For many years Indirect-Fired Air Turnover Units (ATU) were the standard for commercial and industrial facilities. However, they have begun to phase-out in favor of Direct-Fired Fixed Return Handlers (DFFR) due to the many distinct advantages over ATU:
DFFR Advantages
- Lower Upfront Cost: DFFR initial cost is LESS than or equal to that of ATU
- Greater Energy Efficiency: DFFR gas heating efficiency is 20% higher than ATU
- Mounting Flexibility: DFFR can be mounted anywhere, unlike ATU, freeing valuable floor space
- Improved Comfort & IAQ: DFFR provides outdoor air which reduces cold drafts and enhances indoor air quality, unlike one-dimensional ATU
As a leader in manufacturing Direct-Fired Air-Handling Units, Rapid Engineering air handlers are an attractive option for facilities looking to upgrade their indoor air quality and save money in the process.
