Enclosure Heaters
Enclosure heaters are used to maintain stable internal temperatures within electrical enclosures, helping protect sensitive equipment from low temperatures, condensation, and corrosion. RSP Supply offers a selection of enclosure heaters manufactured by Hoffman, designed for use in industrial, commercial, and outdoor environments where temperature fluctuations may impact equipment performance and reliability.
These heaters are available in a variety of heating capacities, styles, and mounting options to accommodate different enclosure sizes and applications. Common enclosure heater types include convection heaters, fan-assisted heaters, radiant heaters, resistance heaters, and flexible silicone rubber heaters. Many models are designed for compact installation and are available with panel-mount plates or DIN rail mounting for simplified integration inside the enclosure.
Condensation control is an important consideration when using enclosure heaters. If internal temperatures rise too quickly or unevenly, moisture can form on enclosure walls and components, leading to corrosion or electrical damage. For effective moisture management, enclosure heaters are often used alongside ventilation, fans, or dehumidification solutions to maintain proper temperature and humidity balance. Heater selection should always consider enclosure size, ambient conditions, power requirements, and applicable safety standards, especially in hazardous or regulated environments.
FAQs
Q: What are enclosure heaters used for?
Enclosure heaters are used to prevent low-temperature damage, condensation, and corrosion by maintaining a consistent internal temperature inside electrical enclosures.
Q: What types of enclosure heaters are available?
Common types include convection heaters, fan heaters, radiant heaters, resistance heaters, and flexible silicone rubber heaters. Each type is suited to different enclosure sizes and environmental conditions.
Q: What are silicone rubber enclosure heaters?
Silicone rubber enclosure heaters are flexible heating elements that can conform to the shape of the enclosure or equipment, making them suitable for tight spaces or irregular surfaces.
Q: Are enclosure heaters available for hazardous locations?
Yes, certain enclosure heaters are designed for hazardous locations and must meet specific safety standards to reduce the risk of fire or explosion. Proper selection is critical for these applications.
Q: What does RoHS compliance mean for enclosure heaters?

Common modifications or accessories that are used to enhance electrical cabinets
Lighting kits. Lighting kits are often used in outdoor applications. There are many different styles of lighting kits that can be used, but LEDs have become the preferred lighting solution in the past several years.
Pressure switches. Pressure switches operate on a spring and react to the cabinet door opening and closing. They can be used for lights, intrusions alarms and exhaust fans.
Passive air vents. Passive air vents allow natural air circulation to flow through a cabinet providing proper ventilation.
Enclosure fans. Enclosure air fans are used when more ventilation is required. The size of the fan will depend on the size of the enclosure as well as the amount of air that needs to be circulated.
Air conditioners. Air conditioners are used when ambient air circulation is inadequate to cool the cabinet. The air conditioner size will depend on the enclosure size, ambient air temperature and heat generated within the cabinet.
Heaters. Heaters are used when a cabinet is located in areas that may be exposed to cold temperatures.
Locking mechanisms. Locking mechanisms are used to secure cabinets.
Conduit hole seals. Conduit hole seals are used on cabinets that have holes that need to be plugged after conduit has been removed.
