Low-noise, belt-driven oil-free scroll units for food, beverage, chemical and pharmaceutical work.
Scroll elements compress without oil, so the air leaves the unit oil-free.
Ask for an HS quoteHertz makes every stage of a compressed air system, so the compressor, the receiver, the dryer and the filters come from one range and one quote.

Screw, scroll, piston or turbo, oil-free or oil-injected.

HAR receivers from 100 to 10,000 L steady the network.

Refrigerated to +3 °C, desiccant to -40 °C or -70 °C.

Particles, water and oil out, down to 0.003 ppm oil aerosol.

Nitrogen from your own air, and chilled process water.
Compressed air can be one of the most expensive forms of energy in a plant, and the real cost of making it is often unknown. These are the figures Hertz publishes, and what the range does about them.
of the energy used to make compressed air ever reaches the point of use. The rest is lost as heat.
of a compressor’s total energy use can be recovered as heat, for hot water or for heating a room.
of industrial compressed air systems could see significant energy savings through low-cost improvements.

Hertz Kompressoren was founded in Germany in 2005 to build air compressors to a high level of German engineering. Today it makes air and gas compressors and the equipment around them, and exports to more than 130 countries.
Every new product goes through Hertz R&D performance tests under severe conditions, plus acoustic, thermal, longevity, electrical and functional tests, before it reaches production.
Variable speed compressors match the air they produce to demand, in real time. With heat recovery, Hertz states that up to 80% of the energy the compressor uses can be recovered.

When the air must not carry oil, as in the food, beverage and pharmaceutical industries. The Hertz range has oil-free rotary screw (EAGLE), scroll (HS), reciprocating (PET Master) and turbo compressors.
Hertz refrigerated dryers, such as the HRD, give a +3 °C dew point. Desiccant (adsorption) dryers, such as the HDA, HHD and HMD, reach -40 °C, or -70 °C as an option, for uses that need drier air.
It produces nitrogen from compressed air by pressure swing adsorption (PSA) on a carbon molecular sieve. Hertz HNG, HNIT and HNG MOD generators deliver 95% to 99.999% purity, and the HCX and HDX purifiers take it further.
