The New Standard in Ammonia (NH3) and Carbon Dioxide (CO2) Leak Detection


Industrial Refrigeration – With remote connectivity, we can provide data-driven insight for leak detection and resolution, which reduces refrigerant emissions and reportable emissions events. Bacharach has solutions to help meet IIAR-2, EN 378, and CSA B52 compliance.
