Johnson Controls has announced the release of its UL Certified TYCO® LFP™ Antifreeze. This third-party tested and evaluated solution helps fire protection systems comply with National Fire Protection Association (NFPA) 13, 13R, and 13D, which require the use of listed solutions in new antifreeze systems. Existing antifreeze systems must meet this requirement by 2022 under NFPA 25.
A. O. Smith introduced the Product Preservers™ Powered Anode System. The new anodes, which are designed to provide maintenance-free protection for all water types, are available as an upgrade to replace the sacrificial anodes that come as industry standard equipment on tank-style heaters.
Kohler is introducing three new industrial light commercial generator models for stationary emergency applications. The Kohler 25CCL, 30CCL, and 36CCL are 60-Hz generators, which can be fueled by either natural gas or liquid propane and integrate the Kohler APM402 controller as well as a Kohler 2.2-liter turbocharged engine. According to officials, the new generators provide advanced voltage and frequency regulation along with ultra-low levels of harmonic distortion for power quality and enhanced protection for sensitive, valuable electronics.
Seresco USA Inc. has introduced the Natatorium Ventilation (NV)-Series. The company says it is the industry’s most efficient and non-compressorized ventilation system for conditioning natatorium environments with outdoor air and heat recovery, but without compromising IAQ.
Power management company Eaton announced the launch of its heavy duty safety switches with surge protection, the latest in its portfolio of switching devices.
