Turbocor Chiller

Turbocor Centrifugal Water Cooled Chiller

Introducing water cooled variable-speed centrifugal chillers with magnetic bearings from Blue Star, India’s largest central airconditioning and commercial refrigeration company.

Blue Star has been developing and manufacturing chillers for various applications and providing expert cooling solutions for over six decades. All the products manufactured by the Company are energy efficient. In line with its corporate philosophy of launching innovative products, Blue Star introduces centrifugal chillers with oil-free technology, manufactured at its own world-class factory.

These centrifugal chillers are highly energy efficient and are equipped with the new generation centrifugal compressors with magnetic bearings. These two-stage compressors, coupled with the in-built Variable Speed Drives, enable significant reduction in the operating cost as well as reduce emissions.

Blue Star water cooled centrifugal chillers offer the highest sustainable efficiency with low maintenance and are ideal for data centres, hospitals, hotels, green buildings, educational institutions, as well as industrial and process applications.

Highly energy efficient

  • While the in-built VSD allows centrifugal chillers to perform at part loads, the two-stage centrifugal design of the compressor ensures its performance even at full loads. Moreover, the IPLV is as low as 0.34 KW/TR. This substantially reduces operating costs.

Oil-free technology

Conventional flooded evaporator designs use oil for lubrication. This oil frequently migrates to the evaporator. Once it is in the evaporator, it can form a coat on the tubes. This affects the heat transfer ability of the tubes. Moreover, the efficiency drops considerably given the concentration of oil in the refrigerant. There can be up to 8% drop in efficiency on account of 3.5% oil content in the refrigerant. While many chillers incorporate oil recovery devices or have designs to minimise the oil loss, the ideal way to avoid oil contarmination is to eliminate oil all together.

The need for oil in centrifugal chillers is completely eliminated. With Blue Star water cooled centrifugal chillers you don’t need oil pumps, oil reservoirs, oil coolers, oil filters, oil relief valves, oil system controls, starters, piping or heaters. As a result, there is no need for oil samples, oil filter changes and leak detection. All in all, the oil-free technology makes these chillers highly efficient and reduces maintenance dramatically.

Eco-friendly

Blue Star water cooled centrifugal chillers incorporate the eco-friendly refrigerant R-134a that has zero ozone-depletion potential. On an average, a 90 TR centrifugal chiller yields an annual CO2 emission reduction of over 53000 lbs.

Low noise and vibrations

Low-noise design eliminates the need for acoustic enclosures. The high-speed design reduces vibrations transmitted to the system.

Compact design

The footprint of the chiller is small, as compared to conventional chillers of the same capacity, thanks to its weight and size. The chiller is also easy to handle.

Turbocor Compressor

This chiller incorporates a two-stage centrifugal compressor, Turbocor. Unlike a conventional compressor, Turbocor is an intelligent, oil-free compressor with magnetic bearings, pioneered by Danfoss-Turbocor.

Here are some of the compressor features:

  • The compressor has a bigger operating envelope compared to other conventional compressors and is protected via integrated electronics. The compressor is self-correcting and incorporates a system of self-diagnostics, monitoring and control.
  • While conventional compressors of the same capacity require 500 to 600 amperes to start, Turbocor requires only 2 amperes. So the generator required is smaller in size and so is the size of the electrical cable and isolator.
  • The compressor has an in-built VSD which automatically controls the compressor's speed as per the required load and operating conditions, thereby making it highly efficient.
  • The compressor speed ranges from 18000 rpm to 48000 rpm. This high speed design minimises the vibrations considerably.
  • In the event of a power failure, the compressor motor acts as a generator, providing power for the bearing control system. It also has a unique system to de-levitate the shaft.

Highly efficient scroll compressor

Time-tested scroll compressors are used in these chillers, which are highly energy-efficient. This results in higher reliability as well as lower power bills. These compressors are suction gas-cooled, fully hermetic and provided with a crank-case heater.

Multi-compressor advantage

The presence of multiple compressors helps the system in two ways: there is built-in redundancy adding therefore to reliability; and it allows for capacity modulation by switching on only as many compressors as will be required at any time to suit part-loads, thereby increasing efficiency.

Quick to install

Blue Star Process Chillers come pre-fitted with insulated chilled water tank and chilled water pump. The units also come fully wired, refrigerant charged, and tested from factory before dispatch. In the field therefore, only chilled water and electrical connections need to be made before the system is ready for commissioning.

High-efficiency heat transfer

The condensor calls on these chillers have super-slit aluminium fins, with internally finned copper tubes. Fins are optionally coated with anti-corrosive blue-coating. All these measures increase heat transfer and improve efficiency, while preventing corrosion tου
