Personalized Products

Vrcooler offers tailor-made products thanks to the possibility to personalize them and to collaborate with the customer in designing them.
The exchanger section shown here shows all the elements on which it is possible to make a personalization.
One of the fundamental components for the exchangers is the geometry that is used to maximize the thermal flux between the two fluids.
Special procedures are available, from treatment of surfaces to TIG welding, that Calligaris provides to further customize the product.
Thanks to its accurate three-dimensional design and to modern punchers and numerical control bending machines.
We make tubes of different diameters, with a greater number of thicknesses and different materials such as copper.
We have heat exchanger design software which Guentner and Cabero are using,  Vrcooler offers tailor-made heating and cooling unit.

OD 15,87 mm : With wall thicknesses of 0,40mm plain as standard ; 0,50 - 0,70 - 1,0mm plain upon request.

Tubes have the suitable quality for refrigeration and air conditioning.


The available tube arrangements and fin properties used in our company are given in details in the following pages. In addition to 8006 H22 aluminum alloy, copper foils, stainless steel fins and hydrophobic, hydrophilic, goldepoxy coated foils are also used upon request.


Galvanized, stainless steel, steel, copper and aluminium sheets are used as casework materials. Other appropriate materials can be used upon request.


The most appropriate brazing material is chosen according to the application area.


Unless otherwise stated, steel manifolds are used for dry coolers, water and steam coils. For all other products, copper manifolds are used.

Fin Materials

Different type of coatings are applied depending on application areas and corrosion conditions.

Coils can be manufactured from copper, hydrophilic, hydrophobic or gold epoxy coated fins.

Depending on customer request, tin coating can also be applied to coils.

Fin Surfaces

Fin surfaces can be manufactured as ‘flat’, ‘corrugated’, ‘louvred’ types depending on customer requests. Please find some samples of these surfaces below.
