Vehicle Exhaust Systems - Why Install a gas detection system?

Safety – The solution to pollution is dilution. The solution to vehicle exhaust in parking garages is dilution with “fresh” air drawn in by fans, louvers and doors until reaching an acceptable gas concentration. Macurco gas detectors provide automatic exhaust fan control to help maintain acceptable levels of Carbon Monoxide (CO), Combustible Gases (EX) or Nitrogen Dioxide (NO2) in parking garages. Consult local codes for the specific requirements.

Savings – When people think about sustainability and saving energy, the temptation is to think first of inhabited spaces like offices and residences, but one of the most important areas is in reducing energy consumption in enclosed parking garages. Installing ventilation controllers based on gas concentrations can substantially reduce consumption of both electricity and natural gas and pay for itself in less than one year

Silence – In residential facilities like condominiums with enclosed parking, the noise from exhaust fans can negatively impact tenant satisfaction. Noise pollution adversely affects the lives of millions of people. Studies have shown that there are direct links between noise and health. Problems related to noise include stress related illnesses, high blood pressure, speech interference, hearing loss, sleep disruption, and lost productivity.
