Optimizing the selection of a re-circulating chiller
A re-circulating chiller is used to supply a steady flow of temperature-controlled fluid to an application. The fluid temperature coming from the chiller could be used to cool, maintain or even increase the temperature of the application. Five criteria must be defined in order to select the correct

When is it necessary to add glycol in your coolant?
Lytron recommends using a 30/70 glycol-water mixture with its recirculating chillers whenever the coolant temperature set point is below 10°C (48°F). The glycol lowers the freezing point of the mixture *(Figure 1). In a recirculating chiller, the liquid coolant (usually water) flows through

Liquid Cooling a Laser for System Optimization
available recirculating chillers provide convenient cooling for a laser system. A compressor-based recirculating chiller's coolant temperature can be set to between -5.0°C and 35.0°C and maintain ±0.1°C temperature stability, ensuring that the laser system is operating at the optimal wavelength

Preventing Corrosion in Cooling Systems
Water and water/glycol solutions are common heat transfer fluids used in cooling systems and recirculating chillers. Although the fluids are the lifeblood for your heat transfer applications, they can also cause corrosion within your systems. This corrosion can result in a reduction in system

Positive Displacement Pump and Turbine Pump Attributes to Consider for Liquid-Based Temperature Control (.pdf)
Rotary vane Positive Displacement (PD) pumps may be the most commonly used pumps in re-circulating chillers today. Performance and low cost have made them the favored pumps for a variety of applications. Turbine (TU) pumps are also used in re-circulating chillers, however, due to their higher

The Best Heat Transfer Fluids for Liquid Cooling
5.0. Therefore, when using water that is virtually pure, it is necessary to use a corrosion inhibitor. When using deionized water in a recirculating chiller, special high purity plumbing is needed. The fittings should be nickel-plated and the evaporators should be nickel-brazed. When using deionized
