If you are heat treating products in your manufacturing process, you need to know that they have been exposed to the right temperature for the right amount of time in order to ensure consistent product quality. By passing a Grant OQ610 oven logger – protected by a thermal barrier - through your process, a temperature profile can be produced that will show you exactly what is happening to your products and the process.
Benefits of through process monitoring include improved quality of your product and increased efficiency, reduced energy costs, quality assurance reports for compliance and traceability and complete quality control for your process.

Thermal barrier specification
The performance of a thermal barrier is measured in terms of the exposure time at a particular temperature for a given maximum internal temperature. The performance is closely related to the barrier’s insulation thickness. The table below indicates the allowable exposure time (in minutes) of temperatures for the standard (thermal barrier models assuming a maximum internal temperature of 70°C).

Customised barriers
Thermal Barriers are available in standard sizes or can be customised to suit your specific requirements. For customised barriers we require details of your application, oven aperture size and expected worst case temperature profile.
