Jeio Tech Refrigerating & Heating Bath Circulators (RW3 Series)

Performance : 

  • Temperature range (RW3-35 models from -35°C to 150°C and RW3-25 models from -25°C to 150°C).
  • Optimum refrigeration system by microprocessor PID control. Energy efficient refrigeration operation is available within full range of temperature control.
  • Three point temperature calibration/automatic tuning/automatic run.
  • Suitable for both internal and external bath environments due to reduced turbulence by using five-speed adjustable pump and built-in cooling coil (1 to 3 steps of the pump for internal circulation and 4 to 5 steps for external circulation).
