Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the building envelope. High temperature and humidity levels can also increase concentrations of some pollutants. If too little outdoor air enters a home, pollutants can accumulate to levels that can pose health and comfort problems.

The concern over Indoor Air Quality (IAQ) is gathering momentum in recent past by the users of commercial as well as residential buildings and the users are keen to maintain better IAQ inside their working space. As the ambient fresh air is at adverse condition compare to indoor air, treating this fresh air is a must-have accessory with conventional air-conditioned systems.

The energy usage for treating fresh air is concern for the building owner and there is strong demand for energy recovery based TFA systems globally. For most of the old centrally air-conditioned buildings either such systems are deployed or there is no heat-recovery unit to save energy wasted in the process. While for hospital, hotel and other commercial buildings, TFAs are supposed to run 24/7 to ensure acceptable IAQ energy usage is point of concern.

Toro TFA product line, being an energy efficient enthalpy recovery solution, can save 80% or more energy and reduce the chiller size. Toro TFA uses highly energy efficient corrosion free, En3 (Energy Cube) sensible Heat exchangers. The heat exchangers operate in heat recovery mode and treat out-door air by removing both sensible and latent heat.

Toro TFA is 100% fresh air-cooling system that is cost effective and maintenance free.
Toro TFA is an exceptional design for fully integrated air-to-air heat recovery, it saves 60% to 85% energy compared to conventional TFA and has a faster pay back compared to all other forms of energy and heat recovery units.
