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. We highly recommend using a chiller sizing tool with exact measurements for the most accurate estimation. You can also reach out to our experienced team for additional help with sizing requirements or general questions.

2. Application

Chillers have various applications for all types of industries. For example, they are used for medical applications such as radiotherapy, PET scans, laboratory operations, and even blood bank refrigeration. In addition, MRI chillers and CT chillers are used frequently in the healthcare sector.

Food processing chillers serve a variety of applications in the food and beverage industry. Depending on your specific setting, you can choose from bakery chillers, winery glycol chillers, brewery glycol chillers, dairy milk chillers, and even commercial yogurt machine chillers.

Metal finishing chillers can be beneficial for paint and powder coating, anodizing, die casting cooling, furnace cooling, quench cooling, and more.

Explosion-proof chillers are commonly used in chemical processing plants, coal plants, oil and gas refineries, and other work environments that interact with flammable gases and vapors.

Cold Shot Chillers offers additional industry-specific chiller types, including laser chillers, plastic processing chillers, government and municipal chillers, welding chillers, and more.

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.

How to choose the proper water chiller for you

After having named the immersed coil and the ice bank as refrigeration means, we consider it useful to focus on the plate heat exchanger. This is a known and consolidated technology in many industrial fields, but rather recently introduced in the world of baking.

The plate heat exchanger is made up of a series of stainless steel blades, between which alternate (and obviously separate) gas and water flow in the opposite direction to maximize heat exchange.

The exchange surface is optimized and much wider than the coil and the refrigeration process is therefore faster and more efficient.

These coolers, also called semi-continuous, have a suitably sized tank, capable of containing at least the water necessary for the single batch into the mixer, but not so large as to waste energy to cool water that will not be immediately used. This ensures that the water remains in motion and does not stagnate. In the event that water withdrawals are rare, the water is still kept in motion by the cooling hysteresis, which keeps the recirculation and the refrigeration cycle constantly active.

Furthermore, as is intuitive, the dimensions are rather small and the important dimensions typical of the oversized tanks of the accumulation models are avoided.

The hourly production of semi-continuous (or batch) chillers is always higher than the tank capacity and is scalable. In the case of the STM offer, for example, models of 150 l/h and l/h are available, with tanks ranging from 50 to 300 liters.

A final aspect that is useful to underline concerns hygiene: on the most recent models, such as the STM Touch Water Chiller series, the automatic washing function is available, thanks to which maximum hygiene of the entire tank is ensured, as well as preventive maintenance of the circuit which increases its durability and useful life.

However, the functionality of automatic washes is not the only advantage offered. If you want more details on programming self-ignitions, remote assistance and safety systems, you can refer to the article dedicated to Electronics, a real secret helper in baking.
