BOREAS Dry Cooling Systems

BOREAS® dry cooling systems are designed for facilities operating with lower dry bulb temperatures and/or higher outbound process fluid temperatures. BOREAS systems deliver safe, dependable, rugged and efficient process cooling.

How It Works

BOREAS dry coolers circulate process fluid through bundles of copper tubing and large fans pull outside air across the fins to cool that process water. These dry cooling systems also maximize energy efficiency with Smart Programming that cycles fans on and off in stages as cooling demands change.

NIMBUS provides BOREAS dry cooling systems in a variety of configurations to accommodate the spatial and cooling requirements of nearly any facility.

Why It's better

BOREAS systems deliver years of efficient cooling while minimizing the risk of Legionnaires’ disease, conserving water and eliminating the costly maintenance programs associated with traditional evaporative coolers.

All BOREAS systems can be upgraded to VIRGA™ adiabatic systems if needs or local legal requirements change.

Features & Benefits

Fans with Smart Programming cycle on and off in stages (AC) or ramp up and down in speed (EC/AC with VFD) as needed to maintain optimal energy consumption
EC or AC Fan Motors (with or without VFD) minimize energy consumption (BOREAS H-Series only available with EC)
Stainless Steel Frame ensures years of operation compared to traditional dry coolers
Easy Access Lift Points are bolted to the internal structure of every fan section for quick, simple and safe lifting and positioning
UL/UL-C Industrial Control Panels custom-built by NIMBUS offer direct 460V, 208V or 575V applications as standard with fully contained PLC or digital controls
Wide Range of Heat Rejection from 5 tons to 540 tons per unit
Minimal Footprint requires less space than traditional dry coolers

Ready Day One

BOREAS systems arrive at the installation site pre-programmed to the customer’s specifications with the leaving fluid temperature sensors installed and wired.

Options and Components

Controls and Fans

All BOREAS cooling systems feature UL/UL-C industrial control panels custom-built by NIMBUS (UL-Certified). Panels are installed either directly on the cooling system or remotely. Controls installed directly on the cooling system are fully contained, requiring only the primary power connection on site. NIMBUS’ cooling systems feature Type 3R-rated enclosures as standard, with Type 4 and Type 4X options available.

BOREAS units outfitted with AC fans include digital controls as standard. PLC (programmable logic controllers) controls and VFD (variable frequency drive) are available as upgrades or no controls can be selected if desired. Units outfitted with EC fans come standard with PLC controls. Standard EC fan packages and AC fan packages upgraded with PLC controls and VFD provide fan speed modulation, while standard AC fan packages with digital controls feature “on/off” fan staging. AC and EC packages may be swapped at any time on select BOREAS models.

AC fan packages are available with low noise blades. This may require a motor swap to avoid potential derate of the unit capacity. Select EC fan packages offer sound attenuation modules as well.

Debris Screens

Available for any model to protect from cottonwood, hail or other detritus.
