PROFESSIONAL BOILER UNIT The all new 4000BU is the newest entry in our line-up of professional steam boiler units. The 4000BU establishes a new benchmark for features, ease of use, quality of components and value.

IT’S ALL ABOUT THE STEAM  The 4000BU excels at producing quality, dry, pressurized steam. Pressurized steam is the fastest and most efficient way of ironing. It allows the fibers of the fabric to be softened quicker, with the weight and heat of the iron laying the fibers down flat. This creates the crisp and clean finish demanded by professionals.

LIFETIME GUARANTEE  Lifetime product warranty policy applies to all Reliable Corporation pressurized steam boiler tanks. See warranty document for details.

THERMOSTAT RESET BUTTON  Say goodbye to burnt out heating elements. The thermostat reset system is the ultimate protection for your investment, automatically shutting-off the heating element when the water is low.

4 SAFETY SYSTEMS  The 4000BU has 4 safety systems including a pressure switch, probe safety thermostat on the heating element, safety cap with safety valve, and a low water indicator.

ADJUSTABLE STEAM VALVE  The 4000BU is equipped with a convenient valve that allows you to control the exact amount of steam that is required for the job.

CARRYING HANDLES  The 4000BU’s carrying handles are conveniently placed on both sides of the boiler unit to allow for safe transportation when necessary.

ACCESSORY KIT  Each 4000BU steam boiler unit comes complete with a water funnel, iron cord support and a water level measurement stick.

MADE IN ITALY  Made in Italy with strict attention to quality components and construction. Designed to please aesthetically and to go beyond expectations for performance.
