Design characteristics

  • Refrigerated & air system is accurate calculated by professional designing engineer, keep 20% capacity.
  • Pipeline is made from inner zincification. You can choose working pressure during 0.3~4.5Mpa.
  • Stainless steel pipeline, it's suitable for medicine, food stuff, acid-resistant, alkaline-resistant and erodent-resistant industry.
  • Ripple pipeline of both internal and external of the heat exchanger to increase the using rate of cooling air, adverse current structure, perfect returning temperature and it won't freeze.
  • Evaporator is made from laminose copper pipeline with aluminum flake, high efficiency of heat exchanging of the perfect structure.
  • Good drainage, it adopts 3 grades for draining, can drain lots of condensate water and oil contaminant so as to keep clean and dryness of the system and air, meanwhile reduce system load.
  • Multi-control of circuitry to supply to different users (single control; integrate circuit, linkage control, PC panel, frequency conversion, etc.)
  • Outer cooling fan with large volume, low noise, and long life if switch frequently.
  • Low condenser made from copper, slow flow, multi-cycling and high heat exchanging rate. It won't freezing and dirty if stop for a long time.
  • Armstrong foam burning resistant & adiabatic material. It's the least loss of cooling air.
  • Protection level of compressor is IP54 (dustproof and spill proof).
