Freeze Protection

Freeze Protection Heating Systems for Water Tanks in Fire Suppression Systems


Caldor manufactures a complete range of electric freeze protection heaters specifically designed for water storage tanks and piping systems used in fire suppression installations. These systems ensure the optimal performance of fire safety equipment even under extreme winter conditions, by preventing water from freezing and the system from becoming blocked.

Electric Heating Cable Solutions for Freeze Protection in Fire Suppression Water Tanks

Freeze protection is essential for water storage tanks and piping systems used in fire suppression installations, ensuring reliable system operation even under extreme winter conditions by preventing water from freezing and blocking the system. These solutions are engineered for continuous protection, operational safety, and simplified control in low-temperature environments.

Electric heating cable systems deliver controlled heat directly to tank walls, inlet/outlet piping, and critical components. They operate efficiently at low surface temperatures and are designed to maintain fluid temperature above freezing without the need for high temperature outputs. This makes them especially suitable for fire protection water tanks, remote installations, or facilities with limited power availability.

Key technical and functional characteristics include optimized power ratings tailored to tank size and heat loss characteristics, corrosion-resistant components, robust environmental enclosures, and integrated control options that activate heating automatically when ambient temperatures drop below predefined thresholds.

Electric freeze protection cable systems can be configured with a range of control and monitoring options — from simple thermostatic activation to advanced panel-mounted or computerized controllers — ensuring precise temperature maintenance and improved system reliability.

These systems are widely applied in industrial, commercial, and logistical facilities where freeze protection of fire suppression water tanks is critical, including power plants, warehouses, manufacturing plants, and commercial buildings.
