For internal and external temperature applications - compact and powerful. The HighTech series of microprocessor controlled (PID) heating circulators integrate features valued by those with more demanding applications.

The circulators provide higher operating temperatures and better stabilities than the Economy and TopTech series. All HighTech circulators are capable of monitoring an external system directly with an Pt 100 temperature sensor. Integrated RS232 interface. Safety class 3.

The HighTech series offers additionally:
  • ICC = Intelligent Cascade Control
  • Optimum temperature stability with varying systems achieved by the self-tuning controller, adjustable PID control parameters
  • VFD_comfort display, resolution to 0.01°C
  • External measurement and control with Pt 100 sensor, connections for programmer and temperature recorder
  • RS232 interface
  • LCD display (HL and SL models only) for convenient user-guidance, analog/digital setpoint input; display resolution: 0.01 up to 99.99°C
  • Integrated programmer with realtime clock
