Superior Laundry Systems by Advantage provides energy efficiency solutions for organizationsusing commercial washers and dryers, such as fitness clubs, hotels, and health facilities. One of its specialties is modulating gas valves (or natural gas modulating controllers).
Superior Laundry Systems started out in Northern California and is rapidly expanding throughout the Western U.S. In its first project in Southern California, the company installed three modulating gas valve kits at a Los Angeles area nursing home. SoCalGas assisted with $2,250 in rebates.
Modulating gas valves are a retrofit that make commercial gas dryers more energy efficient. Dryers come with only on or off burner valves, but installing a modulating gas valve adds a medium setting and temperature monitor. Demand for heat decreases during the drying cycle as moisture evaporates; using real time monitoring, the valve goes to medium when appropriate. This avoids overshooting the set temperature and results in shorter, low level burn times, especially in the second half of the cycle. As a result, less natural gas is used, typically by 20-30%, which helps customers save money on their utility bills. There is also reduced wear on linens from decreased exposure to high heat.
