PDF Catalog
  • Water cooling heat dissipation system (CTW type) and air cooling heat dissipation system (CTA type) are available.
  • 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 Freon-free cooling system.
  • The RS485 communication function is provided as standard and can be centrally managed from a PC.
  • Suitable power supply ranges AC100V or 200V.
