Bitzer Germany company is the world famous refrigeration equipment manufacturers, its than zell compressor and complete refrigeration equipment with superior performance, high quality and high reliability is famous in the world refrigeration industry.Its main features:
1, special valve design, high stability, long service life.   
2, large capacity, can effect comparing (COP) is higher than other brand compressor is 20%;
3, good low temperature performance, for R22 refrigerant, single stage compressor evaporation temperature can reach to 40 ℃;       
4, used in a variety of refrigerant (R12, R22, r114, everything, R404A, R507), comply with the requirements of environmental protection;
5, using coil start, reduce the starting current, reduce the impact on the grid, the motor with special design parameters and the development of new words and the rotor parts, increase the efficiency and power factor;
6 and wide range of application: than zell compressor is divided into the high temperature and low temperature, high temperature type evaporating temperature of 12.5 ℃, low temperature type single stage compressor evaporation temperature can reach (R22) - 40 ℃, two-stage compressor evaporation temperature can reach (R22) - 50 ℃.Such as using R404a or R507 evaporation temperature is lower, to - 70 ℃. 

Germany's treasure vacuum pump (tianjin) lai treasure company is one of the world's largest vacuum equipment suppliers.Germany's "core" technology, the equipment has high reliability.

Grundfos circulation pump, grundfos is the world pump industry, one of the leaders in its capacity every year nearly 16 million units.Used for heating air-conditioning circulation pump, used for industry, water supply and wastewater treatment of centrifugal pump and the metering pump is the main product.Today, grundfos is the world's largest production factory circulating pump, such pumps products covers about 50% of the world's market.

Danfoss expansion valve the main characteristics
1, the evaporation temperature range: 60 ℃ to + 50 ℃ can be applied to freezing, refrigeration and air conditioning. 
2, interchangeable LiuKou components: easier to inventory, facilitate matching capacity and better service. 
3, when used for R22, nominal refrigerating capacity from 0.5 to 1890 kw (0.15 to 540 tr). 
4, can provide the MOP (maximum operating pressure) protect the compressor motor limit function, prevent the damage due to excessive evaporation pressure.
