Cleaning of heat exchangers and cold stores – new cleaning options in Switzerland

The cleaning of finned heat exchangers in the interior of food production or storage is always a critical issue and is therefore sometimes postponed as long as possible. Even in these areas, JetMaster offers the possibility of cleaning heavily loaded finned heat exchangers without removal. Here special nozzles are used.
The extremely small amount of water required for cleaning – less than 0.50 liters per minute – can be collected together with the residues for disposal.

At the beginning of this year (2018), Puraclean further strengthened the cooperation with mycon and Kipp Umwelttechnik and additionally started the cleaning of different types of plate heat exchangers and shell-and-tube heat exchangers. The facilities required for this purpose and mycon’s many years of international experience are now available in full to Puraclean. Even exchangers of this type are either mechanically cleaned by blasting or with mostly "green" chemicals, which is already used in the food industry.

Approved by Wessling GmbH (Hannover) certified process for cleaning cold stores

Puraclean also carries out cold storage cleaning. For this purpose, a method developed by mycon and a cleaning agent also developed by mycon will be used. Procedures and cleaners have been officially tested and certified by the company Wessling, including the operating instructions of mycon for food compatibility and safety. When commissioning the Puraclean, this ensures that the cleaning process is perfectly compliant with food law. The method has clear advantages over other methods:

– Cleaning without shutting down the cold store
– goods can remain in the cold store during cleaning (only about 40% free space is needed)
– Savings on rental costs for a refrigerated container
– No additional personnel costs for the relocation of goods
– No interruption of the cold chain
– Frozen temperature is maintained, it thus accounts for the additional cooling down necessary additional energy costs
– Less time (about 5 hours for 45 m²)
