PDF Catalog
Compact integrated accuracy constant temperature water circulator operable both as a desktop type and integrated in a unit.
Constant temperature water circulator integrated with the cooling/heating assembly and the power control assembly and being able to precisely control constant temperature water at around room temperature. It uses a freon-free cooling system and is environmentally friendly as well as supports free power supply from AC100V to AC230V.
Features
  • This product is a circulating type and can be used as a constant bath that can cool, heat, and retain heat of your bath.
  • RS485 communication function equipped as standard allows centralized management with a PC.
  • Water cooled heat discharge system (CTW) and Air cooled type (CTA) that does not need any tap water are available.
  • Selectable from different cooling capacities and pump capacities according to the specific applications.
  • Free power supply from AC100V to 230V. Power plug or adapter is option for AC200V to 230V.
Functions
  • Fixed value operation, program operation, auto stop operation, quick auto stop operation, auto start operation, external sensor control, external communication function, alarm output, etc.
