HCS Series Screw Compressor Packages

HCS Series 2 HCS Series

Heart of the System HCS Series: • Single-stage dry screw compressor • 5 Frames available • Flow rates from 380 to 4700 CFM (650 to 7980 m 3/hr) • Pressures from 15 to 50 PSIG (1 to 3. 5 Bar. G) 3 HCS Series

Heart of the System Operating Principle: • Two meshing rotors positively displace air from inlet to outlet • As the air is forced between the asymmetrical profile of the rotors, it is compressed to approximately 15 PSIG (1 Bar. G) • The seal created between the rotors and casing allow back-pressure to build. . . up to 50 PSIG (3. 5 Bar. G) 4 HCS Series

Heart of the System Design Features: • Stainless Steel shaft seals on either side of the rotor keep air from leaking out of the compression chamber. • Timing Gears ensure NO CONTACT between the two rotors. • Rotors are coated with ULTRACOAT® – Provides corrosion resistance – Reduces fictional losses 5 HCS Series
