GAS BOOSTERS

The MAXIMATOR high pressure boosters are suitable for the oil free compression of gases and air. Industrial gases like argon, helium, hydrogen and nitrogen can be compressed to operating pressures of 2,100 bar (30,000 psi) and oxygen to 350 bar (5,075 psi).

The MAXIMATOR high pressure boosters are suitable for the oil free compression of gases and air. Industrial gases like argon, helium, hydrogen and nitrogen can be compressed to operating pressures of 2.400 bar (36.000 psi), oxygen to 350 bar (5.075 psi).
Air driven boosters are an efficient alternative instead of electrically driven products and can be used in explosion-proof areas (according to 2014/34/EU)

The Maximator gas boosters’ operating principle is similar to a pressure intensifier. A large air piston is charged with low pressure (air piston) and works on a small area with high pressure (high pressure piston).

The continuous operation is achieved by a pilot operated 4/2 way valve (spool valve). The spool valve applies the drive air alternately to the upper and bottom surface of the air piston.

The spool is piloted through two 2/2 way valves (pilot valves) which are mechanically actuated through the air piston in its end positions. The pilot valves charge and discharge the spool chamber.

The high pressure piston supported by the check valves (inlet check valve and outlet check valve) delivers the flow.

The outlet pressure is directly related to the set air drive pressure. According to the formulas indicated in the technical features table for the gas boosters, the static end pressure can be calculated.

At this pressure a force balance between drive section and gas section is achieved. The booster stalls when this end pressure is reached, and does not consume any further air.

A pressure drop at the high pressure side or a pressure increase at the drive side starts the booster automatically until the force balance is achieved again.

Additionally the Maximator boosters can be switched on and off automatically through Maximator air pilot switches, contact gauges or external control devices.

As a result of the wide range of models it is possible to select the optimum booster for each application. Single stage, double acting or two stage boosters or a combination of these models can be used to achieve different operating pressures and flow capacities.
