Cooling unit PS1223CO is second generation of water-to- water cooling units designed for flashlamp-pumped lasers. Microcontroller operated PS1223CO has better performance than PS1222CO while maintaining full backward compatibility.

PID controller smoothly regulates water flow thru heat exchanger maintaining high stability of output temperature in a wide range of removed heat (Fig. 1). 4 digital thermometers measure temperature of coolant at output, return, tank and water supply. Coolant flow, pressure, tank water level and conductivity are also measured. Using this data microcontroller stabilizes output temperature, estimates removed heat, generates early warnings and errors. All data can be accessed by any of interface: USB, Ethernet or optional RS232, RS485, CAN. Test and adjustment utility program for Windows is included (for use with USB interface).

Coolant flow and output pressure can be adjusted manually using bypass valve, located inside unit and accessible when front panel is open (Fig. 2).

Maximum heat removal capability of the PS1223CO depends on temperature difference between coolant output temperature and supply water temperature (Fig. 3).
