Cooling Water Circulator (Externally Opened Circulation, Peltier Cooling) (CTW812)
Water cooling heat dissipation system (CTW type) and air cooling heat dissipation system (CTA type) are available.
Features of Cooling Water Circulator (Externally Opened Circulation, Peltier Cooling) (CTW812)
- Integrated type (CTW402 / 802, CTA402 / 802) and Separated type (CTW402S / 802S, CTA402S / 802S) are selectable.
- External open constant temperature water circulator with separate cooling/heating assembly and power control assembly enables to control the constant temperature water precisely. It uses a Freonfree cooling system.
- The RS485 communication function is provided as standard and can be centrally managed from a PC.
