Compact enclosures simplify high temperature process analytical applications
Mike Edwards
Products enclosuresIntertec Instrumentation has introduced the Hot Box for outdoor process sampling applications. Designed to accommodate temperatures up to 150°C in compact footprints, the hot boxes employ a combination of conduction and convection heating assisted by a novel air circulation system.
The exact temperature inside the hot box is controlled by the Intertec explosion proof smart controller, which provides programmable digital PID control.
The temperature sensor for the controller can be mounted at the optimum position in the enclosure to ensure accurate control.
A processing plant’s instrument air service can be connected to provide a very low flow, which is introduced into the enclosure via perforated tubing that releases the air between the fins of the heater(s).
This air flow continually moves the warmer air away from the heater, which as a result then maintains a higher heat output, the company says.
