If you require unlimited cooling water for your industrial application, a natural draft cooling tower may be the right choice for you. Since mechanical fans don’t need to be used in this type of cooling tower, the expenses for operating the cooling tower are lower than what’s necessary for a mechanical draft cooling tower. If you require a system that will effectively cool your food processing unit or power plant, the two main types of systems that can be used for numerous cooling purposes include a chiller and a cooling tower. While both of these systems are designed to remove any heat from a liquid before it’s used as a coolant, there are distinct differences between the two systems that you should be fully aware of. Arrived at KIG in October 2014 was this immaculate and well maintained Trane CGAM series 90 ton Air Cooled Chiller. Unit has less than 9500 total run hours, and see the low hours per compressor below.
Chillers provide a continuous flow of coolant to the cold side of a process water system at a desired temperature of about 50°F (10°C). The coolant is then pumped through the process, extracting heat out of one area of a facility (e.g., machinery, process equipment, etc.) as it flows back to the return side of the process water system. Chillers have become an essential HVAC component of a wide variety of commercial facilities, including hotels, restaurants, hospitals, sporting arenas, industrial and manufacturing plants, etc. The industry has long recognized that chiller systems represent the single largest consumer of electrical usage in most facilities. They can easily consume more than 50% of the total electrical usage during seasonal periods. According to the US Department of Energy , chillers can combine to use approximately 20% of the total electric power generated in North America. Moreover, the DOE estimates that chillers can expend up to 30% in additional energy usage due to various operational inefficiencies.
They use a motorized blower to force air across a grid of refrigerant lines. Unless they are specially designed for high-ambient conditions, air-cooled condensers require ambient temperatures of 95°F (35°C) or below to operate effectively. As described, two different cooling mediums can facilitate the transfer of the latent heat given up as the refrigerant changes from vapor to liquid. Thus, chillers can use two different types of condensers, air-cooled and water-cooled. Standard features include state-of-the-art weather protection for V-shaped coils, enhancing the high-efficiency operating life of the total chiller unit. Accurately designed for trouble-free and sustained operation across the entire chiller load range.
This ~40 ton unit is outdoor rated, and has 3 Danfoss Scroll Compressors, and an insulated stainless tank. In depth video on one of our SSCD air cooled screw chillers featuring our President, Tim Baker. eNoise Control was retained by the Architect and City to perform a noise survey and recommended noise abatement strategies. We took field sound measurements with a 1/3rd octave band sound level meter both near/far field along with property line sound measurements. A chiller is simply a facilitator of heat transfer between the inside and the outside of a building, and the chilled water system can have many different configurations. Air-cooled chillers and water-cooled chillers are the most commonly used types of chillers. Chilled water systems are typically used for cooling medium and large buildings. While the upfront cost of a water chilled system can be a lot, the greater energy efficiency and lower maintenance costs usually make up for it. The condenser water flows through the chiller and picks up heat. The cooling tower is almost always located outside of the building and removes heat from the condenser water by evaporating some of the condenser water into the atmosphere.
The less common open loop industrial chillers control the temperature of a liquid in an open tank or sump by constantly recirculating it. The liquid is drawn from the tank, pumped through the chiller and back to the tank. In industrial water chillers is the use of water cooling instead of air cooling. In this case the condenser does not cool the hot refrigerant with ambient air, but uses water that is cooled by a cooling tower. Additionally, the absence of fans allows for significantly reduced noise levels. Our air cooled chillers are designed to be ‘plug and play’ for ease of operation. The plug and play design closed loop systems are designed to minimize maintenance costs lowering the lifetime cost of the unit. The majority of regular maintenance that needs to be performed on an air cooled chiller is the cleaning of the condenser, maintaining water PH level of 7, and ensuring proper air flow around the unit is maintained. Arrived at KIG in October 2019 was this nice 2014 “20 ton” Aqua Products Glycol Chiller with remote buffer tank module. We took this unit in trade-in, as our local brewery customer has experienced incredible growth and has installed a new York/Johnson Controls 200 ton unit in its place.
While this does fix the problem it is a temporary solution as the chiller must work harder for the same effect. Motivair’s Heat Dissipation Unit™ is an active heat exchanger that converts liquid-cooled computer systems to air-cooled by rejecting heat to the server room.

A common step of many types of beverage production is cooking, mixing, and pasteurizing. Whether its soda, beer, milk, or other drinks the beverage industry relies on chillers to remove heat produced by these processes.
Arrived at KIG in January 2018 was this NEVER USED new condition Advantage/Temptek 2 ton Brewery Chiller. This is an indoor chiller, specifically built for a brewery with an upgraded 2 hp process glycol pump, 25°F glycol temp range, and special piping configuration for your glycol supply/return loop to multiple tanks. Unit can be used for other cooling applications at higher temps if needed also. Air cooled chillers use air to remove heat by using fans to force air across the exposed tubes of the condenser. While air chillers require more energy than water-cooled chillers, they can be a great option when it comes to stationary cooling. Air chillers are easy to instal and typically can be installed outside a building . Compared to water chillers, air chillers are more prone to blockages and recirculation issues.
Absorption and adsorption chillers require a heat source to function. Starting at thecompressor; the refrigerant is compressed and sent out of the compressor as a high temperature, high pressure, superheated gas. The condenser changes the refrigerant from a high temperature gas to a warm temperature liquid. The TXV meters the proper amount of refrigerant into the evaporator. The TXV takes the high pressure liquid and changes it to a low pressure cold saturated gas. This saturated gas enters theevaporatorwhere it is changed to a cool dry gas . The cool “dry” gas then re-enters the compressor to be pressurized again. The “hot gas by pass” orunloader assemblyis used to stabilize the cooling output of the refrigeration system by allowing hot gas to warm up the cool evaporator. This causes a reduction in the cooling efficiency and a stabilizing of the supply chilled water temperature. There are a few other unloader concepts that are used in refrigeration systems, but ideally accomplish the same outcome.
Air-cooled machines are directly cooled by ambient air being mechanically circulated directly through the machine’s condenser coil to expel heat to the atmosphere. Evaporative cooled machines are similar, except they implement a mist of water over the condenser coil to aid in condenser cooling, making the machine more efficient than a traditional air-cooled machine. No remote cooling tower is typically required with either of these types of packaged air-cooled or evaporatively cooled chillers. Water cooled and air cooled chillers work in a rather similar manner. They both have an evaporator, compressor, condenser and an expansion valve. The main difference is that one uses air to fuel condenser cooling and the other uses water. These benefits aside, the fantastic customisation benefits on offer open customers to options such as low water temperature configurations to -10 degrees, water accumulation tanks, and total heat recovery. If you’re seeking coolers that last, then there’s certainly no need to look further than the Aries Tech 2. A chiller is a relatively basic system wherein heat is removed directly from the coolant before it’s transferred over to the surrounding air, which is essential for the cooling process.
This unit is 230 volt 3 phase, has an insulated stainless tank, is outdoor rated , and has an upgraded 3.0 hp process pump.

MTA’s cooling solutions, developed specifically for industrial users, perfectly answer industry’s need for precise temperature control and absolute reliability, 24 hours a day, 365 days a year. The cost of not implementing the optimised solution far exceed the cost of an optimised MTA industrial cooling solution. Heat transfer has a large effect on chiller systems and remains fundamental to producing efficient chiller operation. Routine maintenance should inspect condenser coils for clogging and free air passage. A typical air-cooled chiller can feature propeller fans or mechanical refrigeration cycles to draw ambient air over a finned coil to condense the refrigerant. The condensation of the refrigerant vapor in the air-cooled condenser enables the transfer of heat to the atmosphere.
Chiller costs consume a substantial part of your building’s utility bills. What measures should one take to obtain energy savings through maximal efficiency of the chiller system? The all-inclusive nature of air-cooled chillers reduces maintenance costs. Their relative simplicity coupled with reduced space requirements produces great advantages in many types of installations. In general, a chiller facilitates the transfer of heat from an internal environment to an external environment. This heat-transfer device relies on the physical state of a refrigerant as it circulates through the chiller system. Certainly, chillers can function as the heart of any central HVAC system.
