Things to Consider When Buying a Chiller

Things to Consider When Buying a Chiller

Are you looking for a new chiller for your workplace? Are you confused about which chiller to buy such that it fulfills your needs? Taking such an important decision like this one is a daunting task for any engineer or business owner. The wrong decision can waste both time and money.

Let’s discuss this issue in detail.

Taking the Decision

Before actually visiting the market and buying a chiller, it is of vital importance to determine the kind of chiller that you need. You can either go for a water-cooled chiller or an air-cooled one. If your goal is to upgrade an existing unit, you will have to replace it with the same kind of chiller. On the other hand, if you are about to handle a new installation, you need to spare a moment to reconsider your options. 

It is important for you to understand the difference between a water-cooled chiller and an air-cooled chiller. Remember, these chillers are named upon the kind of condensers they use. An air-cooled chiller has a self-contained system and requires no outside units. Unlike a water-cooled chiller, an air-cooled chiller is easy to install.

When it comes to water-cooled chillers, they need a cooling tower along with a cooling tower supply pump to cool the water. If you have a cooling tower on the plant, you best option is to go for a water-cooled chiller.

Now that you have chosen between the two types of chillers, the real game begins.

Screw Chillers VS Scroll Chillers

Choosing between scroll and screw chiller is yet another challenging task. If you are looking for smaller chiller go for a scroll chiller. However, if you need something bigger, choosing between the two can become a little tricky. Here are some things that you need to consider.

·         Scroll compressors are small when it comes to size. However, with the advancement in technology, bigger compressors are becoming available. For a larger load, you will require multiple compressors. Never make the mistake of running them all on a single circuit. Doing so will cost you heavily in the long run.

·         Screw compressors can range from 30 HP to 500 HP. For that size, there is no air-cooled condenser, big enough for its accommodation. It can only work with a water-cooled chiller. These compressors are perfect for the job when it comes to larger areas.

·         Scroll compressors work best with smaller applications. They can run for long hours depending upon the size of the place they are supposed to work in.  If you need to run a chiller 24/7, it is better to go with a screw chiller.

Choosing an Evaporator

Choosing the right evaporator for your chiller is an important decision to take. For any application beyond 20 tons, it is wise to go for a DX Shell and tube evaporator instead of a brazed plate. A brazed plate evaporator lacks the ability to handle fouling, although it has copper brazing and stainless steel. Shell and tube evaporators, on the other hand have a longer lifespan and better durability.
