EWAH-TZXSB/XLB

Air cooled screw inverter chiller,

high efficiency,
standard/low sound

› High energy efficiency both at full and part load conditions
› Inverter stepless single-screw compressor with DC electrical
motor
› Advanced compressor technology featuring integrated inverter
and variable volume ratio (VVR)
› HFO R-1234ze(E) Refrigerant with Ozone Depletion Potential equal
to zero and extremely low Global Warming Potential
› 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
› Continuous fans speed modulation thanks to inverter driven fans
to improve part load efficiency
