What is the EVAPCO eco-Air APEX Dry Cooler?
The eco-Air APEX is a factory-assembled dry fluid cooler developed for high-capacity data-center and industrial heat rejection. EVAPCO publishes a CTI-certified nominal range of 9,060–11,490 MBH and states that the largest listed condition equals 3.37 MW at 115°F inlet, 105°F outlet, and 95°F entering dry bulb. Those temperatures are essential context; a different approach to ambient, glycol mix, or flow changes capacity and fan demand. A project selection should state total fan power, fluid pressure drop, sound, recirculation clearances, controls and communications, fan-failure derating, freeze strategy, coil materials and cleanability, shipping and lifting limits, and performance at the site's actual summer design point. The nominal condition includes only a 10°F fluid drop and a 10°F approach to outdoor air, so it must not be applied to a colder loop without reselection. CTI certification supports comparison at the certified point but does not establish the surrounding roof's airflow or annual energy use. Buyers should request performance at every required ambient and load condition, including night sound limits, minimum fan speed, one-fan and one-control-section outages, fouled coils, and design glycol. Structural reactions, service zones, crane access, discharge recirculation, and the controls response to sensor or network failure also need explicit review.
