Intertec's explosion-proof heaters for processing applications are certified by INMETRO

creates the largest choice available in Brazil for control and instrumentation equipment

August 1, 2017 --- The extensive explosion-proof heater range from the outdoor enclosure specialist Intertec has been certified to Brazil's INMETRO standards. With more than 20 styles of convection and conduction heaters this certification offers process control and instrumentation engineers the largest choice of heaters for hazardous area applications available in Brazil today. The introduction eliminates the need to apply for INMETRO certification for a batch of imported heaters - a commonly used approach that often takes a couple of months. All of Intertec's heaters are additionally available from stock - ensuring rapid delivery.

Among the key applications for the new range are humidity protection and temperature regulation of process analyzers and instrumentation, and heating chambers or 'hot boxes' which are used in many processing areas to maintain media at an elevated temperature and prevent condensation and/or crystallization.

Intertec’s explosion-proof heater range includes over 20 model styles with individual power ratings from 25 to 600 watts and a choice of temperature classes. There are different models to cover the principal application areas of humidity/condensation protection, temperature maintenance and freeze protection, with a choice of convection or conduction heaters in each category. Special profile heaters are available for bringing liquid or gas samples in pipes or cylinders up to operational temperature, together with heat tracing cable and a controller to protect exposed measuring lines.

There is also a series of explosion-proof smart heaters for temperature maintenance that use a patented redundant control method of limiting their surface temperature to ensure safety, which are supplied complete with a precision digital controller. The digital controller is an all-solid-state design with no mechanical switching contacts; it features fully encapsulated electronics and an intrinsically safe external sensor for directly monitoring the temperature of equipment. Numerous other controller and thermostat options provide comprehensive application engineering flexibility for instrument engineers.

Intertec produces an exceptionally wide range of environmental protection enclosures, cabinets and shelters, including many options in pressurized, purge-protected Ex p versions. These can be ordered at the same time as the heaters, or as separate items. Another approach that is popular with many instrumentation engineers and project managers is to use Intertec’s turnkey enclosure assembly service - SAFE LINK. This enables designers to configure a complete system, including the enclosure, heater and controller, and instrumentation if required, using a free software design tool. Once the design is finalized, Intertec will manufacture and assemble the system, and deliver it to the installation site. For exporters, Intertec can also supply heaters certified to many other standards including IEC, ATEX, CSA/NRTL, NEPSI and GOST.
