Products

Highly Effective and Energy-Saving:
Features:Go through PLC and single chip microcomputer control, the unit can adjust automatically to provide multi-stage refrigeration capacity output, with the implementation of dynamic load automatic matching, which is the unit always works effectively and saves energy.
Refrigeration Capacity Range: refrigeration capacity from 18kw to 560kw, according to customer's demand to design unit
Application refrigerant: suitable for R22, R404A,R507A and etc.

 

 

Highly Effective and Energy-Saving:The main spare parts and components are famous brand products in domestic and abroad,the system work stable and reliably.
Automatic control system of unit is controlled by imported programmable logic controller(PLC)or single-chip microcomputer(SCM), and realize automatic safety protection in case of open phase,over-voltage,under-voltage,over-current,oil pressure,high pressure,low pressure and electric motor overloading. With PLC control, the compressor balance operation time automatically, so as to prolong its service life. Remote alarm and monitoring interface can be reserved according to users' requirements.

Compact Structure: with compact design concept,the unit occupies a small installation area. Provide "modularized"installation, lessen installation period,reduce pipeline consumables and shorten on-site construction period.

Reduce Cost::Realize automatic control of refrigeration system, and reduce daily operation and management cost.
Reduce investment cost of equipment and machine room area.
Enhance automatic safety performance,reduce the cost of auxiliary safety equipment.
Compared with traditional ammonia system,the unit reduce the maintenance cost
