Introduction
The Hanbell RC2-F series semi-hermetic twin-screw compressor inherits all the quality and experience of our
RC2 series compressor. The RC2-F series compressor is developed especially for application with Freon in
flooded system or refrigeration field. With a built-in high operating load design and advanced 5 to 6 Patented
Screw Rotor Profile, each compressor has high efficiency and reliability in all operating condition. Each unit is
carefully manufactured and inspected by high precision THREAD SCREW ROTOR GRINDING MACHINE, CNC
MACHINING CENTER, and 3-D COORDINATE MEASURING MACHINE. Each compressor at HANBELL also
follows the ISO 9001 certification quality system which assures the best quality control and production process to
customers. RC2-F series compressor has 27 models RC2-100~RC2-1530, with displacement (50/60Hz) from 98
/ 1 18 m3/hr to 1539 / 1847 m3/hr.
The RC2-F series compressors use high quality bearings which resulted in longer bearing life compare to
competitors. These bearings provide strong support to screw rotors especially for the heavy duty application.
Oil/Refrigerant injection port can be utilized when external cooling is needed at chamber. This can keep the
compression chamber at proper discharge temperature and ensures sufficient oil viscosity for moving parts
lubrication. Economizer port can be used to reach higher cooling capacity and working efficiency especially at high
pressure ratio working condition or at very low evaporating temperature. All these new designs guarantee that the
compressor has the best reliability, longest bearing life and easiest regular maintenance work.
This Technical Manual contains all basic information about dimensions, handling, installation, operation, trouble
shooting, and system application. It is highly recommended that the content of this manual should be read carefully
prior to handling, installing, and operating the RC2-F compressor in order to prevent any unwanted damage on it.
For any technical issue related to RC2-F series compressor, please contact HANBELL or local distributors/agents
for more information and assistance.

1. Compressor’s characteristics
1-1 Multi country (Taiwan, China, USA, England) patented high efficiency 5 to 6 asymmetrical rotor profile.
1-2 Precise volume control system
Steps or continuous capacity control system are available.
1-3 Economizer applications
Economizer port is a standard accessory for RC2-F series screw compressor.
Floating type medium pressure (Economizer returned pressure) design, no matter if compressor work at full
load or partial load condition, always can track the best medium pressure value, it means economizer could
develop the maximum efficiency during the operation.
1-4 Applicable with:R-134a, R-407C, R22, R404A, R507A.
1-5 Resistant to high load condition with long life bearing design
1-6 PTC temperature thermistor for the protection of
(1) High motor coil temperature
(2) High discharge temperature
(3) High oil temperature (optional)
1-7 Low vibration and low noise.
1-8 High efficiency oil separator, low-pressure drop, external connection.
