LAE ELECTRONIC is a leading European producer of electronic controllers. Its trademark is renowned for quality, innovation and reliability in over 60 countries to which it exports.

This is confirmed by the company’s well-established partnerships with leading OEMs in the refrigeration, heating and air-conditioning industries.

Millions of commercial refrigerators, refrigerated cells, furnaces, incubators, air-conditioners, greenhouses, climatic chambers and many other appliances work perfectly because of the company’s longstanding experience in this field, its in-depth know-how and its ongoing commitment to find increasingly sophisticated technical solutions.

For LAE ELECTRONIC, researching and manufacturing control functions to provide energy saving for different systems have not been governed by recent market trends but are deeply rooted in our company philosophy, which strongly focuses on research to protect the earth’s resources.

In recent years, LAE has developed unique self-learning algorithms, with proven reliability and efficiency, for optimizing management according to the operating conditions of the refrigeration system, providing extremely high energy saving.

Always perfectly in line with its ethic code, LAE ELECTRONIC has not been easily enticed by delocalization. Instead, the company has decided to continue production at its original production unit, in Western Europe, protecting the jobs of those who have contributed over the years to its success as a company. This has also been achieved with drastic re-organization and cultural renewal, providing a reduction in costs without forgoing the company’s high standards of efficiency and quality.

LAE ELECTRONIC believes in synergies, via the ongoing fruitful exchange of experiences and ideas with its customers, which is essential for obtaining excellent results.
