Our brand
Our brand S&P has achieved worldwide recognition, thanks to our staff, quality and reliability, and innovation. The philosophical principles on which S&P was founded, and which are maintained to this day, are:
Proprietary technology:
For the S&P project to be strong and consolidated over time, it was necessary that it be based on creativity and providing distinctive products, avoiding imitation of the competition. Over the company’s history, S&P has registered 182 patents, more than 59 industrial models and 4 utility models.
Internationalisation and Growth:
It was clear that in order to ensure the company’s future we had to open up to the world and to enter new, highly competitive markets. This has led us to carry out on-going improvements to our products. S&P is currently a world leader in ventilation, with production centres in Europe, America and Asia. A powerful distribution structure, through subsidiaries and exclusive distributors, allows S&P to be present in all world markets with both products and service.
Self-financing:
One of the strengths of S&P has been our constant growth and policy of reinvesting profits in on-going technological improvements, both in research and production and in marketing. This has allowed S&P to be a self-financed company with complete independence in our decision-making process.
