Product Overview

—— Product Description ——

Withair® is proud to offer an extensive line of water-cooled mini chillers ranging from 2 to 40+ tons. The water-cooled mini chillers feature a variety of models and options engineered to fit a wide range of applications. Withair® water-cooled mini chillers are ideal for customers who are focused on high energy efficiency, superior reliability and long equipment life. Withair® products within the unique portfolio are designed to help lower environmental impact with next-generation, low global warming potential refrigerants and high-efficiency operation.

Withair® Water Cooled Mini Water Chiller is special designed to be small and medium size for central air conditioning system,It can also provide domestic hot water, industrial cooled water and hypothermal water for the technical manufacture. and is widely appropriate for separate management buildings, small and medium size office, factory workshop, restaurant and villa, etc, it also can be customized to equip with multi compressors and more energy saving and durable than split air conditioners.Every modular unit has it own independent refrigerant system and control and protection system, applies step by step system to meet the loading capacity. The unit applies efficient hermetic type scroll compressor, low noise, small vibration, high EER and Microcomputer control. Besides, we manufacture R134a,R407C,R404A,R410a environmental friendly refrigerants, products with seawater source and non-standard power supply.The unit is suitable for installing in the outdoor, i.e roof; balcony and porch, which could save the boiler room and the special room; decrease the investment of building project and easy to install, manage and maintain.

—— The Key Advantages Include —— 

● ECO friendly refrigerant R410a, R407c.
● Flexible configurations with top or side piping and  front or side control box.
● Large panels for accessibility to compressor and controls sections
● Plate type, coaxial tube-in-tube or shell and tube heat exchanger for high performance, reliability, and resistance to freezing.

● 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.
