The Sarape CVHB is designed to be a simple solution for adding freeze protection to exposed control valves. With a modular design and adjustable stabilization legs, the boxes can easily be deployed or removed as needed.

The CVHB boxes are industrial grade and fabricated with extreme wear-resistant materials for outdoor waterproof service in corrosive areas. They operate on 120 VAC power and have an FM approved bi-metallic thermostat sensing ambient temperature to automatically engage the heating box within a certain temperature range.
