Its proven design is used in thousands of BAC adiabatic units across the globe with millions of run hours. One of the reasons for its widespread usage is that the product is resilient in cold weather, running dry in sub-freezing tempera- tures to achieve reliable year-round operation. Continuous performance is facilitated by redun- dant fan and water distribution systems for maximum reliability.
Installation of the TrilliumSeries Cooler is quick and simple. Its single-piece lift requires no field assembly, allowing for easy rigging. The product provides an assured fit, with an up to 20 per cent smaller footprint when com- pared to other adiabatic solutions. Controls are pre-programmed at the factory and have a full- colour touchscreen that provides an intuitive user experience. Its single-point power con- nection and seamless BMS integration ensure fast installation.
Maintenance of the TrilliumSeries Cooler is easy with access to all components from the outside of the unit. There are large doors to reach the water management system and the easy to remove pads enable quick service. Au- tomatic cleaning of the coils and pre-cooler pads by running the fans in reverse maintains peak performance. These features improve sys- tem reliability and longevity while offering peace of mind.
BALTIMORE AIRCOIL COMPANY (BAC) has released its new TrilliumSeries Adiabatic Cooler, which is ideal for applications that de- mand a combination of energy efficiency and limited water use.
BAC’s innovative design maximises both wa- ter and energy efficiency, ultimately minimising costs. In addition, the TrilliumSeries Cooler is designed to make installation and ongoing maintenance simple.
What distinguishes BAC’s TrilliumSeries Cooler is that it captures and reuses water, un- like once-through systems, and is optimised for adiabatic operation, a form of heat rejection that is more efficient than dry coolers and uses less water than evaporative cooling.
This cooler can operate at a high dry switch point and offers up to 20 per cent energy savings versus alternatives in the marketplace, thanks to its smart water management system comprised of high-efficiency pre-cooler pads, a dual pump recirculating system, and intelligent controls.
High-efficiency pre-cooler pads are one com- ponent of the TrilliumSeries Cooler’s water man-
agement system, specially developed with a unique anti-stick, anti-algae growth, and UV re- sistant coating to extend the life of the pads and deliver maximum heat rejection.
In addition, this new product contains a dual pump recirculating system to ensure code com- pliance with ASHRAE Standard189.1, which for- bids the use of once-through systems, and that water is re-used rather than sent directly to drain.
“THIS COOLER CAN OPERATE AT A HIGH DRY SWITCH POINT.”
Lastly, intuitive, and intelligent controls con- tinuously optimise operation based on real time weather and load conditions. Multiple pre-set modes of operation allow for operation that best fits the application at hand. These components work together to maximise water savings and achieve up to 20 per cent energy savings.
Immersion temperature sensors for cooling
Even the smallest fluctuation in temperature can impact running costs.
TO SUPPORT THE growing demand for unin- terrupted data, Vaisala, has launched a new product for data centres – the TM 110 tempera- ture transmitter.
Vaisala’s product manager, Anu Katka, said the TM 110 is a great addition to its product portfolio. “Customers can source all of their most im- portant sensors from one supplier – air tempera- ture, humidity and differential pressure sensors for rooms and ducts, outdoor weather sensors, and now immersion temperature sensors for
cooling systems,” Katka said.
“Cooling is critical to maintaining tempera- ture and humidity at the optimal level for reliable server operations. The TMI 110’s accuracy is ±0.1 °C, which is really good news for data cen- tre operators as well as for the environment.
“Even the smallest fluctuation in cooling temper- ature can have a significant impact on the overall running costs and environmental impact of energy hungry data centres,” Anu Kätkä concludes.
The new immersion type Vaisala TMI 110 Tem- perature Transmitter is supplied with a calibration certificate and offers excellent response time.
