Engine Heater SafeStart 500 series

Special flange heaters

Heaters in the 500 series are manufactured with special flanges designed for engines with caps in stead of frost plugs between the engine and the coolant tank.

Description

Heaters with special flanges or special fasteners are identified with the DEFA number series 501-2599. Some engines have one of several types of caps instead of a frost plug between the engine and the coolant tank. DEFA manufactures a flange for these heaters which is identical to the original cap. The heater is fastened with bolts. A gasket or an O-ring is used to form the seal. There is also a heater available in this series which consists of a flat or head shaped flange, and which is fastened with a holder.

Engine pre-heaters are supplied separately because of specific necessary adaptations to each individual engine and vehicle type.

Use

Normal usage – DEFA engine heaters are designed for “normal usage”. DEFA defines “normal usage” as; 3 connections for 3 hours pr. 24 hours for 150 days (5 months) a year.

Professional use – For use emergency vehicles or other vehicles where the heater is in use continually, yearly controls are necessary. It might be necessary to install a replacement heater. Yearly service cost will not be covered by DEFA AS.
