EXHEAT MFH “Bulldog” offshore portable flameproof fan heaters provide safe portable, hazardous area certified heating and air warming for offshore hazardous areas.

The Bulldog offshore portable fan heater is the world’s first truly portable hazardous area fan assisted heater. The ATEX heaters feature a patented design (GB1614657.3) which utilises salt-water resistant materials to provide a portable heating solution for use in offshore environments where the potentially explosive atmosphere is classified as hazardous area Zone 1 or Zone 2 (IIB+H2) or Zone 21 or Zone 22 (IIC).

Offshore “Bulldog” flameproof fan heaters are certified to meet ATEX equipment directive and are tough and durable with a casing made from steel reinforced polymer. The unit has adjustable feet allowing for the heater to be angled into position and the compact design means it can be easily stored or transported.

Typical heating applications include offshore containers, production platforms, paint curing and stores, spray booths, oil refineries and drilling and fabric maintenance.

The Offshore “Bulldog” can be used with or without ducting to provide a warm stream of air that can be felt up to five metres away, in ambient temperatures as low as -40°C or as high as +40°C.

The hazardous area portable fan heater comes ready to plug and play with the option of fitting a plug, or hard wiring to an isolator unit and can be optionally fitted with an additional safety device above and beyond the requirements of the certification.

The bulldog offshore portable fan heater

features

  • Authorized and certified for offshore applications/installations
  • Available in T3 and T4 temperature classes for hazardous area zones
  • Suitable for ambient temperatures as low as 40ºC and up to +40°
  • Up to 6kW. The heater can be directed at an engineer working in a larger space, or at the same time, warm a mid sized room to a comfortable operating temperature for all within
  • Offshore design includes a standard local isolator, anti-static castors and two side handles
  • Portable and lightweight, allowing for single user manipulation / operation. Can be supplied on a long flying lead to get heat where you need it
  • The Bulldog’s design increases efficiency, providing a warmer flow of air for the operator at up to 5 metres
