Therm-Omega-Tech’s GURU Plugs were developed expressly for fixed volume applications. When the engine is running, the warm water passing by the valve keeps the valve shut. After the engine shuts down, the whole system cools. Before the series of small tubes in the system can freeze, the water sensing qualities of the GURU Plug cause it to snap open. This will drain the whole system rapidly before any freeze can occur. This snap acting valve must be used because there is no source of warmer water to purge the system, as there is in the re-supply system. By installing the valve at the lowest point in the system, complete drainage is ensured.

Guru DL 2.1 Series

• Easy installation
• Completely mechanical - No electrical or air connections
• Not affected by air flow or air temperature surrounding valve
• Rapid draining
• Easy system refill

Magnum Guru Series

• Drains twice as fast as the standard GURU Plug
• Easy installation, field testing & maintenance and system refill
• Completely mechanical - No electrical or air connections
• Not affected by air flow or air temperature surrounding valve - releases only when cooling water reaches setpoint
• Hex body/cartridge assembly on Magnum types T and FL can be maintained or replaced without draining cooling system

Passenger Car Freeze Protection

IC/FP (Freeze Protection) valves sensitivity to water temperature makes this valve ideal for applications where water conservation or wastewater disposal are a prime concern.
