Bydrain Freeze Protection Liquid Expansion Trap
The compact, easy-to-install bydrain freeze protection liquid expansion trap from Spirax Sarco is designed as a low cost, last line of defense against pipe freezing, preventing loss in production, repair cost and possibly safety hazards. The bydrain can be installed on the equipment or downstream of the equipment to be drained, ensuring that it is easily accessible for inspection and maintenance. Placed at the end of pipes, at low points, or any area where liquid could be stationary and thus susceptible to freezing. This trap is made of stainless steel material and is a fixed temperature discharge trap that continuously monitors the temperature in the pipes; the trap is firmly closed at 45 F, but as the temperature of the liquid cools to 36 F the trap opens, discharging any liquid in the pipe.
Typical Applications for this trap 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.
