TEFCOLD Monoblock Freezing Unit WRA-L11-1 for Cold Rooms

A monoblock freezing unit removes heat from a cold room by circulating refrigerant through a closed loop. The refrigerant absorbs heat inside the room, then releases it outside through a condenser coil. A fan draws air across the coil, speeding up the transfer and keeping the temperature even throughout the space. This method avoids the need for separate indoor and outdoor components, making installation simpler and the system more compact.

The unit mounts on the wall of a cold room, requiring an opening cut into the panel. Once installed, the operator sets the desired temperature on the digital controller. The unit starts automatically, pulling heat from the room until the set point is reached. The fan ensures cold air spreads evenly, preventing hot spots and maintaining stable conditions. For larger rooms, multiple units can be linked, with one acting as the master to control the entire system from a single display.

Construction is a white RAL9003 casing housing the compressor, condenser coil, fan and refrigerant circuit. The refrigerant is R290, a hydrocarbon with a low environmental impact. The unit is designed for indoor use and cold rooms with panel thicknesses up to 200 mm.

Controls consist of a digital controller with a temperature display. The operator sets the target temperature between -25 °C and -10 °C, and the unit maintains it automatically. The display shows the current room temperature for monitoring.

The 0.91 kW power rating indicates the electrical load the unit places on the supply. It operates on a 220-240 V circuit, typical for professional kitchens. The 54 kg weight means the unit can be lifted by two people or a small hoist during installation. The 671 mm width, 975 mm height and 828 mm depth determine the space it occupies on the wall and the size of the opening required in the cold room panel.

Cleaning involves wiping the casing and condenser coil to remove dust and grease that can reduce efficiency. The fan and coil should be checked regularly to ensure unrestricted airflow. The refrigerant circuit is sealed and requires no maintenance, but the unit should be inspected for leaks if performance drops.

The WRA-L11-1 is a single model with no variants. It is placed in the catalogue under cold room equipment and freezing units.
