Liquid-Liquid Systems (LL)
Liquid-Liquid assemblies are used to cool or heat liquids (or gases) passing through
a heat sink. Heat is dissipated to a liquid on the warm side.
The liquid circuit is normally of a recirculating type with a pump and a liquid-to-air
heat exchanger to remove the heat into the ambient air.
By using an efficient heat exchanger and one or more LL-assemblies, a powerful yet
compact system is created.
The liquid heat sinks are made of anodized aluminum. In the event that your application
calls for another material in contact with your media, use a DL assembly and mount your
own liquid heat sink using that material. To improve heat transfer, turbulators are
inserted into the liquid channels.
The standard assemblies are optimized for high cooling capacity and efficiency rather
than maximum delta T.
Typical applications are medical and analytical equipments, cooling/heating of process
fluids.

Specifications apply to warm side Liquid temperature 32°C and nominal Voltage. Tolerances ±10%
Ex =Example: At 40°C inlet liquid temperature on warm side and
2°C outlet temperature on cold side(delta T = 30°C) the LL-210-24-00 (curve B)
cools by 32% of its maximum effect, which gives Pc = 208 x 0.32 = 67 W (±10%)
