Our Environmental Commitment

  • Sustainable Resource Management

    Maximum efficiency, reduced emissions: Our manufacturing plants comply with the ErP (Ecodesign Directive 2009/125/EC), which requires the gradual reduction of energy consumption of heat exchangers and, in general, of energy-using equipment and engines manufactured in the EU. Additionally, by using natural gases such as ammonia and propane, the company delivers high efficiency products while ensuring a low environmental impact.

    Our Environmental management System is certified to  UNI EN ISO 140001 : 2015 standard
