FAQ
Q1: What information do you need to provide in order to get a quotation?

A1: For industrial water chiller we need to know the following information in order to suggest the suitable water chiller models and for providing the quotation.

-Air cooled or water cooled?
-Cooling Capacity,___Tons,___KW,___Kcal___BTU
-Power Supply_V_Phase_hz
-Refrigerant,R22 or friendly R410a,R407C
-Chilled water outlet temperature.
-Evaporator need pipe coil type or shell and tube type.
-With water pump and water tank or not.
-Order Quantity etc.

Q2:How does a chiller system work?
A2:Chiller has two circulation,one is process water circulation,the other is refrigerant gas circulation.Heat picked up from the process.Heat transfers to refrigerant circulation.Heat is remove to air or water.

Q3.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)

Q4:Cooling capacity unit conversion?
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,

Q5:The chiller Warranty.
A5: 12 months warranty, if there are problems with the machine parts. We provide free accessories
and delivery to customers.

As a professional industrial chiller manufactuer and solution provider , we can supply kinds of chillers to meet your different cooling requirement, if the chillers above is not workable for you, please feel free send needs to us directly.
