Ensuring an excellent finish

Blue Star's production facilities use raw materials that are of the highest quality, including corrosion resistant, galvanid steel for enhanced life and rust protection. The equipment used to process the steel include CNC machines such as the Amada punch press, hydraulic press and specialised microprocessor-based protection and resistance welders. All these machines ensure superior quality in cabinet fabrication to tight tolerances.

All products are powder coated by specialised process equipment from Nordson of the USA on fully conveyorised lines. These equipments are fitted with electro-mechanical oscillators that ensure an even powder coating. A 'smart spray' mechanism senses movement of the conveyor and geometry of the component to adjust powder flow.

Blue Star is equipped with a high-tech coil manufacturing setup using imported Burr Oak machines that can manufacture high-efficiency plain coils as well as enhanced split fins for superior heat transfer. The cooper tubes are then processed by a bank of PLC-controlled Burr Oak machienes that ensure perfect bonding between the cooper tubes and fins for superior performance. The coils are then tested for fine leaks with ultra-sensitive electronic leak detectors to enhance reliability.

A typical residence of two bedrooms and a living room requires 4.5TR (3 x 1.5TR) of airconditioning. However, only two rooms are occupied at most points of time. Traditionally this means installation of three ODUs and three IDUs, each of 1.5TR capacity, occupying more ODU space resulting in clutter and spoiling the facade.

With Multi Inverter Split AC, you need to install only one ODU that drives up to three 1.5TR IDUs. The system feeds the two working IDUs at most points of time, thus optimising use of capacity and saving both investment and running costs. It is also designed to ramp up the capacity and maintain comfortable indoor conditions in all three rooms, if all three IDUs are switched on at the same time on rare occasions. This makes it ideal for large villas, big row houses and other multi-room applications.

Moreover, the refrigerant used is the eco-friendly R410A which minimises the emission of Ozone Depleting Substances.

Blue Star, India's Largest central air conditioning company has been providing expert cooling solutions for over six decades. it has been manufacturing a wide range of chillers for over two decades. Drawing from this expertise, Blue Star presents a wide range of air cooled screw chillers with environment-friendly R134a refrigerant.

These chillers are manufactured at Blue Star's own ISO 9001 certified factory with the chiller test bench certified by Air conditioning, Heating and Refrigeration Institute(AHRI). Blue Star screw chillers are equipped with effective capacity control, They provide excellent efficiency making them ideal for varying load applications such as office spaces, hotels, hospitals, malls and multiplexes.

Air Cooled Screw Chillers from Blue Star are available in two series:

• Series I: 375 to 635 KW (AHRI-certified series)-5 models in capacities of 375,525,555,625 & 635 KW. This series has been certified by AHRI.
• Series II:495 to 1395 KW - 9 models in capacities of 495,765,875,915,985,1055,1155,1255,1395 KW.

Compressor

The salient features of these compressors are:

• Highly efficient and low noise levels.
• Due to few moving parts and slider valve, these compressors have minimal wear and tear, thereby, resulting in longer life of the compressor.
• This compressor has stepless capacity control, from 25% to 100% making it suitable for varying load applications and efficient under part load conditions. The capacity control also helps in limiting the starting current and the loading is done steplessly.
• Due to its inherent characteristics, screw compressor has the highest volumetric efficiency and derating at higher temperature is negligible.
• Each compressor has the latest 5 to 6 patented profile design with separate radial and axial force bearings, built-in oil separator, PTC motor winding protection,discharge temperature protection with its controller, oil level switch and oil differential pressure switch. This guarantees reliability and long life of bearings under heavy working operating conditions.

Economiser

Refrigerant liquid-to-liquid plate type heat exchanger is provided for the Economiser system. The liquid refrigerant is sub-cooled to enhance the capacity, thereby reducing specific power consumption (IKW/TR) and enhancing the Coefficient of Performance(COP).

Cooler

The shell and tube evaporator has been built using imported, internally enhanced and highly efficient finned copper tubes and has been optimised for refrigerant and water velocities. The expansion of the tube is done with torque controlled process.

Air Cooled Condenser

• Fin and tube condensers are manufactured using Super Slit aluminum fins. The cooper tubes used are inner grooved type with higher height trapezoidal cross section to increase the internal surface area of heat transfer.
• Hydrophobic coated fins can be manufactured as an optional feature which give corrosion resistance, typically 3 to 5 times more than the uncoated fins, depending upon the ambient conditions. The coated fins are tested for 500 hours of salt spray test.

Liquid Injection

The refrigerant suction gas cools the winding of the semi-hermetic screw compressor motor.During the part load operation where the suction gas circulation is less, as a precaution, liquid refrigerant is injected into the suction side of the compressor to cool the motor winding. This is done to keep the motor winding temperature within limits. it is provided as a standard feature to enhance the life of the compressor.

Fans

The chiller is incorporated with 5-lobe, bird-wing design fans. This profile optimises the noise level as well as power consumption against the required airflow and static pressure.

Spring Isolators

Specially designed spring isolators are supplied along with the units to minimise the transmission of vibration.

Acoustic Enclosure

An acoustic enclosure can be optionally provided for the compressor to reduce the noise levels.

Electronic Expansion Value

The units are incorporated with electronic expansion values for precise control of refrigerant flow through the cooler to accurately maintain the desired superheat. The expansion value is very sensitive to load variations and adjusts the flow of the refrigerent with short response times to achieve power savings. The microprocessor-based control panel provides the signals for accurate operation of the expansion value based on the superheat.

Microprocessor Control Panel

• The cooler outlet temperature can be controlled accurately within a tolerance of ± 0.5℉.
• In-built time delays for compressors and condender fans, single phase/phase reversal protection and anti-freeze protection.
• Password protection at three levels.
• RS 232 and RS 485 ports for remote connectivity,fault indication and status facility.
