  • Reducing heating / cooling pump consumption by over 50%
    Frese
    The pumps installed in all newer heating and cooling systems are almost always frequency-controlled pumps, which are self-adjusting and regulate according to load. To exploit the pump optimally, it must be set and controlled...
  • Plate heat exchangers for commercial applications
    Stokvis Energy Systems
    A hot water system using a plate heat exchanger (PHE) heats water instantaneously and only when required, making it intrinsically energy-efficient. Calorifiers and direct-fired water heaters are less reliable and can empty...
  • Technological advances in boiler manufacturing
    Stokvis Energy Systems
    Technological advances have increased the efficiency of commercial boilers to the extent that established, well-proven technology ensures high efficiency and reliable performance. However, that does not mean the industry is...
