Features:
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 pipeline and the cooling water pipeline to run.
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 -10C~-60C, fast cooling speed, safe and reliable, and is used for rapid liquid cooling. It is widely used in petrochemical, medical, pharmaceutical, biochemical, freeze-drying, High-tech industries such as pharmaceuticals and military industries.
Application areas:
Low temperature reaction in chemical, pharmaceutical, biochemical and other industries
