Five Things to Consider When Selecting an Industrial Chiller

Industrial chillers are critical equipment in manufacturing, as they are essential in minimizing the threat of production downtime or product quality contamination that may be caused by excess heat in a process or application. Specifically, industrial chillers protect a process&#; integrity by removing excess heat from equipment and applications that are sensitive to high temperatures; examples include those in the food and beverage, plastics, and printing industries. By using and re-circulating a facility&#;s own water supply, industrial chillers also help to decrease a plant&#;s water consumption, lower the costs associated with cooling water, and bypass the need to have access to a municipal water supply and wastewater discharge system.

Things to Consider When Selecting an Industrial Chiller

Thinking of specifying an industrial chiller installation for your facility? There are five key items that you should consider to ensure that you select the right product: the type of process fluid that will be used; the process cooling temperature; the pressure and flow requirements; the operating environment; and the chiller size needed.

Process Cooling Fluid. When you&#;re choosing a cooling fluid for your process, you should consider both how a fluid performs and its equipment compatibility. The performance of a specific fluid is based on its properties at a given temperature, such as specific heat, viscosity, and its freezing and boiling points. When considering equipment compatibility, be sure to consider both the materials and fluids being used, given that the potential for corrosion and early seal degradation commonly happen in incorrectly sized systems.
Cooling Fluid Temperature. Know your chiller&#;s performance data! A chiller&#;s cooling capacity is directly affected by the setpoint temperature, meaning that a direct relationship between the temperature at which the chiller is set and its total cooling capacity. A decrease in temperature will put an increased load on the refrigeration system, while increasing the temperature will do the opposite.
Process Pressure and Flow Requirements. Did you know that a pump&#;s size and performance help to determine a system&#;s pressure loss, as well as its necessary flow rate? That&#;s right!

Pressure. To determine the pressure loss across a system, place pressure gauges at the process&#;s inlet and outlet and then apply pump pressure to obtain the values at the desired flow rate. Keep in mind that an undersized pump will reduce the fluid flow rate through the entire cooling loop. If the chiller has been equipped with internal pressure relief, the flow will be diverted around the process and back into the chiller. If there is no internal pressure relief, the pump will attempt to provide the necessary pressure and run at what is referred to as dead-head pressure, or limit. When this state occurs, the pump&#;s life can be drastically reduced; liquid ceases to flow and the liquid in the pump becomes hot, eventually vaporizing and disrupting the pump&#;s ability to cool. This results in excessive wear to bearings, seals, and impellers.

Flow. Inadequate flow through the process will yield inadequate heat transfer so the flow will not remove the heat necessary for safe operation of the process. As the fluid temperature increases beyond the setpoint, the surface/component temperatures also will continue to rise until a steady-state temperature that is greater than the initial setpoint is reached.

Operating Environment. Knowing the site conditions of where your chiller will be operating is essential to selecting the best product fit for your process! Ambient temperature and spatial constraints are especially important to consider.

Ambient Temperature. An air-cooled chiller&#;s ability to dissipate heat is affected by the ambient temperature, as the refrigeration system uses the ambient air/refrigerant temperature gradient to induce heat transfer for the condensation process. A rising ambient air temperature decreases the temperature differential (Δ) which reduces the total heat transfer. If the chiller uses a liquid-cooled condenser, high ambient temperatures can still have negative effects on key components such as the compressor, pump, and electronics. These components generate heat during operation, and elevated temperatures will shorten their lifetime. As a guideline, the typical maximum ambient temperature for non-exterior rated chillers is 104° fF

Spatial Constraints. To maintain the proper ambient air temperature, it is important to provide adequate air circulation space around the chiller. Without proper airflow, recirculation of an inadequate volume of air rapidly heats it up. This will impact chiller performance and potentially can damage the chiller unit.

Chiller Size. Selecting a correctly sized chiller is a crucial decision. An undersized chiller will always be a problem &#; never able to properly cool the process equipment and the process water temperature will not be stable. In contrast, an oversized chiller will never be able to run at its most efficient level and prove more costly to operate. To determine the correct size of unit for the application it is necessary to know the rate of flow and the heat energy that the process equipment is adding to the cooling medium, i.e., the change in temperature between the inlet and outlet water, expressed as the &#;T.

CHOOSING A CHILLER: 5 FACTORS TO CONSIDER

When it comes to chillers, figuring out where to start is the tricky part. Air-cooled or water-cooled? Used or new? What size do you need? The experts at Cold Shot Chillers cover all of these questions and more in today&#;s article.

What Are Industrial Chillers?

An industrial chiller is a refrigeration system that keeps equipment and materials cool, allowing operations to run smoothly. Air Conditioners dehumidify air while water chiller systems cool down fluids that can be used to condition spaces or cool processes, simply by removing heat. However, these units are not &#;cooling&#; or &#;chilling&#; anything; they simply remove heat.

Factors to Consider for Your Chiller Choice

There are a few general rules of thumb to keep in mind when selecting a new cooling system. Keep reading to gain a better understanding of the different chiller types available on the market.

1. Size

Size is one of the biggest factors to consider when buying a chiller. Selecting a correctly sized chiller is paramount. A chiller that is too small won&#;t properly cool your equipment or materials. On the other hand, a chiller that is too large will work just fine, but providing excess capacity will over time fail prematurely due to short cycling. In addition, you&#;ve spent more money than you needed to. So how do you know what size chiller you need?

Industrial chillers come in a variety of sizes, ranging from ¼ ton to thousands of tons in capacity. We recommend you use a chiller size calculator to determine what size chiller you need for your application. Below are some examples of chiller sizes based on industry standards.

Medical Chillers &#; 7 ½ ton and 5-ton chillers; or 12 ½ and 15-ton chillers for cooling multiple medical devices simultaneously
Welding Chillers &#; it&#;s advised to have at least 1-ton of chilling capacity for 100KVA of welder capacity
Winery Chillers &#; typically, a 2-ton air cooled chiller is sufficient for most winery applications
Waterjet Cutting Chillers &#; common sizes are 2 and 3 ton
Hydroponic Chillers &#; sizes generally range from 1.5 to 100 tons
Flower Chiller &#; sizes range typically from 2-100 tons

Keep in mind that these sizes are only based on industry standards. Manufacturers like Cold Shot Chillers can design and build custom units of virtually any size.

3. Type

Industrial chillers can be categorized in a few different ways. Let&#;s take a look at five types of chiller classifications.

Air Cooled Chillers &#; Air-cooled systems are generally cheaper than water-cooled chillers. However, they tend to release significant amounts of heat, so these chillers are best-suited for facilities where heat is not an issue.
Water Cooled Chillers &#; Water chillers are typically quieter and more efficient than air-cooled chillers. Therefore, they are suitable for commercial-scale and small-scale facilities.
Portable Chillers &#; In this case, the term &#;portable&#; does not refer to the mobility of the chiller. Instead, it means that a chiller contains all the system&#;s basic components in a single footprint.
Stationary Chillers &#; Chillers that are &#;stationary&#; do not include a tank or pump. Instead, they are stand-alone units that must be connected to a reservoir and pump to function.
Central Chillers &#; These chillers are used to cool several processes. They can have a portable or stationary configuration, and they can be air-cooled or water-cooled.

4. Pricing

Industrial chillers can range in price anywhere from hundreds to thousands of dollars. As mentioned before, water chillers are typically more expensive than air-cooled chillers. In addition, different chiller manufacturers all design and price their systems uniquely, so make sure to carefully compare prices and weigh your options before making a purchase.

5. Manufacturer

Always familiarize yourself with the manufacturer and their policies ahead of time. Ask the following questions and more before choosing a chiller:

Do they offer a chiller warranty?
What&#;s the turnaround time?
How are new chillers tested?
Do they offer chiller accessories and tools?
How is the chiller prepped for shipment?
Has the company been around for a while? The longer a company has been in business chances are good the company is reputable and trustworthy.
Does the chiller design use any proprietary components? That replacement part might carry a high price tag since these types of parts are generally used to control the chiller. Over time these items become obsolete and no longer supported.
How easy is it to reach a live person? Can you get technical and commercial issues resolved over the quickly?
Has the chiller manufacturer built a chiller handling the same type of application or something similar?
Does the chiller company make it easy to do business with? Can you discuss your application with a knowledgeable technical representative? Can you get a quote issued for your project quickly? Does the submittal information include everything you need about the chiller you are considering?
Deal directly with the manufacturer to cut out the middleman. This will alleviate any confusion on how your chiller should be configured and possibly save some time and money.
