EDAR Installation Options 

EDAR is a highly moveable Remote Sensing Device (RSD) that can be integrated into a multitude of scenarios to provide enhanced emissions-testing services. Due to its flexibility, small footprint and portable design, EDAR is adaptable to both short-term and long-term testing programs. HEAT's expert engineers have developed customized mounting systems for easy implementations to provide EDAR's remote-sensing services seamlessly and hassle-free. Many of these mounting solutions are set up with a simple push of a button. Each solution is unobtrusive to drivers and does not interrupt traffic flow or natural driving behaviors.

Due to EDAR's unique spectroscopic method of detection, it can be installed in a multitude of scenarios, even on multi-lane, high-speed roadways. This open parameter allows for an abundant number of options for installation locations, whereas traditional remote-sensing systems are limited to only single lanes. The ideal location for an EDAR system is a roadway on a slight incline with free-flowing traffic. 

Examples of How to Deploy EDAR
  • Temporary truss mount

  • Temporary trailer mount

  • Existing structures

  • New frameworks

  • Gantries

  • Bridges

  • Single poles

  • plus, many more...

EDAR Gantry Mount


EDAR Trailer Mount

Trailer System

In the United States, several jurisdictions with enhanced Inspection and Maintenance (I/M) programs must complete a 40CFR survey to meet EPA guidelines on either an annual or biennial basis. This type of study requires the collection of on-road emissions records from thousands of vehicles meeting specific criteria on a state-by-state basis. HEAT is under contract to perform these surveys in many states around North America. The company's deployment engineers accomplish the requirements of these programs swiftly and efficiently, utilizing a secure but highly movable transportable mount specially designed for temporary EDAR deployments.

The mount itself is no larger than a small boat trailer and is easily towed by a vehicle. When set in place for testing, the mount's hydraulic arm rises to over 16ft to situate EDAR at the appropriate height for data collection. When not testing, the hydraulic arm is collapsed down. The arm is raised and stowed with the simple push of a button. This particular setup enables the EDAR system to run unmanned to collect emissions data from vehicles under natural driving conditions. The commissioning of this trailer system with EDAR is a common method for various temporary applications. 

Truss System

For temporary EDAR deployments in Europe, the HEAT team utilizes a transportable truss system specifically designed to be unobtrusive and fit in the small or narrow streets typical of European cities. The truss system's compact footprint is only 1.2m x 1.2m, and the structure erects to 5.5m above the roadway. The system is easily towed to the testing location and set into place. The truss mount is simply raised by the push of a button to its complete height of 5.5 meters, as seen in the videos below.

Gantry/Bridge Mount

EDAR is a highly versatile product utilized in diverse capacities and scenarios around the world. HEAT is accustomed to addressing unique situations that need custom solutions when contracted for emissions- testing installations. The talented engineers at HEAT design, adapt and install one-of-a-kind mounting solutions to meet these needs. For example, in Belgium and Scotland, HEAT created specialized mounts to install EDAR inside gantries and on bridges for real-world emissions detection on high-speed motorways. The video below demonstrates the bridge mount.
