7.FAQ
Q:What is air handler?
A: An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system.
 
Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork.

Small air handlers, for local use, are called terminal units, and may only include an air filter, coil, and blower; these simple terminal units are called blower coils or fan coil units.

A larger air handler that conditions 100% outside air, and no recirculated air, is known as a makeup air unit . An air handler designed for outdoor use, typically on roofs, is known as a packaged unit or rooftop unit .

Q: What information do you need to provide in order to get a quotation?
A: Generally, we need to know following items:
-Cooling Capacity in KW or RT or Btu
-Cold water conditions if available is better
- Local ambient temperature conditions
-Application
-Electrical power supply, such as 380V-3Phase-50HZ or 440V-3Phase-60HZ or others.
 
If can not give full answers for above items, we can via another way, such as room or building drawing,application,etc
Q: Can I have a sample for testing before ordering products?
A: Yes, you can.And you are warmly welcomed to visit our factory before PO.

Q: What is the warranty of products?
A: Warranty: 12~24 months after Bill of Lading date. Any unartificial failure occurred within the period, we'll supply you the spare parts for free, and permanent technical support & consultation all life long for the machines
