Intertec has launched an explosion-proof smart programmable controller for precision temperature regulation of process instrumentation and analyzer enclosures in hazardous environments. Suitable for use with any explosion-proof electric heater from the company's range of compatible heaters, the Smart Controller 2.0 brings flexibility to thermal management. Advanced facilities include fieldbus networking, extensive monitoring and diagnostic routines, programmable temperature ramping, data logging, and temperature monitoring with user-definable limits. The controller has a switching capacity of up to 10A, enabling it to be used with explosion-proof heaters with power ratings as high as 2,300W, depending on the ambient and required enclosure/equipment temperatures and the heater supply voltage. Heater systems based on Smart Controller 2.0 may be used to control the temperature of equipment or the surrounding air in an enclosure or cabinet very accurately, and are especially suitable for use with analytical instruments that need to be maintained at high temperatures and are located in hazardous environments. Typical applications include analyzers handling difficult media in oil, gas and petrochemical processing plants. When used in conjunction with a CP xxxTHERM HI explosion-proof heater, the controller provides an all-in-one solution that does not require separate safety certification. The complete controller/heater system is fully approved to international explosion proof standards including ATEX, IEC, CSA C/US and GOST. There are two versions of controller: the standard version features a compact housing measuring just 57 x 125 x 80 mm and is suitable for IEC-Ex and ATEX Zone 1, 2 , 21 and 22 . When installed in a NEMA 4X rated enclosure, the system is also approved for use in North American hazardous environments rated Zone 1 or 2, Group IIC or Class I or II, Division 2, Group A, B, C and D. The second version, developed for the North American market, is designed to form part of a cable conduit system, and is approved for Class I, Division 1 rated hazardous environments.
