HAGER ENVIRONMENTAL AND ATMOSPHERIC TECHNOLOGIES (HEAT EU) LIMITED

Hager Environmental & Atmospheric Technologies (HEAT EU) Limited is a pioneering clean‑air specialist that has turned NASA‑spun‑off laser technology into a practical, touch‑free emissions‑testing solution. Their flagship Emission Detection and Reporting (EDAR) system uses eye‑safe, infrared‑laser spectroscopy to remotely sense the infrared absorption of a wide range of gases directly from the tailpipe of a moving vehicle, whether on a single lane or a multi‑lane highway.

The EDAR unit operates unattended, 24 hours a day, seven days a week, and requires no on‑site calibration. By employing the Differential Absorption Lidar (DiAL) method it quantifies gases such as CO, CO₂, NO, NO₂, NOₓ, total and speciated hydrocarbons, particulate matter and virtually any gaseous molecule, while simultaneously measuring exhaust temperature to distinguish cold‑start emissions from genuine high emitters. Results are delivered in grams per kilogram of fuel, parts‑per‑million, ratios and grams per kilometre or mile, providing cities and regulators with real‑world, high‑resolution data to guide smart, evidence‑based air‑quality policies.

HEAT EU’s remote‑sensing technology therefore offers a safe, accurate and continuous way to monitor vehicle emissions across the United States, Europe and beyond, supporting municipalities and environmental programmes in their quest for cleaner, healthier air.
