HVAC Sensor Solutions

elobau offers a range of float sensors and single point sensors for the HVAC industry. Condensate overflow switches are a cost-effective way to create an environmentally sustainable HVAC system for industrial and commercial buildings. Our HVAC float sensors have multiple set points, including high and low, which offer increased reliability.

Float Switches and Liquid Sensors

Features of our overflow switches include temperature measurement that can be integrated into specific models of our single point sensors. Our single-point sensors and float switches feature a variety of materials including stainless steel, PVC, and PVDF. Liquid float switches will automatically shut HVAC systems off when the sensor detects an issue like clogged drains.
