Discover how to cut energy costs with free cooling chillers and what aspects should be considered when selecting a free cooling system. Lightstream family of air-cooled chillers running on refrigerant R515b represents the next advance in eco-friendly cooling technology while contributing to performance improvement. Highest reliability of our chillers achieved by intelligent engineering and assured through the use of time-proven components, maximum manufacturing quality, and thorough equipment testing. This post covers three angles namely installation, maintenance and operating cost. If noise is a primary concern, then water-cooled chillers are the way to go. Noisy HVAC machines can be an annoyance, especially in buildings occupied by doctor’s offices, call centers, or other business offices. They are also popular where there isn’t ample air recirculation. Any obstructions adversely affect the performance of air-cooled chillers.

Recording operating conditions such as flow rates, pressures, fluid levels, and temperatures helps build a useful record of your system. While it was standard to do bi-monthly checks today’s continuous monitoring technology allows you to keep accurate daily logs that will help you narrow down maintenance issues before there’s a bigger problem. Heat Recovery Chillers from Motivair are designed to optimize overall chiller efficiency by simultaneously producing chilled water and hot water. Chillers used in plastic fabrication typically take on one or both of two roles, cooling the plastic products and cooling the machinery used to make them. The chiller units are also used to keep the barrel of the extruder, and hydraulics of the molding machine cool. This not only saves on energy but it also helps extend the life of the plastic fabrication equipment. Instead of utilizing a mechanical compressor the absorption chillers use a heat source to be the driving force behind the refrigeration cycle. These chillers typically use two liquids, one to cool and one to absorb.

We ran and tested this unit thoroughly in our 13,000 square-foot chiller facility prior to shipping. Arrived at KIG in October 2015 was this 5 hp / 5 ton Air Cooled Chiller Split w/ Remote Condenser. This is a great solution for a manufacturer, or brewery/winery that wants the heat from the process dissipated outside – and chiller, controls, tank, tank etc. in the facility. It uses a Copeland 5 hp compressor and has hot gas bypass and low ambient feature, so this will operate even when 0°F outside. We can configure & run/test unit in our shop at 28°F for your brewery/winery application; equally as fine for a manufacturing operation which uses higher fluid temps. Although run and tested here, the system required field refrigerant piping installed & charge added, as it is SPLIT with the condenser going outside.

Water-cooled chillers require cooling towers, condenser water pumps, and other associated HVAC components. Air-cooled chillers do not need any of these additional building blocks. These complex machines require a lot of maintenance to keep them in good working order. If proper steps aren’t taken, the chiller can corrode, clog, lose efficiency, or experience a number of other issues. For example, if proper water treatment isn’t maintained or if open cooling towers aren’t cleaned, sediment or particulates can be introduced to the system, causing clogged pipes and poor heat transfer. An air-cooled chiller’s condenser can be blocked by debris or become caked in dirt, which also lowers efficiency. Our Tandem Scroll Chillers are designed for efficiency and reliability in medium to high temperature applications.

Air cooled chillers typically do not have as long a service life as water cooled chillers because they are exposed to the sun, rain, frost, snow and wind which deteriorate the materials. Arrived at KIG in October 2014 was this nice Trane RTAA 100 chiller. These units are known as workhorses in the industry, and this particular unit has the low ambient VFD fan drive option to operate in outdoor climate year round. Additionally, this chiller has the factory low fluid temperature “brine” option to handle set point temperatures 0° to 39°F . Arrived in January 2018 to KIG were two Carrier Aquasnap 40 ton Air Cooled Chillers. These units had low hours and were well maintained at a Data Center.

For a dry cooler, thermal exchange is performed by pulling in external air and circulating it over tubes containing a cooling fluid (typically water or water-glycol mixture). The cooled fluid is then circulated through a heat exchanger attached to an associated process. The excess heat transferred to the cooling fluid is then returned to the dry cooler and the cycle is restarted. It is important to note that a dry cooler does not have a standard refrigeration unit which chills a circulating refrigerant. Rather, it uses fans to pull in ambient air to cool its heated fluid medium. Air Cooled Chillers are often an excellent process cooling option to water cooled chillers because they are closed loop systems. Closed loop systems have the ability to offer instantaneous cooling to plant processes as well as offer significant savings in water usage by recirculating coolant/water. If you do not have access to building supply water , and dry fluid coolers are not an option, we offer high efficiency air cooled chillers to be used with our high efficiency air cooled condensers. These condensers can be located on the roof or ground and can be designed to operate in ambients up to 105° F and down to –20° F during the winter months.

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. It has 8 cooling fans, 4 of them with VFD low ambient controller. It has a brazed plate exchanger and utilizes a nice high end 50 hp Bitzer Compressor.

The World Bank puts the number of people living with absolute water scarcity at 2bn, a number that could hit the 4.6bn mark within the next 65 years. The water energy nexus has been a regular subject in recent years. Power plants that feed most nations consume a lot of water, either directly or indirectly. When it comes to the feasibility study of a cooling plant, the debate of consuming water or not is very important. Depending on the results of this study, water-cooled or air-cooled chillers will be selected. We offer factory-run testing for all chillers prior to shipment as a standard option every day. Daikin is devoted to overcoming the evolving challenges of air while creating better, more sustainable outcomes for customers and communities.

Air-cooled chillers, chillers where water used in the chiller gets cooled by releasing heat into the ambient air through condensers, are popular in many industries. They don’t require cooling towers, and they don’t use as much water. However, every company needs something different from their chillers, and that means that you sometimes need to have your chiller customized. Water-cooled condensers perform the same function as air-cooled condensers, but require two steps to complete the heat transfer. First, heat moves from refrigerant vapor into the condenser water. Then, the warm condenser water is pumped to a cooling tower where the process heat is ultimately discharged to the atmosphere. A chiller works on the principle of vapor compression or vapor absorption.

Air cooled and water cooled chillers have many things in common. They both belong to the same vapor compression chilling family, and they both use an electronically driven mechanical compressor to force refrigerant around the system. The main difference between the 2 is how unwanted heat is ejected from the system. Water cooled chillers pump water through a sealed condenser and disperse it through a cooling tower. Air cooled chillers use fans to force cool air across the condenser. Cost is one of the important factors when deciding between air cooled or water cooled chillers.
