Explosion-proof heater
September 1st 2007

Intertec has launched its smart programmable heater for hazardous area applications.

Approved for worldwide Zone 1 use, by IEC, ATEX, GOST and CSA, Intertec's smart heater consists of a heating element plus a networkable digital PID controller with encapsulated electronic circuitry. Dual temperature sensors are supplied; one intrinsically safe sensor that can be freely positioned in the enclosure or cabinet, another embedded in the heater body. These sensors allow the system to control air temperature precisely while also ensuring safety in hazardous areas by limiting the heating element's maximum surface temperature to the required 'T' rating - from T3 to T6 (200 to 850C). A range of different styles and sizes of elements including finned, block and fluid heaters are available – as well as types that mount directly onto ANSI/ISA standard SP76 analyser substrates - to suit the application requirement.
