The decision to invest in a Helium Recovery system is often determined by its financial feasibility.Here is a sample calculation to assist in determining if the system can be justified.

• Application: Helium leak test of A/C components
• Internal volume of product: 100 in3
• Production rate: 500/hr
• Tracer gas test pressure: 200 psig

Model Selection
A variety of models are available, each designed to recover a particular volume of gas. Standard sizes include:

• 4 SCFM P/N 925-117
• 8 SCFM P/N 925-119
• 20 SCFM P/N 925-112

Performance Efficiency

• Approximately 98%.  Actual efficiency will be dependent on charge pressure, cycle time and product volume.

Compressors

• Systems utilize oil-less piston compressors designed for industrial gas compression applications.

Electronics

• Microprocessor-based programmable logic controller housed in NEMA 12 enclosure.  System includes diagnostics and operating parameter displays.

Valving

• Rack and pinion pneumatically actuated ball valves.

Pressure Vessels

• ASME coded tanks designed for 300 psig service.  Actual number and volume of tanks will be dependent upon gas handling volume.  All manifolding, valving and tanks are helium leak tested to 1 × 10^-6 atm cc/sec at 300 psig.

Heat Exchangers

• Four high efficiency tube and shell exchangers ensure adequate cooling of process gas.

Process Monitors

• A group of thermocouples and pressure transducers monitor temperature and pressure in critical areas.  System includes real time monitoring capability and process alarm display.

Gauging

• Tank pressures are displayed on operator control panel.  System includes high pressure regulators for output supply and make-up process gas.

Utility Requirement

• Power: 440 Volt / 60Hz / 3 Phase
• Power Consumption: Approx. 18,000 Watts
