Special purpose heat exchanger assembly for matching high efficiency optimization. Combined with the best system design and high precision cleaning assembly process to ensure the full use of energy efficiency
  • Fin type condenser: the wind side heat exchanger adopts the purple copper tube and the hydrophilic corrugated aluminum foil, which is closely connected with the machine
  • Shell tube evaporator: heat exchanger using the latest CAD/CAM design and processing technology, with CNC machining center to complete. the water blocking plate increases the turbulent flow effect of the freezing water Through special processing, the design of the evaporator inlet makes the refrigerant distribute more evenly in the exchanger tubes, the heat transfer effect is more prominent, and the energy efficiency ratio is higher. The shell has stainless steel / carbon steel /PP plastic etc for your choice.
  • Axial fan: used famous brand products, the fan is aluminum shell copper core low speed motor with high elevation multi blade structure which has many advantages of large capacity, high pressure, low noise, maintenance free, long service life etc. install automatic control device according to demands in cold area.
  • Electrical components: electrical components and contactors are used in the world famous brand, the temperature control unit uses the professional field of high-precision controller, the protection function is complete, to ensure the long-term stable and reliable operation of the unit
  • Fluid components: choose international brands pipeline pump, water storage tank of high quality SUS/304 stainless steel, stainless pipe through the strict control of the assembly process, no any leaking.
Comprehensive safety protection to make the unit more reliable operation :
1. The refrigeration system of the high and low voltage protection, overheat protection, safety valve protection.
2. Compressor overload soft and hard dual protection.
3. Lack of phase, reverse phase, under voltage, over voltage protection.
4. Anti icing protection of water system, less water flow protection, etc.

Made to measure: Make special model according to the different operating conditions in various industry. Such as: machine size, unit coolant (water, salt, acid resistance, alkali corrosion) and unit water flow / pressure can be designed and manufactured according to the actual demand. The outlet temperature of the unit can be selected from various models of -40 ºC to 30 ºC, and can be widely chose to meet the various needs of customers.

The unit is widely used in: aluminum oxide, aluminum oxide, electroplating, hard plastic, injection molding, extrusion, foaming machine, hydraulic equipment, laminating machine, bottle blowing machine leather embossing machine, composite flooring, food, chemical, biological, pharmaceutical, electronics and other industries
