Horizontal Isotherms

The BUPOLSA isothermal tanks are manufactured by means of a sandwich structure composed of polyester reinforced with fiberglass (PRFV), closed cell polyurethane foam and finally another layer of PRFV.

BUPOLSA has its own machine for spraying polyurethane foam, so the manufacture is faster than other manufacturers.

The polyurethane foam used by BUPOLSA is of high density and closed cell so it provides a high quality insulation. In this way we isolate the product stored inside 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 contain at a few specific degrees centigrade without suffering the contrast of temperature of the outside of the tank.

(Installation instructions).


The storage volume range of these tanks is very wide depending on the tank model. For more capacities, please contact our technical-commercial department.


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