Higher capacity magnetic chiller
JOHNSON CONTROLS IS reaching ad- vanced levels of efficiency at even higher capaci- ties with the launch of its expanded YORK YZ Magnetic Bearing Centrifugal Chiller platform.
Extending the use of magnetic bearings up to 2,020 tonnes gives more customers the opportu- nity to experience reduced driveline mainte- nance and lower operating costs.
This expansion in capacity builds on the YZ chiller that is optimized around R-1233zd(E) and utilizes an inherent series counterflow design with patented heat exchangers.
Vice president and general manager for ap- plied equipment at Johnson Controls, Laura Wand, said the advanced, aerodynamic design includes two, single-stage compressors that are paired in a series counterflow arrangement, re- ducing the lift on each compressor to improve overall full-load and off-design performance.
“The dual compressor design allows for each compressor to run individually, providing redun- dancy and improved off-design performance at lower loads,” Wand said.

High performance metal roof system
KINGSPAN INSULATED PANELS has launched K-Clad, a viable alternative to the traditional con- struction methods of non-Section J buildings.
K-Clad is a high-performing insulated metal roof system which outperforms traditional con- struction methods in terms of speed of build, thermal performance, airtightness, weather- tightness and condensation control.
Kingspan K-Clad is ideal for large-scale logis- tics and distribution buildings, as well as tem- perature sensitive environments such as cold storage and agricultural facilities.
The climate in Australia means that buildings are more often exposed to direct sunlight year- round, which greatly impacts the thermal per- formance of roof structures as well as the indoor environment and level of comfort for occupants.
Thermal modelling shows that, when com- pared to a traditional built up roof, K-Clad offers a measurable 40 per cent reduction in heat gain, resulting in a temperature decrease of more than 4.5oC between the two tested roof systems.
This significant reduction in temperature can directly improve the comfort level for building occupants.
Air leakage is also one of the biggest sources of heat loss or heat gain in buildings. K-Clad features superior, high precision joints which create un- surpassed airtight buildings, ensuring they per- form at their optimum over the life of the building.
Using a metal lining sheet instead of the foil used in traditional roof panel systems, K-Clad delivers a more robust and durable system that is also more cost effective as less steel- work is required.
Overall, the system provides a viable alterna- tive to traditional construction methods of non- Section J buildings. Available in multiple profiles, finishes, light colour options, and cover widths, the panels are easily integrated with traditional construction methods and building systems.
Using a metal lining sheet instead of the foil used in traditional systems, K-Clad is more
durable.
