EXHEAT FWD Flameproof Air Warmer

T3-rated heater ideal for use in small, hazardous work or storage areas

The EXHEAT FWD Flameproof Air Warmer is specifically engineered and certified for heating small work or storage spaces 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. It can also be used in Hazardous Area Zones 21 and 22, which involve explosive dusts in Groups IIIA, IIIB and IIIC.  

With a heating capacity of up to 2kW, the EXHEAT FWD unit provides four heating power options. This flameproof air warmer is exceptionally efficient and suitable for challenging and hazardous environments where conditions can be extreme. Applications include but are not limited to the following:

• Aircraft Hanger Service Bays
• Ammunition Depots
• Battery Stores
• Biogas Plants
• Chemical Plants
• Compressor Enclosure
• Container heating
• Crane Cabins
• Dusty Environments
• Explosive Stores
• Firework Factories
• Fuel Servicing Areas
• Gas Installations
• Offshore Installations
• Paint / Solvent Stores
• Skid Enclosure
• Spray Booths
• Sugar Refinieries

The air warmer boasts a sturdy steel construction, with its enclosure made of fabricated carbon steel. Featuring an IP66 rating, it ensures the unit's ability to endure powerful water jets from all directions and offers the highest level of protection against dust. A stainless steel option is available for specific requests. To enhance its durability, the air warmer is coated with a corrosion-resistant powder coat, featuring an attractive orange and grey colour scheme. This coating not only adds aesthetic appeal but also safeguards the unit from potential damage caused by moisture and other environmental elements. 

The EXHEAT air warmer functions effectively within a wide temperature range of -60°C to +40°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 T3 temperature rating, ensuring that the maximum surface temperature of the FWD unit does not surpass 200°C. Therefore, the air warmer is appropriate for use in environments where flammable substances have ignition temperatures higher than the equipment's maximum surface temperature. 

To enhance user convenience, the FWD heater is equipped with replaceable heating elements. This feature enables hassle-free and cost-effective maintenance, as each heating element can be individually replaced. By facilitating quick and straightforward element replacement, the heater ensures minimal downtime and optimal efficiency for your heating system. Furthermore, the unit provides options for both 240v and 110v, allowing for flexible installation and compatibility with various electrical systems. 

To ensure proper installation, the FWD heater should be mounted horizontally, either on a floor or a wall, enabling unrestricted airflow around the unit. It is supplied with pre-drilled support feet as standard equipment. If desired, the heater can be controlled using remote mounted thermostats from the EXHEAT Industrial range, which is available separately. If an integrated adjustable thermostat is required, you may consider the FWD-T Flameproof Adjustable Air Warmer. For further information, please don't hesitate to contact us.

ATEX Certified: The EXHEAT FWD Flameproof Air Warmer is an air warmer intended for use in explosive gas atmospheres (Group IIA, IIB, IIC) and dust atmospheres (Group IIIA, IIIB, IIIC). It is flameproof and suitable for use in Hazardous Area Zones 1, 2, 21 and 22.

Up To 2kW Heating Capacity: The EXHEAT FWD unit offers four options in terms of heating power. The flameproof air warmer produces an outstanding amount of heating power for hazardous environments where conditions can be extreme. Applications include, but are not limited to, aircraft hanger service bays, biogas plants, chemical plants, explosive stores and dusty environments. 

Robust Steel Construction: The unit is enclosed with fabricated carbon steel, which gives it an IP66 rating. It can withstand powered water jets coming from all sides and has the highest level of dust protection. A stainless steel option is available for special order. 

Corrosion Resistance: The air warmer is finished with a layer of corrosion-resistant powder coat. Highlighting an orange and grey colour combination not only adds aesthetic appeal but also protects the unit from damage caused by moisture and other environmental factors.
