The THERMOSAFE heats by induction and therefore has no heating elements, the maximum temperature is self-limiting. In the vast majority of applications additional control is not required. If temperature control is necessary, a number of options are available: BF400 Power Controller – Low cost solution for most installations BF400 Power ControllerUniquely designed for use with the THERMOSAFE heater. Open loop control that is simple to install and use, ideal for most applications where a drum needs to be maintained at an operational temperature for a period of time. Burst firing controller enabling adjustment of heater output (0-100%). Selecting 50% will ensure the heater is on for 50% of the time (eg. on for 30 seconds and off for 30 seconds), therefore reducing the maximum drum temperature. Near zero-crossing switching minimizes supply disturbance. Integrated 25A mcb for circuit protection. Whilst the BF400 must be situated in a safe area, (usually in the room where fuses and switchgear are located) the THERMOSAFE heater can still be operated in a hazardous area. The standard supply cable length is 5m, but a longer cable can be fitted on request if the safe area is further away.
