E. J. BOWMAN (Birmingham) LTD WEB SITE - http://www.ejbowman.co.uk 10. DC Oil Coolers This page describes our DC range of oil coolers which are designed for use on small marine transmissions. They have the same cupro-nickel tubes as our larger EC to PK range of oil coolers and therefore have the same long life expectancy. The seawater connections are neoprene mouldings making them simple and easy to install and should cleaning be necessary, they can be removed using only a screwdriver. We can select by computer the appropriate oil cooler for a particular duty from the following information. oil type or its viscosity at a specified temperature heat to be dissipated oil flow oil inlet temperature seawater temperature seawater flow cSt at °C kW liter/min °C °C liter/min If this information is not available, a selection can be made using the table below. In many cases we will have on file information which will enable us to select a suitable oil cooler for a particular engine and gearbox combination. Two oil connection sizes are available and three seawater pipe sizes which can be either in line or at right angles to the axis of the cooler. If preferred, the oil coolers can be supplied without end covers for incorporating directly into the seawater pipework. 1 10. DC Oil Coolers Iss. 16-4-99
