Ultra-Low Temperature Circulating Chiller
Highly suitable for jacketed reactors used in low-temperature reaction materials requiring ultra-low temperature circulating cooling liquid, maintaining low-temperature reactions; compatible with 20L, 50L, 100L double glass reactors, cooling the reactor contents down to -70℃ or -80℃.
● Microcomputer control with full digital Chinese display, easy to operate. High-brightness LED temperature display. High and low voltage protection, overload protection, and overcurrent protection functions.
Fluorine-free refrigerant, compliant with EU and national standards.
● Refrigeration system compressors, oil separators, solenoid valves, expansion valves, etc., all use imported brands.
The evaporator is a fully brazed plate heat exchanger.
Low-temperature circulating pump, no leakage or stalling under low-temperature operating conditions.
● The recirculating system utilizes an enclosed recirculation system. No volatiles to protect experimenters' health.
The storage tank and refrigerant medium are both made of 304 stainless steel, offering excellent corrosion resistance.
The machine is stable and reliable, capable of meeting the demand for process cooling sources in continuous production for over 24 hours.
● The main unit is cooled by air cooling.
● The shell is electrostatic spray painted SPCC, with excellent corrosion resistance.

Safety Protection | Features include self-tuning function; overload protection for the refrigerator; high-pressure pressure switch; overload relay; thermal protection device, and various other safety functions. | |||||
Sealed Recirculation System | The entire system is fully enclosed, producing no oil mist at high temperatures, nor does it absorb moisture from the air at low temperatures. It does not increase pressure due to high temperatures when not in operation, and automatically replenishes the heat-conducting medium at low temperatures. | |||||
