The Mr.Steam CU-HTC is a high temperature limit device for CT and CU commercial steam generator systems — the independent backstop that shuts steam down if the room ever exceeds safe temperature, regardless of what the main control is doing.
Redundant temperature protection is standard practice in commercial steam installations: the operating control manages the target temperature, and the high-limit device sits above it as a fail-safe, providing temperature shutoff and alarm functions if that ceiling is ever crossed. The CU-HTC works with any Mr.Steam CT or CU steam generator system and integrates with the CU Alarm for audible notification.
If you’re building out a club, spa or hotel steam room on Mr.Steam commercial equipment, this device belongs in the spec alongside the SteamStop switch and CU Alarm.

Types of Mr. Steam Generators
CX - Commercial Steam Generator Series
The Mr. Steam CX Commercial Steam Series is a commercial-grade steam generator system designed for heavy-duty use in hotels, spas, health clubs, fitness centers, and other facilities where steam rooms operate for extended periods throughout the day. Unlike residential steam generators, the CX Series is built for continuous operation and includes commercial features such as stainless-steel construction, electronic water-level controls, automatic flushing to reduce mineral buildup, and advanced safety protections.
The CX lineup ranges from the CX0360 for steam rooms up to 360 cubic feet to the CX5000 for rooms as large as 5,000 cubic feet. Each system includes a commercial touchscreen controller that allows facility operators to schedule operating hours, monitor system performance, and manage multiple generators as a single integrated system. For larger steam rooms, multiple generator modules are linked together to provide the required steam output while maintaining reliability and efficiency.
MSSUPER Steam Generator
The Mr. Steam MSSUPER Series is part of Mr. Steam's residential steam generator lineup and is designed for larger home steam showers that require more steam output than the standard MS90–MS400 models. The MSSUPER models are typically used in larger residential steam rooms, luxury primary bathrooms, and custom spa-style installations.he generators can be installed up to 60 feet away from the steam shower in locations such as closets, cabinets, insulated attics, or under benches, making them flexible for custom home designs.
MX-R Steam Generator
The Mr. Steam MX-R Series is the largest and most powerful residential steam generator line offered by Mr. Steam. Designed for large luxury steam showers and residential steam rooms, the MX-R models are available in 20kW, 24kW, and 30kW capacities, covering steam rooms from approximately 483 to 964 adjusted cubic feet. They feature the same premium Mr. Steam technology found in the standard residential line, including a stainless-steel tank, industrial-grade heating elements, SteamIQ microprocessor controls, self-diagnostics, and compatibility with all Mr. Steam controls and spa accessories.
The key distinction is that the MAX Series fills the gap between the MSSUPER residential generators and the commercial CX Series. While the MX-R is capable of handling very large home steam rooms and some light commercial/day-spa applications, Mr. Steam officially classifies the MAX Series as a residential-use generator. For facilities with continuous daily operation such as hotels, gyms, and commercial spas, the CX Series remains the recommended solution.
MS-R Steam Generator
The Mr. Steam MS Series (MS90–MS400) is Mr. Steam's core residential steam generator lineup and is designed for standard home steam showers. These generators are ideal for steam rooms ranging from approximately 100 to 257 adjusted cubic feet, making them the most common choice for residential bathroom steam shower projects. The series includes models such as the MS90, MS150, MS225, and MS400, allowing homeowners to select the appropriate generator based on the size of their steam room.
