Overview
The Energy Absorption Systems, Inc. FreezeFree System utilizes Fixed Anti-Icing Spray Technology (FAST) to deliver anti-icing agents that prevent snow, ice and frost from forming a bond to a road surface. The FreezeFree System consists of a pump house assembly containing a holding tank, an electrical pumping system and a computer-based controller. Conduits carry power, communications, and chemicals to a number of valve box assemblies that control delivery of the material to spray nozzles strategically placed throughout the system. Flexible design allows the FreezeFree to be activated in a number of ways:
- On-site via push button.
- Remotely through phone or PC link.
- Automatically using active and passive sensors or an integrated Road Weather Information System (RWIS).
Additionally, The FreezeFree System is scalable in size and can cover multiple lanes of traffic using flush and side-mount spray nozzles. Multiple mounting options for components such as valve box assemblies and spray nozzles allow for system customization and easy installation.
