DIN or DN Flanged Immersion Heaters are available in an extensive range of sizes.
DIN stands for Deutsches Institut für Normung (German Institute for Standardization) & DN indicates Dimension Nominal.
We can usually turn these Premium Quality, British Manufactured heaters around in 2-3 weeks. If you are losing lots of money due to a dead heater & a lack of forethought in carrying a spare, you can pay a 50% premium for a one week turnaround. We are now more politely calling this the “Distress Price”*.
If your power requirements fall within the range of 12 – 54kW, our FFY Range might be suitable for your needs.
Here at IHUK, we can accommodate any size, ranging from DN 1″ NB (DN25) up to 24″ NB (DN600). With various PN (Pressure Nominale) ratings.
DN25 – DN50 – DN80 – DN100 – DN125 – DN150 – DN200 – DN250 – DN300 – DN350 – DN400 – DN450 – DN500 – DN600
For further details, it is recommended to take a conventional approach and initiate a discussion. Please contact Jamie at 01827 215684. We can explore potential needs for Blind Female Flange Fittings (even if it sounds intricate!), gaskets, bolt kits with nuts and washers, as well as stand-off tubes.
Following the principle of “Measure Twice, Cut Once,” as David emphasized upon receiving the 120kW 415V 1200mm Immersed DN250 10″NB PN16 unit in November ’23.

This table outlines the corresponding DN Imperial to Metric conversions and provides information on the Pitch Circumference Diameter of the bolt ring.
Specifically, it presents precise dimensions for various DN specifications, taking PN16 as an illustrative example.
As breweries (and distillers!) are our favourite customers, we tend to focus on the following 3 sizes, DN50 (3 U bent elements only). Through DN80 (sort of equivalent to the 2.25″BSP size prevalent in industry, so 3 looped elements potentially). Right up to DN125, (which could accommodate up to 9 U bent elements). These heaters are fitted with no screwing required.
As breweries (and distillers!) are our favourite customers, we like to make life easier for our friends who bring happiness & hangovers to us all. Removable Brewery Immersion Heater is a great solution if your budget allows.
A removable heater will allow essential cleaning to be conducted out of the vessel.
The “top hat” female tank ferrule allows the elements to be inserted directly & simply, with a high temperature gasket sitting between a similar “top hat” fixing on the heater.
This housing is all then held in place VERY tightly with a safety clamp. Using a wing nut for easier tightening.
This enables this heater to be rated up to 20 BAR of pressure. Far higher than a screwplug, at 6 BAR, should the need arise.
Bendy One For You, Sir?
This allows for elements to be curved in order to follow the circumference of the outside of the vessel, rather than going straight across the diameter. This greatly increases the amount of element we can squeeze into your vessel, which massively reduces the watt density of the elements. This is of particular benefit to brewers as your ingredients tend to stick to hot element. Like sh1t to a blanket.
Curved elements also lend themselves to a rolling boil, greatly favoured by some brewers. This rolls up the outside , then down in the middle, creating a vortex of sorts. If somebody wants to explain the benefits of that to me, I’m all ears.
It also allows for insertion to avoid any potential clashes with other fixings within the tank.
It would also lend itself to “splaying” the elements, once inserted, to provide greater gaps between the elements.
The potential downside is the physical space involved outside the tank to provide “wiggling in room”.
Plus all the other beneifits and features of our II Range (IP67 terminal box. INCOLOY® 800 sheathed elements) just tweaked.
The biggest benefit though is the ability to soak, powerwash, steam or scrub OUTSIDE of the vessel.
Now this is where the Heath Robinsin creative spirit of brewers can really come into play. We always had ideas about shiny stainless steel tubes, munsen ringed to a wall, to soak your heater in overnight for super easy cleaning. But no need, Niall at Third Barrel Brewing did it with a bit of toilet pipe and some gaffer tape, see images below.
