Established in 1970 by Giordano Riello, a pioneer in air conditioning in Italy, the company benefits from the experience of its founder in the thermal engineering industry.
Sierra is a leading European manufacturer of finned heat exchangers for civil and industrial applications.
The experience acquired in producing fundamental components for air conditioning led Sierra to expanding its product range, with remote condensers, dry-coolers and Thermofon and Thermobox convectors
Investments in research, a production philosophy focusing on maximum qualification, specialised technicians and teams, guarantee constant and high quality standards.
Sierra does not just produce: each new client is a business partner, and the optimal solution for any situation is identified, designed and manufactured in close collaboration and in accordance with the specific needs of the client.
Sierra’s core lies in its staff who, together with Giordano Riello, built this successful company.
Involving and training people is the foundation of Sierra's quality philosophy.
Enthusiasm, professionalism and teamwork are combined with continuous attention to professional retraining.
Right from the beginning, we have always been committed to creating products in line with market requirements and to reaching sales targets whilst meeting the needs of the Company and its people.
Sierra’s production philosophy involves all of the quality phases, from materials to processes, from organisational systems to the machinery used. The design phase uses state of the art software, directly integrated in the production management system, based on the principle of streamlined production.
Suitable numeric control machinery and systems guarantee high production standards and flexibility.
There can be no technological progress without continuous research.
The new CERT 3000 facility, created at the Isola della Scala plant, is another sign of the quality policy that Sierra has always adopted.
The new testing, research and experimental laboratories that Sierra makes available to developers and designers, derive from the thirty years of experience gathered in the field of research aimed at obtaining maximum efficiency for refrigerators and thermal exchangers.The laboratories use the most advanced precision technologies for measurement systems.
With CERT 3000, developers and designers of air conditioning units, refrigeration systems and thermal exchange devices benefit from a complex which is spread over 450 sq.m., featuring a testing and experimental facility with complete test services for energetic efficiency that only a leading company like Sierra can provide.
The CERT 3000 laboratory can carry out tests on small and medium thermal exchange devices, with non-standard voltages and network frequencies (60Hz, 150-400V). The laboratory employs high precision thermistors, flow, humidity and pressure transducers that are periodically calibrated to acquire data that certify and guarantee the test results. All the refrigerating machines use eco-compatible refrigerant fluids. In addition, a prototype workshop has been created in the laboratory area. In addition, a prototype workshop has been created in the laboratory area. Sound pressure measurements can be carried out in accordance with UNI EN 3744:1997.
