Liebert 100075S Fusible Plug Safety Device for Refrigeration Systems

The Liebert 100075S is a genuine OEM fusible plug designed as a critical safety device for Liebert refrigeration and HVAC systems. This temperature-activated pressure relief component provides essential protection for refrigerant receivers, condensers, and other pressurized vessels in commercial cooling applications.

How It Works:

Unlike standard pressure relief valves that respond to internal pressure, this fusible plug operates based on temperature. The device contains a low-temperature alloy element that melts when exposed to excessive heat, creating a controlled pressure relief path. This prevents catastrophic vessel failure in the event of fire, system overload, or other emergency high-temperature conditions.

Key Features:

• Genuine Liebert OEM replacement part (MPN: 100075S)
• Temperature-activated safety relief mechanism
• Protects refrigerant receivers and pressurized vessels from over-pressure conditions
• Designed for use with Liebert DSE, PDX, PCW, and other commercial cooling systems
• Threaded design for secure installation
• Prevents system damage and potential explosions during fire or overheat events
• Meets ASHRAE 15 safety code requirements

Applications:

This fusible plug is commonly used in Liebert precision cooling systems, data center air conditioning units, and commercial refrigeration equipment. It is typically installed on refrigerant receivers, condensers with integral receivers, or other closed vessels that require pressure relief protection per local building codes.

Essential replacement component for maintaining system safety and compliance in commercial HVAC and refrigeration applications.
