COOLPAK e – Helium Compressors

Leybold’s new COOLPAK e compressors are synonym for innovation, intelligence and energy savings.

COOLPAK e – Innovation and intelligence

Oil lubricated scroll technology and a variable speed drive offer excellence in system performance, energy demand and work space environment. With highly efficient separation and filtration systems the COOLPAK e generates continuous helium gas flow of high purity to the cryogenic systems.

The water cooled helium compressor is controlled and maintained by an internal controller: the Atlas Copco Elektronikon used in several thousand of industrial air compressors. The system offers superior performance for your cryogenic refrigerators and pumps for a wide range of applications.


Innovative scroll technology ■ Highly efficient hermetical scroll compressor ■ Motor speed control ■ Outstanding performance with high helium gas flow ■ Robust design Improved workspace ■ Very efficient oil retention system ■ Compact design ■ Small footprint ■ “Plug and play” system Guaranteed oil retention ■ Optimum filter design for maximum oil retention ■ Design ensures that the oil separators are never overloaded which extends the filter cartridge life-time ■ The innovative oil restraint system minimizes the discharge of oil mist into the helium system Integrated frequency converter & controller ■ Frequency converter for industrial use ■ Variable motor speed of the scroll compressor ■ Variable motor speed control of the refrigerator drive unit ■ Minimal components: compact, simple and user-friendly Energy saving options & Cost of Ownership ■ Energy savings due to variable motor speed of compressor and cold head ■ Up to 25% power input saving by using the ECO mode ■ Programmable operation modes ■ Adaptable power demand ■ Elongated maintenance period ■ Highly efficient filtration system Easy to use ■ The “plug & play” system design supports quickest installation and start-up without complicated programming ■ Easy serviceability (adsorber exchange) ■ Maintenance interval of up to 30,000 h Helium compressor COOLPAK 2000e An additional high quality product to fulfill your requirements. Especially developed for all applications with our COOLPOWER 7/25e, 25e and 50e as well as for our COOLVAC e series between 1500 and 3000 l/s. Air-cooled variant COOLPAK 2000e For environments where water cooling is not available or cannot be used, we have developed an air-cooled variant of the COOLPAK 2000e with similar functionality as the water-cooled variant. Running with the COOLPOWER 7/25e, 25e, and 50e, as well as the cryopumps COOLVAC 1500 eSL up to 3000eSL, the air-cooled variant can be operated in harsh work environments.
