Pandaflo pressurisation units are designed to replace water that has been lost through system leakage and to maintain the system design fill pressure in sealed heating and chilled water systems. Our units also provide safety circuits locking out the boiler / chiller in the advent of high / low pressures occurring. Expanded water is accommodated in membrane vessels that are supplied separately and normally installed alongside the unit. We can offer pressure switch and electronic control as well as open and cabinet enclosed options.
