Gas compressor unit Ace III HE Zero Loss

pistonbelt-drivenstationary

Overview
The Ace III HE Zero Loss is a 3-stage helium-line compressor designed for industrial gas compression with Zero Loss gas recovery. It integrates advanced filtration, condensate separation and components sized for continuous, intensive operation.

Main features

• 3-stage pumping unit with gas recovery (Zero Loss)
• Aluminum monoblock construction
• Forced lubrication via low-pressure gear pump
• Safety valves after each compression stage
• Pipes, fittings and nuts in AISI 316 stainless steel
• Condensate separators after the medium-pressure and final high-pressure stages
• Die-cast aluminum cylinders with high heat dissipation and nicasil barrel coating
• Forged aluminum connecting rods and forged steel crankshaft
• Stainless steel valves on 2nd and 3rd stages
• Hardened steel third stage with 5 special cast-iron segments
• Roller bearings and thrust pads on 2nd/3rd stages for intensive use and reduced lateral piston forces
• Hyperfilter activated-carbon filter element for gas purification

Standard equipment

• Dual PED-certified Hyperfilter filter system
• Condensate separation system
• Silenced cab chassis, frame color Black RAL 9005
• Compressor control with automatic condensate drainage
• Electronic pressure switch and interstage control manometers

Electric motor
Three-phase electric motor transmits motion to the pumping unit via belt drive. Motor power available on this model: 4 to 7.5 kW.

Hyperfilter / Maxifilter purification system
The Hyperfilter/Maxifilter system provides reliable treatment of technical gases. Installed after the final separator and before the pressure maintenance valve, with separators after the 2nd and 3rd stages as primary moisture barriers. Filtering capacity (inlet air 20°C, 200 bar): 52,500 m³.

Electrical cabinet

• ON/OFF switch with motor protection
• Electromechanical/electronic pressure switch to stop compressor at final pressure
• Drainage of all interstage separators and final separator during operation
• Timer for automatic condensate drainage
• Integrated no-load startup (automatic discharge at shutdown)
• Condensate collection tank 5 L (usable approx. 3 L) with silencer
• Interstage pressure gauges for stage-by-stage monitoring and valve tightness checks

Frame and maintenance features
Silenced cab chassis designed for easy maintenance. Tilting motor carrier plate for constant V-belt tension, external oil level and drain, control console with interstage gauges, internal temperature indicator, phase-sequence and oil shortage alarms, run/stop and manual condensate drain controls. Steel frame with scratch-resistant Black RAL 9005 powder coating.
