Maritime fan heaters - electricity supply requirements

Our V3.6 and V6 offshore heaters are designed for use with 440V 3 phase 50/60Hz electrical supplies as found onboard ships and offshore platforms.
They are not suitable for standard UK or European electrical supplies.

Choosing the right fan heateron-line heatloss calculator

Before selecting a fan heater it is important to carry out a heatloss calculation to determine the size required. See heater size calculations for details, or use our on-line calculator.

Off shore fan heaters - 1 year warranty

Our offshore fan heaters are manufactured to the highest standards, and we are confident that they are totally reliable. However, in the unlikely event a fault may occur, they have a full 1 year return to base parts and labour guarantee.

Manufactured from stainless steel to resist humidity and corrosion, and strengthened against vibration. Activair maritime fan heaters are designed to provide years of trouble free operation in the toughest offshore conditions.
