Review LOCHINVAR Fits Pressure Switch

The Lochinvar 100166162 42365-2-1121 DNS2-0600-00 42436-3-1121 Pressure Switch is a crucial component in various heating systems, designed to ensure optimal performance and safety. This pressure switch, manufactured by Lochinvar, a leading brand in commercial and industrial boiler systems, is engineered with precision and durability in mind.

The DNS2-0600-00 42436-3-1121 Pressure Switch is a Double Sealed, Non-Vacuum type, which means it is designed to operate in both high and low-pressure applications. The switch features a large, easy-to-read dial gauge, enabling users to monitor the system pressure at a glance. The dial gauge ranges from 0 to 15 PSIG, providing accurate and reliable pressure readings.

This pressure switch comes with several safety features, including a built-in temperature limiter that protects the system from overheating. It also includes a pressure relief valve, which activates when the system pressure exceeds the set limit, releasing excess pressure and preventing potential damage to the system.

The Lochinvar 100166162 42365-2-1121 DNS2-0600-00 42436-3-1121 Pressure Switch is constructed from high-quality materials, such as brass and stainless steel, ensuring durability and resistance to corrosion. The switch's compact design allows for easy installation and integration into various heating systems.

The switch operates on a simple principle: when the system pressure falls below the set limit, the diaphragm inside the switch moves, activating the contactors and initiating the call for heat. Once the pressure returns to the set level, the switch deactivates, and the system returns to standby mode.

In summary, the Lochinvar 100166162 42365-2-1121 DNS2-0600-00 42436-3-1121 Pressure Switch is a versatile and essential component in heating systems. Its large dial gauge, safety features, high-quality construction, and easy installation make it an ideal choice for professionals and DIY enthusiasts alike.
