Trojan Cool Touch Kit, 3/4 For C/D Uts

The Trojan Cool Touch kit, sized for 3/4" connections and intended for use with C and D units, adds an important and often overlooked layer of thermal safety to ultraviolet disinfection systems. At the heart of the kit is a heat-sensitive pressure relief valve designed to protect the UV chamber in the specific situation where water flow stops while the UV lamp remains energized and continues to generate heat.

Understanding why this matters helps explain its value. If water sits stagnant inside an operating UV chamber, for instance when no fixtures are drawing water but the system remains powered, the heat radiated by the lamp can raise the temperature of that trapped water quite significantly. Without protection, the next person to open a tap could be met with an unexpected slug of very hot water, and the elevated temperature can also stress system components. The Cool Touch valve continuously monitors the chamber temperature, and when that temperature exceeds a pre-set threshold, the valve automatically opens to drain the hot water out of the chamber. This prevents excessive heat buildup, protecting the equipment and helping to guard against the risk of scalding when flow eventually resumes.

• Cool Touch kit with 3/4" connections for C and D UV units
• Heat-sensitive pressure relief valve included
• Opens automatically to drain the chamber when temperature exceeds a preset point
• Helps protect UV system components from overheating during no-flow periods
• Improves overall safety of the UV installation
• Weighs approximately 0.72 lbs

For installations where water may sit idle in the UV chamber for stretches of time, such as cabins, seasonal or vacation homes, and any system with intermittent or low-frequency water use, a thermal relief accessory like this provides valuable peace of mind and meaningful protection. It complements the routine maintenance that every UV system requires, including annual lamp replacement and periodic cleaning of the quartz sleeve. Always follow the manufacturer's instructions for the proper placement, plumbing, and discharge routing of the Cool Touch valve within your specific system. Routing the valve's discharge to a suitable drain ensures that any released hot water is safely carried away rather than creating a mess or hazard near the equipment, and adding this thermal safeguard is a small, sensible investment that protects both the UV system and the people who use the water, particularly in homes where long no-flow periods are a regular part of the usage pattern.
