DFE Specifications
Overview
The dual discharge DFE range has been specifically designed for cold rooms with limited height for the preservation of fresh or frozen products and in food preparation and handling.
Range consists of 12 customizable models.
According to the room temperature, the range is divided as follows:
- DFE H3 for higher temperatures (≥ 2 °C) with 3,5 mm fin spacing
- DFE L7 for lower temperatures (≥ –25 °C) with 7 mm fin spacing, electric defrost version (ED) is recommended
On request, the models can be equipped with non-standard: coils, defrosting, and fan motors.
Coil Features
The entire range is equipped with high efficiency coils made from special profile aluminium fins and inner grooved copper tube, suitable for new generation refrigerants (smooth tube for brine coolers).
Casing
