All Nortec Aqua Coolers are designed for vertical
airflow. (Horizontal airflow is available as an option).
All units are UL & CUL and MEA – listed.
All units are constructed of heavy-gauge, corrosion resistant
galvanized steel for maximum casing rigidity. Multiple fan
units are separated by full width baffles to prevent air
bypass. This provides additional casing reinforcement.
To enhance the tube life, all end panels, center supports
and partitions have collared tube holes.
The fluid coils are constructed using seamless copper
tubing on a staggered pattern. Tubes are mechanically
expanded into continuous full –collared plate-type aluminum
(or optional copper) fins for permanent metal-to-metal
contact.
Headers come equipped with vents and drains.
All coils are factory pressure and leak tested at 400 PSI.
The aluminum fans with painted steel hubs are dynamically
balanced and factory tested before shipping to ensure quiet
operation.
Fan guards are designed from heavy-gauge, close-meshed
steel wire with vinyl coating for maximum rigidity, long life
and attractive appearance.
Fan motors are heavy duty PSC or three phase open dripproof
type with permanently lubricated ball bearings and
built-in overload protection. All motors are factory wired
with leads terminating in a weather – tight enclosure
located opposite the header end of the unit.
