Air Cooled Industrial Chillers for Data Centres by Summit Matsu Chilling Systems

• The water cooling for data centres is done by a series of chillers which remove heat by a refrigeration system and discharge waste hot air
• The chilled water is then pumped through close control air handling units for server room cooling and plumbed under floor direct rack cooling
• Some rack cooling systems include a chiller water correction for each cabinet or enclosure while others have a hot row/cold row configuration, as a single cooling rack in line for a number of server racks
• Air-cooled chiller from Summit Matsu Chilling systems are supplied in a modular fashion for a n+1 solution which allows for redundancy and can be integrated with a chiller tank and pump unit as a package

Chiller Configuration

• Because data centre infrastructure must often be retro-fitted to existing buildings the modular chiller configuration allows installation in limited space. Environments and air discharge can be either horizontal or vertical
• Multiple refrigeration systems can be built into each chiller for added redundancy and can be stages on a lead-lag arrangement to spread equal run hours across all compressors and chillers

Choosing an Air Cooled Industrial Chiller

• Compressors are used for high efficiency and PLC (Programmable Logic Controllers) can link back to virtually any control system in the data centre
• The chiller control system features diagnostic safety controls to protect the refrigeration system from damage in the event of over temperature
• Because rack cooling and equipment cooling can operate with higher water temperature than air conditioning systems, Summit Matsu Chilling systems supply chillers that are optimised for performance at a higher temperature which increases the energy efficiency of the water cooling system
• Naturally all Summit Matsu Chilling Systems chillers are built for Australian conditions
• The regular chiller controls can protect the machine from multiple fault events including loss of water flow, air flow loss of phase or incorrect air flow, motor protection for temperature and correct refrigeration gas pressure safeties
• Summit Matsu Chilling Systems also offer a "whole of life" chiller plant solution including extended warranty and service
