Warehouses come in many shapes and sizes, some automated, some manual, some a combination of both. Depending on the specific application, they may require precise climate (such as temperature and humidity) control, scheduling for occupied and unoccupied modes, or an OA/RA design to cut energy costs while keeping the space warm. AbsolutAire can provide a specific solution to any warehouse application.

The patented AbsolutAire E-Series direct-fired air turnover unit offers a unique and economical alternative to the typical, 80% efficient indirect-fired air turnover system commonly used in warehouses. The 99.97% efficient direct-fired burner coupled with the “air turnover” design ensures uniform heating without stratification. The E-Series mixes warm building air with as little as 2% OA to heat the space, all while using a high performance, direct drive axial fan to keep energy costs low.

Conserving precious floor space is just as important as conserving energy in a warehouse application, and AbsolutAire has several outdoor-mounted options to meet these needs. These units can also combine a mix of OA and RA to slash heating costs. AbsolutAire has pioneered an economical, high-efficiency space heating system using a direct-fired burner and a high volume, low velocity air recirculation approach. This unique combination ensures that direct-fired gas heating systems are considerably less costly to operate than other heating systems. With a wide range of airflow and heating capacities, modular design, and many options and accessories available, AbsolutAire space heating systems are the perfect solution for both new and retrofit construction.
