Product Details
Lower-temperature chillers(-25)
The temperature range of low-temperature mechanisms is -25℃~35℃，fast cooling,safe
and reliable,can be used for gas,liquid rapid cooling.BESTEN low-temperature mechanisms is the newest
product which is widely used in chemical,pharmaceutical,biochemical and other industries.
1). Compressor is imported from Europe and America of the piston, scroll compressor, there Copeland, performance, power and durable
2). Expansion valves, filters, high and low tables, solenoid valves, gas-liquid separator, oil separator, pressure controller and other refrigeration components are used, such as Emerson, Castel drag, Danfoss, Europe, America, Japan and Taiwan Brand, high efficiency, the use of failure rate;
3). Selection of high quality low-temperature dry evaporator and plate heat exchanger, air-cooled condenser copper string of high-efficiency aluminum honeycomb, heat transfer performance; Efficiency; Adopt Microcomputer temperature control, develop independently, ordered by famous factory, have superelevation, low temperature and signal processing.
4). Machine is equipped with a reverse-phase protection, overheating and overload the compressor, pump overload protection, frost protection, high and low voltage abnormal protection, discharge protection device is also equipped with abnormal alarm and fault indicator warning buzzer, circuit can automatically cut off, safe and reliable.
