REC-RBCT commercial cubic evaporators

High efficiency and uniform cooling for commercial cold rooms.

The versatile solution for cold rooms from 20 to 600 m³

Managers of retail outlets, production departments or small storage areas require compact cold rooms that can guarantee power and microclimate stability to handle constant variations in product loads and frequent door openings.

When airflow is insufficient or cooling is not distributed evenly, air stratification occurs. This leads to uneven temperatures inside the cold room and inconsistent product cooling, which compromises product quality, reduces shelf life and increases energy consumption.

To solve these critical issues, Refteco has developed REC-RBCT cubic air evaporators, a robust and versatile range that ensures efficiency, uniform cooling and high performance in all operating conditions.

Advantages of REC-RBCT cubic unit evaporators

Consistently high performance, with cooling capacity from 1.5 up to 63 kW (SC2) provided by internally ribbed Ø12 mm copper tube heat exchanger and optimized geometry, ideal for cold rooms from 20 to 600 m³.
Uniform cold distribution thanks to the high airflow rates and optimised fans, which minimize temperature fluctuations and maintain a stable storage environment.
Reduced defrosting frequency and lower consumption, due to the optimized exchanger volume, fin spacing (4/6/7/8/10 mm) and high-efficiency axial fans (Ø250–500 mm, AC/EC motors, ErP compliant, IP54 rated).
Maximum system flexibility, with versions for HFC/HFO (REC) and CO₂ (RBCT). Over 144 models allow for precise configuration for any cold room type or layout.
Superior durability and simplified maintenance, thanks to the RAL 9002 powder-coated galvanized steel casing, the AISI 304 stainless steel screws and a drip tray with rounded, welded corners that speeds up maintenance and reduces downtime.
Reliability in harsh environments, with options such as ATEX fans, insulated trays and protective coil treatments to ensure continuous operation even in demanding conditions.
