The Thermal Guardian™ Diaphragm Seal is Haygor’s newest patented technology.  Allowing precise pressure measurement of extreme high temperature processes ranging up to 1200°F (650°C), the advanced patented design dissipates heat and acts as an additional temperature barrier between a standard diaphragm seal and the pressure instrument, protecting from extreme temperatures, yet still allowing for ultra-precise pressure measurement. 

Thermal Guardian is uniquely designed and proven to perfectly complement without impacting performance, response time, or accuracy of the mating pressure instrument.  The secondary diaphragm barrier, combined with its liquid metallic based internal fill and specifically designed cooling fins for heat dissipation, create superior protection never before seen in the industry. 

It can be installed with direct mount or capillary mount diaphragm seal systems, attached to gauge pressure or differential pressure and is available with all standard and exotic materials and secondary fill fluids.  Installed with Haygor’s patented Temperature Compensating Diaphragm Seal system creates the “Perfect Diaphragm Seal System,” allowing for extreme process and extreme ambient conditions.

Traditional diaphragm seal systems offer thermal protection up to 600°F (315°C) with some offerings claiming up to 850°F (450°C). However, these offerings all come with “side effects,” inaccurate measurements, slow response times, dangerous fill fluids, etc.  Other ineffective solutions include costly designs that require special installation or heat tracing.  The Haygor Thermal Guardian Diaphragm Seal is not only cost effective but solves one of the most difficult and problematic issues with diaphragm seals and pressure measurement.  This new technology allows for stable and accurate measurement of processes exceeding yesterday’s limitations, creating new ways of measurement without limitations.

Coupled with Haygor’s complete lineup of diaphragm seals, this groundbreaking design and technology is the key to accurately measuring today’s everchanging refining process.
