For Galden® grades, a general recommendation is not to install a Heater Watt Density higher than 4÷5 W/cm², in order to avoid instability in heater surface temperature for low flow units (i.e. Fluid reservoir in the TCU).
Having the heater section where fluid flow is present near the outlet of the pump, it will allow higher Watt Density heaters to be used.
The critical breakdown is ~14 W/cm². We recommend 4 W/cm². The decision to go beyond this level should be made by the customer.
