The temperature range is from -10 °C to -60 °C, which can meet different temperatures;
All use environmentally friendly refrigerants;
Using secondary subcooling technology, the refrigeration is rapid and the limit temperature is low;
It adopts imported famous brand semi-closed piston compressor, semi-closed piston two-stage compressor and semi-closed screw compressor. The main self-branding is BOCK, Bitzer, Copeland, Hanbell, fusheng; the evaporator uses high-force plate heat exchanger, which is small in size. efficient;
Use a full set of imported cold controls (DANFOSS pressure controller, balance valve, expansion valve, solenoid valve, dry filter, Emerson oil separator, ALCO sight glass, check valve, etc.);
The unit cooling water circuit uses an intermediate heat exchanger to significantly improve the reliability and safety of the system;
The DANFOSS electronic expansion valve has high control precision;
Using Siemens PLCS7-200/300 PLC, LNEYA touch screen display, automatic control operation, with temperature curve display, temperature record U disk, fault alarm record;
The large-cooling unit adopts a semi-closed screw compressor with an economizer, and is combined with an electronic expansion valve to ensure high efficiency and energy saving;
The whole machine is installed. The system has been tested in the factory. The user only needs to install the coolant pipethe cooling water pipeun.
Factory test: Each refrigeration unit is tested at the factory with a load of not less than 12 hours;
The medium-sized single-fluid low-temperature freezer produced by our company has a cooling temperature range of -10°C~-60°C, fast cooling speed, safe and reliable, and is used for rapid liquid cooling. It is widely used in petrochemical, medical, rmaceutical, biochemical, freeze-drying, High-tech industries such as rmaceuticals and military industries.
Application areas:
Low temperature reaction in chemical, rmaceutical, biochemical and other industries
