And the Pathfinder is 100% configurable, customized to meet the size and performance needs of each application. Available from 100 to 565 tons, Pathfinder is a fit for a broad range of applications. Now we come to the topic of air cooled chillers, Air-cooled chillers are the most popular compared to other types of chillers because of easy operation and low maintenance costs. This protection makes sure all air cooled chillers have an outstanding cooling performance and long service life. An air-cooled chiller made by TopChiller consists of a scroll compressor, air-cooled type condenser, built-in water pump, and water tank to make a complete compressed refrigeration and water cooling system. Chilled water is used to cool and dehumidify air in mid- to large-size commercial, industrial, and institutional facilities. Water chillers can be water-cooled, air-cooled, or evaporatively cooled. Water-cooled chillers incorporate the use of cooling towers which improve the chillers’ thermodynamic effectiveness as compared to air-cooled chillers. This is due to heat rejection at or near the air’s wet-bulb temperature rather than the higher, sometimes much higher, dry-bulb temperature. Evaporatively cooled chillers offer higher efficiencies than air-cooled chillers but lower than water-cooled chillers.
As for a cooling tower, this system is designed to remove heat from any water that’s discharged from the condenser unit. Even though these systems provide similar results, the slight differences between the two are why chillers and cooling towers are typically used for different applications. Acquired by KIG in May 2015 was this nice 2005 Trane Air Cooled Chiller. The unit was in storage in the Southeast USA for a few years, as it was purchased by our client, but their business situation changed so they never used it. We paid a local chiller specialist to inspect megger compressors, confirm operation of the low ambient option, power up controls, and do overall inspection. This chiller has the original 4 scroll compressors in it (that’s good, no mis-application problems causing compressor swap-out), and low ambient option for year round operation in colder climates.
The refrigerant then passes through an expansion valve, where it rapidly cools and goes through the evaporator, where it cools the chilled water. The chiller controller manages the switching between operating modes according to the ambient temperature and humidity, thus realizing the most energy efficient cooling regime. Water-cooled chillers have greater complexity due to the connection to a cooling tower system. Water-cooled chillers typically reside indoors in an environment protected from the elements. Water-cooled chillers typically represent the only option for larger installations. The additional cooling tower system will require additional installation expense and maintenance as compared to air-cooled chillers. The refrigerant then flows to a compressor, which performs multiple functions. First, it removes refrigerant from the evaporator and ensures that the pressure in the evaporator remains low enough to absorb heat at the correct rate. Second, it raises the pressure in outgoing refrigerant vapor to ensure that its temperature remains high enough to release heat when it reaches the condenser.
Rack-Mount water chillers has 2 temperature control modes as constant temperature and intelligent temperature control mode. Kaltra advanced chilled water plant with inverter-driven chillers offer a 30% reduction in energy consumption and environment-safe cooling with R1234ze gas.

Arrived at KIG in June 2015 was this super nice 2008 Carrier Aquasnap Air Cooled Chiller loaded with options. Equally fine for comfort cooling or other manufacturing operations. It is outdoor rated, has dual compressor, and minimum load control for efficient operation. This chiller was run and tested at our Massachusetts facility extensively.
The cooling process begins when water enters the evaporator from the primary return where heat is transferred from the water to the refrigerant. With over 50 years of collective experience in the refrigeration industry, G&D’s Chiller expertise goes far beyond the design and implementation of cutting edge glycol chilling systems. Many of the leading breweries, wineries, distilleries, agriculture & food, dairy, and industrial manufacturers here in the USA and around the world, turn to us for innovative Glycol Chillers. Cost – Water-cooled chillers tend to be more expensive upfront because they take more time to install and require extra parts, such as cooling towers and additional fluid plumbing. However, many companies find the energy savings and extended lifespan worth the initial investment. Energy efficiency – The lower refrigerant condensing temperature and pressure help water-cooled chillers operate efficiently.

Request a quote from our team today to learn how we can help with your process cooling needs. Some users may prefer these chillers because of the smaller size they occupy as compared to air-cooled chillers. These chillers also feature higher efficiency and last longer than the mentioned alternative. Those who would like the equipment to be placed indoors may find the water-cooled machine desirable. Consume approximately 10% more power than a water-cooled unit due to wet surfaces transferring heat better than dry surfaces. Aqua Series chillers make their noise in the marketplace, not the workplace. The AquaSnap chiller’s low-sound AeroAcoustic® fan produces up to half the sound level of the propeller fan.
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.

For a tower sited in an awkward position, for instance a hole, it is important to consult Araner for advice from the tower selection stage. Installation of air-cooled systems should be in such a way that no obstruction occurs to airflow on both the air discharge and air intake sides. Avoid placing the condenser near a wall or ceiling to prevent air obstruction. Chiller claims are no walk in the park – several components can malfunction and cause the entire system to fail, and the source may not always be clear. Our trained technicians will document the damages and our experts will put together a comprehensive report outlining damages, cause of loss, and costs involved with repair or replacement. Chillers use metal tubes to transfer water between the chiller and the climate-controlled space.
We provided this new to one of our repeat customers, who wanted to quickly upgrade to a 10 ton outdoor rated unit; so we have this back in trade. This is a nice, basic indoor chiller, with a process temp range of 42°F to 72°F. Arrived at KIG in October 2020 is a perfect General Air Products 14 ton Air Cooled Chiller. Our 30-ton air-cooled screw chiller is just what you need for anodizing applications. Even if you find your current cooling method is working, we are confident you will find using our industrial screw chillers for your cooling needs will be far more convenient and efficient. Plating — either electroplating or electroless plating — is becoming a major industry as more industries are looking for metal finishing experts to complete their products. Plating metal requires a tremendous amount of heat, which you then must remove. You need strong industrial screw chillers for that kind of job, which is just what we provide.
Air cooled chillers are very common, especially in small to medium size commercial and office type buildings. They are usually located externally, either up on the roof or at ground level. This is because Air Cooled Chillers do not use cooling towers, instead they dump their heat into the ambient air and therefore need access to a lot of fresh air, in order to reject the unwanted heat from the building. Scroll to the bottom to watch the tutorial video on this subject. Traditionally, Air-Cooled Chillers operate in a closed loop cooling application where all of the water pumped from the chiller returns to the main unit under the pressure generated by the pump. Air-Cooled chillers absorb heat from process water, and the heat is then transferred to the air around the chiller unit. This type of chiller system is generally used in applications where the additional heat it discharges is not a factor. In fact, it’s often practical to use the excess heat to warm a plant during the winter, thus providing additional cost savings.
