An all in one solution designed to supply fresh water to divers living in hyperbaric chambers. The water is supplied at 5 bar above diving depth pressure through either one of the unit's two automatic triplex pumps. The unit features a 10” 20 micron filter that filters out solid particles from the incoming water and two 72 litre geysers, each with a 6kW heating element that enables the supply of hot water to the occupants of the hyperbaric chambers. The automatic pumps fitted to the unit are controlled by means of variable frequency drives using pressure transducers on the delivery lines and a digital controller.
