EWAT-B-SS/SL

Air cooled scroll chiller,

standard efficiency,
standard/low sound

› First R-32 air cooled chiller with Scroll compressors in the market › Fan speed modulation to ensure precise airflow control and
› Choosing for an R-32 product, reduces the environmental impact optimized condensing temperature
with 68% compared to R-410A and leads directly to lower energy › Possible to set up detailed time bands to reduce fan rotation
consumption thanks to its high energy efficiency speed and therefore sound emission
› One or two truly independent refrigerant circuits for outstanding › Thanks to the Dynamic Condensing Pressure Management, the
reliability chiller controller adjusts the condensing pressure set-point to
› MicroTech III controller with superior control logic and easy minimize the overall chiller power input
interface
› Low operating cost and extended operating life thanks to the
careful design aimed to optimize the energy efficiency of the
chillers and to improve installation profitability, effectiveness and
economical management
