1.25″BSP Immersion Heater.

Description

Shop for Industrial Immersion Heaters

A 1.25″BSP Immersion Heater has certain limitations.

With a circumference of 131 mm and a diameter of 42mm, it is only possible to fit 3 x 8mm U bent elements and 1 stat pockets onto the screwplug, and thus it could be a Single or Three Phase immersion heater. It is not possible to loop the elements to reduce the watt density, as the resulting element bundle would not fit thru the hole.

• Available at any kW loading from 500w up to 27kW.
• 1.25″BSP only available in brass.
• Available with 2 thermowell at 7, 11 or 18″ for thermostats / cutouts.
• 2 M25 cable entry glands as an option.
• Available with no thermowell if specified by the client. If you don’t need it, omit it from the build, as it is an unecessary weak point.

Within the limitations listed above, it is best we have a conversation about your 1.25″BSP Immersion Heater needs, so call Jamie on 01827 215684 to discuss, in order to co-design the best heater to suit your needs. Your maximum immersed length will be key, with only 2 looped elements to play with, so get your tape measure out, keep it stiff, and stick it through your hole to see how long we can go with those elements. And don’t have a stat pocket unless you really need one. There are benefits to having your heater made bespoke as it allows you to precisely hit your requirements, rather than taking a “Best Fit” off the shelf.

Plan B.

Should you decide that these limitations are too restrictive, there is always the rather drastic & expensive option of changing your 1.25″BSP fittings for a more luxuriant, industrial standard 2.25″BSP entry fitting. This will require you to know a friendly fabricator to lop off your 1.5″ fitting, cut a 70mm hole in the vessel, then weld one of these lumps to your vessel.

…or here in Carbon or Mild Steel – and even cheaper here if you don’t mind a funny shape.

We used to stock stuff like this, but since the world and it’s prices went mad, it’s just not worth the bother anymore, so ebay is your friend.
