Flange immersion heaters made in Dubai
Heaters for large tanks and vessels
A flange immersion heater is a group of tubular heating elements fixed to a flange, which bolts to a matching flange on the tank so the elements sit directly in the liquid. The bolted mounting holds a large heater securely and lets a lot of heat go straight into the water, oil or solution.
Anchor Marine Engineering manufactures flange immersion heaters at its Al Jadaf workshop for water, oil and chemical heating in industrial settings, and marine heating elements for fuel oil systems and HFO tanks. We also make ceramic removable flange heaters, with ceramic insulation and a removable flange, for chemical, fluid and water-based applications.
Every heater is built to your voltage, wattage, flange and element length, from one replacement to bulk supply, and tested before delivery.
They are also called flanged immersion heaters or flange type immersion heaters: electric flanged immersion heaters for tanks, and flange water heater elements for calorifiers and hot water storage.

Design
How a flange immersion heater is built
Several tubular elements are bent and fixed to a flange plate, with the terminals on the outside of the tank. The flange size, number of elements and immersed length are set by the tank and the heat it needs.

What is a flange immersion heater?
It is a set of tubular heating elements fixed to a flange that bolts onto a matching flange on a tank, so the elements heat the liquid directly. It is used where a large volume of water, oil or chemical solution has to be heated.
Can you make a flange heater to match our old one?
Yes. Send the old heater as a sample, or its drawing or specifications, and we will manufacture a matching flange immersion heater.
What is a ceramic removable flange heater?
It is a flange immersion heater with ceramic insulation and a removable flange. We manufacture them for efficient heating in chemical, fluid and water-based applications.
Do you make flange heaters for fuel oil and HFO tanks?
Yes. We manufacture marine heating elements for fuel oil systems and HFO tanks.
Which details decide the design of a flange heater?
The voltage and wattage, the flange size and drilling, the immersed length, the number of elements, the sheath material and the liquid being heated.
