Topstar contributes to the progress of industrial refrigeration by producing high-performance water chillers.
Air-cooled water chiller:
An air-cooled chiller uses the heat transfer between the water and air to cool the water. More specifically, the condenser in an air-cooled chiller takes heat from the refrigerant and releases it into the air with the help of a fan. Air-cooled water chillers are useful for small to medium facilities or where there's a limited amount of space.
Water-cooled water chillers:
A water-cooled chiller is a machine that discharges heat from the refrigerant with the assistance of water. Water-cooled water chillers need water sources and cooling towers to function properly. They are a suitable option for large facilities with high heat-extraction requirements.

TOPSTAR chillers come with a full set of specifications that business buyers can study to help them make a decision. Besides this, they will also need to know how to maintain water chillers in good condition so that their investments can last for a long time.
Here are some key water chiller specifications along with ways to maintain them:
Cooling capacity
Typically, chillers are capable of producing a lot of cooling power. This is known as their cooling capacity and is measured in kilowatts (kW) or tons. To maintain the water chillers, the users should monitor the capacity regularly to ensure that it stays at the optimal levels.
Compressor type
A TOPSTAR chiller's compressor will vary depending on the model and application. It may be a centrifugal, scroll, screw, or reciprocating compressor. Business users must choose the right type of compressor for maintaining optimal operating conditions.
Operating temperature range
A TOPSTAR water chillers will have a specific temperature range within which it should be operated. Users should avoid exposing the chillers to extreme temperatures to keep them working efficiently.
Refrigerant
Modern chillers use eco-friendly refrigerants like R410A or R134A, not older ones like R22. The users should check for leaks and do any required repairs to avoid loss of the refrigerant and maintain the refrigerant level.
Power requirements
A chiller will come with a voltage rating and power it will require. Users should ensure that the power supply is stable enough to avoid causing any damage to the compressor and other components.
Reservoir tank
This is the water reservoir in the chiller. It will have a specific capacity. The users should monitor the reservoir's water level and always keep it within the recommended range to avoid overheating.
Dimensions and weight
A water chiller will have a certain size and weight that determines its installation requirements. When transporting or handling the chiller, users should follow standard procedures to mitigate any risks of damage.
The chilling machine is widely used in different industries.
Industrial process cooling
A Topstar water chiller is used to maintain a consistent temperature during different manufacturing processes, which can help improve product quality, reduce defects, and enhance overall operational efficiency.
Injection molding chiller
Topstar water chillers are commonly used in the plastics industry to cool injection molding machines. By controlling the mold temperature, they can expedite cooling time, enhance molding accuracy, minimize thermal distortion, and increase production efficiency.
Machine tool cooling
Topstar water chillers can be used to cool machine tools such as CNC machines, lathes, and milling machines. The precise temperature control helps to maintain the stability of the machining process, reduce tool wear and extend the service life of the machines.
Laser machine cooling
Laser devices, such as laser cutting, marking, and engraving machines, generate a considerable amount of heat during operation. A water-based cooling system is employed to efficiently dissipate this heat, thereby maintaining optimal operating temperatures for the lasers. This helps to ensure their stability, precision, and uninterrupted performance.
Oil cooling
Topstar water chillers can be used to cool oil in various applications, such as hydraulic systems, lubricating systems, and chemical processes. Chilling the oil can help improve system performance, reduce wear, and extend equipment life.

The Topstar water chiller can be used to cool equipment and processes in the food and beverage industry, such as cooling fermentation tanks, pasteurized, and heat exchangers. It helps ensure food safety, comply with sanitary standards, and improve processing efficiency.
Medical and pharmaceutical manufacturing
In the medical and pharmaceutical manufacturing industry, the Topstar water chiller is commonly used to cool equipment and processes. This includes cooling down fermentation tanks, reactors, and fermentation vessels, among other equipment. The device plays a crucial role in maintaining optimum temperatures, ensuring product integrity, and adhering to industry regulations.
HVAC systems
Topstar air chillers specialized for commercial applications can be used as key components in centralized HVAC systems. They are responsible for removing heat from the circulating water, thereby facilitating the functioning of air conditioning units and heat exchangers to ensure indoor thermal comfort.
When choosing a water cooler, buyers need to pick water chillers that will meet the specific requirements of the applications in which they will be used. Some of the factors they should consider include:
Heat Load:
Heat load is the amount of heat that needs to be extracted from a process or equipment to maintain a desired temperature. To determine the heat load, one has to consider factors such as the amount of heat generated by the equipment, the ambient temperature, and the temperature of the liquid being used to cool the equipment. Once the heat load has been determined, buyers should select water chillers with sufficient cooling capacity to handle the heat load.
Operating Temperature and Pressure:
Different processes require different operating temperatures and pressures. When choosing a water chiller, it is important to consider the temperature and pressure range. Select a chiller that can operate within the required temperature and pressure range.
Energy Efficiency:
Energy efficiency is an important consideration when choosing a water chiller. Water chillers consume a significant amount of energy, and selecting an energy-efficient chiller can help reduce operating costs. Buyers should look for water chillers with high-efficiency ratings, such as those that meet or exceed the demanded energy standards.
Condensing Unit:
Choose an appropriate water chiller condenser for the specific application. Air-cooled condensers are commonly used in applications where ambient air can be utilized for heat rejection. On the other hand, water-cooled condensers are preferred in applications that require high cooling capacities or where space constraints exist.
Noise Levels:
The noise level of a water chiller can be a significant concern, especially in residential or noise-sensitive areas. Buyers should consider the chiller's location and choose one with a low noise level if applicable. Also, consider acoustic enclosures and other sound attenuation devices to minimize noise hazards.
Cost:
The initial purchase cost and ongoing operating costs of a water chiller are important considerations for many buyers. While it is important to choose a chiller that fits the budget, it is equally important to select one that will provide reliable performance and low-maintenance costs over its lifespan.
Q1: How long can a water chiller last?
A1: Generally, if well maintained, industrial water chillers typically last around 10 to 15 years.
Q2: What are the benefits of water chillers?
A2: Water chillers regulate temperatures to prevent expensive equipment from overheating. They are essential for maintaining optimal operating conditions. Water chillers improve product quality and increase the prominence of the air conditioning systems to allow the same equipment to be used at different commercial refrigerant inputs.
Q3: What type of water chiller is more efficient?
A3: The centrifugal chiller is widely considered the most efficient technology for large capacity cooling applications typically greater than 300kW.
Q4: Do water chillers use a lot of electricity?
A4: The average water chiller consumes approximately 25 kilowatts per hour when running. However, the amount will vary depending on its size and specifications.
