WATER OIL COOLEROiltech PWO with cooling capacity 1-480 kW

Oiltech offers a complete range of water oil coolers for cooling oils.The PWO series includes water oil coolers especiallysuitable for use in lubricating and hydraulic applications.

PWO water oil cooler is ideal for use in stationary lubricatingsystems and hydraulic applications as a minimum of space isrequired and the heat transfer capacity is very high. Theeconomical PWO water oil cooler can easily be oversized forany future increase in cooling requirements or peak loads.

WATER OIL COOLER OPERATIONPWO provides an oil temperature very close to the coolingwater temperature, eliminating the need for an active coolingsystem in certain applications.The unique PWO design features result in a turbulent oil andcooling water flow, the key to high cooling capacity. This

turbulent flow prevents clogging, a frequent cause of reducedheat transfer efficiency. The PWO cooler provides reliabletemperature control of oils, a condition for maximum per-formance.

BENEFITS• Low water consumption – economical in operation• Turbulent flow – prevents clogging – reduced maintenance• Compact – small installation dimensions – easy assembly• Broad range – excellent technology – innovative solutions• Standard range – always on stock – delivery at short notice

Steel and metal industryFrom heat to cold steel.An immense quantity of thermal energy is required to transformiron ore to casting pigs, sheet metal and tubes.A great deal of this heat is transformedinto gas or vapour. Besides, heat is absorbed by the walls of the blast furnace, pressesand moulds as well as by the tempered oil, quench water, lubricants and other fluids,which all require cooling.

Similar conditions prevail whenmaking aluminium, copper andmany more metals. Oiltech's high-quality water oil cooler providesfast and high-efficient cooling. Ourexpertise can show you how tore-use this energy, saving moneyfor you at the same time as meet-ing your requirements.
