Coiled elements for even heating
A spiral immersion heater is a tubular heating element wound into a coil. Coiling puts a long heated length into a compact space and spreads the heat through the liquid, so a tank or vessel heats quickly and evenly.
Anchor Marine Engineering manufactures spiral tubular immersion heaters at its Al Jadaf workshop for heating water, oil and chemical solutions in tanks and vessels.
Each coil is formed to your diameter, height and terminal position and built to your voltage and wattage, from one replacement to bulk supply, and tested before delivery.
They are also called coil immersion heaters, coil heaters or spiral heating elements.

Design
Why a coiled element heats evenly
Winding the element into a spiral fits more heating length into the space and spreads it across the tank, rather than concentrating the heat in one place.

Built to order
What we need to build your spiral heater
There is no fixed catalogue size. Each heater is made to the specification of the equipment it is for, or matched to a sample of the old one.
| Detail | Why it matters |
|---|---|
| Voltage & wattage | Sets the electrical design and heating rate |
| Coil diameter & height | Sized to fit inside your tank or vessel |
| Terminal position | Where the ends leave the coil |
| Sheath material | Chosen to suit the liquid; matched to your sample or specification |
| Liquid heated | Water, oil or chemical solution |
| Mounting | How the coil is held and connected in the tank |
