3 ton air cooled chiller

Types of 3 ton air-cooled chillers

A chiller is an industrial machine used to cool liquids through a refrigeration process. It is one of the main components of a cooling system. Water is the liquid coolant in a 3 ton air-cooled chiller.

Air-cooled chillers are widely popular in the industrial machinery market due to their ease of use and low maintenance costs. Here are some common types of air-coolers:

• Scroll chiller (w/o heat recovery)

  A scroll chiller uses two spiral components to compress refrigerant gas. One spiral remains stationary, while the other moves in a circular motion, trapping and forcing the gas through the system. A scroll chiller is efficient, reliable, and has fewer moving parts than reciprocating compressors. It's commonly used in commercial buildings, factories, and industrial processes. Also, unlike traditional compressors, a scroll chiller does not have to be lubricated with oil, which allows the refrigerant to stay completely pure and clean.

• Scroll chiller (w/ heat recovery)

  It is a machine that captures waste heat produced during the cooling process and recycles it for useful applications, such as heating water or supporting other processes within the facility. This type of scroll cooler recovers heat through a condenser that uses recovered heat to heat water. The benefit of a heat recovery cooler is that it helps reduce energy costs and carbon emissions by minimizing the need for additional heating equipment.

• Bitzer compressor chiller

  Bitzer compressors are known for their robust design, variable-speed drives, and cutting-edge electronic controls that provide efficient and reliable cooling. A Bitzer compressor chiller can be customized to fit different needs and is used in various industries, such as food processing, pharmaceuticals, and petrochemicals. Air-cooled Bitzer chillers feature IP55 rated drive motors. They come with standard safety features like thermal overload protection.

• Water-cooled condenser

  A water-cooled condenser chiller uses water to absorb heat from the refrigerant, rejecting the heat into the water. This process cools the refrigerant, which then removes heat from the chilled water. A water-cooled condenser is typically installed in an indoor, controlled environment. Water-cooled condensers are very compact, and the heat exchangers integrated into the system allow them to conserve energy.

Specification and maintenance of a 3 ton air-cooled chiller

The 3-ton air-cooled chiller specification varies depending on the functions and uses of different brands. Here are the basic parts for their specification.

• Capacity

  The cooling capacity of a 3-ton air-cooled chiller is equivalent to 36,000 BTU per hour or approximately 12,000 watts. This capacity indicates the amount of heat that the chiller can remove from a process or equipment per unit of time.

• Compressor

  3-ton air-cooled chillers typically use scroll or screw compressors as their cooling methods. The precise compressor employed can impact factors like efficiency, noise level, and maintenance needs.

• Condenser

  There are two types of condensers: axial flow and radial flow. An air-cooled condenser works by circulating ambient air around the refrigerant pipes to change the refrigerant from gas to liquid, releasing heat into the environment in the process.

• Evaporator

  The evaporator absorbs heat from the liquid or fluid before Cooling the refrigerant. Air-cooled evaporators are made to cool substances by utilizing the warmth present in the air.

• Operating temperature

  Chillers are designed to maintain specific temperatures. Depending on the ideal temperature, different industrial processes can be applied.

  A 3-ton air-cooled chiller generally has an evaporator temperature range from 20 to 50 degrees Fahrenheit (-6 to 10 degrees Celsius) and a condenser temperature range from 70 to 130 degrees Fahrenheit (21 to 54 degrees Celsius).

• Power supply

  An air-cooled chiller's operating power is generally between 5 and 10 KW.

To ensure optimal performance and longevity, 3-ton air-cooled chillers require regular maintenance. Routine maintenance not only ensures the performance of the machine but also helps to save energy consumption to reduce costs.

• Monthly external cleaning

  Use a vacuum cleaner with a soft brush to remove dust, dirt, and other foreign objects, especially in the condenser.

• Quarterly inspection of fluid levels inside the machine

  Check the machine's refrigerant and hydraulic oil for any leakage problems or the need to add to the fluid.

• Annual professional comprehensive inspection

  Invite a professional to inspect and repair the air-cooled chiller; for example, ensure the compressor is working efficiently and replace the condenser fan motor if necessary.

How to choose an air-cooled chiller

Buyers looking to invest in a 3-ton air chiller for their business application should begin by performing a critical requirement analysis. A detailed understanding of how to cool the process liquid, the medium to be used, and the target temperature will go a long way in helping to discover specific requirements.

Once the need is understood, buyers should consider the location of the chiller. If the cooling application is indoors, an air-cooled indoor chiller would be ideal. On the flip side, an air-cooled outdoor chiller would be more appropriate if the unit would be placed outdoors. This consideration will help to select a chiller that meets the installation requirements and avoid spending extra to make additional installations to enable the chiller to function.

Similarly, after deciding on the type of chiller, buyers should take note of the cooling capacity. Since industrial chillers are rated in BTUs, it is important to choose a machine that can adequately provide the required cooling.

Apart from the working components of the chiller, including the compressor, condenser, evaporator, and expansion valve, which work together to remove heat from a process or space, buyers should also consider the refrigerant used in the chiller. Different types of refrigerants are available, and their environmental impact is crucial. Buyers should choose a chiller with refrigerant characteristics that align with their sustainability goals.

The chiller's system control will determine how cool the environment or process can be. Simple on/off control may be sufficient for some applications, while others may require precise digital control. Buyers should find a chiller with the right regulatory system for their specific needs.

Also, the physical size and weight of the chiller are important considerations, as this will determine how easy it will be to move and install the chilling unit. Since the 3-ton air-cooled chiller falls within the small to medium size of chillers, it is possible to find models with casters for easy maneuverability.

Finally, after determining all these factors, the buyer should ensure that the chiller chosen is energy efficient. An energy-efficient chiller will help to reduce long-term operating costs and be in line with global goals to reduce carbon emissions.
