Product Q&A

Q:What information is needed for a quotation?

We need to know: Air cooled or water cooled? Cooling Capacity (Tons/KW/Kcal/BTU)? Power Supply (V/Phase/hz)? Refrigerant type? Chilled water outlet temperature? Evaporator type (pipe coil or shell and tube)? With water pump and tank? Order Quantity.

Q:How does the chiller system work?

The chiller has two circulations: process water circulation and refrigerant gas circulation. Heat is picked up from the process, transferred to the refrigerant circulation, and then removed to air or water.

Q:How to calculate cooling capacity for chillers?

Cooling Capacity (kw) = Flow Rate (m3/h) * Temp Change (T1-t2) / 0.86. Heat Load = C (specific heat) * M (quality output per hour) * Temp Change (T1-T2).

Q:What are the cooling capacity unit conversions?

1 USRT = 3.517 kW; 1 kW = 0.28434 USRT; 1 kcal/h = 3.968 Btu/h; 1 Btu/h = 0.252 kcal/h; 1 USRT = 3024 kcal/h; 1 kcal/h = 1.163W; 1 Btu/h = 0.2931W.

Q:What is the warranty period and coverage?

We provide a 12-month warranty for machine parts. If there are problems, we provide free accessories and delivery to customers.
