You’ll find a reciprocating compressor in any of the ½ ton models we sell at North Slope Chillers. The majority of centrifugal chillers are water chillers (It’s extremely rare that you’ll find a centrifugal system in an air chiller). ShenChuangYi Refrigeration Equipment Co., Ltd is a professional manufacturer in making water-cooled chillers, air-cooled chillers, industrial chillers, low-temperature chillers, etc. A picture of the data plate will give us the kind of refrigerant and how many systems. A picture of the chiller will familiarise us with the chiller itself. All this info will assist us in putting together a package for your needs.
These fans represent the main difference between air cooled and water cooled chillers. As they move air across the condenser, unwanted heat is removed from the system so the cycle can start all over again. Air cooled chillers are located externally to a facility and have condenser coils cooled by fan-driven air. Water cooled chillers are usually located internally and water is recycled to a heat sink or external cooling method. The external cooling method can include a cooling tower or in some cases, a water fed cooling system, which is more efficient at heat rejection. Water Cooled chillers are also used frequently to refrigerate facilities of all kinds, cooling products and machinery among other applications. Water Cooled chillers often are used with a cooling tower or adiabatic system. Our TECOCHILL® “RT Series” product line offers air-cooled engine-driven packaged chillers with 50 tons of cooling capacity.
Air cooled chillers are versatile workhorses that provide cooling power to both small and large operations. Their compact design makes them portable, easy to install, and inexpensive to maintain. Let’s closely examine the inner and outer workings of air cooled chillers. In most air conditioning systems geared for cooling, the principal refrigerant is chilled water. Air passes through a coil of chilled liquid and the heat is transferred from the air to the chilled water. The chilled water is cycled through so that chilled water is always present as air comes through.
A case study on the secondary loop refrigeration system with the cooling efficiency lifted by high-performance brine chillers and evaporative condensers. Kaltra made available its Lightstream Freecool chillers now with refrigerant R513a in capacity range from 600 to 1250kW.

The answer to your industrial equipment and process cooling needs. These complete package units can be configured as portable or central chillers. Our Packaged Chillers are just that – complete packaged chillers that include a large volume glycol reservoir, all required system pumps, and operational controls. Once the chiller is on site, the installation is limited to connection of the main power as well as the process cooling loop . Selection of chiller depends on so many factors like cooling capacity, overall cost, operating location & availability of water at that location. At Whaley Products, Inc. we manufacture quality industrial cooling systems for a wide range of processes and applications. A commitment to precision engineering and innovative design have made Whaley Chillers the choice of Industry Leaders. This unit is packaged chiller equipped with casters for simplified portability.
Each chiller is custom built to efficiently support your specific process cooling requirements. The industrial series chillers can accommodate a large range of process supply temperatures while operating in a wide range of ambient temperatures. This is because water cooled chillers produce lower condensing temperature than air cooled chillers. Refrigeration compressors are essentially a pump for refrigerant gas. The capacity of the compressor, and hence the chiller cooling capacity, is measured in kilowatts input , Horse power input , or volumetric flow (m3/h, ft3/h). The mechanism for compressing refrigerant gas differs between compressors, and each has its own application. Common refrigeration compressors include reciprocating, scroll, screw, or centrifugal. These can be powered by electric motors, steam turbines, or gas turbines. Compressors can have an integrated motor from a specific manufacturer, or be open drive--allowing the connection to another type of mechanical connection. Air-cooled and evaporative cooled chillers are intended for outdoor installation and operation.
Short term, long term, chiller, generator, or portable AC unit, we have the fleet and people where and when you need them. Air-cooled chillers are used in the chemical fiber industry to freeze and dry air to ensure product quality. The air-cooled chiller can control the temperature of the vacuum coating machine in the vacuum coating industry to ensure the high quality of the coated parts. Teyu recommends CW-5200 water chiller to cool turbomolecular pump. After the careful consideration, the customer finally chose CW-5200 water chiller. Based on its installation experience and technical expertise, Kaltra was selected to assist in the development of a chilled water plant for LPG recovery facility. German chiller manufacturer, Kaltra Innovativtechnik, is set to showcase its new Easystream family of air- and water-cooled chillers with scroll compressors. Trending Turbocor based chiller family by Kaltra has been extended with highly efficient models with energy efficiency ratio of up to 4.30. A case study for the replacement of the air conditioning chiller with high-efficient inverter unit with a free cooling system. Kaltra deployed a central air conditioning plant based on highly efficient chillers with sequencing for a large commercial building in Canary Wharf, London.
You might need to use chillers with multiple compressors that can work independently from one another so that if 1 compressor fails the chiller can still remain partly operational. Instead you should use multiple chillers, in parallel, of different sizes to meet the changing seasonal load at optimal performance with redundancy built in. For example you have a building with a cooling load of 2,200 Tons, then you should use combinations such as two 1,200 ton chillers or two 900 tones and a 500 ton or a 1,000 ton and two 700 ton chillers etc. Vapor absorption chillers will use a heat source to move the refrigerant around the system rather than using a mechanical compressor. The refrigerant in these chillers move around between areas of different temperature and pressure. Arrived in March 2014 to KIG were four immaculate Trane RTAA 125 ton chillers. Removed from a local Data Center where it was used relatively minimal, and the Data Center has been shut down.

Note that efficiency requirements differ by full- and part-load optimized applications. For long-term business development, air-cooled chillers are a better choice compared to water-cooled chillers as air-cooled chillers are more conducive to the environment and they cost less regarding their maintenance. TopChiller will give you a full air-cooled chiller solution and refrigeration design once we have collected all your answers to the above questions. because some special industry needs special treatment, like food or beverage, we must use food-grade stainless steel material. Air-cooled chiller product categories are also very clear and serve as a helpful tool to locate the product type you desire. A reliable manufacturer of high-quality air-cooled chillers can save you a lot of time, money, and energy. When the air-cooled chiller is in normal operation, the high pressure is 11-17kg, and the low pressure is 3-5kg. In the shutdown state, the high pressure and low pressure are all-around 0.6kg. The air-cooled chiller was originally designed with multiple protection devices, which have played a significant role in the use.
