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.
This unit is 460 volt, and has two scroll compressors, a brazed plate heat exchanger, Carrier’s quiet fans, and Comfort-Link Controls. This unit is outdoor weather rated, although we have seen users run them indoors also. This chiller was run and tested at our Massachusetts facility, where we ship about 100 chillers per year from. 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. Offered by KIG in October 2019 was this pristine 2012 Thermal Care NQ series Air Cooled Chiller. It is 460 volt 3 phase power, has dual scroll compressors, the newer R410a refrigerant, and 20°F to 80°F fluid/glycol temperature range. This is an indoor chiller, yet the exhaust can be ducted outside if you choose, as it was at its prior location. This unit is made by Thermal Care and the case was re-branded through IMS . We have provided dozens of these Thermal Care units over the years, and they are well-built true workhorses. Arrived at KIG in April 2020 was this nice pre-owned Koolant Koolers / Dimplex Thermal 5 ton Air Cooled Chiller.

Air cooled chillers are a common type of liquid chiller because they are simple to install, easy to maintain, and typically less expensive than water-cooled chillers and evaporation-cooled chillers. Air coolers eliminate the need for a cooling tower or condenser water pump, so they often take up less space than other types as well. However, air cooled chillers require more power to operate, typically consuming approximately 10% more power than a water cooled unit. This is because of the need for higher condensing temperatures (120° F to 140° F), combined with the fact that dry surfaces transfer heat less efficiently than wet surfaces. Since the heat from the process liquid is transferred into the air, air cooled chillers can be used strategically in systems in which the additional heat they discharge is beneficial. For instance, the hot air produced by air cooled chillers can be directed to help heat facilities during the winter. Air cooled chillers can be used for applications including troughs, tanks, nozzles, mixers, rolls, air coils and radiators, lasers, molds and dies, among others. This is a pristine Central Type Chiller System ideal for your plastics or other manufacturing operation. Arrived at KIG in December 2015 was this super nice Carrier Aquasnap 35 ton Air Cooled Chiller. Unit was completely run and tested at our 13,000 square foot facility prior to shipping, and offered with money back guarantee.
The Cygnus Tech is also highly appealing to anyone focusing on air-cooled chiller efficiency, with environmentally friendly refrigerant R410A, and high seasonal efficiency levels. Like with water-cooled chillers, the process begins with the primary return bringing warm water to the chiller. Heat is transferred in the evaporator to the refrigerant, and the water runs through the primary supply to the cooled space. The refrigerant moves through the compressor to raise the pressure and temperature, and then it reaches the condenser. Here, fans circulate outside air through the condenser, which absorbs heat from the refrigerant before expelling this heat to the ambient air. The refrigerant then goes through the expansion valve and returns to the evaporator. Arrived at KIG in February 2016 was this never used, never installed , new 2014 Koolant Koolers / Dimplex Thermal 40 ton 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. This is an outdoor weather rated unit, although we see users install indoors too. This unit requires you have your own process pump/reservoir arrangement. If the unit is to run year round in a cold weather climate, a low ambient option will need to added/quoted. Arrived at KIG in March 2016 was this excellent condition 2001 Thermal Care 15 ton Air Cooled Chiller.
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.
Arrived in March 2020 was this nice 2010 Econochill 5 ton Air Cooled Chiller. This chiller has been refurbished, cleaned, and tested at our shop prior to shipping. It is 230 volt, 3 phase power, scroll compressor, R410a refrigerant, and 45°F+ fluid/glycol “standard” temperature range. Consult with us if 25°F glycol temps needed or if it’s for a brewery. It is outdoor rated and has an insulated tank and a 1.5 hp process pump. We have provided dozens of these units to customers over the years, and they are well-built true workhorses. For medium to large chillers this should range from 3.5 to 7.0, with higher values meaning higher efficiency. In the US, chiller efficiency is often specified in kilowatts per refrigeration ton (kW/RT).
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.
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 and water-cooled chillers both perform under similar principles to transfer heat and create a cooler environment. However, air-cooled chillers can be installed outside, which means there is no need for physical space for air-cooled chillers. Air-cooled chillers can be also found in the beverage processing industry. The pasta and food need to be cooled down rapidly when processing at high temperatures. In the laser cutting industry, the air-cooled chiller is mainly used in laser machines, such as laser marking and engraving machines, laser welding machines, laser printers, laser cutting machines. This process can increase the density and smoothness of the products. As a result, the production efficiency of molding machines is significantly upgraded by air-cooled chillers. Air-cooled chillers can greatly improve the surface of plastic products, eliminate surface marks, and relieve the internal stress of plastic products. The outer of this water tank also should be covered with heavy insulation.
Small building with cooling loads under 200 tons or 700 kW will typically use scroll compressors or Turbocor compressors and are typically of air cooled design. Again we’ll look at why just shortly, they might also use a different system such as VRF units but this depends on the size of the building and the cooling load.
