 MACUltra-low temperature freezer
Water cooledMAC-RCC-HWSeries low temperature can reach- 160.℃
The hot gas defrosting function
MACUltra-low temperature freezer is a powerful auxiliary exhaust system

Characteristics of < >
More heat exchanger series
System by means of refrigerant through multiple series of condenser, repeat condensation. The action of evaporation cooling.
The defrosting system
Carry by MAC standard patent technology (97100931), the defrosting and its efficient utilization system
, more stable operation.
Non azeotropic mixed refrigerant freezing method
Using the MAC patent technology (4108656), to prevent the low boiling point and high pressure gas pressure rise of the system
Carrying high pressure attenuation system.

MAC-RCC-HWA series of- 145 ~ 160℃

lowOperation panel

　RCC-HWAll series adopts touch LCD screen, simple operation and display all kinds of connections.
　
 

The main picture warnings

In addition, also have protection setting, maintenance, such as adjustment of almost all of the function, can in setting adjustment
Touch screen operation, easy to maintenance.

　
lowThe common specifications. The external signal input operation. The temperature of external output. The abnormal alarm output. The refrigerant piping ball valve

The condenser(condensation, condensation tube)

Condenser can be in accordance with the characteristics of the vacuum system, needs to carry on the design, not qualified to make the snake tube.
Condenser installation location should avoid thermal and optical radiation..Such as the heat source.

High vacuum unit = narrow area of condenser.
Base material contained more = increase the area of condenser water.
High temperature heating vacuum unit = condenser area of 70%。
Refrigerant piping (refrigerator < = > cavity)

Constitute the important key to realize ultra-low temperature, please according to the company technical guidance.

Pipe size and distance

Piping is inversely proportional to the distance and cooling efficiency.
The long distance to the most low temperature time longer, should as far as possible, shorten distance piping.
