Water Chiller Solutions A solution to every water cooling need.
During the harsh summers of Middle East, the ambient temperature is very high and it can go up to as much as 52 o C. Naturally, in such conditions, the temperature of water in tanks rises steeply. Thereby affecting various commercial and residential applications. Here, the need for cool water becomes critical. Be it for large hotels or small villas, or for bathroom applications or drinking purpose. To cater to these diverse needs, Blue Star, India s largest central airconditioning and commercial refrigeration company, introduces yet another cooling solution: a unique range of water chillers that provide cool water which is safe and hygienic. These chillers are designed for applications that vary from small domestic requirements to larger requirements as in hotels. And they incorporate plate type heat exchangers that are far superior to conventional systems that use copper coils. Thus giving the following advantages: Safe and hygienic water High corrosion resistance due to use of SS 316 or SS 304 High pressure up to 45 bar High thermal efficiency High working temperature Low maintenance Blue Star has been offering expert cooling solutions to various corporate and commercial customers for over six decades. At the core of this expertise lies a strong understanding of the market, robust R&D and superior manufacturing skills. And it is with this expertise, Blue Star now brings to you four different types of Water Chiller Systems for your diverse needs.
Overhead Tank Chiller Overhead Tank Chillers are ideal for locations where a large quantity of cooled water is utilised. The nominal cooling capacity of these chillers varies from 3 to 7 TR and cater to water cooling needs of large hotels, villas and buildings. Placed generally on rooftops, these chillers cool water in the main reservoir tanks and are essential during the harsh summers of Middle East. The Overhead Tank Chiller is a plug-and-forget solution that comes fully equipped with accessories like pumps, strainers and flow-switches. Attached to the main reservoir, it continuously cools water and maintains it at 28 o C to 30 o C. This cooled water is then supplied to different outlets for various applications, whenever required.

Domestic Water Chiller / Aqua Chiller Domestic Water Chillers are compact chillers as they occupy lesser space. They are used in places where an existing system such as a purification system or a boiler is already in place. These chillers are best suited for villas and apartments. Connected to the main storage tank, Domestic Water Chillers cool water effectively even during peak summers. The set-up is similar to the Overhead Tank Chiller and accessories like pumps, strainers and flow-switches are provided separately, if required. Water is cooled to 28 o C to 30 o C and can be used for a host of applications in bathrooms, kitchens and other outlets.
