Compact high-performance condensers for commercial refrigeration
The energy-efficient air-cooled condenser is perfectly tailored to Roller air coolers for use in commercial cooling. The very compact, low-noise, vertical units can be mounted at floor level or on a wall to save space. A range of proven corrosion protection options is available to cope with different environmental conditions.
The KVN is used in these areas of application
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.
Process cooling
The manufacturing industry depends on the reliable maintenance of specific temperatures to ensure high quality of the goods produced. Precise temperature control, reliability and energy efficiency are a priority.
Roller offers a wide range of heat exchangers and air coolers for process cooling.

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.
HVAC industry
Today, a multitude of different applications such as server rooms, clean rooms, medical facilities and practices, shops, offices, greenhouses, and so on, place specific demands on building technology.
The right temperature, air quality and air movement play an important role. Here, with individual heat exchangers, we offer suitable solutions for a wide range of tasks.
The robust HKN air-conditioning unit stands for barely noticeable conditioning and a comfortable indoor climate with high energy efficiency.

Cold store - KNV - Klüvers
On the heat discharge side, the available space for the condensers or dry coolers often plays a crucial role. Noise levels and corrosion must also be taken into account. Klüvers opted for a wall-mounted KVN condenser from Roller with gold lacquered fins which are resistant to the salty sea air.
