Industrial air conditioners for hazardous environments
With two special Protherm products CVE0800220Z003 and CVE2000261Z000, Cosmotec offers an air conditioning solution with increased corrosion resistance. The two air conditioning units are therefore suitable for operation in very critical working conditions and have a longer average life than standard air conditioning units. This is possible thanks to dedicated solutions to protect elements of the carpentry, the cooling circuit and the electronic control, components that are more subject to possible corrosive attack in certain environments with chemically aggressive substances.
The printed circuit of the electronic board, however, located on the evaporator/cabinet side, and the display, installed on the panel, are covered with a protective resin layer that prevents substances or moisture from depositing on the conductive copper tracks.
The panel, part of the housing, which is mainly exposed to the external environment, is made of stainless steel, which has resistance properties against corrosion/oxidation phenomena.
The exchangers (condenser and evaporator), the largest elements of the refrigeration circuit, are protected by a specific treatment depending on the type of component. In addition, the external part of the refrigeration circuit, both pipes and welds, are also coated with a treatment to increase protection against the action of corrosive agents.
The above mentioned air conditioners are also available in a version with a painted sheet metal panel (codes: CVE0800220Z004, CVE2000261Z001) in case only the protection of parts with copper is required.
A viable alternative, if water is available and can be used as the cooling medium, are EXW water/air exchangers, as they have no parts of the unit exposed to the outside environment. The air/water exchangers are optionally available in a version with stainless steel casing.
