FAQ

Question 1:Can it be used in extremely cold weather?

Answer:It adopts jet enthalpy increate technology and can operate at an ambient temperature of -30 degree to 25 degree.

Question 2:Regarding environmental issues?
Answer:The heat pump unit using R410A (low temperature grade) and R134a/R515B (high temperature grade) environmentally friendly refrigerants, with zero ODP value, non-toxic and non flammable, and environmentally friendly. Among them, the GWP value of R134a refrigerant is 1430, and R515B is a new generation of environmentally friendly refrigerant with a GWP of only 299, which has a lower global warming potential compared to the former.

Question 3: About managing heat pump units?
Answer:PLC control with multiple operating modes, manual,automatic and remote control.

Question 4:The MOQ of our products?
Answer:1 piece.It depends on your needs.

Question 5: About Customization?
Answer:Provide integrated solutions based on the environmental requirements of customers, such as adjusting product size, performance, parameters, etc.
