High-performance air coolers for industrial refrigeration applications

 

The FHVI high-performance air cooler is particularly suitable for cooling and deep-freezing requirements for industrial refrigeration applications where hygiene and corrosion protection play an especially important role.

Due to its highly efficient, aligned tube system with large fin spacing of up to 12 mm, it guarantees low dehumidification and is ideal for use in food processing.

Certificate

Eurovent

In many sectors, such as the food industry, the energy sector, logistics, mechanical engineering or building services, cooling is always system-relevant and decisive for the quality of processes and thus of products. As a manufacturer of high-quality components for refrigeration and air-conditioning technology, we know:

The credibility of the performance data of the machines used is a decisive aspect in ensuring your quality requirements.

That is why we have the performance data of our products certified by independent laboratories as part of the Eurovent programme. Eurovent is an independent organisation that ensures that the equipment of the participating companies is tested under the same conditions and is therefore more comparable.

As with most food manufacturers, the various processing procedures require different refrigeration technology in order to keep the cold chain in the building unbroken. This food company in Belgium which manufactures salads and sauces uses Roller air coolers in its processing, packaging and storage rooms. In rooms where people work, textile hoses were used to ensure uniform, draught-free cooling.

BorWin3 is the third offshore grid connection project off the coast of Borkum which brings ashore the wind power produced out at sea by two wind parks. For the offshore converter station manufactured in Dubai, Roller equipped the technical rooms with specially produced HVS/HVIS and FHV/FHVI air coolers. It also fitted HKN air conditioning units in the crew's communal areas.
