ATEX Certified: The EXHEAT HEF Hazardous Area Enclosure & Cabinet Heater is a compact heater intended for use in explosive gas atmospheres (Group IIA, IIB, IIC). It is suitable for use in Hazardous Area Zones 1 & 2.
Up To 500W Heating Capacity: The EXHEAT HEF unit offers five options in terms of heating power. The heater produces a decent amount of power to heat enclosures and cabinets in hazardous environments where conditions can be extreme. Applications include, but are not limited to, container skid housings, fire hose cabinets and motor enclosures/cabinets.
Robust Steel Construction: The unit comes with a 316 perforated stainless steel casing. It is a corrosion-resistant alloy that contains molybdenum, which enhances its resistance to pitting and crevice corrosion in chloride environments. The excellent durability and corrosion resistance make it suitable for use in harsh environments such as offshore platforms or chemical processing plants.
Extremely Flexible Temperature Range: The EXHEAT enclosure heater operates from -60°C to +80°C, which is suitable for use in a variety of environments, including industrial settings where extreme temperatures are common.
T4 Temperature Rating: With a T4 rating, the maximum surface temperature of the HEF unit will not exceed 135°C, which suggests that it is suitable for use in environments with substances that have ignition temperatures higher than the maximum surface temperature of the equipment.
Flexible Mounting: The HEF heater can be mounted in any orientation with appropriate securing bolts , making it versatile and adaptable to various installation settings. It allows for easy integration into existing systems without the need for major modifications or additional equipment. The mounting can be done through the mounting feet or DIN rail holes.
Compact Design: The design of the cabinet heater is compact and low profile. It requires minimal space for installation. It is intended to enable closer installation proximity to internal components and cables. The minimum installation distance from these elements and cables is 100mm.
Self-Regulating Operation: The HEF heater comes equipped with self-regulating elements, which automatically decrease the energy output as the surrounding temperature increases. Therefore, it can be used without a thermostat. If comprehensive temperature control for an enclosure is desired, it is advised to use the heater together with flameproof air sensing thermostats such as AFT, HFT or FXT. Please don't hesitate to get in touch with us for more details.
Voltage Options: There are 240v and 110v options available for the unit. This allows for flexibility in installation and ensures compatibility with different electrical systems.
The EXHEAT HEF Enclosure & Cabinet Heater is specifically engineered and certified for all instrumentation and switch gear applications in hazardous areas. It is suitable for use in Hazardous Area Zones 1 and 2, which consist of explosive gases in Groups IIA, IIB and IIC. With a heating capacity of up to 500W, the EXHEAT HEF unit provides five heating power options. This cabinet heater is exceptionally efficient and suitable for challenging and hazardous environments where conditions can be extreme.
The enclosure heater is built with a robust steel structure. Its perforated stainless steel casing is made of 316-grade alloy. This alloy is highly resistant to corrosion and contains molybdenum, which enhances its ability to withstand pitting and crevice corrosion in environments with chloride. The exceptional durability and corrosion resistance of this heater make it ideal for demanding settings like offshore platforms or chemical processing plants, offering quick and precise temperature control.
The cabinet heater is designed to be compact and have a low profile, requiring only a small amount of space for installation. Its purpose is to allow for closer proximity to internal components and cables. The minimum distance required for installation from these elements and cables is 100mm. The HEF heater offers flexible mounting options, as it can be securely mounted in any orientation using the appropriate bolts. Mounting can be achieved through the use of mounting feet or DIN rail holes. This versatility enables seamless integration into existing systems without the need for significant modifications or extra equipment.
For the convenience of users, the HEF heater is equipped with self-regulating elements that reduce energy output as the surrounding temperature rises. This feature eliminates the need for a separate thermostat. However, if precise temperature control is required for an enclosure, it is recommended to use the heater in conjunction with flameproof air sensing thermostats like AFT, HFT or FXT. For additional information, please feel free to contact us.
The EXHEAT cabinet heater functions effectively within a wide temperature range of -60°C to +80°C. This highly adaptable temperature range makes it suitable for diverse environments, such as industrial settings where extreme temperatures are frequently encountered. It carries a T4 temperature rating, ensuring that the maximum surface temperature of the HEF unit does not surpass 135°C. Therefore, the heater is appropriate for use in environments where substances have ignition temperatures higher than the equipment's maximum surface temperature.
Furthermore, the unit provides options for both 240v and 110v, allowing for flexible installation and compatibility with various electrical systems. Applications include but are not limited to the following:
Accumulator System Cabinet, Acoustic Enclosure, Air Heating for Instrumentation, Anti Condensation Heater, Anti-Freeze, Battery Cabinet Heater, Cabinet, Chemical Injection Cabinet, Compressor Enclosure, Compressor Frame Enclosure, Condensation Prevention, Control / Monitoring Panels, Control Housing, Diesel Generator Enclosure, Electrical Panel, Enclosure, Fire Equipment Cabinet, Frost Protection, Gas Seal Panel, GRP Enclosure, Heating Cabinet, Instrumentation Cabinet, Instrumentation for Compressor Package, Junction Boxes, Machine Enclosure, Manifolds, Motor Cases/Enclosures, Motor Enclosure, Motor/Generator, Offshore Cabinet, Offshore Panel Heater, Outdoor Telecommunications Cabinet, Panel for Compressors, Panel Heaters, Power Distribution Panels, Pump Enclosure Safety Stat, Silo Base Enclosure Warming, Skid Enclosure, Switchgear Panel/Cubicles, Temperature Fluctuations, Transformer Enclosures, Transmitter Enclosures, Valve Blocks, Wardrobe
