In 1995 Intersam was founded by professionals in the sector for the manufacture of heat exchangers. In a few months, the manufacture of batteries in different formats is expanded, and new battery production lines are created. 100% of the billing was national and the number of clients was very small.

Nowadays, in addition to heat exchangers, we are capable of manufacturing any type of unit to satisfy any need in the field. of refrigeration and air conditioning and for this reason it can be said that Intersam has already established itself as a leading company in its sector. For this reason, we maintain a very active participation in everything related to fairs, both nationally and internationally, dedicated to the refrigeration or air conditioning sector.

We want to share with our clients and with everyone who visits our website the most outstanding events or news related to our work environment. In addition, this section is intended to be a showcase of our activity, with our most outstanding facilities, projects, etc.

For that, this section of “News” is created. From here, we want to keep all our visitors informed of everything that surrounds us and that, in our opinion, they should not be lost because it is considered of common interest.

In addition, from this section, our clients who use the Intersam Unit Selector software are informed on all updates and thus work at all times with the latest version available, thereby ensuring better use of your equipment.
