Hygienic Opti-Gard
The hygienic Opti-Gard is equipped with a non-fragmenting, reverse-acting rupture disk with a smooth, uninterrupted surface finish to reduce contamination and maximize stream SIP and CIP procedures. To facilitate installation, the system is designed to fit directly between ISO2852 standard food industry couplings and clamp fittings. Opti-Gard features a performance tolerance of only 5% across a wide range of burst pressures and a 95% operating ratio.

Flo-Tel+ burst detection system
The Flo-Tel+ burst detection system is an upgrade to the Flo-Tel, adding a thermistor to monitor temperature changes that can affect the burst pressure of a rupture disc and other key process parameters. This noninvasive, magnetic system is installed on the vent side of the rupture disc to minimize downtime. Unlike traditional membrane-type detectors, the Flo-Tel+ is fail-safe and only operates when a disc has ruptured, eliminating the possibility of a false alarm. The system can withstand all levels of potentially explosive atmospheres at process temperatures ranging from –100ºC to 300ºC.
