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. More heat exchanger series
Refrigerant gas.N2 + HFCEnvironmental mixed refrigerant 
specifications 
* specifications are subject to changes without prior notice
* minimum temperature of the measured temperature of the no-load condition
* minimum temperature to the low temperature time, due to the surrounding temperature, temperature change and there are different
* standard color to light gray/black, the coating color can be changed 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
type | SIZE | Piping length limit | | 351RCC | 1/2 | < 5M | | 751RCC | 5/8 | | 1101RCC |
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.
MACUltra-low temperature freezerisPowerful exhaust auxiliary systemwith20In history, and500The above achievements.
Production capacity30%The above.
The realization of high quality film.
High temperature of film forming process can also be used.
ｒｅｐｌａｃｅ the use of liquid nitrogen.
