Leybold ECODRY 65 He plus – for helium recovery and closed circuits
The ECODRY 65 He plus is based on the ECODRY 65 plus and is optimised for permanent gases such as nitrogen, helium-3, helium-4, argon and neon – in certain set-ups also for SF₆. It achieves 55 m³/h for air and 52 m³/h for helium with an ultimate pressure below 0.03 mbar. Dimensions (623 × 320 × 298 mm), weight (around 43 kg) and flanges (DN 40 ISO-KF / DN 16 ISO-KF) are the same as on the ECODRY 65 plus.Tested leak-tightness
Leybold specifies a leak rate below 5 × 10⁻⁸ mbar·l/s, confirmed by an integral leak test; each pump is supplied with a certificate confirming that it passed the test. This version deliberately does without a gas ballast – it would be a potential leak point and a source of unwanted gas contamination.Typical applications
Helium recovery and recirculation in closed systems, cryostats, dilution refrigerators, leak detection and superconducting magnets.Variants of the ECODRY 65 He plus
The ECODRY 65 He plus is available from Ehrler & Beck in two variants (part numbers 161065V32, 161065V31). The rated power is 1.2 kW for all variants (0.6 kW at ultimate pressure); the mains voltage ranges from 100–120 V to 200–240 V (50/60 Hz, 1-phase). The weight is around 43 kg.Features of the ECODRY plus series
- Oil-free and clean: no oil, no particles, no dust in the pumping chamber; no odours
- Quiet: 52 dB(A) – below the level of a conversation
- Low maintenance: according to Leybold, up to five years without oil change or seal replacement
- Energy-efficient: 600 W power consumption at ultimate pressure, little waste heat
- Compact and mobile: small footprint, 1-phase mains connection
- Networkable: X104 interface (RS485) for monitoring and remote control
