When dimensioning the heat exchanger for heating, it
must be observed that the coolant tap on the engine
only can allow a limited water flow and temperature
drop.
Max allowed water flow
8 l/min.
Max allowed temperature drop 30°C (86°F)
The external circuit must be designed to restrict the
flow to not exceed the allowed flow. The external cir-
cuit is by-passing the engine cooling circuit, to great
flow may cause engine overheating.
If the heating is designed so that it can dissipate
more heat whit the available quantity of coolant, the
engine cannot reach its appropriate temperature de-
spite a closed thermostat. This must be avoided by
heating dimensioning.
