Reciprocating piston compressor Ace VI HE Zero Loss

pistonreciprocatinghelium

Overview
ACE VI HE Zero Loss is a 4-stage helium-line gas compressor with integrated gas recovery and purification, designed for low-noise operation and zero-loss recovery of technical gases. It couples an aluminum monoblock pumping unit with advanced condensate management and an activated-carbon Hyperfilter to ensure reliable compression and treatment of technical gases.

Main features

• 4-stage pumping unit with dedicated gas recovery on the first stage
• Aluminum monoblock construction
• Forced lubrication via low-pressure gear pump
• Pipes, fittings and nuts in AISI 316 stainless steel
• Intermediate condensate separators after the 2nd and 3rd stages
• High-pressure final condensate separator
• Safety valves after each compression stage
• Special cast-iron cylinders with low-roughness lapping
• Forged aluminum connecting rods and forged steel crankshaft
• High-flow fill valves on stages 1–3
• Heavy-duty roller bearings
• Hardened steel 4th stage with six special cast-iron piston rings
• Thrust pads on 2nd and 3rd stages to eliminate lateral piston forces
• Activated carbon Hyperfilter purification system

Electric motor
The unit is driven by a three-phase electric motor; available power for this model ranges from 11 to 15 kW.

Purification system
The Hyperfilter purification system is installed after the final compressor separator and before the pressure maintenance valve to treat technical gases reliably. Filtering capacity (inlet air at 20°C and 200 bar): 52,500 m³.

Electrical cabinet

• ON/OFF switch with motor protection
• Electromechanical pressure switch to stop the compressor at final pressure
• Drainage of all interstage separators and of the final separator during operation
• Timer for automatic condensate drainage device
• Integrated no-load startup (automatic discharge at each shutdown)
• Condensate collection tank: 5 L silenced tank, approx. 3 L usable capacity for environmentally compliant disposal
• Interstage pressure gauges to display operating pressure per stage

Frame and chassis
Silenced cabin chassis with vertical layout for low-noise environments. External oil level indicator and drain. Control console with interstage gauges, oil pressure gauge, internal temperature indicator, phase-sequence and oil shortage alarms, run/stop and manual condensate drain controls. Steel frame with scratch-resistant powder coating in Black RAL 9005.

Standard equipment

• Dual PED-certified Hyperfilter system
• Condensate separation system
• Frame color Black RAL 9005
• Compressor control and automatic condensate drainage system
• Electronic pressure switch
• Interstage control manometers
• Soundproof cabinet with absorber
