RC2 Series Screw Compressor
High-efficiency Motor
- Available for part winding start or star delta start
- Custom-made for specified voltage and frequency
of power
- Two options A&B motor for RC2-100~RC2-930. Four options A1, A2 & B1, B2 motors for RC2-1020 ~1530.
- Optimal slot design for passage of refrigerant inside
motor casing
- Refrigerant flows through outside of motor winding to
provide the most efficient motor cooling
- Sliding-fit stator easier for installation and removal
Part-load Effective Economizer Operation
- Enhance cooling capacity as well as energy efficiency
- Sustain optimum medium pressure by vapor injection through specially-designed slots in slide valve and compression casing
- Effective under partial load and full load
Dual Capacity Control
- Flanged-on solenoid coil easy for installation
- 3-step / 4-step or continuous (33%~100% / 25%~100%)
capacity control system
- Interchangeable by varying control logic without modification of solenoid valves
Durable Bearing Structure
- High-quality bearings (radial and axial resistance)
- Additional bearing for backward rotation
- ∞ balance piston against axial thrust
- Heavy-duty design
- Longer bearing life compared to traditional 9-bearing design
Wide VI Selection
- Built-in volume ratio (VI)-2.2, 2.6, 3.0, 3.5, 4.8
- Exactly match pressure ratio without over-or under-compression
- Suitable for various applications like refrigeration, water-cooled chiller, air-cooled chiller and heat pump
High-performance Integral Oil Seperator
- Detachable demister for cleaning
- Finer size of mesh
- Low pressure drop and oil carry-over
- Three stage oil separation(RC@-1020~RC2-1530)
Complete protection & accessories
- Motor temprature sensor (optional)
1. "Built-in" Pt100 or Pt1000 installed in motor winding
2. Accurately registers motor temperature
3. Controller can precisely initiate liquid injection to motor accordingly
- Discharge temprature thermistor & motor temprature
thermistor
1. Totally integrated
2. Effectively protect compressor in advance when any abnormal alarm occurs
- Liquid injuction and oil cooler function (Port & Stop pin)
1.Both available on everyhanbell screw compressor
- Oil level switch
1. Ensure sufficent lubrication in compressor for better lubrication,capacity control, cooling and sealing
- Heater (150W & 300W)
1. Increase lubricant's flow-ability when compressor restarts afterlogin-term stop.
- Connection for pressure differential switch
1. Easily detect clog in oil filter
2. Assure effective capacity modulation and lubrication
Other Advantages
- Low noise level and minimum vibration
- Fewer quantity of parts in screw compressor than those in reciprocating compressor
- Easy for maintenance and overhaul
- Compact geometry, easy for layout
