Top performance, even when charging!

The OPEN model meets professional needs that require large charging capacities in hot, poorly ventilated environments or tropical countries. It has 4 front filling connections for high pressure hoses, an intuitive control panel and an electric motor. The pumping group, chosen from the 4 most powerful, is exposed in the rear housing to ensure a better cooling cycle. For longer filter life, we recommend the Tornado high pressure dryer. Available option: Presec system for filter saturation control or the SAM system for multigas analysis and remote charging panel.

Open frame with vertical development designed to facilitate maintenance operations. The oil level and drain reported outside, the control console equipped with inter-stage pressure gauges, the oil pressure gauge, the internal temperature indicator, the presence alarm and incorrect phase sequence, the lack alarm oil and the start, stop and manual condensate drain commands allow easy management and maintenance of the compressor.
