Take the guesswork out of your superheat adjustments.

TXV Superheat Tuner, part of the Danfoss CoolApps Toolbox, enables service technicians and HVAC installers to optimize superheat with just one or two adjustments on most thermostatic expansion valves.

What used to take hours now takes you only minutes. Simply enter some basic information about the system you are working on, and the TXV Superheat Tuner app will provide you with valve-specific adjustment recommendations. Using this information, you can optimize a cooling system in less than 15 minutes and boost its energy efficiency. The result: your customer saves money on energy costs and you win repeat business.

TXV Superheat Tuner uses a set of advanced algorithms to make its optimization recommendations. These algorithms, developed and approved by some of the best engineers at Danfoss, take multiple factors into consideration, beyond the basic sensitivity of each valve.

You no longer need to use manuals and pressure-temperature conversion tools to perform trial and error adjustments. TXV Superheat Tuner enables you to make precise adjustments from the start, saving you time and delivering a better result.
