In warmer months, the sun can easily overheat external water carrying pipes, resulting in emergency safety showers and face/eyewash stations being supplied with dangerously hot scalding water.
Even facilities with exclusively internal water carrying pipes are at risk of having water overheated by malfunctioning steam or electric pipe tracing systems.
While potentially scalding water being delivered through emergency fixtures is a safety hazard by itself, hot water above 100°F (37.8°C) may also cause an exacerbated chemical reaction.
To avoid scalding or a dangerous chemical reaction, the HAT/SP scald protection valve monitors and drains overheated water from safety stations to protect workers.
Installed in-line, the HAT/SP monitors ambient or fluid temperatures. When the valve’s internal thermostatic actuator senses that the temperature has reached 98°F (36.7°C), the valve will automatically modulate open and drain. Once the back-filling water temperature has fallen to 95°F (35°C), the valve closes to conserve water.
HAT/SP Scald Protection Valve
Designed and manufactured in the USA, the HAT/SP functions mechanically and does not require a source of electricity to operate.
