HPD Hazard Protection Device
The HPD is a level controller which works with sensors fitted to the Polaris heater. The sensor are Braude filaments which will not corrode in even the most corrosive of solutions.
The controller operated by passing a small ac current through the sensors which will detect the presence of a liquid. If there is no liquid present the controller will deault to the off position and the heater will be turned off thus ensuring safety of the heater and the tank.
HPD is best ordered at the time of ordering the heater ensuring the sensors are correctly positioned. It is possible to retrofit sensors where there is no other choice.
Example of Applications
- Low level protection for all Popular and Modular heaters
- Integral to Polaris Popular heater
- Prevents heater failure
- Tamperproof controller
- Non corrodable filament sensor
- Can be retrofitted to heater
- Prevent catastrophic plant failures

Polaris Modular Tank Heater
Sep 25 2020
The Polaris Modular fluoropolymer immersion heaters are designed for use where aggressive chemicals need to be heated to temperatures up to 100°C, and have optimum chemical resistance against corrosion caused by chemicals such as nitric, hydrochloric, sulphuric and hydrofluoric acids, and are inert enough to be used where non-contamination is a requirement.They are small enough to fit behind anode baskets and in other confined operating areas; the Polaris Modular will cope with all the special requirements experienced by the metal finishing and allied industries.
Polaris Popular Tank Heater
Sep 25 2020
The Polaris Popular fluoropolymer immersion heaters are designed for use where aggressive chemicals need to be heated to temperatures up to 100°C. All heaters have optimum chemical resistance against corrosion caused by chemicals such as nitric, hydrochloric, sulphuric and hydrofluoric acids, and are inert enough to be used where non-contamination is a requirement.The element has an open construction to allow free flow of liquid across the surface and to limit solid retention, which is particularly important when used in solutions which generate solid deposition such as Electroless Nickel and Copper plating processes.The heater is thin enough to fit easily into confined spaces eg. behind anode baskets.Popular Classic can be supplied with hanging brackets for vertical mounting or standoffs for horizontal mounting. The integral Braudeflex lead has no junctions and is continuous and flexible.Popular Flex is supplied with a spliced connection to an electrical cable if you a longer lead with a flexible connection is required, and where the presence of a join in the cable is not a problemPopular Cylindrical is for the tanks where a conventional flat model will not suit.
