Founded in 1970 by Giordano Riello, a pioneer of air conditioning in Italy, the company benefits from the experience of its founder in the thermal engineering sector.
Sierra is a European leader in the production of finned block heat exchangers for use in civil and industrial applications.
The Sierra heat exchanger catalogue offers a wide range of solutions in terms of external copper tube diameters (or copper-nichel tubes), coil patterns and fin types (alluminium or copper) available.
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.
Any customer expects that the product will satisfy his/her needs for the entire product lyfecycle.
At Sierra, teamwork, engagement, and sense of responsibility are key factors for achieving our quality objectives.
Our Quality Policy summarises our commitment for excellence and includes:
Sierra pursues market leadership by being a customer-focused, a globally acting company delivering exceptional quality, innovation and value. The key to our success lies in our ability to satisfy our customers with excellent quality of goods and services, striving for zero defects and no waste.
Sierra designs and manufactures heat transfer products for a wide variety of applications and markets, delivering the solutions the customers need.
For such purpose Sierra works with installations, facilities, and working methods that guarantee safety at work and environmental protection.
The Company’s ambition is the satisfaction of the most demanding needs of its customers, stimulating the growth of the professional knowledge.
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 test small and medium-sized thermal exchange devices.
The laboratory employs high precision thermometers, flow, humidity and pressure transducers; a periodical calibration of instruments is performed by an ACCREDIA accredited laboratory.
The research is carried out for the optimization of heat exchangers and air conditioning machines with new low GWP refrigerant gases, in order to allow out customers to comply with the rules of the F-Gas regulations, for the reduction of the amount of refrigerant gas, and Ecodesign legislation, for the reduction of electrical absorptions.
In addition, in the laboratory area, a workshop has been created for the realization of prototypes.
