Glycol heat exchanger
with unique manifold design
DANFOSS HAS BEEN working to expand its micro channel heat exchanger (MCHE) portfolio with models that are even more rel- evant to the specific sustainability challenges faced by data centres.
The introduction of new Glycol MCHE for chiller and dry cooler applications is a big step in this regard, with free cooling being a fea- ture that can have a huge advantage on both the environmental impact of a cooling sys- tem, but also the running costs.
Optimising the capacity of IT equipment and preventing expensive downtime, Danfoss MCHE facilitates ideal thermal con- ditions around server installations while optimising Power Usage Effectiveness (PUE), keeping energy consumption and CO2 emis- sions at a minimum.
In the warmer months, with outside air temperatures above 20°C, a large amount of power is required to keep IT equipment cool enough to run at its optimal level and cooling is provided by the mechanical system.
But in cooler months when air temperature drops, there is an opportunity to utilise the outside cold air as part of the cooling system.
By transferring the heat generated by the building and equipment to the outside, the low ambient temperature of the air passing over the MCHE cools the system, meaning the compressor can be stopped and power con- sumption is significantly reduced.
The Danfoss Glycol MCHE has a unique manifold design with a lower water pressure
drop than other models on the market. This greatly reduces water usage, power consump- tion and optimises peak performance.
Highly customisable connections and spe- cial bracket design make the MCHE easy to install to the unit frame. The tubes are opti- mised to perfectly balance the heat transfer and pressure from the refrigerant side.
Glycol MCHE technology can operate both independently and in combination with the refrigeration cycle.
The global head of micro channel heat exchangers at Danfoss, Jeff Tucker, said free cooling offers such a clear benefit to data centres.
“This is why we’re so pleased to be able to give OEMs a simple way to integrate it into existing designs,” Tucker said.
“With energy bills rising and the climate crisis at the forefront of minds, finding ways to innovate now will play a big role in the future landscape.
“The new technologies we are introducing are a huge step forward in helping customers meet their decarbonisation goals.”
Along with MCHE, Danfoss offers a com- prehensive portfolio for data centre cooling including compressors, valves, line compo- nents, controllers, combined with unmatched application expertise and extensive technical assistance.

Advanced fire protection system
HONEYWELL HAS LAUNCHED Fire-Lite, a suite of fire protection systems for small- to medium-sized buildings in Australia.
The easily installed solution offers cost-effec- tive, advanced fire detection and protection in new and existing buildings to help keep people and property safe.
The launch comes as Australia’s construction industry is expected to re-emerge strongly and expand by more than two per cent annually between 2023-26.
This growth, coinciding with the completion of some of Australia’s most extensive construc- tion projects, will spur demand for modern fire systems as businesses look to use technology to simplify fire and life safety management.
Honeywell Fire and Security Pacific general manager, Steve Higgins, said small- to medium- sized buildings are increasingly adopting tech- nology and features previously used in high-end applications but tailored for their unique need.
He said Fire-Lite is a globally recognised brand, well suited for this segment.
