NIMBUS Innovation Saves Water for Process Cooling Systems

While the U.S. has far fewer foundries than India, China, and Japan, this country is still the second-largest global producer of cast metal. That’s because North American foundries continually modernize and improve efficiencies.

Some of these efficiencies are created in part through innovative fluid cooling systems developed by NIMBUS. Over the past ten years, this Alabama-based firm has been committed to improving fluid cooling equipment for foundries. Now, it’s applying that technology to a range of vertical markets in new and exciting ways.

Benefits a Range of Industries

Although the products were developed with foundries in mind, NIMBUS technology can benefit a range of industries. Jerry Petit, Director of Business Development at NIMBUS, reports, “We manufacture fluid cooling equipment that cools other equipment. There’s a wide variety of commercial HVAC equipment, such as chillers and water source heat pumps, that we can cool.”

“We also manufacture adiabatic coolers,” he adds. “NIMBUS pump skids help pump the fluid through the system and keep it going. But what makes us really special is our ability to save water and energy.”

NIMBUS is a "Blue" Company

Petit explains, “Some companies call themselves ‘Green,’ but we call ourselves ‘Blue.’ This is because NIMBUS uses significantly less water to cool equipment than traditional evaporative open and closed cooling towers.”

While green building has been on the radar for decades, many companies and governments are now becoming more aware of the need to use less water. “The entire West Coast has been in and out of drought conditions for decades,” Petit says. “One vertical that has been hit pretty hard is the wine industry. Wineries have traditionally used a lot of water, but that’s a challenge in drought conditions. Open and closed evaporative towers both use a lot of water on an annual basis. The NIMBUS Virga Adiabatic cooling systems use about 80% less water than traditional evaporative cooling towers, which translates into huge savings.

Drought is becoming more common in the West and in other parts of the country. “The cost of water is going up,” notes Petit. “It’s now being recognized as one of those resources that demands conservation. We’re all familiar with the importance of being energy-efficient. I think water is now the focus of environmental efforts. Some water authorities are regulating water use. We want to find ways to save water, and that’s where our technology comes into play.”

VIRGA Adiabatic Cooling Systems

VIRGA III® and VIRGA X3® are hybrid adiabatic cooling systems that reduce water consumption by up to 95 percent compared to traditional fluid coolers. In addition, they eliminate standing water in favor of a fully closed coolant path and augment it with fresh water to support the system’s cooling capacity on the hottest days of the year. This hygienic closed system also reduces the growth of bacteria that causes Legionnaire’s disease.

“Healthcare and pharmaceutical customers appreciate adiabatic cooling,” Petit explains, “because it significantly reduces the chances of bacterial growth in your equipment.”

He adds, “These cooling systems use a small amount of water to lower the ambient air temperature being drawn across the coil which increases the heat rejection capacity. And when it’s cold out, there’s no need for water use, so the unit operates as a dry air cooler, eliminating freezing or ice buildup.

BOREAS® V-Series Dry Air Cooling Systems

The BOREAS dry-air cooling system was designed for lower dry bulb temperatures or higher outbound process fluid temperatures.

“BOREAS has a V-Shape, which means it requires a smaller footprint than traditional dry coolers,” Petit adds. “And it uses fan staging to reduce energy consumption.”

BLUEDRIVE® Coolant Circulation Systems

Petit explains that BLUEDRIVE comes on a skid to work alongside VIRGA and BOREAS coolers. “BLUEDRIVE pumps can be customized to the owner’s needs.

Energy Efficiency

While NIMBUS is known for reducing water consumption, it can also save energy in many applications. Petit says, “With our technology, customers can also shut down other pieces of equipment, such as chillers in winter, and that can save a tremendous amount of energy.”

“We’re able to reduce water consumption and, in many cases, reduce energy consumption as well,” Petit comments. “That also makes us a good choice for universities and higher education looking for green, or blue, energy options.”
