AK Series 11KW Steam Shower Generator

The Amerec AK11 is designed for home and day spa steam baths with dimensions up to 375 adjusted cubic feet (ACF).

The AK11 steam shower generator includes a durable stainless-steel tank, industrial-grade heating elements, durable electronic components, an electronic water level control system, and a variety of other noteworthy features.

When engineering this generator, Amerec focused on ensuring the most consistent steam production and temperature for a satisfying steam bath. The AK11 steamer uses a Sequential Temperature Control to ensure a consistent and even flow of soft steam.

Amerec AK Series steam generators are built to power the most demanding home and commercial steam rooms. The AK11's stainless-steel tank and water level probes provide years of reliable, trouble-free operation. The AK11 steam shower unit is equipped with removable heating elements for easy and economical service.

The compact size of the AK11 steam unit installs conveniently out of sight in closets, vanities, cabinets, and other similar locations for your convenience.

The Amerec AK11 11kW steam bath generator is available in 240VĀ  or 208V and can be field wired for single-phase or three-phase configurations.

The AK11 generator requires the available K3 control for operation, which regulates bathing duration and temperature, or the R30K 30-minute timer. Each control package comes complete with a matching finish ComfortFlo steam head.

Amerec AK series generators have the flexibility to be linked in tandem to accommodate steam rooms larger than 550 adjusted cubic feet to meet all your steam shower size needs. Connection cables are sold separately, and each generator requires a ComfortFlo steam head.

We recommend the available Amerec Automatic Drain System with your AK11 generator. The Auto Drain System automatically drains the steam generator tank after each use to prevent calcification and lime build-up and ensure the optimal performance of the unit.

The Amerec AK-11 generator carries a limited lifetime warranty and is fully serviceable. Amerec AK Series steam room generators are UL, CSA, and CE listed to ensure your safety.

Health clubs, day spas, and homeowners rely on Amerec AK residential steam shower generators for low cost, efficiency, and durability.
