Bottom mount immersion heater
These immersion heaters on a screw plug or a flange are designed to be mounted in the tank bottom from the interior. The height of the heating circuits is generally reduced to the minimum in order to allow for major variations in the liquid level.
The circuits arranged in layers or on spools allow installing high power densities.

The immersion heater, which combines several tubular elements and a monting attachment, is the best adapted solution for heating fluids. (Water, oil, fuel, solvents, flowing gases, baths for surface treatment, etc.).
The standard models, on screw plugs or with standardized flanges, offer you optimized solutions. Many standard references are available on stock or deliverable in only a few days.
Thanks to our experience, we can help you define the product you are looking for (kind of metal sheath, watt density, type of assembly, regulation, etc...).
Screw plug immersion heater
Usually made up of 1 to 6 circuits welded or brazed to a threaded plug, the screw plug immersion heaters are currently used for small or medium power ratings.
Electrowatt developed several standard series adapted to current applications and delivered on stock or in a few days.
For special applications, Electrowatt conceives the immersion heater to your requirements. A large stock of plugs with ISO or BSP threadings allow us to rapidly satisfy the most varied requirements.

Heatflon® Serie PH 1 - 9
Heatflon® heaters of the PH series consist of a stainless steel tubular radiator sheated in PFA. The head of the heater is made of PTFE and the connecting cable of PFA. Heating zone, head and connecting cable are welded together watertightly as a result a complete immersion in aggresive media is possible.
All devices of the PH series are earthed and approved by association of German engieers (VDE).
As an optional extra, all heaters can also be pre-equipped for a thermal monitoring. Users who purchase a special controller are then able to monitor the internal temperature between the stainless steel heater and the PFA tube, thereby reducing substantially the risk of fire. Heatflon® tubular radiators of the PH series are available for various surface loads, eg:
2,2 W/cm² - 1,5 W/cm² - 1,0 W/cm², applicable dependent on the specific media.

Screw Plug Immersion Heater - GRIN
Gaumer's newest screw-plug design incorporating stainless steel fittings and swedged cartridge heaters (1/2" NPT and 3/4" NPT).
|
|
Immersion heater with ceramic core element
These immersion heaters consist of a ceramic core heating element incorporated in a cylindrical sheath made of materials adapted to the heated fluid.
This arrangement offers many advantages :
- A wide choice of materials for the sheath : steel, all stainless steel, titanium, pyrex®, teflon®, etc.
- A low watt density for "fragile" fluids.
- A wide tolerance to the clogging of the heating circuits.
- The possibility of replacing the heater without having to empty the container.

Watt-Flex Replaceable Immersion Heaters
Heating an acidic or caustic solution in an immersion application can be a difficult and often dangerous procedure. Dalton’s Watt-Flex replaceable immersion system eliminates the complication of changing the heater and draining the tank.
Dalton Electric’s Watt-Flex cartridge heater and immersion well system use a sheath with a welded endcap and NPT fitting that screw into the side of the tank. The sheath becomes a permanent part of the equipment. The cartridge heater is then inserted into this well and held in place with a flange. It can be removed and replaced with ease.
