Application

Gas sensors can be used to save significant amount of energy in enclosed facilities where automobiles or other vehicles are operated. Most facilities can reduce fan operating time and related energy costs by more than 80-95%. If variable speed drives are used to modulate fan operation additional peak load reductions of 90% or more may be possible. Paybacks can range from a few months to 2 years. Many utilities also offer rebates for these types of upgrades.

Most codes allow for ventilation based on carbon monoxide (CO) sensing. Some jurisdictions may also require nitrogen dioxide (NO2) for diesel fumes and combustibles (CG) for gas spills and vehicles powered by natural gas, propane and hydrogen. Carbon dioxide (CO2) can also be used to control strong combustion related odors in parking areas, bus garages and fire halls.

Products

AirTest offers stand alone gas transmitters, combined sensor/controllers and custom configured control systems for on/off and variable modulation of fan systems. We also offer to work with owners and contractors on system design and can offer turnkey installations.
