nVent Hoffman Enclosure Heaters

nVent Hoffman enclosure heaters are designed to control internal enclosure temperatures, prevent condensation, and protect electrical and electronic components from moisture and freezing conditions. These electric resistive heaters are permanently installed inside industrial enclosures and are commonly used in outdoor installations, high-humidity environments, and applications exposed to temperature fluctuations or washdown conditions.
Enclosure heaters function by maintaining the internal air temperature above the dew point of internal surfaces and components. This prevents moisture accumulation even when active cooling is not required and helps protect sensitive equipment from corrosion, short circuits, and cold-related damage. nVent Hoffman enclosure heaters are available in multiple styles, including tube-style heaters, compact heater blocks, and convection or fan-forced designs to suit a wide range of enclosure sizes and heat requirements.
Designed specifically for integration with Hoffman enclosures, these heaters mount easily while preserving enclosure integrity and protection ratings. When paired with Hoffman thermostats or hygrostats, enclosure heaters provide efficient, automatic temperature regulation to maintain internal conditions above freezing or dew point levels. They are widely used in industrial automation, utilities, water and wastewater facilities, process control, instrumentation, lighting, and power distribution panels.
FAQs
Q: What are nVent Hoffman enclosure heaters used for?
They are used to prevent condensation, moisture buildup, and low-temperature damage by maintaining internal enclosure temperatures above the dew point.
Q: When should an enclosure heater be used instead of enclosure cooling?
Enclosure heaters are used in cold or high-humidity environments where condensation and freezing are concerns rather than excess internal heat.
Q: Do Hoffman enclosure heaters require thermostats?
While some heaters operate continuously, using a thermostat or hygrostat is recommended for automatic temperature control and improved energy efficiency.
Q: Do nVent Hoffman enclosure heaters maintain NEMA ratings?
Yes. When properly installed, Hoffman enclosure heaters are designed to maintain the enclosure’s original NEMA and IP protection ratings.
Q: Are nVent Hoffman enclosure heaters suitable for outdoor use?
Yes. They are well-suited for outdoor and harsh industrial environments where temperature swings and moisture exposure are common.
