FLEXPRESS
The revolution in the management of hydraulic pressure
Centra International Technologies proudly introduces FLEXPRESS™, a groundbreaking innovation in closed-loop hydraulic pressure damping. This patented solid-state technology ushers in a new era for all closed-loop hot water systems (solar water heaters, heating systems, etc.) by delivering unparalleled performance, reliability and safety.
FLEXPRESS Project
FLEXPRESS™ is the result of thorough research aimed at addressing the problems arising from the malfunction of closed water circuits. Inadequate maintenance of expansion vessels often leads to reduced efficiency of these systems, resulting in increased energy costs. FLEXPRESS™ comes to provide a definitive solution to this problem, ensuring the smooth and efficient operation of closed water circuits, providing economy, safety and contributing to a greener future through reduced energy consumption and a more sustainable design.
Certified innovation
The FLEXPRESS™ technology has been rigorously validated and patented by the Hellenic Industrial Property Organization (ΟΒΙ). This patent, accompanied by a detailed Evaluation Report, recognizes FLEXPRESS™ as an innovative, inventive and industrially applicable solution, superior to any existing method. It demonstrates beyond a doubt that the current technologies used in solar thermal systems are ripe for advancement through innovative approaches such as FLEXPRESS™.
This globally patented technology from Centra International Technologies eliminates the need for regular maintenance of existing old-style expansion tanks, which are prone to failure and require constant and regular maintenance. Experts liken the innovation brought by FLEXPRESS™ to LED lights replacing incandescent bulbs.
FLEXPRESS™ is the modern technological solution that ensures optimal pressure management in closed-loop systems, resulting in:
• Increased energy efficiency: Optimized pressure regulation translates into reduced energy waste and lower operating costs.
