Product description

 industrial water cooled screw chiller Workshop live-action
      product description   It is one kind of steam compression refrigeration units. It mainly consisting of centrifugal compressor, shell and tube condenser, full liquid shell and tube evaporator, throttling device, lubricating oil system and microcomputer control system.   It can be widely used in comfort central air conditioning system for communal facilities like hotel, shopping mall, office building, exhibition hall, airport, gym etc. Meanwhile, it can meet the various requirements of process air conditioning system for industries like electricity, pharmacy, biology, light textile, metal and mechanical industries etc.   Because it has large single capacity, it is mainly used in occasions with large cooling capacity.   Working principle   The steam refrigerant flows into the induction chamber through induction tube and enters into rotation impellers. The blades will push the air flowing from center to out along the flow passage for the high speed rotation of the impellers. As the air flows out from the impellers, both its pressure and absolute velocity increases. And then the speed energy will change into pressure energy. Finally, the air from the pressure diffuser will gather in the volute in which the speed energy will further change into pressure energy. The air with high pressure will exhaust into condenser through exhausting pipe.   Its features:   1. Using R134a refrigerant, without limit of service life.   2. Using twin-stage centrifugal compressors, with high energy efficiency ratio.   3. The power supply can be 380V/6000V/10000V.   4. Using Siemens microcomputer intelligent control unit.   5. Various throttling control schemes.   6. Using liquid level intelligent control.   7. Independent oil return system.   8. Compact design, small covering area and low noise.   The standard operation conditions:   1. Nominal conditions:chilled water in/out temperature: 12°C/7°C; cooling water in/out temperature: 30°C/35°C.   2. Fouling coefficient of evaporator: 0.018  square meter  °C/kw; condenser 0.044 square meter  °C/kw.   Company Information    Shandong GRAD Group Co., Ltd. is located in Dezhou city, Shandong Province,covering an area of 450,00 square meters. It is a large modern enterprise group with central air-conditioning, ventilation, FRP products research development, design, production, sales, installation and maintenance.It is the backbone enterprise of "Dezhou • Central air-conditioned city" named by China Refrigeration and Air Conditioning Industry Association(CRAA). GRAD Group products include: central air conditioning series products(chillers, air conditioners, fan coils, cooling towers, ventilators and accessory products), FRP series products (FRP winding pipes and storage tanks), SMC moulding products (water tanks, table tennis boards, basketball boards, manhole covers, etc) . All products have been inspected by the national quality inspection department.     Packaging&shipping  Usually we use plywood package or naked package. Some of the products like fan coil unit or table tennis board have standard carton package. The shipping terms are LCL, 20’ container, 40’ container. 
    our services     1,we can deliver the sample by international express.You should pay the sample and express cost 2,We can provide you installation guide. 3,If parts are damaged in the quality insurance period because of our quality,we can change the damaged  parts free of charge.   FAQ   1. Product warranty: Usually, our product warranty is 18 months after leaving factory or 12 months after installation.   2. Delivery time: It will depend on the product quantity. Our products are sold according to order.    3. Installation: If the project needs our installation guidance, we can send our engineer and translator. The expenses shall be borne by the project owner.    Our product marketing at home and abroad   GRAD group set up in the major cities to marketing services platform, let the customer get more satisfactory service.
