Several operating concerns including inefficient energy use and high maintenance costs initiated the need for a chiller replacement at Sun-n-Sand in Shirdi, India. Oil-free Magnasmart Chiller from Blue Star Ltd. using Danfoss Turbocor® compressors was chosen as a replacement. Operating costs were drastically reduced when this air-conditioning system was upgraded. Sun-n-Sand is a leading group of five star hotels which strives to serve both business and leisure travellers. The Mumbai property is the flagship hotel of the Sun-n-Sand group and was commissioned in 1962.
“Noise and vibrations are critical for hotel applications”, said Mr. Rajesh Advani, Managing Director of the Sun-n-Sand Group, and continued, “I am impressed with the 73dBA sound level of the running machine which allowed us to re-occupy the office space directly below the chiller room.”
“Blue Star´s Magnasmart chiller with oil-free centrifugal compressor technology boosts energy efficiency and cuts operating costs,” said the plant operator at Sun-n-Sand. “It provides much better efficiency compared to the old unit, and we are all very pleased with the smooth and efficient operation of the new Magnasmart chiller.”
Mr. Shinde, Sun-n-Sands facility manager, added: “Total costs to run the air-conditioning plant decreased drastically. We are saving approximately 200,000 to 250,000 INR (US$3,200 to 4,000) per month”. Payback was within 18 months.
On top of the energy savings and quiet operation, the staff at the hotel is pleased to see further advantages of the Magnasmart chiller with Danfoss Turbocor® compressor over their old cooling units.
- Considerable smaller foot print of the Magnasmart chiller compared to the absorption machine.
- On board inverter reduces the starting current of the compressor to only 2 amps.
