LASER - compressed air stations for laser cutting machines
For laser cutting
Complete compressed air station for laser cutting machines: compressor, high-pressure dryer and receiver in one system - no external booster required. Operating pressures 14,5 / 16 / 20 bar, power ratings 11-37 kW. Available as FRECON PLUS PM LASER with variable-speed drive (VSD) and fixed-speed HSC LASER.

IMPETUS - two-stage screw compressors
Featured range
The two-stage screw airend achieves higher isentropic efficiency than single-stage designs, reducing specific energy consumption per cubic metre of air produced. Power range 90-315 kW, VSD versions available. PID pressure control maintains pressure within a narrow band and limits unloaded running, directly reducing energy consumption.

HSC screw compressors
Single-stage, fixed-speed screw compressors designed for continuous operation with relatively stable air demand. Operating pressure range 7,5-13 bar, depending on model. The simple drive system means fewer failure-prone components and low maintenance costs.

FRECON PLUS
Variable-speed screw compressors with power ratings of 90-315 kW and operating pressures of 7,5 / 10 / 13 bar. The compact FRECON PLUS PM version covers power ratings up to 75 kW and uses IE5 IPM permanent-magnet motors with a SmartDrive inverter, which adjusts airend speed to current air demand. Eliminating unloaded running and unloading cycles delivers energy savings of up to 55% under variable demand compared with fixed-speed compressors.

EAGLE - oil-free
Completely oil-free compression - the air meets Class 0 under ISO 8573-1, the highest oil-content purity class in this standard. Operating pressures 7,5-10 bar, depending on model. A solution for packaging, electronics and pharmaceutical applications where air comes into contact with the product.

HS scroll compressors
Oil-free scroll compressors delivering Class 0 air under ISO 8573-1. Low rotational speed and few moving parts ensure quiet operation, low vibration and long service life. Their compact design allows installation close to air consumption points.

PET MASTER - compressors for PET bottle blow moulding
Oil-free high-pressure compressors dedicated to PET bottle blow-moulding lines, where air comes into direct contact with the packaging. Designed for continuous operation at the high operating pressure of the blow-moulding system. Full power and FAD capacity ranges from the datasheet are available on enquiry.

HRD dryers and filtration
Refrigerated dryers maintaining a pressure dew point of +3 °C. Models up to HRD 210 have integrated inlet and outlet filtration: particle separation down to 0,01 microns and oil content down to 0,01 mg/m³. We select them together with condensate drainage as a complete air treatment system downstream of the compressor.

HDA adsorption dryers
Heatless, cold-regenerated adsorption dryers with a standard pressure dew point of −40 °C, optionally −70 °C. Nominal capacities are specified at 7 bar; high-pressure versions for 16 and 40 bar are also available. Used in moisture-sensitive systems: outdoor sections exposed to frost, pharmaceutical and electronics applications, and measurement processes.

What we provide as a distributor
Power sizing for your facility
We analyse actual demand and operating patterns rather than selling an oversized machine just in case.
Delivery and commissioning included
Transport, installation and initial start-up are included in our offer.
Genuine Hertz parts
Manufacturer's filters, oils and service kits - no improvisation during maintenance.
24/7 service
Warranty and post-warranty servicing with a fast response to breakdowns.
Replacement compressor during repairs
If repairs take longer, we provide a replacement compressor to keep production running.
Available on enquiry
Heat-regenerated adsorption dryers
Regenerating the desiccant with a heater reduces purge air losses, which matters at high flow rates. We select the equipment after establishing flow, pressure and the required dew point.
High-pressure boosters
They raise pressure from the existing compressed air network to the level required by a specific process. We select the range to suit inlet pressure and required capacity.
Hertz gas generators
A generator can be added to a Hertz compressor to produce nitrogen or oxygen from compressed air.
Hertz HNG nitrogen generators
They use PSA technology with CMS carbon molecular sieves, producing nitrogen with a purity of 95 to 99,999 percent.
Nitrogen generators
Hertz HOX and HO2 oxygen generators
They use PSA technology with zeolite molecular sieves, producing oxygen with a purity of 90, 93 or 95 percent. For technical oxygen only.
Oxygen generators
Hertz Kompressoren compressors - suitable industries
Hertz Kompressoren offers oil-injected and oil-free screw compressors for manufacturing plants, industrial workshops, plastics processing, the food industry and laser cutting businesses. As a distributor, we select Hertz compressors to match actual requirements: operating pressure, flow, daily operating profile and air purity class. We recommend variable-speed machines for fluctuating loads, fixed-speed machines for continuous operation, and oil-free ranges for oil-sensitive processes.
Hertz compressors and the complete compressed air station
The compressor is only part of the system. We select the complete station - compressor, receiver, dryer and filtration - as part of our compressor sales, and complement air treatment with dryer servicing for refrigerated and adsorption dryers, including Hertz HRD and HDA and BEKO Technologies DRYPOINT. If you are unsure what power rating you need, start with a compressed air audit - measurements reveal actual air demand and inform machine selection.
Hertz compressor servicing
We carry out maintenance and repairs using the manufacturer's genuine parts and oils, at the intervals specified in the machine's operating and maintenance documentation. We also service other brands - the scope of work is described on our page for screw compressor servicing. For longer repairs, we provide a replacement machine to keep production running.
