Atlas Copco GHS 1402 VSD+ – 22 kW with IE5-equivalent motor

The GHS 1402 VSD+ delivers a nominal displacement of 1383 m³/h with an ultimate pressure of 0.3 mbar(a). Rated motor power 22 kW, frequency range 20–166 Hz (600–5000 rpm). Dimensions 1460 × 1360 × 1660 mm (L × W × H), net weight according to the data sheet 1080 kg, gas inlet and gas outlet DN 150 PN 10.

Drive

Atlas Copco uses a permanent-magnet-assisted synchronous reluctance motor with an efficiency equivalent to IE5, combined with the Neos Next inverter. The motor is cooled by the pump oil and needs no fan of its own; the drive train is protected to IP66.

Applications

As fields of application, Atlas Copco lists forming and shaping applications (vacuum-formed packaging, thermoformed plastic parts), preserving (central vacuum systems for food packaging machines, chamber and carousel packaging machines), humid applications (clay extrusion, pipeline drying, vacuum cooling), clean operating environments (house vacuum, the electronics industry, laminating) and holding, lifting, conveying and transport applications.

Variants of the GHS 1402 VSD+

The GHS 1402 VSD+ is listed in 9 variants. They differ in the following features:
  • Humid version for high air humidity: considerably higher water vapour tolerance, gas outlet DN 150
  • Version with energy recovery (ER): according to Atlas Copco around 80 % of the energy can be recovered as heat
  • Version for high ambient temperatures (HAT) up to 50 °C
  • Stainless steel version (SS)
  • Oil: synthetic oil or food-grade oil (Foodgrade); operation via 7" touch HMI
  • Versions with test report (Test Report)
All variants are designed for 3Ph 380-460 V 50/60 Hz. Not every size is available in every version; the list of variants is decisive.
