The EWAD-MZ chiller series achieves the highest overall efficiency and offers real world benefits such as lowest energy costs and carbon footprint, making it the first choice for designers, consultants and end users over traditional air cooled chillers for their buildings. The heart of the EWAD-MZ chiller is Daikin's proven screw compressors incorporated with industry-first variable volume ratio (VVR) technology that allows the internal compression ratio to optimize the chiller's performance at all ambient conditions. Marco Flavio Calanca, marketing manager at Daikin Applied Europe, said: "Thanks to this innovative solution, Daikin VVR can avoid those energy losses typical of traditional compressors designed with fixed volume ratio. No more over-compression phenomena are experienced with Daikin VVR."
