Thermaster OTP Over Temperature Control
High temperature safety controller designed to switch power supply off to heater in the event of low liquid level. This controller is designed to prevent catastrophic damage to plant and equipment.
Utilises a standard Braude sensor held in place with and OTP holder enabling accurate sensing of high element temoerature. This is linked to a Thermaster OTP controller with a single fixed set point to turn of the heater.
The probe may be retrofitted to an existing Polaris Popular heater.
POLARIS HEATERS ARE INTRINSICALLY SAFE

Heater safety and fire resistance
Sep 25 2020
Safety is of paramount importance to manufacturers of electric immersion heaters. We endeavour to make our products as safe and foolproof as we possibly can. However, no piece of electrical equipment is 100% safe unless it is protected by an RCD (Residual Current Device). Some people believe that only an MCB is required, but an MCB does not protect against earth leakage; an RCD is the only device that will provide a rapid (30msec or better) cut off in the event of earth leakage and should be fitted to every installation.POLARIS TEFLON HEATERS ARE INTRINSICALLY SAFEbecause of the materials selected for manufacture and their low watt density which ensures a lower temperature of operation than standard immersion heaters.FLAMMABILITY OF MATERIALSThe materials used in construction of the POLARIS are classified as follows:TEFLON FEP/PFA – These materials are to all intents and purposes non-flammable and will only burn in a pure oxygen atmosphere.PVDF is classified by UL Laboratories as VO self-extinguishing.
