Plano, Texas -- Principal Technology Inc. has created a line of standardized, pre-engineered heater power panels. These heater power panels provide safety interlocks and control of electric heaters for process streams including liquid, gas and aqueous electric fluid heating and vaporizer applications.
Principal Technology's heater power panels have standard heater ranges from 15 to 540 KW at 480V/3 ph/60 Hz and are configured with multiple heater circuits capable of offering redundancy if one or more circuits fails. Modulating control for electric heaters is accomplished using silicon rectified controllers (SCRs) proportional to the customer’s demand signal (4-20 mA), and SCR heat sinks are mounted externally on the enclosure for faster SCR heat rejection. Each unit includes a main three-phase disconnect and control power transformer with Nema 4 electrical enclosure. LED pilot indicator lights for ‘power on’, ‘heater on’, and ‘over-temperature’ protection with reset are included.
