2.1Installation Guidelines

2.1.1Required Component—Inlet Gas Scrubber

An appropriate inlet gas scrubber is REQUIRED to remove liquids from the gas prior to compression. If there is potential for liquid slugging, a suitable trap must be installed to prevent liquid from flooding and damaging the Compressor.

NOTE

Failing to use an appropriate inlet gas scrubber to remove liquids from the gas prior to compression can cause flooding and damage the Compressor.

2.1.2General Installation Guidelines

Follow these general guidelines for installation:

The Compressor Module must be installed and operated in compliance with all applicable codes and regulations.

The system must be installed on a level surface.

Install pipe unions or flanges to connect the system to the inlet and discharge piping for ease of service.

Install isolation valves on the inlet and discharge piping.

A common ground must be connected between the Compressor Module and the

Compressor Package chassis. This ground must comply with the National Electric Code (NEC) and any other applicable codes.

Solid debris also must be removed from the gas prior to compression. When required, use a 5 to 10- micron inlet filter to remove debris from the gas stream. The degree of filtration required depends on the specific application.

2.2Inlet and Discharge Pressures

Refer to Table 1 for acceptable inlet and discharge pressure levels.

Minimum Inlet

0.75 psig

Consult the factory for operations below 0.75 psig.

Pressure

 

 

 

 

Maximum Inlet

 

Operation at pressures above 25 psig will result in:

25 psig

• Excessive oil carryover

Pressure

 

 

 

• Loss of oil from the Compressor Module

 

 

 

 

 

 

When the discharge pressure of the Compressor Module reaches the maximum,

 

 

 

which ranges from 70 to 190 psig, depending on the model (see Compressor

 

 

70 psig

Module Nomenclature on page iv):

Discharge

 

• The Compressor Module goes into high discharge pressure recycle if

 

to

 

equipped.

Pressure

 

190 psig

 

• The Compressor Module’s bypass regulator diverts gas from the high-pressure

Range

 

(depends

 

side to the low-pressure side of the module.

 

 

on model)

 

 

All Compressor Modules must be equipped with pressure-limiting or relief

 

 

 

 

 

 

devices. A minimum pressure differential of 70 psi between inlet and discharge

 

 

 

pressure is required for proper operation.
