Tip: Counter-cooling your PRESTO with a Recirculating Cooler
If there is no cooling water, the PRESTO W92 can be cooled down with a recirculating cooler with a cooling capacity of 45 kW at a flow temperature of 15°C. The required circulating pump has to ensure a flow rate of 43 l/min at a counter-pressure of 0.5 bar. The recommended minimum tank volume is 200 liters.Characteristics
