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
- 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.
sensors use electrical conductivity measurements, surface temperature,
and optical measurements to monitor roadway surface conditions.
Automatic Anti Icing System Activation
Parapet Mounted Nozzle
A computer algorithm uses the data to calculate when icing conditions
will occur and activates the system before the road ices. A computer
logs the event conditions, date, and time.
Allows remote site monitoring and activation of FreezeFree anti
icing liquid spray system.
System Performance Monitoring
Alerts maintenance personnel when reservoir contents are low or
other servicing is required.
Expandable to Any Road Width
in-pavement nozzles in stainless steel and acetal housing can spray from
the middle of the road, replacing or supplementing standard wall-mounted
nozzles to supply 4 to 6 lane roads. Can also be expanded to 3000
m (10,000') in length.
Remote Manual Override
personnel can activate/de-activate and configure the spray system
based on local conditions through any computer connected to
When used in conjunction with SSI's RWIS, maintenance personnel
can visually access roadway conditions of remote sites.
