• Evaporator Coil
The design of the V shaped evaporator coil provides maximum surface area for heat transfer which
provides a high sensible heat ratio (SHR) of > 0.9. The coil is constructed from copper tubes with aluminum
fins. Low air pressure difference across the coil reduces fan energy even at higher air flow rates, and the
coil section is light and compact.
• Condensate Drain Tray
With a metal condensate drain tray placed under the coil assembly, condensation drains to a
condensate outlet connection.
• Variable Speed Evaporator EC Fan
The cooling module is equipped with a high-efficiency EC fan made of aluminum
that delivers high airflow rates to meet the airflow demands during the entire
time of operational. The EC fan has a smooth speed variation across its operating
speeds that work in synchronization with the entire system components to deliver
precise output capacity.
• Electronic Expansion Valve
The system is incorporated with an electronic expansion valve that monitors
temperature and pressure signals simultaneously to maintain precise adjustment
of the refrigerant flow. The electronic expansion valve ensures even flow
distribution from each end.
