Liquid Expansion Trap Provides Freeze Protection

May 13, 2014
Compact trap offers last line of defense against pipe freezing.

Spirax Sarco has released the new compact, easy-to-install Bydrain freeze protection liquid expansion trap. Designed as a last line of defense against pipe freezing, the trap may prevent loss in production, repair costs and possible safety hazards.

The Bydrain can be installed on or downstream of the equipment to be drained, ensuring that it is accessible for inspection and maintenance. The trap is placed at the end of pipes, at low points or in any area where liquid could be stationary and susceptible to freezing.

The stainless steel, fixed temperature discharge trap continuously monitors the temperature in the pipes. As the temperature of the liquid cools to 36°F, the trap opens, discharging any liquid in the pipe.

Bydrain trap applications include freeze protection for float and thermostatic steam traps, coils, tanks, water lines on docks, eyewash stations, safety showers, tracing condensate manifolds, condensate return lines, pressure powered pumps, electric pumps and flash tanks.
