The compressor is then tasked with pumping the refrigerant vapor to the condenser, which increases temperature and pressure. The refrigerant condenses when it’s in the condenser tubes, releasing its internal heat to the air or cooling water. The high-pressure liquid then moves through the expansion device and into the evaporator; in the process the refrigerant pressure is reduced along with the temperature. To complete the continuous cycle, the refrigerant flows back over the chilled water coils and absorbs more heat. An air-cooled chiller works by absorbing the heat from processed water.
Utilizing micro-channel condenser coils, the NYB has a 40% lower charge of zero ODP R410A refrigerant than traditional-coil chillers. A desuperheater option allows for otherwise-rejected heat energy to be recycled for use in domestic water systems. Acquired by KIG in March 2015 was this nice 50 ton Koolant Koolers / Dimplex Thermal 50 ton Air Cooled Chiller. It was stored at a California riggers yard, we had it inspected and controls powered up, and it had 0 COMPRESSOR HOURS, and 0.16 PUMP HOURS! We learned that the prior owner had it installed at the same time a cooling tower and pump tank which they discovered achieved all their required cooling. In addition to being a desirable size, it also has an onboard 15 hp process pump and onboard reservoir tank.
When making food for human consumption, keeping your food products free from bacteria or other contaminants that could poison those who consume it is the number-one priority. A few people getting sick could ruin a food processing business, let alone if something worse happens. One of the best ways to prevent food from going bad is to control the temperature, as most bacteria cannot survive in extremely low temperatures. A world leading company in wireless technologies opt for three 1,400-ton chillers powered by 21 Danfoss Turbocor™ compressors to improve efficiency and lower costs at data center.
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 March 2016 was this 2014 Koolant Koolers 3 Ton “AVI Series” Air Cooled Chiller. It features a cleanable heat exchanger where the plates can be disassembled. It is ideal for dirty fluid or problem fluid, yet fine for clean water/fluid of course too.
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.
About 7500 hrs total run time, and 3500 hr or less on each of the 4 compressors. Arrived at KIG in October 2017 was this amazingly clean 2012 Trane Air Cooled 40 ton CGAM Chiller. Unit is 208/230 volt, 3 phase, has low ambient option for colder climates , and with its electronic expansion valves this unit can run glycol temps in the 25°F range.
If the flow is too high, it can cause damage to the equipment. Ideally, the flow rate should be kept between 3 to 12 feet per second. The first step to keep ensuring your chiller is working optimally is to establish a historical record of trends in equipment operation. A historical record will allow you to see operational conditions such as temperatures, pressures, fluid levels, and flow rates. It will also help you keep track of anomalies that may lead to the need for parts repairs or replacements. Renting great equipment will be the easiest part of your job because we promise Availability, Reliability, and Ease — in terms of both our people and our products.
These acknowledged inefficiencies cost companies and building facilities billions of dollars annually. Cooling Power offers air cooled chillers to meet a wide variety of needs and demands.

The refrigerant is the only fluid which moves around each of the components of the chiller. It changes its pressure, temperature, enthalpy and entroy as it moves around the machine and transports the unwanted heat away from the evaporator chilled water.
Their relative simplicity coupled with reduced space requirements produces great advantages in many types of installations. The refrigerant then enters the evaporator and will pass through a series of horizontal tubes which are surrounded by the “chilled water” and these will flow in the opposing, counter flow to each other. By the time the refrigerant leaves the evaporator, it will have picked up the unwanted heat from the return chilled water and will leave as a low pressure, low temperature saturated vapour. The chilled water will have given its thermal energy up to the refrigerant and will leave around 6°C (42.8°F).
Here are the key differences you need to know as you look at AC installation in Loganville, GA. Water condensing, air condensing and split systems all available in a wide range of cooling capacities. BluChill is your source for quality industrial chillers, competitive prices and fast, friendly service.
This was a nice 2013 Trane 20 ton Series CGAM chiller that was shipped from northern California. Chiller was used very little due to wrong size being ordered. Because this is a split/remote condenser “2 piece” chiller system, this offer was for an untested system as-is. Arrived at KIG in January 2020 was a perfect General Air Products 19 ton Air Cooled Chiller. It is outdoor rated, and has broad fluid setpoint range and is capable of lower glycol temps. reservoir underneath, and the on board process pump integrated with the Carrier Comfort Link Controls.
Chillers use metal tubes to transfer water between the chiller and the climate-controlled space. The simple presence of oxygen in water can cause corrosion, but if the water and pipes are treated properly, this can significantly reduce the risk. However, if the water treatment is inadequate, sediment, minerals, and bacteria can enter the system. If there is a buildup of sediment or bacteria that causes oxygenation levels to differentiate, the metals can begin to corrode. In addition, any point where two different metals are used can be at risk for corrosion due to their different electrochemical properties. No matter how the corrosion occurs, it can cause leaks that will damage the chiller, reduce its efficiency, and possibly damage the area surrounding the chiller.
