The industrial water chiller range is designed to suit the specific needs of a multitude of industries. Some applications of chillers are to both cool and heat, these are known as a reverse cycle or a heat pump chiller. An example of this type of application would be maintaining the temperature of product being stored in a tank within a certain range, with the chiller being able to cool the product when the ambient temperature climbs during the day and heat the product when the ambient temperature falls at night. Industrial cooling applications are quite varied, therefore it’s important to match the right chiller to each cooling application like air conditioning, aqua culture, chemical, cool rooms, fruit juice, lasers, milk cooling, plastics etc.
A cooling tower is a heat rejection device which rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature. Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers.
A heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall to prevent mixing or they may be in direct contact. There are different types of heat exchangers such as shell and tube heat exchangers, plate heat exchangers, double pipe heat exchangers etc. Based on the type of flow, they are classified as parallel, counter current and cross current heat exchangers. The plates of plate type heat exchangers is either stainless steel 304 or stainless steel 316.
Tanks are a common feature in chemical industry. They are vessels in which the chemicals and/or water is stored. Tank selection is based on capacity, orientation, compatibility, and material of construction which may befibre reinforced plastic (FRP), steel or plastic. Tank capacity may vary from a few litres to thousands of litres. They are available in different shapes like square, cylindrical, rectangular etc.
Scrubbersare air pollution control devices that are used to remove particulates gases from industrial exhaust streams. Scrubbers are one of the primary devices that control gaseous emissions, especially acid gases. Air scrubbers are commonly used in process-air applications to eliminate potentially harmful dust and pollutants. Spray Towers, Cyclone Spray Chambers, Venturi Scrubbers, Orifice Scrubbers, Packed Bed Scrubbers are all different types of scrubbers which vary in terms of both function and performance. Orientation in which the scrubber liquid flows in reference to the gas flow can be cross-current orco-current or counter current. A liquid, water in general with appropriate active chemicals added, is sprayed into the air flow. The atomized liquid (typically water) entrains particles and pollutant gases in order to effectively wash them out of the gas flow. In comparison to other air pollution control devices, scrubbers are very multidisciplinary, with the ability to remove solids, mists, and gases simultaneously while also providing cooling. They are also capable of handling explosive and flammable gases safely. However, scrubbers suffer from high levels of corrosion and produce slurry waste streams which are less convenient for recycling and disposal. Scrubbers can be made of stainless steel or Fiber-glass Reinforced Plastics FRP.
Scrubbers differ based on how they are installed and where they operate.
Stationary or enclosed scrubbers are housed in their own building or enclosure. These are typically used to treat process exhaust gases from industrial waste streams before they are released into the atmosphere.
Portable scrubbers are small units used for local cleansing and cleaning applications. In addition to small size, they may have wheels or handles to make them easier to transport.
Skid or base plate mounted scrubbers are designed to be placed on a skid or plate positioned on the floor. These scrubbers frequently contain transport features such as forklift slots for movement around a facility.
Trailer or truck scrubbers are mounted on a trailer or truck for mobile spot dust or fume removal.
Fiber Reinforced Plastic (FRP) grating is a molded, one-piece fiberglass reinforced plastic grating, available in standard panels or fabricated into customized panels ready for installation. The square pattern design and one-piece construction allows load to be transferred to the adjoining bars providing a superior load-carrying capacity. The load transfer assists in load distribution on the grating as well as on the support structure.
FRP is an advanced composite made of continuous non-metallic fibers with high strength and stiffness embedded in a polymer resin. FRP grating has excellent properties such as high strength, low weight and non-susceptibility to galvanic corrosion.
Water cooled chillers and air cooled chillers are refrigeration systems used to cool fluids or dehumidify air in both commercial and industrial facilities. Chilled water has a variety of applications from space cooling to process uses. The cycle begins in the evaporator where a liquid refrigerant flows over the evaporator tube bundle and evaporates, absorbing heat from the chilled water circulating through the bundle. The refrigerant vapour is drawn out of the evaporator by the compressor. The compressor then “pumps” the refrigerant vapour to the condenser raising its pressure and temperature. The refrigerant condenses on or in the condenser tubes, giving up its heat to the cooling water (or air). The high pressure liquid refrigerant from the condenser then passes through the expansion device that reduces the refrigerant pressure and temperature as it enters the evaporator. The refrigerant again flows over the chilled water coils absorbing more heat and completing the cycle.
An axial fan is a type of a compressor that increases the pressure of the air flowing through it. The blades of the axial flow fans force air to move parallel to the shaft about which the blades rotate. In other words, the flow is axially in and axially out, linearly, hence their name. The design priorities in an axial fan revolve around the design of the propeller that creates the pressure difference and hence the suction force that retains the flow across the fan. The main components that need to be studied in the designing of the propeller include the number of blades and the design of each blade.
“Ceiling Cassette” is an indoor unit which is installed for the significant purpose. The ceiling cassette is used for the commercial purpose. It can be installed in various places such as restaurants, hotels, offices and meeting rooms. This unit has nice outlook and is equipped with manyspecial features. It has four louvers for the air circulation in all directions which in turn can maintain evenand wide cooling.
