Hybrid cooler features heat transfer technology
BALTIMORE AIRCOIL COMPANY (BAC) has introduced the Nexus Modular Hybrid Cooler, the world's first intelligent, plug-and- play, modular, hybrid fluid cooling system.
The Nexus is engineered to simplify system design and optimize water and energy sav- ings, while providing the lowest installation, operating, and maintenance costs.
It will be available in Australia in 2020, the company told CCN.
The Nexus Modular Hybrid Cooler simpli- fies both the design and installation of fluid cooling systems.
The units are up to 8 feet shorter in height, have a 40 per cent smaller footprint and are 35 per cent lighter than traditional fluid coolers. Modules are designed to be moved with a pal- let jack and fit in a freight elevator – eliminat- ing the need for special rigging equipment.
Structural steel requirements can be re- duced by up to 50 per cent, and permanent ladders or elevated platforms can be eliminat- ed. All fans, pumps, accessories and controls are factory installed, and wired, for true sin- gle-point wiring.
BAC’s patented Heat Transfer Technology delivers exceptional heat transfer perfor-
mance, durability, and longevity in a com- pact, corrosion-resistant package that has 65 per cent less internal fluid volume and re- quires no passivation. The Nexus Cooler’s new, patent-pending DiamondClear design uses 60 per cent less spray water volume than traditional systems, has turbulent spray wa- ter flow, and the spray water basin can be in- spected while in operation.
BAC’s innovative iPilot Control System with patent-pending, embedded intelligence minimizes operating cost by effectively bal- ancing water and energy savings based on customer needs and preferences. The EC Fan System provides superior efficiency as well as high external static capability, with a direct- drive radial fan and a variable-speed electri- cally commutated (EC) motor. It completely eliminates maintenance associated with tra- ditional fan drive systems and delivers supe- rior reliability.
The Nexus Modular Hybrid Cooler has the highest uptime and reliability. As standard, it is a passivation-free unit with premium non- corrosive materials to stay up-and-running at the most critical times. A non-combustible option that meets the most stringent fire codes will also be available.
BAC President, Don Fetzer, said the product highlights the company's leadership when it
comes to innovation. “We have created the world’s first truly smart hybrid cooling solution, with the ability to switch between evaporative and dry cooling in a modular compact foot-
print,” he said.

Testing for leaks and flow
CETA TESTSYSTEME GMBH, a manu- facturer of leak and flow testing devices, has more than 30 years of experience in in- dustrial testing technology.
Compressed air and hydrogen are used as test media. The size of the products test- ed for tightness ranges from small-volume microswitches with a volume of 0.1 ml up to tanks of 1,000 l capacity. Depending on the application, CETA leak testers with gauge pressure or differential pressure sen- sors are used. Available pressure ranges are between -1 and 30 bar up to 400 bar with the pressure rise method (e.g. testing of in- jection valves).
In addition to leak testing, there are prod- ucts that are tested for flow. With the CETA flow testers, a range from 3 ml/min to 200 l/ min can be measured with different lami- nar flow elements. Typical products of which the flow rate is tested are pipes, cool- ing channels, valves, exhaust systems and membranes.
Well-known customers from the automo- tive industry, fittings, heating and air condi- tioning industries use the CETA test devic- es for quality assurance and to secure production.
The CETA test instruments are delivered with a warranty of 3 years, with the optional extension to 5 years.
