Good day, dear readers, and welcome to our blog. On this occasion, the Maxipresstec team will talk about one of the products in its catalog, the high pressure Maximator gas booster. Maybe this device is new to you, or maybe you are already familiar with it, but in any case, read on to know more about this type of booster, its characteristics, its classifications and its applications. So let’s begin.

Maximator gas boosters are ideal for compressing gases and air. Industrial gases such as Argon, Helium, Hydrogen and Nitrogen, etc., as well as their mixtures, can be compressed at operating pressures up to 2400 bar (36,000 psi) and oxygen up to 350 bar (5075 psi). When boosted by air, boosters are an efficient alternative, ideal for use in areas with risk of explosion.

Now let’s talk about how the Maximator gas booster works and what the operating principle of this device is:

To begin with, a large air piston is charged with low pressure and works over a small area with high pressure. The continuous operation is achieved by a valve 4/2 operated by pilot (spool). Then, the spool directs the air piston alternately on the surface and the bottom of the piston on the high pressure side by an increase in pneumatic pressure.

The spool is piloted through a 2/2 valve, which are actuated mechanically through the final positions of the air piston. This way, the pilot valve loads and unloads 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 present air pressure. For this outlet pressure to occur there is a balance of forces between the air section and the high pressure gas section, so that the booster stops when the desired pressure is reached, and it no longer consumes more air.

Thus, a pressure drop on the high pressure side or an increase in the air pressure of the spool will start the booster automatically, until the balance of forces is reached again.
Additionally, Maximator boosters can be controlled automatically by an On / Off Maximator pressure switch, contact pressure gauges or external control devices.

After this brief introduction to its operation, it should be mentioned that the gas boosters can be classified as follows, depending on the pressure they handle:

  • Boosters for 40 bar (580 psi)
  • Boosters for 100 bar (1450 psi)
  • Boosters for 600 bar (8700 psi)
  • Boosters for 1500 bar (21750 psi)
  • Boosters for 2400 bar (36000 psi)

As a result of the wide range of models that currently exist in our product portfolio, it is possible to select the optimal booster for each application. For example, the boosters can be single-stage, double-acting, two-stage or a combination of these examples, in order to achieve different operating pressures and flow capacities.

As part of our services and to meet the needs of our customers, we can also design and manufacture booster stations with capacities up to 2400 bar, with instrumentation included, according to the specifications required by each user’s work.

Now, gas booster stations can be for nitrogen or for a wide variety of gases, so regardless of the model or gas, these stations are always ready to connect and can be used for all kinds of tests, recovery of gases or for other high pressure applications.

Once the station has been acquired, it will be connected to a compressed air line, since an electrical connection is not required to generate the pressure. For simple applications, the gas booster stations will be equipped with all the necessary components. Part of them is a combined air control unit with filter and water separator, a pressure regulator, a pressure gauge, as well as a manual shut-off valve to stop the pressure in the air drive.

On the high pressure side, the booster gas station will be equipped with a pressure relief valve, and one or more outputs to connect the test specimens.

To indicate and monitor the outlet pressure, high pressure manometers or electronic means for monitoring and pressure control can be used.

Finally, we will mention some applications that can be given to this type of boosters, which are:

  • Gas pressure tests
  • Gas transfer
  • Gas recovery
  • Loading of nitrogen accumulators
  • Supply of gas insulation systems
  • Assisted plastic injection (GAIM)
  • CO2 foam
  • Transfer to oxygen cylinders
  • Loading of breathable air bottles
  • Diving
  • Leak tests
  • Cleaning of burners
  • Inert atmosphere
  • Air bag systems
  • Stamping

As you may have noticed, Maximator gas boosters are very versatile, and their applications are very varied.
