COOLING UNIT PS1222COis designed for flashlamp-pumped lasers and provides effective heat removal and high stability of laser rod temperature. This enables long term operation of your laser at maximum efficiency. Unit is assembled in 19" chase and may be used completing the powering group of laser systems. Also it can be mounted into the 19'' rack.

Operationof cooling unit is based on water-to-water heat exchange. Deionised or distilled water of 1-20 µS/cm conductivity is used in laser loop of cooling unit.

Temperature stabilityof coolant is maintained by electronic circuit. Stabilization temperature is set by 10-turn potentiometer within 17-35°C (another range is available according to customers requests).

Indicationof coolant and set temperature, coolant level (low/high), overheat and pressure absence in laser loop is provided on front panel of cooling unit. Purity low LED indicate condition of deonisation cartridge.

Blocking and protectioncircuitry in case of overheating, pressure absence or coolant level is out of high/low limits sends interrupt signal to interlock connector to which protection circuitry of laser powering might be connected. Coolant pump will be stopped in case of pressure absence or coolant level is out of limits.

Deionisation andfiltrationof coolant eliminates a build up on the flashlamp, reduces servicing need and allows laser operation at maximum efficiency in day-to-day use.
