Air cooled condensing units are a critical component in refrigeration and air conditioning systems, designed to condense a refrigerant from a gaseous state to liquid by cooling it. Unlike water-cooled condensing units that require a water source to remove heat, air cooled units use ambient air for this purpose, making them highly versatile and suitable for a wide range of applications where water resources are scarce or water use is to be minimised.
Our air-cooled condensing units are engineered with precision, featuring advanced components that ensure superior energy efficiency. By optimising heat transfer and reducing operational costs, our units support your sustainability goals without compromising on cooling performance. Whether for commercial refrigeration, or industrial cooling our expert team will collaborate with you to design and install the perfect cooling solution that’s right for you.
Here you’ll find answers to common questions about industrial process chillers
A refrigeration system removes heat from a space or process and rejects it elsewhere using a refrigerant cycle (compression, condensation, expansion, evaporation). Compressor, condenser, expansion device, evaporator, refrigerant, and control system
Common refrigerants include R410A, R454, and R32, along with newer low-GWP refrigerants such as R1234ze and R290. Refrigerant selection depends on the application, operating temperatures, system design, and current environmental regulations.
Poor cooling performance can be caused by refrigerant leaks, dirty heat exchangers, faulty expansion valves, compressor issues, or inadequate airflow or water flow. A system assessment is required to identify the root cause and restore reliable operation.
Service intervals typically range from every 6 to 12 months, depending on system usage, operating environment, and criticality. Higher-duty or critical systems may require more frequent inspection and maintenance.
A chiller removes heat from a circulating liquid, typically water or glycol, and supplies chilled fluid for air conditioning systems or industrial process cooling.
Air-cooled chillers reject heat directly to ambient air using condenser coils and fans.
Water-cooled chillers transfer heat to water, which then rejects it via a cooling tower or an air-blast cooler.
Chillers are used across commercial and industrial sectors including offices, hospitals, data centres, food and drink processing, pharmaceuticals, plastics manufacturing, and chemical processing.
COP (Coefficient of Performance) and EER (Energy Efficiency Ratio) are indicators of chiller efficiency. Higher values indicate greater efficiency for cooling output.
Air-cooled chillers offer lower installation costs, no cooling-tower requirement, reduced water consumption, and simpler maintenance. However, they can be less efficient in high temperatures, produce more noise, and require larger outdoor space.
Air-cooled chillers are usually installed outdoors or in open areas with sufficient airflow to ensure stable operation.
Water-cooled chillers typically deliver higher efficiency, longer service life, and better performance in high ambient conditions. They do, however, involve higher initial costs, more complex installation, and increased maintenance due to cooling towers or air blast systems.
