Interface solutions for the pool, spa, and whirlpool industry.
Pool and spa controls fail. Moisture delaminates membrane overlays. Steam triggers capacitive panels. Mechanical switches leak underwater. RNC solid-state technology operates fully sealed across every wet surface: in-pool counter-current jets, hot-tub and spa controls, outdoor water play, and underwater lighting.
What pool and spa controls face.
The interface is the most replaced component in most spa systems. That replacement cycle is the problem RNC's technology eliminates.
Specify the surface. Same engineering underneath.
The piezo sensing layer works through any cover material. Choose the surface to fit the application: tempered glass for premium consumer products, polycarbonate for impact and weight, stainless for commercial installs, acrylic or composite to spec.
Same OEM platform. One firmware. Material decided at design phase.
The topside is the spa industry's biggest service issue.
In a hot tub or spa, the topside panel is the user's only interface. It lives under wet hands, steam, and chemical-treated water for the product's whole life. And it's the component that fails first. Three dominant technologies, each a compromise.
Moisture migrates through the overlay. Buttons go unresponsive. Replacement every 2-3 years.
Ghost-triggers from droplets and steam. Unresponsive with wet hands. Sensitivity drifts in humidity.
Sticks, leaks, no LED feedback, no programmable behaviour. Each button needs its own air tube.
Pool automation and commercial facility controls.
Pool automation controllers manage filtration, heating, chlorination, lighting, pumps, and water features. The control panel is the product. It sits outdoors or in a pump room, exposed to splash, humidity, chemical fumes, and UV.
Commercial aquatic facilities add public use volumes, vandalism, and regulatory requirements. The interface must survive the chemical environment and deliver reliable operation across a product lifecycle measured in decades, not years.
Counter-current, lighting, and in-pool activation.
Counter-current systems, swim-jet controls, underwater lighting, and in-pool activation points must operate fully submerged in chemically treated water. This is the most demanding application for any control interface.
Conventional switches rely on shaft seals and O-rings that degrade from chemical exposure and thermal cycling. There is no maintenance access underwater.
No seal to degrade
Continuous solid metal, glass, or polycarbonate. There is no seal because there is nothing to seal.
IP69K. Tested to 300 m.
Potted construction prevents the thermal-shock cracking that hollow-cavity switches experience.
LED feedback underwater
Programmable colour, intensity and behaviour, visible through the control surface.
Water features, fountains, and interactive play.
Splash pads, play fountains, and public water feature installations need controls that survive outdoor exposure, continuous water contact, and sustained use by children and the public.
No membrane to fail
Solid metal, glass, or polycarbonate. Nothing to delaminate, nothing for moisture to penetrate.
Works fully submerged
IP69K sealed. Withstands chlorine, bromine, ozone, and all pool chemicals.
Senses through the surface
Stainless, glass, polycarbonate, acrylic. The material in the water is the control surface.
One cable, all functions
PT Plus consolidates 6-8 functions onto a single cable. Simpler assembly, fewer errors.
LED illumination built in
Visual feedback through the control surface, above and below water. Colour and behaviour programmable.
50M+ activations
Outlasts the product it is built into. No replacement cycle, fewer warranty claims.
RNC piezo panels and switches are in development and deployment with European spa and pool equipment manufacturers, providing solid-state controls and individual switching points that eliminate the membrane failure mode and simplify wiring architecture. Underwater piezo switches are deployed in counter-current and pool lighting installations, operating fully submerged in chemically treated water with zero seal-related failures.
