The Amerec AK22 is designed for home and day spa steam baths up to 900 adjusted cubic feet (ACF).

The Amerec AK22 is made up of dual generators in tandem (two 11kW generators). Each generator features a stainless-steel tank, industrial-grade heating elements, durable electronic components and parts, an electronic water level control system, and a variety of other innovative components.

Equipped with the latest technology, the Amerec AK22 steam shower generator provides the most consistent temperature and steam production. The AK22 steam unit uses a Sequential Temperature which ensures an even, consistent flow of soft steam.

Amerec AK Series generators are engineered to deliver years of exceptional performance and reliable operation. The AK22 steamer’s durable stainless-steel tank and water level probes provide long-lasting strength and durability. The unit includes removable heating elements for easy and economical service.

The compact Amerec AK22 steam shower unit installs conveniently out of sight in closets, vanities, cabinets, and other similar locations.

Homeowners and day spas rely on Amerec AK Series steam room generators for low cost, safety, and dependability.

The Amerec AK22 22kW steam generator is available in 240V (9012-220) or 208V (9012-221) and can be field wired for single-phase or three-phase configurations.

The AK22 steam bath generator requires the use of the available K3 control for operation which regulate bathing duration and temperature, or the R30K 30-minute timer. Each control package includes a matching finish ComfortFlo steam head.

Amerec AK Series steam room generators can be linked in tandem to accommodate steam showers larger than 900 adjusted cubic feet. Connection cables are sold separately, and each generator requires a ComfortFlo steam head.

We recommend purchasing Amerec’s Automatic Drain System for each steam generator with your AK22 which drains each steam generator tank after each use to help prevent calcification and lime build-up.

The Amerec AK-22 generator carries a limited lifetime warranty and is fully serviceable. Amerec AK residential steam room generators are UL, CSA, and CE listed for your safety.
