One compressor is digital scroll for maximum efficiency and stage for lower load conditions.
All told, air cooled chillers can provide simple and effective solutions for many process cooling needs. Air cooled chillers are among the most commonly used refrigeration systems for commercial and industrial facilities. They work by absorbing heat from process water and then transferring this heat, meaning that they should be used in areas where heat discharge is not a serious issue. Like water cooled chillers, they have a compressor, condenser, evaporator, and expansion valve that work to chill water and absorb heat. As opposed to water cooled chillers, they use air to fuel condenser cooling. Most if not all outdoor applications for chillers will use air cooled chillers as excess heat is released into the ambient air.
Any production of excess heat with an air-cooled chiller can actually be beneficial during the cold winter months when the heat could be used to warm the plant and reduce your monthly energy bills. The internal pressure relief valve allows you to limit the maximum fluid pressure to meet the application requirements. Provides analog and digital communication for remote operation, monitoring and data logging. Includes a remote sensor port which allows for remote temperature control of an application when used with a remote sensor . This frees crucial backup power for other mission critical operations while maintaining sensitive climate controlled areas. In most cases the chiller motor is the largest draw on electricity in the entire building. Single speed drives are on or off and cannot adjust for the difference in load the system is running under.
Space is also a consideration of importance in some applications. Meaning, the location where you intend to install the physical unit. Air-cooled chillers tend to utilize open space, such as a parking lot, roof or ground level area. Water-cooled chillers need a large physical area for installation, including a mechanical room and a place for cooling towers. As opposed to air-cooled units, water-cooled chillers use water from an external cooling tower to reject heat from the condenser. They are commonly used in large industrial applications, including manufacturing and food processing. An air-cooled chiller are systems that absorb heat from the water before transferring the heat outside of the system and into the air surrounding the chiller unit.
In contrast a variable speed drive saves energy as it can adjust the speed to match the load. This saves a significant amount of energy in your chiller system. In addition variable speed allows the system to ramp up more smoothly in the case it is turned on in an emergency situation. The simple fact is that the chiller makes up for a significant portion of your electricity usage, even at peak performance. If you’ve got maintenance issues it can easily use an extra 10%, which hurts the bottom line. While technology has improved to remotely monitor chillers and technology has produced more durable and efficient parts, maintenance is still key. Lasers are fast becoming a more common element of production, and one that produces a lot of heat.
Where you can witness proof of its performance in our Live-Load Proving Lab. The evaporator is a heat exchanger which allows the heat energy to migrate from the water stream into the refrigerant gas. During the state change of the remaining liquid to gas, the refrigerant can absorb large amounts of heat without changing temperature. Water or liquid chillers can be liquid-cooled, air-cooled, or evaporatively cooled. Water or liquid-cooled systems can provide efficiency and environmental impact advantages over air-cooled systems. The expansion valve meters the flow of refrigerant around the system. DHC can automatically lower the indoor unit coil temperatures to quickly remove any humidity increase. When humidity is within acceptable limits, the system will dynamically reconfigure itself to the most efficient possible operating parameters allowing the chiller to run well above its rated efficiency.

Run and tested before shipping, and sold with money back guarantee. Arrived at KIG in July 2015 was this nice 2006 Advantage Air Cooled Chiller. This unit has its own process pump, an internal reservoir, and a brazed/plate heat exchanger. eNoise Control has been involved with several outdoor HVAC chiller noise applications. Air cooled chillers with rotary screw compressors present the largest challenge for adequate noise control because of the multiple sound sources and the tonal quality of the noise. Below are some actual case histories of Unger’s involvement with outdoor environmental noise control dealing with air cooled chillers. Water-cooled chillers feature a water-cooled condenser connected with a cooling tower.
While this does fix the problem it is a temporary solution as the chiller must work harder for the same effect. Motivair’s Heat Dissipation Unit™ is an active heat exchanger that converts liquid-cooled computer systems to air-cooled by rejecting heat to the server room. Motivair’s Liquid Cooling Technology allows you to leverage increased processing power while using less energy and space than traditional air-cooled systems.

Motivair Water-Cooled Chillers are ideal for clients looking for a simple, compact, and reliable product to provide maximum equipment uptime and lowest TCO. A common step of many types of beverage production is cooking, mixing, and pasteurizing. Whether its soda, beer, milk, or other drinks the beverage industry relies on chillers to remove heat produced by these processes.
As water has a higher capacity, using water-cooled chillers to remove heat is traditionally more efficient than using air-cooled chillers. Laser chiller can precisely control the temperature required by laser equipment, thus ensuring the constant normal operation of laser equipment, this is Air Cooled Chiller for Cooling Your Laser Machine. Air-cooled chillers will remove the heat in the process usually requires an air-cooled chiller that is installed outside the workshop. In industrial applications, air-cooled chillers are commonly used in the production process or laboratory equipment. Insufficient pressure and flow will not produce enough cooling and even worse, more heat will be generated due to the high cooling load. The heat of the air-cooled chiller released by the refrigerant in the condenser is carried away by air.
These are ideal for customers with mold related heat issues and water quality issues. In the evaporator, chilled water is created when unwanted heat is drawn into the refrigerant before it is fed into the condenser. The differences between air conditioning and chillers can be subtle at the cooling process level, but very different in applied usage. Chiller operational efficiency will greatly impact your building operating costs. Ongoing routine maintenance represents the minimum from the perspective of facility management. Predictive maintenance and optimization of the chiller system requires real-time operational data. Artificial Intelligence continues to advance in everyday practical applications. Machinery such as chiller systems will benefit from AI algorithms that can detect potential failures before they occur. Predictive maintenance leverages the collection and analysis of chiller system operational data to determine when maintenance actions should be taken prior to catastrophic failure.
The Psychrologix™ chiller control option also adds a wide range of programmable and automated features in addition to DHC and can manage up to three chillers. A refrigerant brings unwanted heat from the evaporator and passes through the condenser. There is another loop connected to the condenser- the condenser water loop, which is between the cooling tower and the condenser. After entering the condenser at about 27°C (80.6°F), the water leaves at 32°C (89.6°F) and heads to the cooling tower. Note that at no time do the refrigerant and the condenser contact directly. The condenser water, with the unwanted heat, goes to the cooling tower for further heat rejection.
