The OPEN model was created to satisfy the professional needs of those who use it intensively and requires large charging capacities, in hot, poorly ventilated or tropical environments. It is equipped with 4 front filling connections for high pressure hoses (from 232 to 420 bar), a control panel and electrical switchboard. The pumping unit exposed in the rear part of the frame guarantees a better cooling cycle. The OPEN HD 550 ET motor is a three-phase electrical unit coupled with the more powerful Coltri pumping units.
