Fact box: Bringing the right gas sensor technology to market
Since the start of the refrigerant transition, our multidisciplinary team of experts has worked together with our customers to explore and test various gas sensing technologies.
We wanted to combine our 55+ years of experience in developing HVACR applications, with the latest research in this area, so we could base our solution on the technology and product design that would deliver the best results for our customers’ systems. Our TC sensor is the result of this collaboration, and it also marks the first step in our gas sensing journey. The next step in the journey will take us to Monterrey, Mexico, where we’re establishing a manufacturing footprint at our Danfoss campus. This location places us in proximity to our customers and will make it easier for us to partner with them to develop new gas sensing technologies. Our local presence will also improve speed-to-market and lead times and reduce transport emissions, so we can effectively meet the market’s increasing demand for sensor technology and support our customers’ growth.
