Operating
The bottom aluminium part of the heater is in direct contact with ECD housing. The junction
transmits 5W of thermal energy from heater to housing. It is recommended to apply thermal
conductive paste on the surface of heating element to enhance thermal conductivity.
Aluminium housing has surface of 201cm^2 with heat conductivity 0,034 W/m
o
K. ECDh-5 will
raise the temperature of housing for 15
o
C above ambient. Response was measured with
ECDh heater installed on bare ECD, meaning ECD drain was not connected to any piping
system and there was no condensate flow through housing. When dimensioning and
installing condensate drain and heater it must be taken in to account, that connecting ECD
on compressed air network will increase conductive surface and thermal losses, therefore
lowering the temperature of drain housing. Any condensate flow through ECD drain will
further alter temperature response. It is up to user to take these environmental variables in
to account. If necessary, it is possible to thermally isolate ECD drain housing and piping
network from environment and reducing heat losses.
