The Trane Series R helical rotary screw chillers RTWD and RTHD have transitioned to low-GWP refrigerants R-513A and R-515B. The RTWD model, which has a capacity range of 80 to 250 tons, utilizes R-513A for comfort cooling and low-temperature needs, and R-515B for heating. It can achieve temperatures of up to 165 degrees F, making it an ideal solution for boiler replacement. RTHD, with a capacity range of 175 to 400 tons, uses R-513A for all requirements.
Both chillers are now available with Trane’s Symbio 800 equipment controller, which integrates with building automation systems (BAS) for better energy management and operational insights.
