Refrigerated & Heating Bath Circulators(General)

Rapid heating and cooling throughout the entire temperature range.

Model Name : RW3-0525/1025/2025/3025
RW3-0535/1035/2035/3035


Performance

  • Temperature range.
    - RW3-35 models from -35℃ to 150℃.
    - RW3-25 models from -25℃ to 150℃.
  • Microprocessor PID 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)

Pump Step 1 2 3 4 5
Max. pressure (psi) 0.5 1.1 2.4 4.9 5.9
Max. flow rate (L/min) 5.6 8.0 12.8 18.8 28.0

※ Bath fluid: water at the normal temperature.

Convenience

  • Bright VFD display with quick adjustable dial knob. (0.1℃resolution)
  • Dual wait on/off timer modes. (1 min. to 99 hr. 59 min.)
  • Convenient memory function of up to three frequently set temperature.
  • Corrosion-resistant, leak-proof, round-cornered, and easy-to-clean stainless steel bath with easy access drain valve.
  • Detachable condenser air-filter for easy maintenance of refrigerating efficiency.
  • CFC-free refrigerant (R-507, R-404A) and a double service valve for leakage prevention.
  • Quick-release front grill for easy cleaning of the condenser.
  • RS-232 / USB interface for external control and data collection. 
  • Side handles enables convenience handling and transport
  • Easy maintenance of condenser by removable gridded vent

  • Condenser air-filter for refrigerating efficiency

Safety

  • Isolated design of agitator, heater, and sensor by a baffle plate to minimize the turbulence in the bath fluid and also to protect users and samples against direct contact.
  • Complete safety protection system with warning alarms.
    - Low fluid level and dry-running, over-temperature, over-current.
  • Keypad lock function prevents accidental changes during operation.
