HG10 and HGF10 Series

Models HG10000 and HGF10000 Non-Geared

BENEFITS

Rotary Screw Compressors are very cost-effective for handling high volumes of gas in field gathering, vapor recovery, and other applications. The HG10 and HGF10 Series are suitable for applications to 90 BHP and 350 PSIG discharge pressure.

 

Low maintenance and high reliability are inherent with rotary screws because they have few moving parts. There are no valves, rings or packing to wear out or cause loss of efficiency.

 

Smooth operation results from no unbalanced forces and no pressure pulsation. No foundation is required and there are no piping vibrations from pressure pulsation.

 

Natural gas engine or electric motor drives are equally acceptable
with rotary screws.

 

LeROI Rotary Screw Gas Compressors are available in 13 models
covering a flow range of 20 to 15,000 MSCFD and horsepower
from 10 to 800.

 

FEATURES

The HG10 can be belt driven or direct coupled to electric motors for maximum flexibility at minimum cost. The compressor shaft bearings can absorb the belt side load without additional pillow block bearing supports up to 30 HP. The HGF10000 is suitable for direct coupling to engines and electric motors.

 

Single-Stage operation from 20 PSIG inlet to 350 PSIG maximum is possible with the HG10 and HGF10 Series oil-flooded compressors. Compressor packages are therefore simple, reliable and inexpensive.

 

The gas differential pressure provides oil circulation for proper lubrication at differential pressures over 70 PSI. An auxiliary oil pump is required on applications below 70 PSI differential pressure.

 

Discharge porting can be selected to match the internal compression to the application requirement for maximum compression efficiency.

 

All iron or steel construction with no copper or copper alloys
makes these compressors compatible with natural gas, sweet
or sour.
