5.Hanbell Screw Compressor Introduction
Hanbell RC2 series screw compressors feature simple and robust construction by elimination of some components such as pistons, piston rings, valve plates, oil pumps which are found in reciprocating compressors. Without these components,screw compressors run with low noise level, minimized vibration, high reliability and durability. RC2 series screw compressors are of two-shaft rotary displacement design with the latest and advanced 5:6 patented screw rotors. Screw rotors are precisely installed with roller bearings, i.e. radial bearings at both suction and discharge ends as well as angular contact ball bearings i.e. axial bearings at discharge end. A three-phase, two-pole squirrel-cage induction motor drives the compressor. The motor rotor is located on the shaft of the male screw rotor. Cooling of the motor is achieved with suction refrigerant vapor.
(1)Multinational patents of high-efficiency screw rotors
The new 5:6 high efficiency screw rotor profile is patented in Taiwan, UK, US, and China. This new large-volume, high-efficiency rotor profile is designed especially for modern refrigerant characteristics. High-efficiency screw rotors are accomplished by using precision CNC machining centers, rotor milling machines, rotor grinding machines. Strict ISO 9001 process controlling and the application of precise inspection equipment, such as ZEISS 3D coordinate measuring machines, ensure high-efficiency, high-quality, low-noise and low vibration RC2 series screw compressors.
(2)High efficiency motor
Premium grade low-loss core steel with special motor cooling slot and refrigerant guide vane
which pilot the cold suction refrigerant gas through the motor provides the highest operating efficiency possible no matter how strict operating conditions are.
(3)Long life bearings and high reliability
The screw compressors utilize a combination of 10 axial and radial bearings and α axial balance piston to ensure longer bearing life and higher compressor reliability.
(4)Double-walled rotor housing
Double casing structure with high strength inner ribs has been designed to minimize noise and ensure rigidity. The rotor housing is made of high-strength gray cast iron FC25 that is extremely stable, therefore no expansion will occur even at high-pressure condition. These casings are machined by computer aided machining centers and inspected by precision measuring machines to enhance reliability.
(5)Direct flange-on oil separator
A vessel made of ductile material FC 500 specially designed to withstand high pressure and provide the highest efficiency of oil separation. Simple oil management, three-staged oil separator(models above RC2-1020), low-pressure-drop demister to ensure the minimum refrigerant dilution in the oil and maintain high oil viscosity.
(6)Precise capacity control
The slide valve for capacity control is located in the compressor chamber. The slide valve is actuated by injection of pressurized oil into the cylinder from the oil sump as well as bypass of oil through solenoid valves in each oil lines with pressure differential.
(7)Perceptive protection modules
RC2 series screw compressors are equipped with PTC thermistors and motor protection module which could monitor discharge and motor coil temperatures as well as phase sequence and phase loss. Accessories also include oil level switch to monitor the level of oil, pressure differential switch, and pressure relief valve for optional application.
(8)Adaptable with additional cooling
Liquid injection connection port located at the motor casing and in the compression chamber, oil cooler connection port, and middle pressure economizer connection port for customer's desired application.

7. Requirements of chiller installation
The unit should be installed at a location that fulfills the following requirements:
(1)The unit should be in a special device room.
(2)The foundations must be level and stable enough to ensure that no vibrations or operating noises occur when the unit is in operation.
(3)The unit should be installed in such a way that it is only accessible to authorized, trained and technical
personnel, and use appropriate equipment to keep unauthorized persons away from the unit.
(4)There must be sufficient clearance around the unit to carry out maintenance or repair work.
(5)Make sure the leaking media do not damage the installation location or the environment.
(6)Choose the installation location so that operating noise does not cause a disturbance.
(7)There should be drainage around the unit foundation in order to drain out the water in the system when the unit stops or is in the maintenance.
(8)There should be no pipes or wiring pipe above the compressor.
