In the early 1970’s P. RECATALA was formed, it manufactured steam boilers. During the 1978’s they created and design their own steam boilers and in the year 1987 VALTEC-UMISA, SA was formed.

In 1997 the company received the Quality Systems Certificated according to ISO 9000:94 applying the design, manufacture and installation of our equipment.

Currently we hold the certificate for security according to ISO 9001:00. This has allowed us to obtain our quality certificate in line with the requirements in the Annex III module H of the Pressure Equipment Directive 97/23/CE, requiring members of the EEC to follow the European legislation referring to pressurized equipment since May 2002.

We deliver our equipments with the label “CE” and Declaration of Conformity, and with the technical dossier revised by a Notify Body which assures and certifies that the pressure equipment meets to the rules. Our range of boilers includes firetube boilers from 5 T/h to 40 T/h. burning fuel oil or gas as fuels, being the first Company in the Spanish market in the sale of the steam boilers from 15 tn/h.
