comp 8 and i.Comp 9 communication modules for seamless integration into higher-level control systems.

Recommended Accessories for Screw Compressors with Refrigeration Dryers

KAESER’s T-series screw compressors already feature a built-in refrigeration dryer with a pressure dew point of +3 °C—therefore, additional compressed air drying is not required in most applications. However, to ensure safe operation and protect the equipment, we recommend the following supplementary components: A Compressed Air Tanks is absolutely necessary—screw compressors must not be operated without a tank, as the tank absorbs pressure spikes, reduces cycling frequency, and ensures a steady supply. For particularly sensitive applications—such as in food processing or surface treatment—it is also recommended to use a Compressed Air Filtration to remove residual oil and fine particles.
