about us:

For over 50 years we have been one of the leading manufacturers of heat-exchangers for the ship-building, the motor-building and the process engineering industry. We are occupied us with the manufacturing of bare- and fintube-heat-exchangers, and the manufacturing of safety double tubes-heat-exchangers, which are especially used for recooling or heating of water, oil and air.
Qualified employees and modern manufacturing-methods in new production- and administration-rooms guarantee the development and manufacturing of high-grade products.

Our workmanship covers the heat-technical laying-out of the heat-exchangers, the dimensioning of the component parts, the production of the manufacturing-foundations, as well as the manufacturing of the units. Certainly our constructions correspond to the demands of the classification-companies and of the technical-supervision-union. Especially for very difficult applications we offer heat-technical solutions, the demands and special wishes of our customers being carefully considered.
Due to the using of different materials our units can be adapted to nearly every working condition. High efficiency at relative small dimensions, exchangeablity of all parts and small expense in maintenense are some of the outstanding qualities of the Prang-heat-exchangers and are determinates of the good valued selling-price.
We are certificated according to DIN EN 9001 through the TÜV-Rheinland and are admissioned by HPO according to AD-leaflet. Leading companies of the ship-building, motor-building and the process engineering industry use PRANG-heat-exchangers worldwide.
