Product features
Brand electronic expansion valve is adopted to regulate the flow and pressure of refrigerant more accurately, so that the refrigerant can evaporate more fully and absorb the heat in the air, greatly improving the energy efficiency ratio (COP) of the unit;
The spiral coaxial heat exchanger has higher heat exchange efficiency and is not easy to scale;
The key components are all products of listed companies, which are stable, reliable, durable and quality guaranteed;
Perfect unit protection and complete engineering supporting functions: high and low pressure protection, over-current protection, exhaust high temperature protection, phase sequence protection, water shortage protection, antifreeze protection, crankshaft heating and other multi egg protection functions, as well as water level display, timing water supply, constant temperature water supply, timing water supply, return water, timing switch, wire switch and other functions;
According to different regions, we can choose the model suitable for ambient temperature range: Standard Model (- 5 ~ 45) ° c) Low temperature (- 15 ~ 45) ° C) Ultra low temperature (- 25 ~ 45) ° C, jet remelting).
