Industrial Immersion Heaters
We are very proud of our UK manufactured Industrial Immersion Heaters Range, having rotateable, robust alloy terminal boxes with top notch Ingress Protection rated at IP67, 8mm diameter Incoloy 800 sheathed elements ideally suited to British water, and a selection of screwplug sizes in both Brass & Stainless Steel.
We stock the Industrial Immersion Heaters listed below for rapid delivery, but can make bespoke items to suit your specific needs if required. That can include BSP screwplug sizes including 1″BSP, 1.25″BSP, 1.5″BSP, 1.75″BSP, 2″BSP as well as the British Industrial Standard size of 2.25″, which can be fitted with an adaptor to take it up to 2.5″BSP.
Bespoke items usually take a coupla weeks, but can be shuffled to the top of the pile if you are willing to pay a premium surcharge of approximately 50%. Customers only tend to do this when they are desperate, due to a production line being down & costing £££’s due to not carrying a spare. The moral of this story being, CARRY A SPARE, especially if your heaters are not standard (ie, 2.25″BSP and a multiple of 3 in terms of kW power output) and stock as listed below.
