The Amerec AI-42 commercial steam shower generator is engineered for the most demanding commercial steam rooms with dimensions up to 2100 cubic feet (CF). The Amerec AI- series includes Two 3/4" NPT steam heads. Required control sold separately.
The Amerec AI-42 commercial steam generator can power one or two large steam baths with dimensions up to 2,100 adjusted cubic feet (ACF).
The AI-42 unit comes with an ASME-certified pressure vessel for instant steam, durable electronic components, temperature safety system, sight glass, diagnostic systems using LED lights, 3-level water sensing system with low water cutoff, and a variety of other noteworthy features.
Health clubs, day spas, hotels, and commercial wellness sites trust the powerful Amerec AI-42 commercial steam boiler for around-the-clock, automated operation. The unit features an all-steel exterior and multiple safety features which help minimize service costs and crucial downtime. Amerec AI Series generators are engineered for ease of use and easy on-site maintenance.
The AI-42 steam bath generator is UL and cUL listed and complies with ASME requirements to ensure safety and quality. All Amerec AI units are pre-tested and factory-assembled to assure that your generator is working perfectly.
The Amerec AI-42 is available in 208V three-phase (9006-423), 240V three-phase (9006-424), and 480V three-phase (9006-424) configurations.
The AI-42 requires the use of a control for operation. Controls allow facility operators to control temperature, duration, and other steam room features. Select the available control with features that best suit your preferences.
We recommend the addition of the available ADI Automatic Drain System with your AI-42 unit. The ADI Automatic Drain System performs daily draining of the boiler tank to reduce sludge and scale build-up.
