Remember all of the stuff that applies to all water immersion heaters, plus the key consideration for breweries is ease of cleaning.

Our existing ranges of immersion heater had limitations when used in brewery applications.

The PII Range has many benefits, including bespoke screwplug size, immersed length, double stat pockets, etc, all with a 2 week leadtime, BUT as you can see from the images (particularly the 5th) our aim of maximising the length of 8mm diameter element, hence double looping rather than merely U bending, leads to a fair old ‘clump’ of elements.
Now, we are fully aware that all of you happy brewers are only boiling clean water (ha, ha) and are fastidious in cleaning thoroughly with a jet wash between every brew (chuckle, chuckle), but still, this ‘clump’ led to build up of ‘mystery stuff’ over time, leading to hot spots, element splitting and heater death.

The PIH Range doesn’t suffer from this issue, as it is only u bent elements. Problem is, as can be seen on the 3rd picture, the 16mm elements have very little gap between them, again, preventing efficient cleaning.

So, the Gaffer designed the PCAB Range in conjunction with one of our Italian suppliers. These are a 10mm, u bent element, which has masses of gap between the elements (see pictures 2, 4 & 6) to enable efficient jet washing of the element to clean off any deposits. We will never be able to deviate from the specs on the website, as we have to buy in bulk with horrible lead times. But thankfully, the Gaffer seems to have pitched the immersed lengths just right, and the watts density at around the 60w/in² mark, seems to be just right.

Even with the antique gear that some of you chaps are recycling for 21st century brewing, no one has needed any screwplug size other than 2.25″, tho I suppose we could throw on an adaptor to make them 2.5″ if needed.

So if you fancy buying an immersion heater that was actually designed for brewers, give me a call, details on the website. Feedback from new and existing customers is greatly appreciated, via the feedback button on the website or via Facebook or Twitter.

Remember all of the stuff that applies to all water immersion heaters, plus for oil heaters our target is to get the watts density down to 12w/in² or below.

POIL Oil Imersion Heater

The POIL Range has many benefits, including bespoke screwplug size, immersed length, double stat pockets, etc, all with a 2 week leadtime. The 8mm elements can be double looped to fill your maximum available immersed length with a large overall length of element. As can be seen in the fifth image on our PII web page, the elements drop from the screwplug to your maximum available immersed length, before looping back up to within a few inches of the screwplug, before dropping back to full immersed length, then returning back up to the screwplug. This allows us to fit nearly twice the length of element possible in a plain U bent element. For example, in 24″ of maximum immersed length, we could use an 84″ element double looped.

if you have a very large tank with a massive maximum available immersed length, you may choose not to double loop, but to have plain U bent elements over a meter in length.
