Enclosure Heaters
Enclosure Heaters: practical heating for control panels and industrial cabinets
Enclosure heaters help control heat and moisture inside electrical enclosures where condensation can affect equipment and maintenance. This range covers compact resistive, convection and fan-assisted heating options, including low-voltage units for control panels and higher-output heaters for larger cabinets. A 20W 12-24V AC/DC resistive heating insulator is available for low-voltage applications.
What's in This Range
- 10W convection heater — A compact 120-240V AC/DC DIN rail heater with IP44 protection for enclosure heating where space is limited. View the 10W IP44 convection heater.
- 100W enclosure convection heater — A 120-240V AC/DC DIN rail option with aluminium construction for higher heat output in industrial cabinets. See the 100W enclosure convection heater.
- 250W enclosure fan heater — A 230V AC DIN rail fan heater delivering active airflow for applications that need faster heat distribution inside an enclosure. Browse the 250W enclosure fan heater.
- 350W enclosure heater — A higher-output 350W IP20 option for applications where a compact low-power heater is not enough. View the 350W IP20 enclosure heater.
Who Uses This
Enclosure heaters are commonly specified for switchboards, control panels, automation cabinets and industrial equipment where temperature and moisture need to be managed. Electricians and control-system installers can select between resistive, convection and fan-assisted designs according to enclosure size, available supply and required heat output.
Enclosure Heaters — Common Questions
What heater wattage should I choose for an enclosure?
Start with the enclosure size, ambient conditions, heat loss and the available supply. Smaller cabinets may suit lower-wattage resistive or convection heaters, while larger enclosures may require 100W or higher output. The aim is to maintain the required internal temperature without unnecessarily oversizing the heater.
Are enclosure heaters suitable for low-voltage control panels?
Yes, the range includes low-voltage options such as a 24V DC 250W fan-assisted enclosure heater for systems that need stronger heat circulation. A 20W 12-24V AC/DC resistive heating insulator also provides a compact low-voltage heating option for electrical enclosures and control panels.
Do I need convection or fan-assisted heating?
Convection heaters rely on natural air movement and can be a practical choice for straightforward cabinet heating. Fan-assisted units actively circulate warm air, which can help distribute heat more quickly across larger or more equipment-dense enclosures.
