Q: Technology today seems to change by the minute. Could you bring us up-to-speed on new developments in faucet technology?
A: Sure. The technology that goes into electronic faucets and flush valves has evolved greatly over the last few years. From our beginning, Delta has sought out innovative solutions to help people use water in better ways. And one of those solutions is Delta’s H2Optics™ Technology.
Q: And what is that exactly?
A: H2Optics Technology is one of the most advanced sensing technologies in the industry today for faucets and flush valves.
Typical infrared technology works on the intensity of light, which may detect outside influences and cause unnecessary activation of a sink or toilet. Faucets and flush valves that feature H2Optics Technology utilize advanced infrared sensing technology that calculates the distance, and then activates when an object is placed within a certain range. So, they operate consistently, time after time. Even with typical interference factors like dark clothing or lighting conditions.
Q: It seems that technology would impact water efficiency?
A: It does. Faucets and flush valves featuring H2Optics technology are definitely water efficient and help contribute to LEED certification. The flow rate of faucets featuring H2Optics technology ranges from 1.5 gpm to 0.5 gpm.
Q: What else is new with faucet technology?
A: Well, there’s been even more development when it comes to electronic faucets. People are used to going into a public restroom and doing a “faucet dance” to try and get the water from the faucet to come on. You know, waving your hands in all different directions to find that sweet spot that will start the water flow?
Well, the R&D department at Delta has been hard at work, to eliminate the “dance” once and for all.
Q: Are you telling us they have?
A: Yes, they have. It’s called Proximity Sensing Technology. And it truly is the next generation in responsive hands-free functionality. Unlike typical electronic faucets, there are no optics or infrared to maintain.
Q: No infrared? That must be where the sensing comes in?
A: Exactly. Proximity Sensing Technology transforms the entire faucet into a sensor, so that it automatically responds when approached. There’s a 4” sensing field around the body of the faucet that activates the water flow. Simply placing a hand near the faucet spout turns the water on. When hands are removed from the water stream, the faucet turns off within two seconds.
Q: Well, what happens if something gets left in the 4” sensing area? Wouldn’t that waste an inordinate amount of water?
A: If a new item like a soap dispenser or wet towel is introduced into the environment, the faucet will run for only 45 seconds before recalibrating and including the item as part of its area.
It’s important to note that this technology also contributes to water efficiency. With a flow rate of 1.5 gallons per minute, faucets with Proximity Sensing Technology can contribute to LEED® certification. Plus, you don’t have to touch the faucet to activate it, so it can help reduce the spread of germs.
Q: What powers the faucet if it isn’t light?
A: Faucets with Proximity Sensing Technology are powered by either battery or hardwire. For battery-operated models, the faucet emits an audible beep when 1500 cycles remain, indicating the batteries need to be replaced. Four C batteries last typically up to three years based on 150 uses per day. The 6-volt hardwire option eliminates the need for battery maintenance.
Q: Is it difficult to install and maintain?
Faucets with Proximity Sensing Technology require no grounding, and they’re designed to self-calibrate once they’ve been installed. A surface-mount control box makes control access easy, simplifying installation and routine facility maintenance. And, they’re backed by the industry’s best 5-year limited warranty.
Q: How is the temperature adjusted?
A: Proximity Sensing Technology uses a tempered water supply or requires the use of a mixing valve, eliminating the need for temperature adjustment and making it ideal for new or retrofit situations where tempered water is available.
Q: How many different styles of faucets have Proximity Sensing Technology?
A: Proximity Sensing Technology is available on two of the most popular Delta faucet styles: Arzo® and Grail®. Both faucet bodies are constructed of solid brass and have smart, modern designs that are highly sought after for public facilities.
