Most pumps are heated by thermal oil or steam, but many users want to heat the pumps electrically as it takes a large investment to establish and run a thermal oil heating system for small units. The electric heating system in the small ROTAN® pumps is based on a heating element which is placed in the middle of the pump, where it is most effective.

No re-sealing of the heating pipe system after servicing the pump. For more information on Industry solutions, please visit www.desmi.com MARINE & OFFSHORE DEFENCE & FUEL
