Main Components of a Process Chiller

An Industrial Process Chiller is made up of several essential components that work together to regulate temperature and ensure smooth operation. Each part plays a crucial role in the refrigeration cycle:

Compressor:
This is the heart of the chiller. It compresses the refrigerant gas, increasing its pressure and temperature so it can move through the system efficiently. Types of compressors include scroll, screw, reciprocating, and centrifugal, depending on the chiller’s capacity and design.
Evaporator:
The evaporator is where the process fluid (such as water or glycol) passes through and loses its heat to the refrigerant. This is where heat absorption occurs, and the refrigerant turns into a gas.
Condenser:
After compression, the hot refrigerant gas flows into the condenser. In this component, the heat is removed either by air (air-cooled) or water (water-cooled), and the refrigerant changes back into a liquid.
Expansion Valve:
The expansion valve regulates the flow of refrigerant into the evaporator. It reduces the pressure and temperature of the liquid refrigerant before it re-enters the evaporator to absorb more heat.
Process Pump & Reservoir:
A circulation pump pushes the cooled fluid to the process and brings the warmed fluid back to the chiller. The reservoir holds the process fluid and acts as a buffer to handle thermal loads.
Control System:
Modern chillers come with advanced control panels and sensors that monitor and regulate temperatures, flow rates, pressures, and operating parameters for safety, efficiency, and precision.
Together, these components form a reliable and energy-efficient system that keeps industrial operations stable, regardless of heat-generating activities within the facility.

Types Of Refrigerant Valves

An Electronic Expansion Valve (EEV) is a high-precision device used in modern refrigeration and HVAC systems to regulate the flow of refrigerant into the evaporator. Unlike traditional mechanical valves, EEVs respond to electronic signals from temperature and pressure sensors, enabling dynamic and accurate control of superheat levels. This results in enhanced energy efficiency, faster system response, and improved temperature stability, even under varying load conditions.

EEVs are ideal for applications that demand consistent performance and tight control—such as commercial refrigeration units, VRF systems, chillers, and data centre cooling setups. Built for compatibility with smart controllers, these valves help optimise system operation and reduce energy costs. Their compact design, low maintenance needs, and remote programmability make Electronic Expansion Valves a preferred choice for advanced and energy-efficient cooling systems.

A Thermostatic Expansion Valve (TXV) is a vital component in refrigeration and air conditioning systems, designed to regulate the flow of refrigerant into the evaporator. It maintains optimal superheat by responding to temperature and pressure changes at the evaporator outlet, ensuring efficient heat transfer and preventing liquid refrigerant from returning to the compressor. TXVs help enhance overall system performance, reduce energy consumption, and protect critical components from damage.

Thermostatic Expansion Valves are widely used in residential AC units, commercial refrigeration systems, chillers, and cold storage applications. Known for their durability and reliability, TXVs offer stable performance under a variety of operating conditions. Available in various sizes and configurations, they are compatible with a range of refrigerants and system designs—making them a trusted solution for both new installations and retrofits.

Filter-Driers play a crucial role in HVAC and refrigeration systems by removing moisture, acid, and particulate contaminants from the refrigerant. These components protect compressors and other system parts from corrosion, freezing, and clogging—extending equipment lifespan and ensuring optimal performance. Whether used in air conditioning units, refrigeration systems, or heat pumps, filter-driers help maintain system efficiency and reliability.

Available in both replaceable core and sealed types, filter-driers come in various sizes and designs to suit different system capacities and refrigerant types. They are essential during initial installation, maintenance, or after a compressor burn-out, as they prevent damage caused by impurities in the system. With high moisture-absorption capacity and low pressure drop, filter-driers are a dependable choice for clean, dry, and trouble-free refrigerant flow.

Sight Glass is an essential diagnostic component used in refrigeration and air conditioning systems to visually monitor the flow of refrigerant and detect moisture levels. Installed in the liquid line, it provides a clear indication of system conditions—such as refrigerant charge status, presence of bubbles, and moisture contamination—helping technicians ensure optimal operation and perform quick troubleshooting.

Sight glasses are available in various configurations with features such as moisture indicators, hermetically sealed construction, and high-pressure resistance. These units are widely used in commercial refrigeration systems, industrial chillers, and HVAC applications to improve system visibility and maintenance accuracy. By offering a real-time view into refrigerant quality and flow, sight glasses contribute to efficient system performance and long-term equipment reliability.

Solenoid valves are electromechanically operated devices used to control the flow of liquids or gases in HVAC, refrigeration, and industrial systems. These valves open or close automatically when an electric current is applied to the solenoid coil, offering precise, fast, and reliable flow regulation. They are widely used in applications such as refrigerant control, water treatment, compressed air systems, and automated manufacturing processes.

Solenoid valves are available in a variety of sizes, materials, and configurations—such as normally closed, normally open, direct-acting, and pilot-operated—to suit different pressure ranges and media types. Their compact design, quick response time, and low energy consumption make them ideal for automated and remote-controlled systems. Designed for durability and high performance, solenoid valves help improve system efficiency, safety, and ease of maintenance.

A 4-Way Reversing Valve is a key component in heat pump systems, enabling the switch between heating and cooling modes with ease. By reversing the flow of refrigerant, this valve changes the direction of heat transfer—allowing a single system to provide both heating in winter and cooling in summer. It ensures year-round climate control efficiency in residential, commercial, and industrial HVAC applications.

Built to handle varying pressure conditions and refrigerants, 4-way reversing valves are compact, reliable, and compatible with a wide range of compressor types. Their design allows for smooth operation and minimal energy consumption while maintaining consistent indoor comfort. Whether you’re installing a new heat pump or replacing an existing valve, this component plays a crucial role in enhancing overall system flexibility and performance.

Refrigerant Ball Valves are essential components in refrigeration and HVAC systems, designed to provide secure and leak-proof shut-off for refrigerant flow. Featuring a full port design and a quarter-turn operation, these valves allow for smooth, unrestricted flow and easy isolation of system components during maintenance, installation, or emergency shutdowns. They are suitable for use with various refrigerants, including R-22, R-134a, R-410A, and more.

Built from high-quality brass or stainless steel, refrigerant ball valves offer high durability, corrosion resistance, and pressure tolerance. They are commonly used in commercial chillers, cold rooms, VRF systems, and industrial cooling applications. With features like extended stems for insulation clearance, bi-directional flow, and reliable sealing, these valves enhance system safety, efficiency, and serviceability.
