Reflex continues to stand for, now in its fourth generation of family ownership, the strengths that helped to make us a great company: first class German engineering, enduring understanding of the underlying technology and consistent alignment with client requirements when it comes to heating and installation engineering.

With SINUS, Reflex has a strong brand for distribution technology and hydraulic points in its portfolio. For more than 40 years now, the brand has stood for energy-efficient products in heating and air conditioning technology. The special feature of SINUS is the individual adaptation of the products to the respective customer requirements.
