The new Y- and R2-Series
outdoor units from Mitsubishi Electric
are designed to be more flexible, smaller, and easier to maintain than previous HVAC units. Both are shorter and narrower than previous models to facilitate installation, are enclosed in metal panels to minimize noise pollution, and feature piping connections and a control box located at eye level to make maintenance easier. The modules come in sizes from 6 to 10 tons, can be combined to form a system up to 30 tons, and use the company's Variable Refrigerant Zoning System to control as many as 50 separate zones.
