These are ideal for customers with mold related heat issues and water quality issues. In the evaporator, chilled water is created when unwanted heat is drawn into the refrigerant before it is fed into the condenser. The differences between air conditioning and chillers can be subtle at the cooling process level, but very different in applied usage. Chiller operational efficiency will greatly impact your building operating costs. Ongoing routine maintenance represents the minimum from the perspective of facility management. Predictive maintenance and optimization of the chiller system requires real-time operational data. Artificial Intelligence continues to advance in everyday practical applications. Machinery such as chiller systems will benefit from AI algorithms that can detect potential failures before they occur. Predictive maintenance leverages the collection and analysis of chiller system operational data to determine when maintenance actions should be taken prior to catastrophic failure.
It is widely used in electronics, electroplating, food, machinery, chemical, laser, card making, medical and other industries. Because the source of heat exchange is gas and it is equipped with a special electric fan, it is called “air cooling”. S&A Teyu CW-3000 series thermolysis type recirculating industrial water chillers are able to cool CO2 laser tube,CNC spindles,welding equipment, lab equipment or low power equipment. Water-cooled chillers are installed in the building, therefore protected by the elements and giving them a longer lifespan. At times, this is the only option for larger installations and can provide better energy efficiency. Low-pressure water-coolers offer a significant reduction in emissions over the system’s lifetime . Let’s be real, money one of the most important factors when looking at what chiller to install. Initially, air-cooled chillers are lower than water-cooled chillers.
Has Micro Channel Coils, Coil Guards, and Low Ambient VFD option for year round cooling even in colder climates. Arrived at KIG in April 2016 was this nice Zarsky / Cold Shot 20 ton Air Cooled Chiller. 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. It has a 1 hp pump and is a “tankless” design, intended to draw from your tank/reservoir, through the heat exchanger, then back out to your process or holding tank. This is an indoor chiller, with fluid setpoint range of 50°F to 90°F.
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.
See our run off videos below of similar unit already shipped to customer. Arrived at KIG in March 2016 was this never used, never installed, 2013 Koolant Koolers DVI-7500-M 7.5 ton “Drop-In” Air Cooled Chiller. This 460 Volt INDOOR chiller is designed to be lowered into your existing process tank for your process. There are two coil heat exchangers to be submerged in your oil or water-soluble fluid. Unit features a 7.5 hp scroll compressor, uses R407c refrigerant, and some nice Carel controls. Arrived at KIG in November 2018 was this 2014 Cold Shot Air Cooled Chiller. We have refurbished, tested, and supplied dozens of this brand to various industries over the years.
Also based on cooling methods, chillers can be divided into air cooled chillers and water cooled chillers based on the cooling method. Each air cooled chiller manufactured from TopChiller has a built-in water tank and water pump, some of the charged refrigerant R407c, R410a and R134a are also available for high ambient temperature. Compa-Chill Central Air Cooled Whaley Chillers are used in industrial and commercial applications from central chilling of processes to HVAC. COMPA-CHILL has become the number one chilling equipment of choice, which incorporates new high efficiency Scroll compressors and stainless steel plate evaporators. Central chillers are designed to cool multiple processes with one chiller system. The multi-circuit design is used on critical process loads that absolutely cannot be down. WPI will provide complete water system design and plant process survey to determine cooling loads.
The difference between air cooled and water cooled chillers is that air chillers use ambient air as the condensing source and a fan that moves the air over the coil. Water chillers on the other hand use water as the condensing source and a pump that circulates water through the condenser out to the cooling tower that releases it into the atmosphere. This GCI Icewagon 13 ton Air Cooled Chiller arrived into KIG’s shop in May 2014. We have cleaned and painted the unit, and done any repairs and checks as needed. It has been run and tested and was offered with a money back guarantee. It is 460 Volt, has a Danfoss/Maneurop 13 hp sealed reciprocating compressor which we have had great luck with on chillers in the past. Chiller has hot gas bypass option so as to keep compressor running a bit longer when there is a lower load on the system, which reduces the amounts of starts and stops on the system. This unit does not have an on-board reservoir tank, but could easily integrate with your storage/buffer tank as the inlet to the chiller goes right to the suction side of pump.
Arrived at KIG in January 2016 were these three immaculate Donaldson 10 ton Air Cooled Chillers. The European designed units are wonderfully engineered, and can run in low ambient conditions as well as high ambient conditions. They are also suitable for Glycol fluid chilling in the 28°F range, but equally as fine for your industrial cooling application too. Units are 460 volt 3 phase power, and were run and tested thoroughly in our shop prior to shipping. Arrived at KIG in April 2017 were these 2 never used surplus Dual Compressor 6 ton Riedel Air Cooled Chillers. Unit is wonderfully engineered, and although not intended to be out in the elements and precipitation, it has enhanced hi/low ambient, so it can run in -4°F to 106°F ambient conditions.
The first way to categorise a chiller is by defining whether it is a vapor compression or vapor absorption type chiller. Arrived at KIG in March 2016 was this nice Trane RTAA 125 Air Cooled Chiller with Dual Rotary Screw Compressors and R22 refrigerant. These are workhorses in the industry if you are familiar with chillers. This unit underwent some cosmetic sheet metal repair due to some slight mishandling during shipping. The unit was completely checked out by a licensed HVAC tech prior to shipping. System uses one 30 hp Scorll compressor, and the newer R407C refrigerant . Each unit was RUN and TESTED thoroughly in our Massachusetts shop prior to shipping. Because this is a split/remote condenser “2 piece” chiller system, this offer was for an untested system as-is. In its present form, the condenser does not have the “low ambient” winter package with fan switching/VFD controls to allow to run in less than 40°F ambient conditions. If you are in the cold winter environment, consult with us on cost to add this, or you can have your local contractor install also.
Unit also has the protective louvers over the coil fins, and the coils are therefore perfect as can be expected. Available from KIG starting in October 2020 is this new condition, never used, pre-owned 2019 Carrier Aquasnap 80 ton air cooled chiller, LOADED with options. Photo #1 was an application of two Trane air cooled chillers located outside of a hospital – Disturbing tonal noise was being produced to the adjacent neighbors 2 blocks away. Unger performed field sound measurements with a 1/3rd octave band sound level meter both near/far field along with property line sound measurements. Fluid Chillers, Inc. is a US based manufacturer of industrial chillers, medical chillers, food chillers, oil chillers, and all process fluid cooling systems from 1/3 tons to 500 ton capacity. Air cooled chillers use the refrigeration cycle to produce chilled fluid, typically water or a mix of water and glycol.
Since the wet-bulb temperature is always lower than the dry-bulb temperature, the refrigerant condensing temperature in a water-cooled chiller can often operate significantly lower than an air-cooled chiller. With 20 years of experience in air cooled screw chiller manufacturing, TopChiller is willing to provide all technical support to clients worldwide. Even if the customized air cooled screw chiller based on your specific requirements, we also have all ready screw chiller spare parts. As there are many industries and each industry may require air cooled screw chillers of specific sizes and cooling capacities. For each air cooled screw chiller purchased from TopChiller®, its quality must be carefully checked before shipment to ensure the client will receive a satisfying chiller. 24-months warranty time – for air cooled screw chiller is warranted to be free from defects in material and workmanship.
However, the annual comprehensive cost of air-cooled screw chiller is basically the same as that of water-cooled units. As mentioned above, when a chiller comes with a screw compressor, it will be named a screw chiller. Water-cooled screw chillers use water consumption whereas air-cooled screw chillers need air ventilation. They work under similar principles to finish the heat transfer but they use different components to cool the condensers. In the meantime, the water temperature cools down when the heat is extracted by the refrigerant. The shell and tube evaporator is designed to collect the waste heat from the outside and transfer it into the refrigerant.
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.
