• The secondary refrigeration system cools methanol and other media down to -75°C, making it suitable for low-temperature applications.
• In addition, the PID control system maintains stable temperature control and achieves a temperature stability of ±0.05°C even at -50°C when users use methanol as the media solution.
• Furthermore, the unit includes comprehensive safety features. The leakage circuit breaker helps prevent accidents caused by insulation failure or overcurrent, while the light-sensor liquid-level alarm detects drops in the tank liquid level and helps prevent dry heating.
• Moreover, users can install the optional circulating liquid pump to circulate and supply cryogenic liquid to external equipment.
• Additionally, the 100 V, 20 W anti-condensation heater prevents condensation from forming on the top surface.

• The secondary refrigeration system cools methanol and other media down to -80°C, making it suitable for applications that require ultra-low-temperature conditions.
• In addition, the PID control system maintains stable temperature control and achieves a temperature stability of ±0.05°C even at -50°C when methanol is used as the media solution.
• Furthermore, the unit includes comprehensive safety features. A leakage circuit breaker protects the power supply from accidents caused by insulation failure or overcurrent, while a light-sensor liquid-level alarm detects low liquid levels and helps prevent the heater from operating without sufficient liquid in the tank.
• Moreover, the unit supports external circulation. When users install the optional circulating liquid pump, they can circulate and supply cryogenic liquids to external equipment and systems.
• Additionally, a 200 V, 20 W anti-condensation heater prevents condensation from forming on the top surface, thereby improving operational reliability and convenience.

By employing a dual-stage refrigeration system, it is possible to circulate ultra-low temperature liquid at -70°C to the outside.

• Cooling capacity: Minimum operating temperature -70°C, with a cooling capacity of 350W (when liquid temperature is -50°C).
• The circulation pump, which is also used for agitation, is a 60W motor-driven, seal-less pump that can be used safely for extended periods. The pump has a maximum head of 3m, a maximum flow rate of 15L/min, and a maximum discharge pressure of 0.03Mpa.

Usage example

It is used for low-temperature testing and storage of samples, indirect cooling of low-temperature containers, and as a stable cooling source as an alternative to dry ice.
