| Industrial Immersion Heaters |
Our range of industrial immersion heaters are specially designed for commercial
environments, unlike domestic immersion heaters our industrial versions have the
ability to heat large volumes of fluid.
Industrial immersion heaters are ideal for:
- The regulation of fuel temperatures
- Food production and brewing
- Pharma- & chemical-industry handling of product and ingredient temperatures
- To stop the freezing of pipes in sewage and plumbing.
We stock a wide range of industrial immersion heaters ready for immediate
dispatch, however where required they can be customised for different voltage or
wattage (with a 2 week turnaround time).
| Acid and Alkali Immersion Heaters |
If you are working with substances that have a PH level less than 7, these
fluids are classed as acidic. If the pH level is greater than 7, these are
classified as Alkali. Our complete range of VAT heaters can be used to heat mild
acids and alkali.
| Some everyday examples of acidic substances: | Some everyday examples of alkali substances: |
|
- Battery Acid: pH less
than 1.0 - Black Coffee: pH ~5.0 - Milk: pH 6.5 to 6.8 - Orange Juice: pH 3.3 to 4.2 - Stomach Acid: pH 1.0 to 1.5 - Vinegar: pH 4.0 to 5.0 |
