Vertical isotherms, elongated ferrule or legs

BUPOLSA isothermal tanks are manufactured by a sandwich structure composed of polyester reinforced with glass fiber (GRP), closed cell polyurethane foam and finally another layer of GRP.

BUPOLSA has its own polyurethane foam projection machine, which makes it faster to manufacture than other manufacturers.

The polyurethane foam used by BUPOLSA is high density and closed cell so it provides high quality insulation. In this way, we isolate the product stored in its interior from the external meteorological conditions, being able to have temperature contrasts of more than 90ºC.

This type of tanks is used for all types of substances that require the maintenance of the temperature of the product to be contained at a certain degree centigrade without suffering the temperature contrast of the outside of the tank (installation instructions).


The range of storage volume of these deposits is very wide depending on the model of the deposit. To consult more capacities, contact our technical-commercial department.


Applications: These deposits are indicated for those cases in which, for specific specifications, it is necessary to maintain the product to be stored at a certain temperature.

  • Water
  • Soda
  • Wine industry (lung deposits)
  • Pasteurizers
  • Digesters
