PRODUCT SERIES - RACK MOUNTED CHILLERS

Traditional cooling systems can take up precious space in laboratories and data centers. Rack mounted chillers are cooling systems designed to fit into standard electrical housings, ideal for a reduced footprint. However, rack mounted chillers are not always mounted into electrical housing. They can be mounted into any electrical frame, such as a test rig.

 How Do Rack Mounted Chillers Work? 

The cooling system within a rack mounted chiller consists of a compressor, a condenser, an expansion valve, and an evaporator. 

Heat is taken away from the application within the heat transfer fluid to the evaporator. Here the refrigerant flows alongside the heat transfer fluid absorbing the unwanted heat. The refrigerant then passes through the compressor where it is compressed and cooled. Following this, refrigerant passes through the expansion valve where it expands and cools further. This cycle continues until the desired temperature within the heat transfer fluid has been reached. 

The cooled heat transfer fluid is then taken to a tank where it will be pumped back to the application to continue the cycle. Rack mounted chillers use a refrigeration cycle to remove unwanted heat from heat transfer fluids. The heat transfer fluid may be water, glycol (ethylene glycol or propylene glycol) or oil.

 ATC 19" Rack Mounted Chillers 

Applied Thermal Control manufacture rack mounted chillers designed to fit within standard electrical housings with a minimum depth of 600mm. Mounting a chiller within existing electrical racking reduces the loss of valuable floorspace, making no addition to the existing footprint of the system.

This is particularly beneficial for system integration. As technology advances, components become smaller, allowing for cooling systems to be integrated into existing racking as equipment is refurbished and modernized.

The R-Series from Applied Thermal Control ranges from 500W to 2kW in cooling capacity, delivered in a compact and reliable design. With powerful cooling outputs and coolant flow rates, the R-series is a versatile range, suited to a range of applications. The use of ATC 19” rack mounted chillers is particularly beneficial where 19” racks are already in situ and have space to accommodate a chiller. It is important to note that the R-Series of Rack Mounted Chillers provide a supply of heat transfer fluids at constant pressure, in order to remove unwanted heat from an associated process and should not be confused with systems designed to provide chilled air to cool the internal air temperature of housing.

The R-Series is primarily an air-cooled refrigeration system, although water cooled condensers are available as an option. All chillers within the R-Series have a stainless-steel reservoir, offering optimal thermal buffering, and a stainless-steel evaporator, ensuring corrosion free operation. Both ‘over
temperature’ and ‘low liquid level’ signals are fitted as standard, making it easy to carry out visual checks. Other standard features include: 

 Typical Applications: 

• RF signal generations
• Electrical components
• X-ray sources
• Optical devices
• 3D printing
• Ozone disinfecting
• Older electro-microscopes
