Plate - Fin Typed Air Cooled Screw Chiller With Riou Compressor

Air Cooled Screw Chiller Feature :

1.The plate-fin typed air-cooled condenser applies double-curved corrugated aluminum foil. Which is water-contactable. It is manufactured by specialized heat exchanger processing machine. Thanks for being extremely compact and light weight. As well as the high heat exchange efficiency and the ventilator with large rachis in slow revolution, the working noise level is obviously reduced so that the equipment is more environmental-friendly.

2.Imported programmable logic control panel(PLC)is used for the unit control system. The human machine interface configures a large touch screen. Which enables easy and visual operation.

3.The unit control system adopts a reliable safety protection equipment. E. G. high/low voltage protector. Ventilation overheat protector. compressor electically protector over-current protector. Water flow protector. Emergency switch. Thermal sensitive soluble chock. Safety valve. Etc.

  Components

1. Compressor

RIOU use the famous compressor, like Bizer, Copeland, Danfoss, SANYO, Taiwan Hanbell and Taiwan Fu Sheng, to ensure the quality. RIOU believes that diversified choices can meet most of the clients.Usually, RIOU will use scroll compressor for small-medium cooling capacity, screw compressor for large cooling capacity and piston compressor for low temperature working situation.The output power of screw compressor can be controlled automatically by control system. Furthermore, there are four phases for choosing: 0%-25%-50%-75%-100%. And the motor of the screw compressor is star delta start.

2. Throttling Gear

According to the cooling capacity, the chiller will adopts capillary tube or thermostatic expansion valve. The capillary tube will be made by us. And the expansion valve will be Emerson or Danfoss brand. 

3. Control Panel

Normally, scroll chiller is equipped key control panel with LED display and screw chiller is controlled by touch screen (human-machine interface). You can choose Punp (usual), Siemens or Mitsubishi brand. According to your needs, the chiller can be long-range controlled. 

4. Condenser

RIOU air cooled scroll chiller adopts finned type condenser; screw chiller adopts brass sleeve corrugated aluminum fin type condenser. The refrigerant will be cooled down here by the fan. Usually, the fan is on the top of the chiller. But it can also be on the side of the chiller according to your special needs.Please notice that the finned condenser can be corroded by corrosive gas. Therefore, you’d better choose water cooled chiller or you should find a way to avoid the corrosive gas contact with condenser. If the local environment is windy and dusty, the chiller should be equipped dust gauze to protect condenser.Some clients don’t want the chiller’s quantity of heat be emitted in the workshop. In consideration of this situation, we can separate the condenser from the chiller. So that the cooling part works inside the workshop while the heat dissipation part works outside. 

5. Evaporator

You can choose coil tube type or shell and tube type. Shell and tube type evaporator is more efficient than coil tube type. If you choose coil tube type evaporator, the chiller should be equipped a water tank. The chiller will need a water supplement tank according to some situations too. In consideration of corrosive liquid, the evaporator can be titanium coil tube type or stainless plate type. 

6. Water Pump

The water pump type will be decided by your needs. For example, if the chiller needs to cool corrosive liquid, it’ll need a chemical pump.

7. Water Tank

RIOU can provide different capacity of water tanks for clients to keep the liquid temperature in the water tank.

8. Others

Danfoss electromagnetic valve, Emerson filter, LG contactor and LG thermal relay.
