If heating elements are retrofitted, the heat output at the outer surface of the heating ele- ment must not exceed the maximum values stated in the table below. The following table contains information about the specific heat output PHO as function of ambient temperature: PHO in /cm2Ambient temperature in 0.9 1 to 0 0.8 0 to -2 0.7 -2 to -5 Table3-3: Information about the specific heat output Heating element control The heating elements can be controlled by temperature monitor or an oil temperature mon- itoring system ( Page . The temperature monitor provides signal to be amplified when the minimum and maximum temperatures are reached.
