Product Application
The integrated cooling and heating machine is a circulating water temperature control device that combines cooling and heating. It has a complete set of cooling system and heating system. You can choose to turn on the cooling system or the heating system under different needs. In this way, the temperature control requirements under different working conditions can be met.
Dawoxi DW-HA series integrated cooling and heating units are widely used in reliability aging tests, new material synthesis, scientific research and other equipment or process links that require refrigeration and heating.
Main features
1, Small size, light weight and easy operation.
2, According to production needs, it can provide cooling circulating water to cool the equipment or provide hot water to increase the temperature, and the temperature can be kept constant between ±1℃. One-button operation, easy conversion, fast temperature increase and decrease speed.
3, The main unit is made of brand new imported compressors from the United States and Japan, with built-in safety protection, low noise, stable and durable.
4, The electrical parts are all original products of the international brand "Schneider".
5, Stainless steel open water tank, easy to clean and maintain, sturdy and durable.
6, Complete protection measures, intelligent fault indication, buzzer alarm. High degree of automation, no need for special operation.
7, Novel design, easy to move, simple to operate and maintain.
