Page 4: Introduction
Introduction The ARIA EC compact air conditioning module is available in two sizes for conditioning rooms from 12 to 50 m². ARIA EC has been designed to match with very last rules in energy savings and comfort. It is equipped with new generation electronic commutation (EC) motors whose electric consumption is lower than motors used in traditional fan coils. -
Page 5: Main Components
Main components Fan motor The ARIA EC unit is equipped with a centrifugal forward curved single scroll fan with double inlet. The fan (s) will respectively produce a nominal airflow at 40 Pa static pressure from 400 m /h (size 10) to 900 m /h (size 40). -
Page 6: Filter And Access
Electric heater The electric heater is of the bare wire resistive type installed in the fan discharge air stream, assuring optimum coverage and maximum heat exchange. Available as standard with a capacity of 500, 800, 1200, 1500 or 3000 Watts, the 230 V/1/50 Hz power supply is provided directly from the controller or via a relay and a fuse. -
