Modular Freeze Protection Heating Systems for Metal Water Tanks

Caldor develops modular heating solutions designed to prevent water from freezing in metal water tanks and related systems.

Our systems are built with a flexible and scalable structure, allowing full customization based on customer requirements and project conditions.

Available in power ranges from 1.5 kW up to 20 kW, our solutions include both flanged and screw plug immersion heaters, ensuring compatibility with different tank designs and installation needs.

Each system is equipped with an integrated temperature maintenance and freeze protection control, keeping water above critical freezing points at all times.

For advanced applications, systems can be supplied with:

  • PLC-based control panels (optional)

  • Remote monitoring and internet connectivity (IoT ready) (optional)

  • Custom automation scenarios based on site requirements (optional)

Designed for industrial, commercial, and fire protection applications across Europe, Caldor systems ensure continuous operation, prevent system blockage, and protect critical infrastructure during cold weather conditions.
