Dry barrel fire hydrants are essential components of fire protection systems in cold climates, where the risk of water freezing in the hydrant barrel is a concern. They are specifically engineered to keep water out of the upper barrel until the hydrant is activated, ensuring reliable operation even in freezing temperatures.
- Designed to keep water below frost line until use
- Commonly used in municipal, industrial, and refinery fire protection networks
- Rugged ductile iron construction, epoxy coating, and flanged Compliant with AWWA C502 or equivalent international standards
