When it comes to industrial cooling solutions, businesses often have to choose between water-cooled and air-cooled water chillers. For those with limited access to water, an air-cooled chiller emerges as an efficient and cost-effective alternative for various process cooling applications. These chillers are not only high-quality but also easy to maintain, thanks to their compact size and built-in hydronic module.
Wondering what makes air-cooled chillers a good choice? This guide outlines the key features to look for when evaluating this cooling solution for your specific needs.
One of the reasons to choose air-cooled chillers is the absence of cooling towers. As such, they are easier to install and set up, with only reliable pipe connections and power sources required to get started. Moreover, their working ambient temperature can be configured to -25 to 60 degrees Celsius, with coolant temperatures from -30 to 30 degrees Celsius and precise control. This way, the chillers can be used across different applications in various industries.
High-quality air-cooled chillers are designed based on the latest technological advancements and innovations in the process cooling industry. Reputable manufacturers rely on the knowledge, skills, and capabilities of their design team to ensure a solid external structure for a stronger foundation. Plus, all components go through repeated trials and strict calculations before integrating them into the air-cooled water chiller.
Newer air-cooled chillers are more efficient and safer to use, especially when they come with overheating protection for the discharge temperature, high-low pressure, motor overload, and compressor motor. In addition, the carefully researched and designed refrigeration system helps reduce failure rates and the need for maintenance. This way, the chiller can provide a longer service life and increased customer satisfaction.
Not all air-cooled chillers are efficient for all applications. However, some have features that make them more reliable than others. Here are considerations when comparing products:
· Advanced scroll compressors
Choose air-cooled chillers with high-end hermetic scroll compressors from brands like Copeland and Danfoss. These reputable compressor manufacturers are known for their highly efficient, long-lasting parts.
· Smart microprocessor controller
Advanced microprocessors provide precise temperature control and comprehensive monitoring, with an audible alarm and a text display for relaying alerts and critical information. Moreover, they support popular communication protocols like MODBUS and RS-485.
· European Schneider Electric parts
The breaker, AC contactor, and thermal relay are critical components in air-cooled chillers. So, they must be of high standard for a stable performance and a longer service life.
· Built-in hydronic module
Integrating the large-flow circulation pump and buffer tank simplifies installation and operation. However, make sure the outlet and inlet water bypass valves allow the water pressure to be adjusted as needed. In addition, consider an air-cooled water chiller with a sight glass for the water tank so it’s easy to check the water quality.
· High-quality heat-exchanging parts
Look for a generously sized aluminum fin condenser coated with epoxy resin to minimize the risk of ambient corrosion. Moreover, ensure the immersion coil evaporator is a standard feature to stabilize performance and simplify cleaning.
Air-cooled chillers can be configured with the following components to optimize their performance in specific applications:
· Expansion tank for stabilizing water circuit pressure
· Closed-circuit version to suit an external chilled water reservoir
· Medical- or food-grade stainless steel water circuit
· Remote control panel
· Dual water circuits
· R134a refrigerant to suit up to 60 degrees Celsius of ambient temperatures
· PLC control system with a color touchscreen and support for PROFINET and HMI
· Heat recovery module
