Liquid Power Cooling

ETM has developed a line of liquid cooling subsystems ranging in capacity from 3 kW to over 200 kW, providing coolant flow from 3 GPM to 60 GPM (10 liters per minute to 230 liters per minute). Heat removal is accomplished with liquid cooling mediums such as low conductivity deionized (DI) water, Coolanol, PAO, and Glycol mixtures.

In addition to the basic job of removing heat from high-power electronics, ETM's heat exchangers are tailored to meet additional requirements driven by the customers' applications, such as:

Closed-loop coolant temperature control
Redundancy and on-line repair
Nitrogen blanketing
Active control of resistivity
Pump speed control to set outlet pressure
Packaging for outdoor or mobile use
Extended operating temperature ranges
Full-flow filtration
Coolant preheating
Precision temperature and flow monitoring
Economizer coils to eliminate dependence on mechanical refrigeration in cool weather

ETM liquid cooling subsystems use the following technologies:

Liquid-to-air
Liquid-to-liquid
Active Refrigeration
