Every pipe or vessel is subject to heat loss when its temperature is greater than ambient temperature. Thermal insulation reduces the rate of heat loss but does not eliminate it. Trace heating maintains the temperature above freezing by balancing heat lost with heat supplied. Normally, a thermostat is used to energise when it measures temperature falling below a set temperature value - usually between 3°C and 5°C and often referred to as the 'set point'. The thermostat will de-energise the trace heating when it measures temperature rising past another set temperature value - usually 2°C higher than the set point value.
Specifications:
Construction:
• Flame-retardant self-limiting heating cable.
• Steel armoured metallic sheath with
minimum electric fields.
• Insulation class I.
• IP67.
• Operating temperature max +50°C.
• Tap warm water should never be higher than +50°C and the self-limiting heating cable should only be energized when there is a risk for freezing, pipe temperature lower than +5°C. The self-limiting heating
cable should be regulated by a thermostat and the sensor installed on the pipe.
• Mechanical strength, armoured class C according to EN60800.
Self-regulating technology - will not overheat.
