The Haskel Q-Drive unit Industrial electric gas boosters promise quieter, cleaner, hassle-free operation GAS BOOSTERS GAME-CHANGING F
or many applications, industrial gases such as nitrogen, oxygen, argon, CO2
in steel cylinders at pressures of
2,000-2,600psi. If the gas is used below the supply pressure, the pressurised supply can be piped and controlled to the point of use with simple valving. However, if the gas needs to be a higher pressure than the supply, industrial gas boosters are used. Unfortunately, traditional pneumatic
and hydraulic gas boosters used for this purpose come with some inherent limitations. Pneumatic (air-powered) units work well to boost pressures at
and others are delivered
intermittent, low-flow rates, but are extremely noisy during operation. At higher flow rates the sound is further increased, since multiple units must fire in parallel. Tis also increases the amount of electricity required. Hydraulic-powered units, on the other hand, are more suited to continuous operation and are slightly quieter than pneumatic options, but come with the potential risk of hydraulic oil leaks and spills. Now, a new category of advanced electric gas boosters is promising to provide quieter, cleaner, high-pressure, high flow rates up to 6,500psi – along with improved monitoring and controls.
Tese units are ideal for the automotive, aerospace, oil/gas and industrial gas supply industries for high pressure gas boosting, gas transference, cylinder charging and scavenging. Tey also open new possibilities for the food/beverage, cosmetics and pharmaceutical industries that require a high-pressure, high flow rate gas for supercritical CO2 pressurised CO2
extraction. Tis uses to extract desired natural
substances such as fats, oils or enzymes. One burgeoning market for supercritical extraction is for cannabis extraction to produce industrial hash oils used in vaporiser pens, salves, edibles and elixirs.
