by Brianna Crandall — July 24, 2020 — Baltimore Aircoil Company (BAC), a global manufacturer of heat transfer products and services, recently announced enhancements to its innovative Nexus Modular Hybrid Cooler, an intelligent plug-and-play modular hybrid fluid cooler for HVAC and light industrial applications. The Nexus Cooler, which was already exemplary for low installation costs, low operating costs, low maintenance costs and maximum uptime, now provides top-level water quality resulting from enhanced water management, says the company. An optional water disinfecting system is now available, and the product has been redesigned to meet stringent local building codes regarding fire safety and noise reduction.
The BAC Nexus Modular Hybrid Cooler was designed to minimize maintenance cost by reducing spray water volume by up to 60%, by allowing accessibility to all components at the front of the unit, and by operating dry when temperature and climate allow. It also reduces water treatment costs with its DiamondClear Design, which is engineered to prevent stagnant water in the system and minimize scale buildup and biological growth. The new optional, compact and fully integrated ultraviolet (UV) water disinfecting system rounds out the product’s enhanced water management system. This UV disinfecting system further minimizes bacterial growth, delivering water quality and enhancing health and safety, all without changing the unit’s footprint.
BAC points out that corrosion-resistant, premium materials are standard on the Nexus Modular Hybrid Cooler, reducing the need for maintenance, while fan and motor redundancy reduce unplanned downtime. There is no need for permanent ladders or elevated platforms to perform routine maintenance, making the Nexus Modular Hybrid Cooler safer overall than competing products, claims the company. Additionally, new optional accessories are now available to further reduce sound levels and help comply with stringent fire codes and sound requirements.
The Nexus Cooler’s simplified system is designed to deliver a 15% reduction in system costs compared with traditional fluid coolers. Nexus eliminates the need for a separate heat exchanger or controls, and it delivers reduced water treatment requirements, with no sweeper piping or side-stream filtration required. The system’s compact design makes it suitable for constrained spaces, including indoors. This compact design also reduces installation costs, as modules can fit into a freight elevator, thus eliminating the need for cranes or helicopters, points out the company.
The innovative hybrid cooler is also engineered to offer up to 50% water savings and 40% energy savings. The iPilot Control System automatically switches among three modes — fully evaporative, fully dry, or balanced “Nexus mode” — according to environmental conditions, operating priorities and cooling demands. The Nexus Cooler is highly efficient thanks to the patented hCore Heat Transfer Technology and a direct-drive, variable-speed EC Fan System, adds the company.
