SGD43S-M3-S5
UpcomingFlexible and complete refrigerant leakage detection system for modern HVAC systems
<p>The SGD43S-M3-S5 is part of our SGD4x series of A2L refrigerant detection products, specifically designed for the HVACR industry as a complete refrigerant detection system (RDS). It is based on the thermal conductivity measurement principle and features a dual dry-contact relay output that can trigger a signal relay to start a blower, switch off the load or warn a control board. Easy integration and installer-friendly feedback is enabled by a status-indicating LED for quick visual feedback. </p><p> </p><p>With its fast response time and broad compatibility with A2L refrigerants thanks to its versatile multi-refrigerant calibration, it is an essential component for both residential and commercial HVACR systems. The SGD43S-M3-S5 ensures effective leak detection and complies with stringent industry standards, including UL60355-2-40. It offers dual calibration in a single device for R-454B and R-32 for HVAC applications.</p>
