—— Product Description ——

Withair® offer water-to-water heat pump from 2 to 40+ tons.

Withair® Water to Water Source Heat Pumps can take low temperature heat and upgrade it to a higher, more useful temperature. If this heat comes from an ambient source, for example outside air or the ground, the use of a heat pump can result in savings in fossil fuel consumption and thus a reduction in the emission of greenhouse gases and other pollutants.

—— The key advantages Include —— 

● Multi-function: provide cooling only, cooling with hot water, heating only and heating with hot water, hot water, total and partial heat recovery for domestic hot water heating. 
● Unit choose efficient rotary or scroll compressor, the use of high efficient heat exchanger technology processing, condensation temperature greatly reduced, the COP is more 4.6 and higher 70% than air cooled heat pump.
● When multiple units were combined into a system, because each unit can be individually ON/OFF; wide range of system energy regulation and running costs fell by more 40%.
● Unique compressor anti-vibration technology and sound attenuation material ensure ultra-quiet performance. 
● Multi-system design and wear-and-tear management technology reduces electric impulse and extend service life.
● Modular network function: unit control system is equipped with the network communication, the user can control operating units quantity according to the actual use load, make user side water system utilities, to realize the automatic device management automation and energy management.
● Smart microchip control and large LCD user interface, capable of one-key startup. 
● Automatic intelligent reset. Unit shall automatically restart 5 minutes after shutdown if the fault has cleared. Should a fault occur 3 times sequentially, then lockout will occur.
● Humanized design, widened application scope: the unit’s temperature settings for room, hot water, water intake/outlet, freeze protection, and compressor exhaust can be adjusted on-site according to environmental conditions. 
● Communication adapter connection the unit to BMS(Building Management System) is an optional accessory, please get in touch with us or our distributor if required. 
● Unit with multi-protection to guarantee the unit running stability and security, such as: high/low voltage, low oil level protection, exhaust temperature, antifreeze, power lack/reverse phase,water system cut off. operating condition with small change range stable operation, safe, reliable and long service life.

● Easy installation,  simple water piping system configuration, you can make design partition and divide second installation
