Application

Model BTO is ideal for temperatures of 35°F and higher. Box temperatures are kept more constant throughout and fresh products last longer. Seven sizes are available with BTUH from 900 to 5,500 at 10° TD.

Larger BTO sizes are suitable for large reach-in and small step-in or walk-in coolers.
