Consider the following questions concerning freeze protection:

1. Which systems use water in your facility? Water supply lines, condensate systems, piping, and safety showers probably come to mind.

2. What happens if those systems freeze? Interrupted systems, overheated equipment, and dangerous working conditions are all possible.

If water-bearing systems are left unprotected, a cold front could make these worst-case scenarios a reality. Even heat-traced systems are at risk should their electric tracing malfunction. 

To ensure that your equipment and processes remain operational all winter long, consider implementing the HAT/FP automatic freeze protection valve. 

Prevent Freezing with the HAT/FP Valve

The self-modulating HAT/FP freeze protection valve eliminates manual freeze valves and the expensive human error associated with their operation. Reliable and accurate, this valve automatically opens on falling temperatures to drain cooled water and prevent critical systems from freezing. 

Systems Most Likely To Freeze:

Outdoor Cold-Water Supply Lines

When a naval ship is dry-docked with equipment on board that requires a constant water supply to function, outdoor cold-water supply lines are connected from the dock to the ship. As these lines are exposed to the elements, they are frequently in danger of freezing. Manual freeze protection valves often result in an expensive waste of water when left open to drain long after the danger has passed due to human error.

The HAT/FP valve discharges only the minimum amount of water needed to prevent the line from freezing, therefore eliminating human error, reducing energy consumption, and often resulting in significant utility savings.

Condensate Systems & Float Traps

Various processes and systems contain condensate, either as a primary material or as a by-product, which is susceptible to freezing in the winter months.
The HAT/FP is installed at the end of a condensate line, often in place of a traditional steam trap. Once the condensate temperature falls to the valve’s set-point, it will open and drain the line before a freeze can occur.

Safety Showers on Military Bases and in Government Facilities

Emergency safety showers and eyewash stations’ water lines are often left unprotected, making frigid temperatures especially dangerous when harmful chemicals are being handled on military bases or in government facilities. The HAT/FP valve is installed at the emergency shower’s lowest point to drain cooled water before it can freeze and compromise the safety fixtures.
