Bakery cooling - FAV - Biaggini
For the daily fresh baked goods in the bakery displays, sophisticated refrigeration technology is required in particular to meet the requirements of the variety of different baked goods. Fast freezing times, small temperature differences, air distribution and humidity control during storage add complexity to the task. For careful conditioning of sensitive bakery goods, the focus of evaporators is on the largest possible heat exchanger surface area with low dehumidification. For the conversion of one of the largest bakeries in Switzerland, Biaggini installed a CO2 refrigeration system with 250 kW cooling capacity, including heat recovery, air conditioning, and humidity control in the cold rooms. Biaggini relies on the reliable technology of Roller FHV/FAV air coolers when it comes to cooling the refrigeration and deep-freeze chambers.

Butchery cooling - DAN - Biaggini
High-quality meat and sausage products have a long tradition in the canton of Ticino (Switzerland), and preparation is still done with great passion. That's why these specialities are a real treat for the palate. In addition to the good ingredients and the know-how, the appropriate equipment is of course also required for the perfect result. The butcher's shop Bozzini in Biasca has invested in advanced refrigeration and counter technology and commissioned Biaggini to equip the refrigeration systems. The technology behind the attractive salesroom is all made by brand-name manufacturers. The DHN/DAN ceiling-mounted air cooler was chosen for hygienic and draught-free operation in the cutting room. In the two cold rooms, Biaggini relies on the tried-and-tested FHV cubic Roller air coolers, which not only ensure the correct temperature control but also the high quality of the chilled goods.

Reconstruction large kitchen - DLKA - Schlittenhardt
Schlittenhardt's task was to upgrade all of its customer's cooling equipment while its large kitchen was still operating. When modernizing the five cold stores, Schlittenhardt opted for various products including DLK/DLKA evaporator units from Roller. To ensure reliable operation, the units which were previously used inside were installed on the canopy and the very latest control systems were used.
