No more ball-bearing blues

The MagLev chiller substitutes a magnetic field for ball bearings.



Major advantages of MagLev technology

• Electrical power savings of 40% to 50% over reciprocating compressor technology, 30% over more recent screw compressor technology for both air-cooled and water cooled installations.
• Carbon dioxide and particulate emission reductions from saved electrical power.
• Oil-free design, which provides the first sustainable compressor design in the air-conditioning industry and eliminates all oil-maintenance requirements.
• The MagLev chiller maintains peak efficiency throughout its useful life because there are no wear surfaces and no oil contamination of the heat exchanger surfaces.
• Eliminating refrigerant oil circulation (required in all conventional compressor technology), and its insulating effect, thereby boosting energy efficiency.
• A two amp start (in-rush) current, which is down from ~500 amps, significantly reducing electrical demand charges and materially reducing the size and fuel consumption of the standby generator.
• Claimed to have the lowest sound signature and vibration of any chiller in the industry.

New chiller range from LG Electronics

A new chiller range has been launched in the UAE by LG Electronics’ sole distributor in Saudi Arabia, H.G. Ibrahim Shaker Company. The LG RCAW series is available in a high-efficiency 50 ton to 400 ton model and a compact 40 to 540 ton model. The series offers high performance and reliability for applications in industrial and commercial markets.

“We have decades of experience in providing expert cooling solutions for our customers, and we owe it to our customers to provide energy-efficient cooling. The launch of these energy-efficient air-cooled screw chillers is a major step in this direction,” said applied product sales and marketing manager SH Lee.

These semi-hermetic, twin-rotor screw chillers feature low noise and vibration, with advanced micro-computer controls and class-leading efficiency to international ARI standards. The optimised compressor design has resulted in a smaller and lighter model that is ideal for applications where space is at a premium.

“The new chillers are suited for central air-conditioning systems in commercial, industrial and institutional applications. We have world-class technology from LG Electronics at our disposal, coupled with a huge market potential in the Middle East. We are confident that these air-cooled screw chillers will revolutionalise the regional industrial cooling sector,” said Eng. Hassan Mouthaseb, national applied sales manger at H.G. Ibrahim Shaker.

“Through our air-cooled screw chillers, we are promising our clients in the region the latest innovations in the field of cooling systems, especially in terms of energy-efficient options,” commented LG Electronics KSA GM Simon Lee.

Screw chillers are considered highly reliable due to the reduced number of moving parts. “The new range will go a long way in boosting cycle optimisation, especially for customers with varying load applications such as multiplexes, malls, offices, hospitals and hotels,” said Lee.
