Oil as a lubricant in a chiller makes for a significantly more complicated machine. Smardt oil-free centrifugal compressor technology boosts energy efficiency, cuts operating costs and is now well-proven worldwide.
Konvekta high performance energy recovery coils are specially designed to achieve very high recovery efficiencies. Their unique design has headers on both sides that create cross-counterflow that is almost perfect counter-current.
Using ASHRAE 62, engineers can take advantage of the IAQ Procedure which allows outside air to be set at any level, producing a steady state contaminant level equal to or less than those achieved by using the Ventilation Rate Procedure (VRP).
