R404a brand screw type parallel compressor racks for apple and carrot cold storage

1. Because of a huge demand difference between seasons for refrigerating capacity, the unit must have a high level control for capacity, so that the unit can keep running under high efficiency mode. The average parallel unit efficiency, according to different refrigeration system is 30% higher than single compressor unit.
2. Using multiple compressor parallel units can provide a multiple energy level control, the refrigeration output can be dynamically allocated more smoothly according to actual situation.
3. With high efficiency oil separator, only a small amount of lubricating oil enters the system, this largely brings up the heat exchanging efficiency.
4. The PLC controller monitors running compressors quantity, it maintains a maximum use rate even when only parts of the compressors are functioning.
5. PLC controller can be set with the best running curve (maximum & minimum power comsuption), to same as much electricity as possible.
6. With “modularized design” the risk during construction can be largely reduced, construction period can be shortened, improve the product quality controllability.

Shandong Ourfuture Energy Technology Co., Ltd produces screw type  condensing units, screw type multiple compressor parallel units, reciprocating condensing units, reciprocating parallel compressor racks, scroll type compressor box type condensing unit and scroll type parallel compressor units with best quality and favorable price.

Our compressor units/racks can be used in cold room storage, blast freezer, fast frozen tunnel, retail refrigeration, cold chain logistics, chemical and pharmarcy area, fishery and shipping industry, etc. 

Our basic products include the following:
1. Single-stage reciprocating type parallel compressor racks(20HP~350HP) @7.5~45oC Tss.
2. 2-stage compressor reciprocating type parallel units(16~180HP) @-25~-65oC Tss.
3. Single-stage screw type parallel compressor racks(80~600HP) @5~45oC Tss.
4. 2-stage compressor screw type parallel compressor units(100~600HP) @-30~-65oC Tss.
5. Danfoss scroll type compressor box type condensing units and parallel compressor racks.
6. R744(CO2) cascade system compressor units.
(Refrigerant can be R744(CO2), R404a, R507, R407C, R22, etc. )

Our compressor racks and condensing units are equipped with world famous brand high quality components, we are distributor of , Carlyle, Fusheng, Bock, OEM factory of Danfoss. Key controllers and valves are Danfoss brand, contactors are Siemens brand. 

We also develop and program our own PLC control system, it can automatically control the running compressor quantity according to refrigeration need so that the system can save more energy and can provide 30% more use life than single compressor condensing units. With PLC auto control graphical interface, customer can operate with read the running status, data, parameter and error alarms easily. Optional remote control communication port is also provided, so that customer can monitor in their office. 

We focus on high efficiency daily mangement and QC to guarantee stable quality. By following ISO9001:2008, we have strict tracking system of each order, all welding are proformed with argon charged in the system to prevent welding waste going into the system. All condensers are delivered with high pressure gas charged when they delivered. Each final compressor rack will go through no-load test before packaging.

We welcome friends from all over the world, together let's serve the world with more environmental, efficient and cost effective refrigeration unit.
