Water Cooled Chilllers
The 400-liter chiller circulates water through a cooling coil to absorb heat in the water-cooled version. The chilled water is then pumped throughout the facility for cooling purposes. These chillers are efficient and often used in large systems. Although the setup is quite large and includes a cooling tower or a water reservoir, the appliances are relatively cheap to operate for the company with more significant cooling needs.
Air-Cooled Chillers
Air-cooled chillers utilize ambient air to cool the refrigerant. Fans draw in air, which cools the refrigerant before it enters the compressor. This type of the 400-liter chiller doesn't require water sources for cooling, which is an advantage because it can be installed easily without being set up specifically for the cooling tower and water lines. However, they are less efficient than water-cooled chillers, primarily in high-temperature situations.
Heat Pump Chillers
Heat pump chillers are different from the regular 400-liter chillers, as they can provide heating by reversing the refrigeration cycle. They absorb heat from a low-temperature source and concentrate it to release at a higher temperature. Heat pump chillers are mainly used in locations that need both heating and cooling or as backup heaters in case of failure. They are ideal for R&D centers that require temperature maintenance to avoid damage to their equipment.
Absorption Chillers
Absorption chillers utilize heat (from natural gas, steam, or hot water) instead of electricity to drive the refrigeration cycle. They use an absorbent solution to cool the refrigerant. Absorption chillers are mainly used in facilities that have access to heavy heating sources or wish to reduce their electrical load. Although they are not as effective as compression chillers, they can be used to generate electricity and thus minimize the costs.
Plastics Industry
The 400-liter chiller is mainly used in the plastics industry to control the temperature during molding and extrusion processes. In order to achieve the desired shape, the molds used in plastic injection molding must be kept at a specific temperature. Chillers help avoid overheating, which will lead to material degradation, early wear on the machine, or even production stops, among other things. By maintaining proper temperature, the chiller contributes to producing high-quality plastic components with greater accuracy in the plastic industry and minimal waste.
Printing Industry
In the printing industry, refrigeration is vital for controlling ink and paper temperature during printing processes. Chill 400-liter systems keep inks at optimal viscosities and prevent them from drying too fast or too slowly in offset printing. They also cool printing plates and paper to ensure that the images produced are sharp and clear. Moreover, maintaining this temperature in the printing process helps prevent paper warping, thus improving its quality and consistency. Without adequate cooling, companies in the printing industry will experience decreased production.
Chemical Industry
The chemical business will also need a chiller to control chemicals, solvents, and other compounds' reaction and processing temperatures. If the temperature is not controlled, the reactions in the chemical industry can vary greatly, thus leading to disastrous results, including explosions or the production of toxic substances. Here, chillers absorb heat from chemical reactors, maintaining a safe and desired temperature range. This, in turn, helps improve product safety and quality while reducing the risk of equipment damage and thus increasing efficiency within the chemical facility.
Food Industry
The food industry uses 400-liter chillers to help preserve food by cooling the productions, such as pasteurization, fermentation, and mixing. Chillers maintain bacteria at low temperatures, thus increasing their lifespan. In ice cream production, for example, a chiller maintains the right temperature conditions during mixing to achieve the desired texture. Dairy Fermentation Processes also need temperature control, which can be queried on a chiller. In addition, the food industry relies more on chillers for safety, quality preservation, and compliance with the regulation concerning temperature control.
Die Casting
Chillers control the temperature of molten metal and molds during die casting in the die-casting business. The mold must be cooled uniformly for the molten metal to solidify correctly. Any irregularities in the cooling process will lead to defected castings such as cracks, warping, or incomplete filling the mold. Chillers help extract heat from the mold, which solidifies the metal at a controlled rate. This enhances the quality of the cast products, thus making it indispensable for the die-casting industry to have chillers.
Cooling capacity
The 400-liter chiller has a relatively large cooling capacity; hence, it is suitable for significant industrial applications. The chillers provide precise temperature control by removing heat from fluids at a relatively great rate. The average cooling capacity of a 400-liter chiller can be up to several kilowatts, depending on the particular model and application requirements.

The procedures can include: checking the operating parameters, testing the controls, and balancing the flow, among other things. Commissioning also entails recording the data and making sure that the device meets the manufacturer's specifications. It helps ensure the machine will work at optimum energy for sustainability.
Regular inspections
Regular inspections on the 400-liter chiller in 400 liters are required to seek any possible signs of wear or damage. Since the machine is only operated most of the time, the point at which it will failure is when it is overworked due to negligence of maintenance. Regular schedule by developed checklists can ensure all the components responsible for the functioning are checked.
Heat exchanger cleaning
Keeping the heat exchangers clean will enhance the heat transfer capability, so it is necessary to frequently clean the chiller and avoid the accumulation of debris, dust, and other contaminants. The director also recommends using non-corrosive cleaners and having a water-cooled chiller.
Fan and condenser maintenance
Its fans and condensers should be kept clear and clean, as this affects airflow. Inspect the fan blades for bends and debris and clean the blade. In addition, the condenser coils should be brushed regularly and followed by a coil cleaner to avoid the inefficiency that will be generated by dirty coils.
Regular lubrication
The various moving parts within the 400-liter chiller, such as fans and pumps, need regular lubrication to reduce friction and wear. The lubrication is done by using the manufacturer's recommended grease or oil for the machinery, as improper lubrication will affect the parts, leading to a chiller breakdown.
Re-calibrate periodically
Calibration of the controls and sensors at regular intervals ensures they provide accurate readings. If left for a long time without recalibrating them, they will give erroneous information, which will, at some point, affect the chiller's performance or even lead to over or under-conditioning of the items.
Heat Exchanger Leaks
Any form of leakage in the heat exchangers is considered one of the most critical fixes since it will interfere with the chiller and cooling process. However, when there is a leak, the refrigerant will escape, which will affect the machine's overall production. In many instances, smaller leaks can be fixed using sealants; in extreme cases, exchanger replacements will be needed. The manufacturers are the best source of identifying this problem and fixing it.
Compressor Issues
As one of the most important parts, anything that hinders the functioning of an organic compressor results in poor chugging performance. Problems such as noise, overheating, and frequent cycling may all come down to issues such as worn mechanical parts, electrical failures, or faulty valves. A good way to fix it is by replacing the damaged components. In the worst case, an old compressor will need to be replaced if it was servicing the unit for many years.
Electrical Failures
Electrical failure, mainly wiring issues or faulty sensors, is another common problem when it comes to the cooling chiller 400 liters. If not addressed early enough, these issues may cause much larger problems or even lead to the shutdown of the operations. Repairing electrical problems involves rewiring faulty components and replacing some damaged parts. Ideally, electrical work should be done by qualified personnel so as not to compromise the unit.
Contaminated Filters
Filters that have too much dirt and debris not only affect the air and refrigerant flow but also lead to the parts working harder and, in turn, easier to wear out. Exposure to dirt can cause more significant problems, such as mechanical failure. Contaminated filters should be replaced immediately or cleaned to prevent damage to the machine.
