EAW-VD V Dry Cooler

• Runs 100% dry
• 304L stainless steel tubing as standard
• Aluminum fins as standard
• Ranging in capacity from 13 to 415 nominal tons
• IBC Compliant for 1.5 Importance Factor installations

Hot Process fluid enters the inlet header connection, shown in red. Heat from the fluid dissipates through the coil tubes surface and out to the fins. Ambient air is drawn in over the coil surface by the fan located at the top of the unit. Heat from the process fluid transfers to the air and discharges to the atmosphere. Cool process fluid exits the unit through the connections shown in blue.

Advanced Motor Technology

Available with Electronically Commutated (EC) or NEMA fan motor designs.

The motors on the eco-Air series are pre-wired at the factory to UL standards, reducing costs associated with field wiring. As standard, all units are wired to a common terminal box. Adding the EVAPCO controls package allows for both single point power supply and complete capacity control.

NEMA

• Premium efficient direct drive
• Zero maintenance sealed bearings
• VFD ready
• Severe Duty

EC

EC motors are the latest development in energy savings and speed control.

The high efficiency wing tip fans operate up to 3 dB less than conventional blade fans with improved part speed energy consumption.

• Zero maintenance
• Integrated speed control

Advanced Construction

Superior Stainless Steel Technology

• Constructed with high-grade Type 304L stainless steel tubing as standard
• Meets ASME B31.5 refrigerant piping code
• Available in 5/8-inch OD

Coil Design

Through the use of computational fluid dynamics (CFD) modeling software, finite element heat transfer analysis, and proprietary coil performance calculation methods, EVAPCO engineers have identified significant design elements to improve the finned coil performance. The extensive computer modeling has been refined and verified through coil performance evaluation in EVAPCO's state of the art research laboratories.

Coil Return Bend Covers

Protects the coil return bends during handling and operation

Large Inspection Panel

Easily removable for interior inspection and access to coils and fan motors

Easy Rigging

All units are designed to ship and install as a single piece

Fork Lift Channels

Standard on all units up to 27 feet in length

Individual Motor Disconnect Switches

Mounted at each fan motor to electrically isolate individual motors

Internal Step Deck

Platform and grab rail for access to elevated fan section components

Epoxy Coated Fins

• Increased corrosion resistance
• No impact on unit capacity
