If you plan on running this unit for year round process cooling, AND you are in a cold climate, a low ambient VFD drive option for the condenser fans will be required. Acquired by KIG in March 2015 was this nice 15 ton Carrier Aquasnap Air Cooled Chiller. This unit ran at a military base and was maintained regularly by a mechanical contractor we deal with. We refurbish/test/ship about 10 to 20 Aquasnap chillers annually from our Clinton MA facility, and this unit was run and tested prior to shipment, and sold with a money back guarantee of functionality. The unit has a single 15 hp scroll compressor, comfort link controls, internal flow switch, and hot gas bypass option for minimum capacity control if your load is not a full 15 ton.
Although this is currently on Budzar’s site, it references older refrigerant and some other differences. This unit arrived in early October 2014, and went through refurbishment at KIG. Each unit was RUN and TESTED thoroughly in our Massachusetts shop prior to shipping. Unit was run and tested at KIG facility in Clinton MA by our own chiller technician. This unit arrived at KIG’s shop first week of July 2014, and went through testing and refurbishment.
Free-cooling and combination chiller-heat pump units are excluded. Water-cooled electric chillers are covered by FEMP efficiency requirements under a separate product category. The air cooled chiller system assures the stable chilled water supply.
As a consulting engineer, knowing when to design an air-cooled chilled water plant or a water-cooled chilled water plant can be challenging. Client goals and site constraints will often serve as reliable guides for the best choices. When thinking of long-term aspects of a building, an owner will see higher cost savings in regard to efficiency with a water-cooled chiller plant. At a quick glance or base comparison of size and cost, the air-cooled chiller plant is more cost-effective. The average cost of an air-cooled chiller plant is roughly $1,300/ton while the water-cooled chiller plant is approximately $1,700/ton. For the same 200-ton chiller plant, the cost of the air-cooled chiller plant would be roughly $260,000 compared to the $340,000 to $400,000 water-cooled chiller plant.
Water cooled chillers pump water through a sealed condenser and disperse it through a cooling tower. Air cooled chillers use fans to force cool air across the condenser. These chillers can be applied to any industrial process that requires year-round cooling, including Hydraulics, plastic molding, chemical, food & pharmaceutical production.
The main difference is that one uses air to fuel condenser cooling and the other uses water. In this article we will be looking at how air cooled chillers work. 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. Scroll to the bottom to watch the tutorial video on this subject. The growing industrialization in several countries across the world has led to an increase in the number of industrial manufacturing units.
Arrived at KIG in August 2017 was this nice 2005 Temptek Air Cooled Chiller. This is an indoor chiller, and can be used for higher temp manufacturing applications as well. This unit is 208/230 volt SINGLE phase, has a reservoir tank, a 1/2 hp positive displacement pump.
Calculated based on the highest efficiency model identified in publicly provided manufacturer data as of June 2020. Note that more efficient models may be introduced to the market after FEMP’s acquisition guidance is posted. Federal purchases must meet or exceed the minimum efficiency requirements in Table 1. Note that efficiency requirements differ by full- and part-load optimized applications. If your process requires customization, here are options that may be added to manufacture a chiller specific to your needs.
Because an industrial chiller works on a continuous cycle, this low-pressure liquid is then transferred back to the evaporator where the whole cycle will repeat itself. Delta T Systems is introducing a completely new single and dual zone temperature control heater/chiller combo package. GCI’s versatile family of DS Series Icewagon™ chillers is engineered for general purpose applications, where performance, cost, and operating flexibility are key requirements. Both air and water condensing models are available, and the series comes with compressors sized from 1 to 12 hp to meet a broad range of industrial cooling needs. Rugged yet compact, the DS Series incorporates many of the features found on larger, more expensive chillers.
Our air-cooled screw chiller can save you dramatically by reducing product loss. The new Alsik hotel in Southern Denmark sets a higher standard in energy-efficiency and is built to reach 76% CO₂-neutrality. A main contributor is the 900-kW chillers by Clint (a company of G.I. Industrial Holding) which features award-winning Danfoss Turbocor oil-free compressors. NRV and NRVH can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plants with fluorinated refrigerants. NRV and NRVH can be supplied with flare and solder connections. They are also available with oversize solder connections providing flexibility in the use of check valves.
To get rid of the heat that was absorbed, the refrigerant is pushed into a tube called the evaporator, which allows the fluid to release the absorbed heat so it can be reused. On average, an air-cooled chiller’s lifespan is anywhere from 15 years to 20 years. Where your chiller is located and the conditions it’s under can also affect its life expectancy.
These Air cooled Screw chillers available in various models and designs. which gives the ideal decision to the purchasers to settle on the most appropriate Air Cooled Chillers for their individual expert set up. They are highly sought after and are beneficial for any system. The flexible design of Jetson chillers allows applications in both process and comfort cooling applications.
Once the water in the air handler system is used, it becomes warm and is sent back to the chiller. Heat is transferred away from the water using the chiller’s evaporator. Liquid refrigerant evaporates as it moves over the evaporator tube, creating a low-pressure gas. Next, the evaporated refrigerant travels to the compressor where the low-pressure gas is compressed into a high-pressure gas. While in the condenser, heat is removed from the chiller by being blown outside through fans on the side of the condenser. Because the heat is blown outside of the chiller, it is ideal to place the chiller outdoors or in a large indoor location that will not be affected by the excess heat.
