Compressed air as a type of safe technological energy carrier is widely used in many industries. In economically developed countries costs for the production and distribution compressed reach 10 % total costs. The analysis systems industrial sector shows that efficiency at relatively low level. This due to fact insufficient attention paid these since monitoring has certain difficulties – presen...

T a new major technological advance is available that can help control-valve users avoid many of the problems and inefficiencies associated with using compressed air as a power medium. The new solution uses electric power and eliminates dependence on compressed air. This totally electric solution is appropriate and cost-effective for a wide variety of control-valve applications, including those...

In OPCAB (off-pump coronary artery bypass) operations, development of cardiac arrest during the distal anastomosis to obtuse marginal coronary artery leads to significantly low blood pressure in the ascending aorta. Therefore, blowing of compressed air in high flow on not-slinged coronary artery may cause air mobilization from the coronary artery system into the ascending aorta that may result ...
