CST™ Continuous Steam Technology The ONE Plus™ steam cleaner was designed with a two-tank system. This technology means the water tank is not under pressure and can be refilled at any time eliminating downtime. Stainless steel boiler High-grade stainless steel is TIG welded together with a robotic welder to ensure the quality of the most solid and durable boiler on the market. This is why Dupray provides a lifetime warranty on its boilers – the heart of any steam cleaner.
Automatic shut-off The heating element will automatically shut off when the water level drops below the minimum threshold. Your steam cleaner is instantly ready to go once you refill the water tank. ActiveSafe™ Four levels of safety ensure that your steam cleaner will always operate safely. These levels include the low water light the automatic shut-off a pressurized safety cap with a built-in blowoff valve and a childproof safety lock.
Superheated dry vapor The Dupray ONE™ steam cleaner produces the perfect steam. Its stainless steel boiler is pressurized to 4 times the atmospheric pressure to increase the boiling point of water to 293ºF / 145ºC. The high-density heating element then superheats the steam to 303°F / 150°C resulting in a low-moisture vapor steam with only 5% water content. Steam at this level is an ideal combination of water content temperature and pressure.
