EWAD-TZSSB/SLB

Air cooled screw inverter chiller,

standard efficiency,
standard/low sound

› Optimized energy efficiency both at full and part load conditions
› Inverter stepless single-screw compressor
› Advanced compressor technology featuring integrated inverter
and variable volume ratio (VVR)
› Compact design for small footprint and minimized installation
space
› Low operating sound levels are achieved by the latest compressor
and fan design
› One or two truly independent refrigerant circuits for outstanding
reliability
