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%.
