    PET MASTER SERIES

    PET MASTER SERIES


     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
