Haskel Gas Boosters consist of a large area reciprocating air drive piston directly coupled by a connecting rod to a small area gas piston. The gas piston operates in a high pressure gas barrel section. Each gas barrel end cap contains high pressure inlet and outlet check valves. Varying applications require many different booster and horse power (HP) combinations. Haskel can assist with HP and Cooling requirements and provide circuitry assistance on the following issues: PID Control – review and advisement, electrical control, and heat exchanger recommendations. General HPU recommendations and guidelines are available from Haskel drawing 87100-TAB. The air drive section includes a cycling spool and pilot valves that provide continuous reciprocating action when air is supplied to the air drive inlet. The ratio between the area of the air drive piston and the gas driven piston is indicated by the number in the model description and approximates the maximum pressure the gas booster is capable of generating.
Isolation of the gas compression chambers from the air drive section is provided by three sets of dynamic seals. The intervening two chambers are vented to atmosphere. This design prevents air drive contamination from entering the gas stream.
Cooling is provided by routing the cold exhausted drive air through an individual jacket surrounding the gas barrel.
Check valves also allow for the equalisation of upstream and downstream pressure prior to boosting, therefore the gas booster only needs to “raise” the upstream pressure to the required pressure and does not have to raise it from atmospheric pressure.
