Heatcraft Twin Flow Unit Coolers have a compact two-way design with medium velocity airflow. The unit cooler is mounted flush to the ceiling and draws air in through the fan and discharges air out of both sides. The air pattern reduces air loss when doors are opened, and the medium velocity reduces product drying. Twin Flow units are for temperatures of 35°F and higher. Box temperatures are kept more constant throughout so your products stay fresher, longer. Seven sizes are available with BTUH from 900 to 5500 at 10° TD. Opting for EC motors gives you increased energy efficiency and cost savings.
