37-220 kW   16-40 bar  3,6-23 m³/min


Oil-Free, Water Cooled, Fixed/Variable Speed

Reciprocating Air Compressors

We provide reliable and high-performance air solutions for the PET bottling, food and beverage industries requiring high compression.

 Advantages 

Compact structure, easy to install and assemble.

Takes up less room than other products in its class, providing maximum oil-free air capacity in minimum space.

Wear due to friction is minimized. This positively affects maintenance times and costs.

Stainless water separator increases corrosion resistance.

Soft start prolongs component life.


 General Features 

Reciprocating compressor providing 100% oil-free industrial air

Electric motor protection to prevent overload

Water-cooled design for high energy efficiency and ability to work in severe conditions

Energy-saving Load/Unload System for efficient operation

Integrated electrical system for user-friendly operation

20-40 bar operating range

 Electric Motor

 IE3 efficiency-class electric motors

 Special loadless start system and automatic discharge system for loadless start

 Long life with low RPM thanks to 6 pole feature


 Compressor Block

 Water jacketed cast iron cylinders and bottom heads

 Specially designed high-speed stainless steel concentric valves

 High-strength cast iron oil sumps

 Dynamically balanced high-strength forged steel crankshaft and cast iron

 Special aluminium alloy pistons and forged steel connecting rods


  Cooling System

The intercoolers and aftercoolers use stainless steel pipes for more efficient heat transfer and better corrosion resistance.

The coolers are designed to pass air through the pipe and water through the body wall.

The compact design of the pipe-type coolers ensures easy maintenance and very efficient cooling

 Electronic Control

Advanced, high-definition, user-friendly 7” colour touchscreen display (HMI)

High speed, robustly built industrial type PLC infrastructure

Encrypted Access Protection system with various levels of authorization

Display of relevant data on the screen clearly, trend graph recording and active monitoring

Alarm History records last 100 alarms

Ethernet / ModBus communication as standard

Flexible programmable / expandable Input / Output structure
