  • 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.
