Everything You Need to Know About Scroll and Reciprocating Chillers

Written by Coolstar India  »  Updated on: May 28th, 2025

Reciprocating chillers employ a piston-driven compressor to cool a refrigerant. They are often less costly than other types of chillers, such as scroll or screw chillers, and have a wide working temperature range, making them appropriate for a variety of applications. However, they are louder and need more maintenance than other types of chillers.

Chillers are the most typical piece of equipment seen in significant business locations. These chillers, which have been scientifically designed, have both advantages and disadvantages. Today, in this article, we will discuss reciprocating chillers and the benefits they offer. Before we go into the article, let us define a reciprocating chiller.

What are Reciprocating Chillers?

These chillers are made up of one or more assemblies that include a scroll or reciprocating compressor-motor, an insulated liquid cooler, and a water or air-cooled condenser.

Reciprocating chillers are available in open, semi-hermetic, and fully hermetic configurations. They are typically tested, produced, charged, factory-built, and supplied in a single assembly up to roughly 200 tons capacity. Their installation includes return chilled water pipe and piping supply (and cooling water piping if relevant), connectivity of external controls and power cabling, charging and evacuation when needed, start-up, and check-out. Furthermore, some units lack a condenser and need field plumbing to a distant evaporative or air-cooled condenser.

How do reciprocating chillers work?

Reciprocating chillers function in a very easy manner. They employ pistons that rotate back and forth to compress a particular liquid known as refrigerant. This cooled liquid is then circulated through the system to keep everything at the proper temperature. It's like having a supercharged ice pack for large machinery!

Different types of reciprocating chillers

Air-cooled reciprocating chillers.

Because of their remarkable energy efficiency, air-cooled chillers may run in even the most intense tropical conditions without sacrificing cooling quality. Their creation and testing adhere to tight rules established by regulating agencies worldwide. Installing and utilizing them is simple.

Water Cooled Reciprocating Chillers

This water-cooled chiller is engineered to operate well even under the most harsh weather situations. It is ecologically friendly and uses energy efficiently. International standards are evaluated during the review process. Fluid temperatures and other parameters are crucial in this business, which is why they are employed in this manner. They may be adapted to specific needs.

Industrial Reciprocating Chillers

Industrial Reciprocating Chillers can be found in industrial environments where one application differs significantly from another. Process fluids play an important part in the materials used to manufacture them, which are selected under the expert's supervision.

Advantages of Using Reciprocating Chillers

  • Different condensing solutions are offered, including low ambient and air-cooled operation.
  • Use eco-friendly refrigerants.
  • These chillers offer higher part-load efficiency.
  • Many reliable sources, preferably through factory-approved service providers or a network of expert technicians.
  • These chillers are factory-packaged for quick and precise installation.

Applications for Reciprocating Chillers

Reciprocating chillers are adaptable cooling systems utilized in a wide range of applications, including building air conditioning and industrial operations such as food processing, manufacturing, and data centers. They are also widely used in hospitals, commercial buildings, and for specialized applications like as active pharmaceutical component manufacture and microbreweries.

Reciprocating chillers are a popular choice for central systems in medium to small buildings, as they provide chilled water for air conditioning. They are utilized in a variety of industrial situations that need precise temperature control, including food processing, metal polishing, and injection molding. To keep delicate equipment at the proper temperature, data centers frequently use reciprocating chillers.

The optimum applications are high-quality installations that require central hot or chilled water systems to manage the humidity and temperature of various regions.

Retrofit applications – Several versions will fit through a 30-inch door, making installation easier and requiring fewer structural alterations.

What Are the Different Technology Types?

Scroll compressor packages are the most recent advancement in positive displacement compressors, and there are indications that they may deliver improved efficiency and dependability. The network of professional technicians or service providers is currently expanding and may not be accessible in all areas.

On the other hand, reciprocating compressor packages have long been the backbone of this industry, with several innovations and enhancements throughout the years. These are widely used, and competent service personnel are readily accessible at practically every site.

The Efficiency of Reciprocating Chillers

 The efficiency of earlier water-cooled chiller models ranges from 0.82 to 1.0 kW per ton, whereas newer units range from 0.78 to 0.85 kW per ton under ARI settings.

Installation and maintenance of reciprocating chillers.

To ensure that reciprocating chillers perform well and last a long time, they must be properly installed and maintained. First and foremost, ensure that the chiller is the proper size and location for optimal operation. Furthermore, doing regular maintenance tasks such as cleaning, applying lubrication, and inspecting all components is critical to keeping it working properly.

It would be ideal if you could additionally set it in a location where it can do its function flawlessly. This entails considering factors such as ventilation and heat source.

Wrap Up

Reciprocating chillers are excellent choices for chilling a variety of items efficiently, consistently, and affordably. Whether chilling gear in factories or keeping your house comfortable, these chillers are top-notch in terms of energy efficiency, flexibility, and reliability.
