The FAV/FAVT is used in these areas of application
Food Industry
Especially high demands are placed on refrigeration in the food industry. Hygiene, energy efficiency and reliability are the top priorities.
But even when it comes to requirements for refrigerants, corrosion protection, material combinations, practical fin spacing, optimised tube and fin geometries, uniform air distribution or energy efficiency, Roller offers the optimised solution for every performance range and every application with its wide product range of evaporators and air coolers.
Storage & Logistics
The requirements for cooling in warehouse logistics could not be more diverse. The tasks are very specific:
In plus cold stores for fruit and vegetables, it is crucial that the sensitive chilled goods are stored in the right conditions and cooled gently. Dairy products are highly perishable and require a closed cold chain. Ripening chambers turn fruit varieties into products ready for sale.
In deep-freeze warehouses, uniform temperature distribution is important, reliable air coolers protect against thawing of the goods. In order-picking rooms, the impact on employees must be minimised. Roller offers a variety of individual solutions for all applications.
Commercial refrigeration
The range of refrigeration technology for the retail trade is broad. Whether it's a butcher's shop, bakery, flower shop, petrol station, restaurant or supermarket - each sector has its own requirements to ensure optimum product quality.
One thing is always in the foreground: reliability in refrigeration technology when it comes to failure safety, hygiene or energy efficiency. Roller is the specialist for air coolers, evaporators and heat exchangers for the commercial sector.

Potato warehouse - FAV - Berchtold
Potatoes that are stored for a longer period of time start to sprout. This process can be delayed by chemical treatment (powdering) or cooling. Since powdering has been banned in Switzerland, the direct marketer decided to cool his stored potatoes. Berchthold Kältetechnik installed a refrigeration system with two Roller FHV/FAV evaporators paired with a Silensis outdoor unit in the approx. 50 sqm hall.

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.
