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.
With colder temps, the refrigeration compressors unload until they are no longer required, and the full cooling capacity is provided by the condenser-fan alone. An air cooled chiller is a machine that removes heat from a liquid via a vapor-compression cycle. Air cooled chillers are directly cooled by ambient air being mechanically circulated directly through the machine’s condenser coil to expel heat to the atmosphere.
Equally fine for comfort cooling or other manufacturing operations. It is outdoor rated, has dual compressor, and minimum load control for efficient operation. This chiller was run and tested at our Massachusetts facility extensively. Arrived at KIG in April 2016 was this nice Zarsky / Cold Shot 20 ton Air Cooled Chiller.
Our DS Series of portable chillers has become the industry standard because of its exceptional value, not to mention our staunch commitment to customer service. Arrived at KIG in September 2015 was this outdoor 80 ton Air Cooled Chiller, originally sold to a manufacturing company in 2001 in Illinois, and they never needed to use it after they installed it. This is an amazing deal for a manufacturer who needs an outdoor rated chiller and has the need and can appreciate the onboard pumping/tank package. Unit was disconnected from power and removed from facility in August 2015.
Experience reliable and consistent temperature control as well as unmatched customer service when you choose Thermo Fisher Scientific. For illustrative purposes, a 200-ton air-cooled chiller plant will be compared to a 200-ton water-cooled chiller plant. A primary-secondary pumping arrangement consists of a primary loop in which the water is pumped through the chiller constantly or variably to produce the desired chilled water temperature. Note that at a general level a water cooled chiller has a greater cooling capacity that’s given by the heat transfer rate of the water and therefore is more advisable in large buildings. Air cooled chillers house all of these components in a single space saving cabinet that is easily incorporated into any operation.
It also offers an exclusive insight into various details such as revenues, market share, strategies, growth rate, product & their pricing by region/country for all major companies. Variable Speed chillers can reduce electrical consumption by up to 50% over fixed speed units. Standard single controller and program capable of controlling two processes at different temperatures and pumping capacities. Use our selector tool to find the perfect heating and cooling products for your comfort needs. We offer air-cooled and water-cooled chiller plants with 24/7 emergency delivery and installation available.
In this case, we will consider the chiller and pumps for an air-cooled chiller plant and the chiller, cooling tower and pumps for a water-cooled chiller plant. An average air-cooled chiller plant has an efficiency of roughly 1.5 kW/ton, while the efficiency of a water-cooled chiller plant is approximately 0.85 kW/ton. Obviously, a water-cooled chiller plant is more efficient, but that is not the only factor to consider. This same concept applies to condenser water and hot water systems. The use of VFDs also reduces the energy consumption of the pumps greatly. For example, a pump that operates at constant speed will use the same power consumption of the pump all the time, whether the building demand is at 100% capacity or at 50% capacity.
Our PCR chillers are designed and built to provide reliable service 24 hours a day, seven days a week. When a standard chiller doesn’t quite fit, we will gladly build a custom unit to meet your exact requirements. Please contact us for a pleasant experience with your next chiller.
Given the annual temperature range in this area, the savings were readily apparent. Whenever the outside air temperature falls below 70 °F, the return chilled glycol solution is automatically diverted through the integrated Free Cooling coils of the chiller. These coils are located across the inlet-air side of the air-cooled condensers and use the condenser fans to pre-cool the return glycol. As the ambient temperature falls, the pre-cooling increases – until at approximately 20 °F below the supply glycol temperature – the chiller operates entirely without compressors. Everyone wants their energy systems to be energy efficient, but you should know that chiller efficiency is calculated differently between the different types.

From process to structural cooling, our chiller rental department offers you many options for any of your temperature control needs. Ohio CAT provides 24/7 emergency rental chiller units and service for those unexpected occasions. We will calculate your cooling requirements, then deliver, install, start up and service your setup.
WIKA Instrument Corporation has further reduced water consumption at its Lawrenceville, GA., pressure and temperature instrumentation manufacturing facility from 70 to 78 percent from May 2007 to December 2009. The entire hydraulic/product quenching cooling system is fed from two plate & frame heat exchangers inside the plant on a closed loop recirculating system. If you need a new HVAC installation or an HVAC retrofit, Air Comfort’s team of experts can help you select the right chiller for your system. Reach out to us today to begin looking for the right commercial or industrial chiller system. At Air Comfort, we work extensively with chiller installation and maintenance, so we can calculate chiller efficiencies for the different types.
