Description
The Rheem-Ruud SP15140 Low Water Cutoff is one of the essential safety devices that are incorporated in HVAC systems especially in hydronic heating systems to prevent boiler damage due to low water levels. This cutoff can work in any temperature range of 140°F-240°F and the body is made of brass material. It can take pressure of between 15 PSI and 125 PSI, and requires a water flow of at least 1.5 gallons per minute (GPM). The device works through monitoring the water level in the boiler and if the water level gets low, the burner is switched off or an alarm is produced. This essentialpart protects the boiler from any form of danger and ensures the safety of the whole heating system.
