The VairTEX™ Air Director improves condenser airflow on suitable commercial HVAC and refrigeration equipment. This passive retrofit supports heat rejection with no added power and no moving parts.
Simple. Efficient. Sustainable.

The business case
Lower operating costs.
A practical path to adoption.
A targeted upgrade to airflow, designed around suitable equipment already serving your business.
Reduce cooling energy use
Improve airflow at the condenser so your system can reject heat more effectively.
Support cooling performance
Direct hot discharge air away from the unit and help reduce recirculation, particularly when equipment is working hard in warm conditions.
Put existing assets to better use
Make a targeted efficiency investment in suitable equipment already in service, with installation planned around your site’s operations.
Scale to suit your facilities
Start with one location, then roll out across suitable equipment and additional sites at a pace that fits your business.
Evidence, with context
Results from operating sites.
Three installations.
Three clearly identified performance measures.
Average measured RTU
power reduction
Testing recorded a 16.94% average reduction in rooftop-unit power, with a highest measured reduction of 21.05%.
Lower average recorded
compressor load
Condenser C recorded 22.1% lower average compressor load in June–July 2023 compared with June–July 2022.
Normalized annual RTU
energy savings
The Dilfo measurement and verification case reported 16.7% normalized annual rooftop-unit energy savings at one installation.
Results relate to the equipment and conditions studied; project performance varies. These are distinct performance measures, not directly comparable savings guarantees.
