A Chiller is thermal refrigeration equipment which has found its applications in a wide range of industries. The commonly found use of chillers is for usual product refrigeration and dehumidification. Machinery cooling is also a widely applied domain in chillers’ usage. It works on basic thermodynamic vapour-compression or absorption cycle. The fundamental principle on which chillers work is its ability to transfer heat from one location to another.

Types

Chillers can be divided into different types depending on the factor of categorization. But majorly they are differentiated as follows-

  • Vapour compression
  • Vapour absorption

Among these vapour compression chillers are most common and include

  • Air chillers
  • Water chillers
  • Evaporative condensed chillers

These are then divided into subcategories based on compression technology – Centrifugal, Scroll, Screw, and Reciprocating

The most commonly available chillers are air-cooled chillers and water-cooled chillers.

These differ on the basis of how heat is removed from the system after being transferred from the system to be cooled

Air Cooled chillers – Fans are used to remove the heat.

Water Cooled Chillers – Water is pumped and dispersed throughout the system.

Chillers are also divided according to their capacity.

Here at DANA, we are determined to bring to you high-quality refrigeration solutions including chillers with capacity ranging from 5TR to 100TR. With a supply base consisting of countries like Bahrain, Oman,  Kuwait, Saudi Arabia, Jordan, UAE and Africa, DANA has been producing and supplying chillers for the almost past couple of decades, giving us a stronghold over the market

Air-cooled Water Chillers (Air Chillers)

Components

A water cooler comprises of four components which have their individual functions completing the thermodynamic cycle. These are

  • Evaporator
  • Compressor
  • Condenser
  • Expansion valve

Working

Air and water-cooled chillers both work on similar thermodynamic mechanisms. The difference between them strikes only when we talk about removal which is a process, they carry out differently as their names suggest. The basic idea is to force the refrigerant throughout from compressor, which then passes through condenser, expansion valve and then evaporator and back to the compressor. The difference as mentioned above comes when we talk about the way the heat escapes which is through fans in air-cooled chillers and through the water in water chillers.

DANA brings to you efficient and reliable air-cooled chillers for application ranging up to 100TR.

Pros

  • Air Chillers are compact and do not require much space hence they can be kept on the roof and mechanical room is not required. This ensures more area for other purposes.
  • They do not require water and hence find better application in areas which are drought-stricken or are facing water scarcity.
  • Installation is cheaper as they make use of minimal equipment.
  • These type of chillers are much more efficient and favourable when maintenance is considered because of less equipment having lesser maintenance cost and more life.
  • Work much better in humid condition.
  • They have a very simple design and hence installation is less complicated.

Air Chillers – Centralized Vs Decentralized operation

For industrial applications, chillers can work in a centralized fashion, where a single chiller serves multiple cooling needs, for relatively smaller sized industries, decentralized chillers may be used (Each machine has its own chiller)

Many industries also use a combination of both centralized and decentralized chillers, since each approach offers its own set of advantages.

As mentioned earlier, decentralized chillers are used when a smaller cooling capacity is desired (0.2 to 10 tons). Centralized chillers are used for plants with relatively larger cooling requirements (10 tons to 100 tons)

Industrial Applications (Air Chillers)

  • Industrial chillers are used for controlled cooling of products, mechanisms and also factory machinery in a wide range of industries.
  • Their applications spread over a wide spectrum of industries including plastic industries, metalworking industries, casting industry, pharmaceutical formulation, food and beverage processing, paper and cement processing, vacuum systems, power generation systems.
  • Air-cooled water chillers are generally intended for outdoor installation and operation. Air-cooled machines can directly be cooled by ambient air being mechanically circulated through machine’s condenser coil to expel heat to the environment.

DANA water chillers’ salient features

DANA Chiller range

  • Built over a large cooling capacity range – 2TR (24,000 BTU/hr.) – 100 TR (1,200,000 BTU/hr.)
  • Superior corrosion resistance due to heavy-duty thick gauge galvanized & epoxy powder coated body.
  • Robust construction to ensure that chillers can withstand the heavy summer heat of the gulf region.
  • Chillers with a capacity less than 3TR (Ton Rating) run on a single-phase electrical supply.
  • Air Chillers with a capacity greater than or equal to 5TR (Ton Rating) run on the three-phase electrical supply.
  • Properly designed axial discharge fans – for low noise levels and high efficiency.
  • Equipped with built-in integrated Centrifugal Circulation Pumps
