Air coolers / Evaporators
Special air coolers with humidification and dehumidification function
SV
HFC | CO2 | Water | Brine
Cooling, heating, humidification and dehumidification in one unit
EC fans for energy-efficient operation (up to top mark A)
Heat exchanger with full corrosion protection for use in aggressive environments
Ideal for rooms in which a minimum humidity level must be maintained
Special top-class air cooler
This highly efficient special air cooler can be used for a variety of applications where limited humidification and dehumidification are required. Common applications include sausage ageing rooms, plant cooling, wine cellars, butcher shops and others. The entire heat exchanger features high-quality corrosion protection as standard with powder-coated, tin-coated tubes and a fully coated heat exchanger coil.
The SV 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.
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.
keit an die Kältetechnik, wenn es um Ausfallsicherheit, Hygiene oder Energieeffizienz geht. Roller ist der Spezialist für Luftkühler, Verdampfer und Wärmetauscher für den gewerblichen Bereich.
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.

Ripening room - SV - Butchery
When renovating and expanding its butcher shop premises in Büchenbach/Germany by adding an ageing and low-temperature storage room, the company Lorz chose a special evaporator from Roller which offers cooling, heating, humidification and dehumidification in a single unit. An external control unit which keeps the humidity and temperature in the room constant ensures the best possible ageing results.

Plant cooling - SV - Sachsenforst
The state-owned company Sachsenforst has its own cold room where it stores the saplings it grows itself. They are kept fresh until they are planted for reforestation of the Saxony State Forest with indigenous tree species. The company Kälte Service Geßner relies on Roller's SV evaporators which can easily cope with the high air humidity.

Test chamber - SV - Cooltherm
In a variety of applications, Cooltherm uses our special air coolers of the SV type, where not only cooling but also, to a limited extent, humidification and dehumidification are required. The set of these pictures shows the SV air cooler integrated into chilled water systems, 1/ in a test chamber, in which a temperature between 20 and 40°C, with a relative humidity between 50 and 75%, must be maintained according to the test specimens. 2/ in a calibration room with room temperatures between 18 and 35 °C, at a relative humidity of between 40 and 75%.
