Refrigeration Dryers
Kaeser refrigeration dryers provide dependable moisture protection down to a pressure dew point of +3 °C. Built to suit a wide range of applications and ambient conditions, the range includes energy-saving thermal mass dryers (SECOTEC), compact models for point-of-use (KRYOSEC), high-pressure systems (THP), and cold-air dryers (TCU) for process cooling. All units feature robust components, low pressure losses, and options for ECO-DRAIN condensate drainage, ensuring performance, reliability, and energy efficiency.
SECOTEC Refrigeration Dryers
Smart energy-saving dryers for flow rates up to 98 m³/min
The SECOTEC TD, TE, TF, and TG series use thermal mass storage and the SECOPACK LS system to manage partial-load operation with maximum energy efficiency. The SIGMA CONTROL SMART controller enables intelligent control and easy integration into SIGMA NETWORK. TG models extend the range to larger industrial applications with optional air or water cooling.
- TD/TE/TF Series: 5.1 – 34 m³/min
- TG Series: Up to 98 m³/min
- Pressure dew point: +3 °C
- Ambient temperature: Up to 43 °C
- Refrigerant: R-513A
- Includes SIGMA CONTROL SMART, ECO-DRAIN, SECOPACK LS
- Corrosion-resistant aluminium piping and heat exchangers
- Optional Modbus TCP for networking
KRYOSEC Refrigeration Dryers
Compact, decentralised dryers up to 4.5 m³/min
The KRYOSEC range delivers efficient drying for point-of-use installations and decentralised systems. Designed for ambient temperatures up to +50 °C, these rugged units use stainless steel heat exchangers and can be wall-mounted (TAH series). Ideal for smaller systems requiring safe and stable dew point control with minimal footprint.
- Flow rate: 0.35 – 4.5 m³/min
- Working pressure: Up to 16 bar
- Ambient temperature: Up to 50 °C
- Dew point: +3 °C
- Heat exchanger: Stainless steel plate-type
- Optional: ECO-DRAIN and dew point warning systems
- EN 60204-1 compliant (machine safety standard)
- Lockable power switch and isolating device
High-Pressure Refrigeration Dryers (THP Series)
Dependable drying up to 45 bar and 85 m³/min
The THP series is engineered for high-pressure applications such as PET container production. With stainless steel heat exchangers, low pressure loss piping, and a high-pressure ECO-DRAIN 12, these dryers maintain stable dew points with low energy consumption. All models use climate-friendly R-513A refrigerant.
- Flow rate: 8.5 – 85 m³/min
- Working pressure: Up to 45 bar
- Pressure dew point: +3 °C
- Inlet temperature: Up to 50 °C
- Ambient temperature: Up to 43 °C
- Refrigerant: R-513A (low GWP)
- ECO-DRAIN 12 (high-pressure version)
- Flow-optimised stainless steel piping
Cold-Air Refrigeration Dryers (TCU Series)
Process cooling with discharge air down to 5 °C
The TCU series is designed for applications that require cold, dry compressed air for process cooling – such as glass and metal moulding. These dryers include stainless steel heat exchangers and ECO-DRAIN systems. Higher models feature electronic control with multilingual display and optional remote monitoring.
- Flow rate: 4.3 – 43.33 m³/min
- Compressed air discharge temp: 5 °C
- Pressure dew point: +3 °C
- Ambient temperature: Up to 43 °C
- Inlet temperature: Up to 55 °C
- ECO-DRAIN condensate drain included
