When the temperature outside drops, it adversely affects the water flowing through your equipment. With Speakman heat traced combination emergency shower & eye/face washes, we’ve designed a revolutionary interior that is wrapped with our signature cable, insulated with rubber foam and protected with an PVC plastic shell to keep the unit from freezing, even to temperatures as low as -50°F. The emergency stations feature a high performance emergency shower head and eye/face wash. The Freeze protection valve, activated automatically below 40°F and protects the unit from freezing in the event of a power outage. Speakman heat traced combination emergency stations are ANSI/ISEA Z358.1 approved & OSHA compliant.
