A low temperature glycol chiller machine uses the refrigeration cycle and glycol as an antifreeze fluid to cool products and equipment. Low temperature glycol chillers typically come in different specifications and varieties.
Modular chillers
A modular low temp glycol chiller is designed to be scaled up or down by adding or removing individual chiller modules. Each module has its own independent refrigeration circuit, cooling capacity, and controls. The central cooling system controls how many modules are active at any given time based on the current cooling demand. This way, modular low temperature glycol chillers can provide precise temperature control and flexibility. In addition, they are typically more energy efficient than conventional cooling systems.
Split chillers
Low temperature split chillers are composed of two distinct units: the condenser and the evaporator. These units are interconnected by piping. The evaporator unit is typically mounted indoors near the application being cooled, while the condenser unit is installed outdoors. This allows for the easy separation of heat-generating components from areas requiring cooling. In addition, low temperature split chillers can offer high-efficiency cooling solutions across a wide range of industrial and commercial applications.
Centrifugal chillers
Centrifugal chillers with low temperature glycol are typically used in larger cooling applications. Their refrigeration cycle is driven by centrifugal compressors. Besides, low temperature centrifugal chillers have higher efficiency and greater cooling capacity, making them ideal for large commercial buildings, industrial facilities, etc. In addition, these centralized cooling systems can chill large volumes of liquids and refrigerants at a low temperature.
Scroll chillers
A scroll chiller works by compressing gas refrigerants using two spiral-shaped scrolls. The refrigerant is then cooled and condensed within coil systems. Low temperature scroll chillers can offer repeatable, precise cooling. Also, they can effectively cool a variety of equipment and processes in industrial, manufacturing, and commercial settings.
Low temperature glycol chillers are available in various specifications to suit different industrial needs. Here are some key specifications to note:
Capacity
The capacity of a glycol chiller is expressed in tons or kilowatts. It indicates the amount of heat the chiller can remove from the liquid per unit of time. One ton of cooling capacity is equivalent to the removal of 12,000 BTUs (British Thermal Units) of heat per hour. For example, a chiller with a 10-ton capacity can remove heat equivalent to 120,000 BTUs in an hour.
Temperature Range
A glycol chiller can operate within a specific temperature range. The evaporator or cooling component of the chiller typically has a temperature range of 0 to -60 degrees Celsius. This means the chiller canCool down liquids and substances to as low as -60 degrees Celsius.
Refrigerant
Glycol chillers use different types of refrigerants to cool liquids. Common refrigerants include R-22, R-404A, and R-134A, among others. Some pollutants have been phased out or are being considered for phase-out due to their impact on the ozone layer and global warming. For instance, refrigerant R-404A is frequently utilized in industrial cooling applications because it is suitable for low-temperature cooling needs.
Compressor
A glycol chiller's compressors type and power directly impact the chiller's performance. A chiller may be equipped with a reciprocating, screw, or scroll compressor, amongst other compressor types. The cooling capacity of a chiller is usually expressed in horsepower (HP) or kilowatts (kW). For example, a chiller equipped with a 20kW compressor can effectively cool down liquids and substances at a rate equivalent to its motor power.
Like any other machine, low temperature glycol chillers require maintenance to run smoothly for long periods and efficiently. Here are some of the essential maintenance tips for a glycol chiller:

One may consider some factors when selecting a low-temp glycol chiller for a particular application. First, it is essential to determine the required cooling capacity of the chiller. When calculating the ideal cooling capacity, one needs to analyze the heat load of the system or process that the chiller will be servicing. Consider the factors that contribute to the heat load, such as the ambient temperature, the amount of equipment generating heat, and insulation.
The second step is to determine the lowest temperature one is willing to achieve in the system or process that the cooler will be circulating glycol to maintain. Some chillers can achieve temperatures as low as -50°C. Once these two crucial things are determined, it becomes easier to choose a chiller that will be most efficient for the application at hand. If unsure, it may help to consult an expert or manufacturer to prevent costly mistakes.
These factors will also help narrow the range of coolers to those that are suitable for the application. While considering different coolers, pay attention to the refrigerant used in the chiller. Some refrigerants have better heat-transfer properties than others. Typically, R-134A, R-410A, and R-404A are common refrigerants used in low-temperature chillers. Also, consider the type of chiller that will work best for the system one is operating. Whether a continuous-process chiller or an intermittent one, only suitable types need to be considered to simplify the decision-making process.
Finally, one needs to consider the maintenance requirements of the coolers being considered. Some coolers will require frequent servicing, while others will need less maintenance to operate efficiently throughout their lifespan. Also, while making a decision, it may help to consider the amount of space available for the chiller. Some cooling systems are compact, while others require significant space. Remember to always request the cooling system’s documentation and service manuals before making a purchase.
Q1 Are glycol chillers used in cold weather?
A1 Yes, glycol chillers are commonly used in cold climates. They work effectively in freezing temperatures by cooling process water. As a result, the water is kept at a temperature below the freezing point, preventing ice formation. This ensures continuous operations, even in frigid conditions.
Q2 What is the difference between glycol and water chillers?
A2 A glycol chiller uses a mixture of glycol and water as a coolant. In contrast, a water chiller uses water alone. Pure water is prone to freezing in low-temperature environments. Therefore, glycol chillers are suitable alternatives to water chillers. Moreover, glycol coolants offer businesses benefits such as operating in different environmental conditions and reducing the risk of corrosion.
Q3 Does a glycol chiller require water to operate?
A3 No, a glycol chiller does not require water to operate. The chiller uses coolant fluid. It circulates through the evaporator, condenser, compressor, and valve. The coolant absorbs heat from the environment. It then transfers heat to the atmosphere.
