The F-50 comes in two primary variants: the (low voltage) and the F-50H (high voltage). Specification Cooling Method Water-cooled Electrical Supply (F-50L) 3 Phase 200 V, 50/60 Hz Electrical Supply (F-50H) 3 Phase 380-415 V (50 Hz) / 460-480 V (60 Hz) Power Consumption 6.5–7.2 kW (50 Hz) / 7.5–8.3 kW (60 Hz) Helium Pressure (Static) ~1.60–1.65 MPa at 20°C (varies by model) Helium Pressure (Operating) High side: 1.90–2.20 MPa; Low side: 0.40–0.60 MPa Dimensions (HxWxD) 591 x 450 x 585 mm (23.3 x 17.7 x 19.1 in) Weight ~120 kg (264 lbs) Installation & Environmental Requirements The unit should never be tilted more than
Low-pressure helium returns from the cold head through a return connector. Do not use demineralized water for cooling
An adsorber (active charcoal) removes remaining oil vapors before the pure helium is sent back to the cold head. Maintenance and Servicing
Requires a flow rate of 7–10 L/min (1.8–2.6 gal./min) at an inlet temperature of 4–28°C. Do not use demineralized water for cooling.
Operates best between 5°C and 35°C (41–95°F). Capacity may degrade by 5% if temperatures exceed 28°C.
