This waterblock will accommodate;

  • Any object to be cooled up to 65 x 65mm.
  • 2, 3, or 4 TECs or TEGs up to 30 x 30mm.

CNC machined from solid 99.9% pure copper.

This waterblock has been tested with a heat load of up to 1200 watts. All indications showed that it could handle higher loads.

Standard O-ring material is Buna-N which is capable of fluid temperatures from -29 to +120 C. Alternative o-ring materials are available as an option. Please contact us if you need other materials.
