AK Residential Generator Series: Creating the Ultimate Steam Bath Environment

McCoy's AK generators set themselves apart from other residential generators with several unique features.

"Soft Steam" function maintains the ultimate comfort zone. Minimal temperature variations and an even flow of steam are the two most important traits of the perfect steambath. McCoy's engineering provides both traits with its unique "soft steam" function. The AK generator features innovative "soft steam" element switching to maintain a consistent and comfortable steambath environment. The AK uses full power to quickly heat up the steamroom to its preset temperature; then cuts power to half its elements, resulting in a more consistent flow of soft billowing steam and more stable temperature. "Soft Steam" functions only with K30, KT60, and K60 controls (not with R30K).

McCoy Residential Steam Generators and Controls – the New Industry Standard.

The single factor most greatly affecting steam bathing comfort is minimal temperature fluctuations. Comparative testing proves the superior performance with the "soft steam" element switching, a feature exclusive to the AK generator.

K200i Freedom Control

The innovative K200i Freedom Control from Amerec provides the ultimate steam bathing experience. The wireless remote control allows the bather to operate control functions from virtually anywhere within 50' of the steam shower.

Installation is simplified as there is no need to run control cables inside shower walls or drill large holes through expensive marble, granite or tile wall material.

Available options for the K200i Freedom Control:

  • Chromatherapy Lighting
  • Fragrance Injector
  • EvenSteam Air Circulation Fan
  • Warm Start, instant steam feature
K60, K30, KT60 and R30K Steam generator controls

The AK generators now feature five control options: The K60 and KT60 have a three button panel with on/off, temperature setting and time setting which can be adjusted up to 60 minutes. The digital display alternately shows room temperature and time remaining. The display window of the K30 lights up when the generator is on. Both the K60 and the K30 have remotely located thermostats.

AK Control Features
  • K60 and K30 can be mounted inside or outside the steambath
  • KT60 has a built in thermostat for easier installation and must be mounted INSIDE the steambath
  • R30K is a simple on/off switch with a built-in 30 minute timer, and may be mounted inside or outside the steambath
