A Professional HVAC Supplier and Your Business Supporter

Hello, this is Wesley, the CEO of Tech Well Industries Co., Limited. The free document will be sent to you in about 12 minutes.


Here I would like to ask whether you met this situation? You used the air cooled chiller and heat pump for heating in winter. But the unit performance is becoming worse and worse as the ambient temperature decreases. When the ambient temperature close to 0℃, you cannot get much heating result from the unit. The ambient temperature drops further to -7℃ the unit stop working. There are may be some products may work until -15℃. But the performance is not satifactory.


This situation happens because it is the basic technical feature of the common air cooled chiller and heat pump. It is limitation of the technology. A new technology has to be applied if we want to solve this problem.


I would like to bring Tech Well EVI Air Cooled Modular Chiller and Heat Pump to you here. The series chillers can work at the ambient temperature as low as -30℃ in heating mode. It can satisfied majority occasions heating with chiller and heat pump units.

Air conditioning units are so great products that help offering people a comfortable life. It is a pity most manufacturers are just offering very basic products which cannot meet the usage requirement in some special occasions, such as heating in ambient temperature below 0℃. Tech Well is set up to offer as much solution as we can to support business of our customers.
