Sensus QR-S Damping Device

The Sensus QR-S Damping Device is a purpose-built mechanical component designed to optimize gas pressure regulator performance in high-demand environments. Engineering teams developed this device to address the rapid ignition cycle requirements of modern high-efficiency boilers, burners, and generators. When high-efficiency equipment triggers an electronic ignition, the sudden draw can create significant negative pressure, often leading to excessive pressure drops or regulator lock-up that terminates the ignition sequence. This industrial damping device mitigates these fluctuations, ensuring stable gas flow without interfering with sensitive burner operations.

For field technicians, the QR-S is an essential field retrofit solution for existing pipe configurations. It is specifically compatible with Sensus 243-8 and Sensus 243-12 regulator models, including -1, -2, -1M, and -2M variations. Built with a rugged diaphragm capable of withstanding 25 psig MAOP, it manages vibration control and mechanical shocks effectively. Integrating this device into your system prevents extreme pressure drops at startup and extends the operational life of the regulator assembly by reducing mechanical stress during high-frequency cycles.

• Enhanced Regulator Response: Significantly decreases response time to meet the instantaneous volume requirements of modern high-efficiency gas equipment.
• High-Efficiency Compatibility: Prevents nuisance shutdowns in HE boilers and HE burners by eliminating extreme pressure drops during the ignition phase.
• Simplified Field Retrofit: Designed for straightforward installation on Sensus 243 series regulators in the field without extensive piping modifications.
• Industrial-Grade Durability: Rated for up to 25 psig maximum allowable operating pressure (MAOP) with a high-flex life diaphragm.
• Internal Pressure Stabilization: Effectively dampens mechanical vibrations to maintain precise set-points during rapid load changes.

Is independent vent piping required for the QR-S?
No, the Sensus QR-S typically does not require independent vent piping to the building exterior, as the diaphragm reacts to the regulator's internal motion without significant pressure differentials.

Will this device impact the regulator's set pressure?
The QR-S allows for the regulator's set pressure to be adjusted while the damping device remains installed, providing flexibility during commissioning.

Which regulator models is the QR-S compatible with?
It is engineered for compatibility with Sensus 243-8 and 243-12 regulators across various body styles and variations commonly used in industrial gas applications.
