Industrial Chillers

Kirloskar TURBOLEV® series of chillers uses the principle of magnetic levitation on application of an electric field, adapted to suit the chiller application.

Magnetic levitation, already a proven technology in aerospace, oil and gas exploration and transportation applications, is combined with variable-speed centrifugal compression and supported by digital electronics to run the compressor without any contact between therotating dynamic and static parts and allows the compressor to operate in a frictionless environment so as achieve the highest efficiencies.

Centrifugal compression offers substantially higher isentropic efficiency compared with other compressor designs. Used most effectively in a centrifugal compressor, a variable-speed drive further enhances part load efficiency. The combination of this technology with magnetic levitation results in a machine with an unparalleled bouquet of benefits - extremely quiet operation very high efficiency without the need of lubrication which is so essential in conventional compressors.

Magnetic Chillers recently launched a new range of Water-Cooled Chillers using first Oil Free Magnetic Bearing Centrifugal Compressor. With technical expertise to design and manufacture compressors using magnetic levitation technology, Kirloskar Chillers, have joined a select few manufacturers globally capable of offering this technology. This technology promises to dominate rotating equipment, in general and chillers in particular, over the next few decades. The company highlighted significant advantages of magnetic bearings for compressors used in chillers over conventional bearings. Chillers form a part of the central air-conditioning systems, and have a huge demand in various market segments, both Commercial – (hotels, hospitals, malls, airports and IT facilities) and Industrial applications – (pharmaceuticals, automobiles, textile, chemical & FMCG).

Glycol Chillers are a specific kind of refrigeration system, often used to cool a variety of liquids, including alcohol and other beverages. Using a chiller allows producers to lower the temperature of the product dramatically over a short period of time, depending on the production needs. Propylene glycol plays a significant role in the application of a glycol chiller. For cooling in brewing, there are few processes where decreasing or maintaining temperature are important - like crash cooling a beer after fermentation, or keeping a steady temperature during fermentation (which generates heat), or cooling the wort after an initial boiling process.

Glycol is a water-miscible coolant that is frequently used in heat transfer and cooling applications. It provides better heat transfer parameters than water, and can be mixed with water to provide a variety of heat transfer characteristics. Glycol comes in two varieties: ethylene glycol and propylene glycol. Though both materials are bad for living things, propylene glycol is most often used near food and ethylene glycol is most often used in industrial applications.

To understand the purpose of glycol, you must first understand how a chiller works. A chiller consists of two key parts: a refrigeration unit which uses electrical energy to produce a cold fluid, and heat transfer coils which move cold fluid from the refrigeration unit to the target area and hot fluid from the target area to the refrigeration unit. Typically, the target area is the inside of a freezer or some other object that you want to cool. The refrigeration unit often consists of a compressor with some compressible heat transfer fluid such as freon.

Every chiller has an operating temperature range. This temperature range is determined by several variables, the most important of which are the boiling point and freezing point of the heat transfer fluid. Glycol is prized as a heat transfer fluid because it can operate at a wide range of temperatures and can be mixed with water. The boiling and freezing points of glycol mixtures are a function of the relative amounts of glycol and water in the mixture.

Pure water freezes at 0 degrees Celsius (32 F) and pure ethylene glycol freezes at -12.9 C (8.9 F). In between, freezing points are non-linear. For instance, a solution of 10% ethylene glycol freezes at -3.4 C (25.9 F), 30% ethylene glycol freezes at -13.7 C (7.3 F) and 60% ethylene glycol freezes at -52.8 C (-63 F). The freezing point of a 60/40 ethylene glycol/water mixture is much lower than that of either pure ethylene glycol or pure water. Mixtures of propylene glycol with water follow a similar pattern, with a 60/40 mixture of propylene glycol with water having a freezing point of -48 C (-55 F).

A Cooler chiller is a device used to lower the temperature of Cooler Most chillers use refrigerant in a closed loop system to facilitate heat exchange from water where the refrigerant is then pumped to a location where the waste heat is transferred to the atmosphere. However, there are other methods in performing this action.

In hydroponics, pumps, lights and ambient heat can warm the reservoir water temperatures, leading to plant root and health problems. For ideal plant health, a chiller can be used to lower the water temperature below ambient level; 68 °F (20 °C) is a good temperature for most plants. This results in healthy root production and efficient absorption of nutrients.

In air conditioning, chilled water is often used to cool a building's air and equipment, especially in situations where many individual rooms must be controlled separately, such as a hotel. A chiller lowers water temperature to between 40 °F (4 °C) and 45 °F (7 °C) before the water is pumped to the location to be cooled.

A water-cooled chiller is one of the types of chillers that removes heat from it to cool the water used in projects or industrial or domestic structures and re-enters the water into the operation cycle. In fact, chillers transfer heat from a space that needs temperature control and transfer it to another space.
