※ Technical data (according to DIN 12876)

※ In case using silicon oil, you need to exchange other material tube (inlet and out late part), such as copper tube, a teflon tube instead of a silicon tube in fitting.

1) Technical data according to DIN 12876. (bath fluid : ethanol at -10℃)
2) The cooling capacity is measured under 230V / 60Hz electrical condition.
