LS Dual Tempera-ture Series
Technical Characteristics
The unit provides water the temperature of which is close to the ambient
temperature for lens cooling while providing stable and accurate temperature water to the circuit. It eliminates solves the trouble that the lens may be broken by frosting as a result of low temperature water cooling.
