Mark Eire strives for unparalleled quality. The production of our climate control systems takes place in our own factories and only takes place in accordance with the best certification methods and quality marks. This allows us to guarantee a constant quality. Together with the years of accumulated knowledge and experience, this gives you the security you desire.

The entire range of Mark AERFLOW heat recovery units are certified according to the EUROVENT quality mark. This European energy label for air handling units classifies an AHU type on various points based on the European standards NEN-EN 1886 (mechanical properties) and NEN-EN 13053 (nominal values and performance).
To ensure that all suppliers use the same testing method, and above all maintain their quality, EUROVENT carries out a check. In addition, companies are regularly checked whether they still meet the measured report figures. In this way, the customer is always guaranteed of a high-quality product.

Mark Eire has been ISO 9001 certified for 25 years. EN-ISO 9001:2015 is an international standard that sets requirements for an organisation’s quality management system. The system emphasizes the importance of continuous development and improvement in relation to customer requirements, product and service quality, processes and performance. The quality management system is examined annually by an auditor from NSAI.
By regularly looking critically at our quality system and our processes, the quality we deliver remains of high level. We are therefore very pleased to have again obtained the ISO 9001 certificate.
