The CEO of WIKA in Germany has stated that by 2030 , 80 % of its measurements will be digital .
pipes in HVAC systems can reduce the diameter of condenser and evaporator pipes and coils , meaning less material , a potentially lower carbon footprint and more efficiency . The smaller internal space of an efficient copper pipe also requires less refrigerant .
By nature , copper is not a highly reactive metal , something
extremely beneficial for pipework that needs to carry refrigerant over long periods without eroding or damaging the HVAC system . Having a natural protection against corrosion is a great advantage and part of what makes copper a long-lasting standard for HVAC system systems . Most HVAC systems are placed in tightly-built spaces , creating moist environments that encourage the growth of mold and mildew . Copper has antimicrobial properties that discourage their presence from building up in hard to access areas .
PRESSURE INDEPENDENT CONTROL VALVES Automated Control Solutions ( ACS ) supplies several brands of valves having begun life as a distributor of Honeywell before the latter terminated its distributor model and went direct to market . Today , ACS primarily distributes Danfoss valves , and particularly chilled water and air handling unit ( AHU ) valves . It services HVAC system integrators and mechanical contractors with high end quality international products .
Adrian Hofmann , Technical Sales and Support at ACS , says : “ When it comes to the big tenders for large buildings and shopping malls , engineers like good quality valves and a Danfoss valve will last almost forever . There are two different sets of valves we do from Danfoss : conventional two- and three-way control valves with manual balancing . This is the traditional way that
