DC Oil Coolers
This leaflet 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.
There seawater connections are neoprene moldings making them simple and easy to install and should be cleaning be necessary, they can be removed using only screwdriver. We can select buy computer the appropriate oil cooler for particular duty from the following information.
| oil type or its viscosity at a specified temperature | cSt at ºC |
|---|---|
| heat to be dissipated | kW |
| oil flow | liter/min |
| oil inlet temperature | ºC |
| seawater temperature | ºC |
| seawater flow | liter/min |
If this information is not available, a selection can be made using the table on the opposite page. 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.
Four 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 sea water pipework
Typical examples of oil coolers fitted to marine transmissions with an oil inlet temperature of 80ºC and a seawater temperature of 32ºC.

We have been making heat exchangers for over 75 years for a wide variety of application. Initially they were mostly for the automotive industry although now heat exchangers for marine engines predominate. Experience gained in the ardous marine environment has enabled us to build exceptionally reliable oil coolers for minig equipment and other areas where reliability is important.
The Company occupies a purpose built factory in a central location from which it directly exports over 50% of its production. Experience has shown us the there is rarely any need for purpose built heat exchangers and we have therefore developed an extensive range of standardised designs, most of which can be supplied from stock. This policy of standardisation which we follow for all our products means that customers receive a heat exchanger of proven design and known characteristics.
