State-of-the-art Gas Pressure Boosting Technology

Boost Your Industrial Processes

Our PRESUS^® gas pressure boosting solutions for N₂and CO₂ are a cost-effective, energy-efficient alternative to conventional compressors for countless applications from injection molding to cryogenic cleaning

Success Under Pressure with PRESUS

Many industrial applications rely on a steady supply of high-pressure carbon dioxide (CO₂) or nitrogen (N₂). Typical examples include plastic foaming, gas (assisted) injection molding, hot-spot cooling of injection molds, laser-beam cutting, cryogenic cleaning and cooling during thermal spraying.

We developed our PRESUS^® family of pressure boosting devices to deliver CO₂, N₂ or even argon (Ar) to these and similar applications. These modern, cost-effective and energy-efficient units are delivered as part of an all-inclusive solution spanning the gas bulk tank, the PRESUS high-pressure boosting pump, high pressure vaporizer, a high-pressure pipeline as well as a high-pressure temperature control solution to keep the gas well within the defined limits at the point of use.

The PRESUS^® C unit is suited to applications that run on CO₂ whereas PRESUS^® N is tailored to use cases that require N₂ or Ar. Both are available with models to suit individual pressure, volume, mass flow and footprint requirements. Click below for more details.

Gas Pressure Booster Family

PRESUS C

Designed for the highest standards of quality and reliability, PRESUS C supplies carbon dioxide at a high mass flow and constant pressure in a virtually bubble-free state to a variety of industrial processes. Redundant pumps and pneumatic operation make these boosters extremely reliable. During service or maintenance windows, the CO₂ is supplied from the backup unit to ensure process continuity. Operators can switch between the main and backup units automatically by means of a PLC. The PRESUS C configuration offers cost efficiency gains over ring pipe solutions and dual tank (low and high pressure) setups. Different family members support different pressure ratings, scaling up to a working pressure of 130 bar and a mass flow of up to 500 kg/hr. A special high-pressure PRESUS C unit supporting a working pressure of up to 400 bar is also available for specific applications such as gas injection molding with PLASTINUM^® GIM C.

Highlights of PRESUS C

Reliable and continuous supply of CO₂ at high pressure
Avoidance of bubbles that can otherwise occur in the CO₂ and compromise production and cause increased downtimes and scrap rates
Lower energy consumption due to pneumatic (pressure-triggered) drive concept and idle mode, making PRESUS C ideal for intermittent operations
More convenience and flexibility as mass flow adapts automatically to changes in counter-pressure

PRESUS N

PRESUS N uses a hydraulically operated, slow-moving piston to pressurize liquid nitrogen or argon to anywhere up to 340 bar depending on application requirements. Supporting N₂ flow rates from 5 – 130 m³/h, PRESUS delivers oil-free N₂ in the purity grade specified and vaporized. Requiring only a small footprint compared with state-of-the-art gas compression units for the same capacity and pressure, it comes with a small gas buffer and is installed outdoors.

Highlights of PRESUS N

Low energy consumption - up to 90% lower than that required by state-of-the-art gas compression units
Flow rate at least five times higher than that of state-of-the-art gas compressors
Oil-free operation, thus avoiding the gas purity degradation associated with gas compressors
Ease of operation with automatic PLC control system
