Saving and recovery of liquified gases

Multiphase booster pumps were developed by Hydraulics International Inc. specially for handling different liquified gases such as freons, halogens, CO₂, LNG etc.

Multiphase boosters HII are designed for handling fluid in any phase from 100% gas phase to 100% liquid phase.

HII multiphase pumps basic line is represented with 5 models for solving standard tasks of liquified gases handling. This basic line can be supplemented with liquid pumps line and gas boosters line to handle any special engineering task.

Freons, freons and other liquefiable gases supply units are HII ideal for the tasks of pumping the gas phase to zero, filling refrigeration equipment, fire extinguishing modules, saving expensive refrigerants.

The plants save considerable money by saving expensive gases. The payback period of the plant as a result of direct savings can be several weeks or even several days, depending on the price of the pumped gas.

Multi-phase liquefied gas units are designed to transfer the medium in any phase from 100% gas to 100% liquid.

Can be used to pump out-of-circulation chladones, problematic gases such as carbon dioxide, hazardous, reactive media.
