TTK 8/60W-1-P low-temperature chiller – 4 kW refrigeration system down to -70 °C for extremely low temperatures

The TTK 8/60W-1-P deep-freeze unit is a specialised refrigeration system designed for applications in the extreme low-temperature range. With a cooling capacity of 4 kW at -70 °C and a temperature range of -70 °C to -40 °C, this system is suitable for processes where conventional deep-freeze units or chillers are no longer sufficient. This is based on the unit’s specifications, which include two-stage refrigeration technology and temperature-dependent capacity control.

The system has been specially developed for industrial applications requiring very low temperatures. By using special refrigerants such as methanol or ethanol, stable processes can be achieved even at temperatures well below -40 °C.

Low-temperature chiller for extremely low temperatures down to -70 °C

Whenever processes require temperatures well below freezing, the TTK 8/60W-1-P really comes into its own. The machine reliably achieves temperatures as low as -70 °C, making it suitable for highly specialised applications.

The cooling capacity is designed to be temperature-dependent:

• 10 kW at -40 °C
• 8 kW at -60 °C
• 4 kW at -70 °C

This makes the system ideal for precise cooling processes in the extreme low-temperature range.

Two-stage refrigeration technology for maximum performance

The TTK 8/60W-1-P uses a two-stage refrigeration system to achieve these extremely low temperatures.

The following components are employed:

• Refrigerant R449A (Stage 1)
• Refrigerant R23 (Stage 2)
• 1 refrigeration circuit

This combination ensures stable operation even at very low temperatures and delivers reliable cooling performance under demanding conditions.
