Kobelco 2-stage screw compressor rack with VFD for -45 deg C freezer tunnel based on R404a/CO2

Use environmental secondary refrigerant CO2, ODP=0, GWP=1Refrigerant: R404a, R717.Refrigeration capacity: 40KW~500KW.Application: Super low temperature cold storage, super low temperature brine system, fast frozen, etc.

Equipped with inverter, it settles the problems of requiring very large start-up power supply and start interval more than 10 mins. The Inverter type unit can be on/off at any time. It can reduce the impact to the power grid by reducing the installed power. Equipped with large capacity heat/cold exchanger, can super-cold liquid and also effectively prevent liquid returning to compressor. Pump station liquid supply, it can be used for long distance liquid supply, simplify the system while offering a clear and easy control. The evaporator side uses CO2 as secondary refrigerant. It’s non-toxic, anti=flaming and has large latent heat of evaporation. Advanced user interface and control system with 10 inch PLC color touch screen display. With multi-touch function you can easily swap, enlarge just like using your ipad. It also support remote monitoring include data checking, modifying and downloading, it brings convenient to user.

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.
