KV-CEI isolates electronic systems from air pollutants, dust, chemicals and evaporation of water vapor. It is an enclosure that works by closing the cooling circuit system of the outside atmosphere (where evaporation escapes) with a breathing chamber. The outside air inflates and deflates the bladder when the fluid levels inside the isolation tank expand and contract from the temperature changes of the system liquid.
A low-pressure relief valve helps prevent overpressurization of the system in case unforeseen air is trapped inside the fluid lines. An open shut-off valve that draws air allows the system to drain and fill with adequate fluid levels during a normal preventive maintenance cycle. By isolating the internal volume of the tank from the existing external atmosphere, the system prevents the evaporation of water and the entry of contaminants into the air in the water-glycol solution.
A check valve provides overpressure protection and a visual level indicator allows local confirmation of the coolant level. In addition, a port allows you to add an optional floating standard liquid level switch for remote low-level refrigerant indication. "The design of KV-CEI is versatile enough to allow the addition of low-level liquid sensors when necessary in a turbine," Mosher says that custom designs are also possible. "We can also design many mounting options to fit a particular mounting pattern." The objective is to keep wind turbines generating energy even in extreme temperatures, without adding more maintenance visits to a site. "The return on investment for the KV-CEI solution can be measured in just a few weeks in warmer climates and at high operating temperatures," says Mosher.
