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


Intelligent program control

  • 10 programs available for temperature ramp up and dwell control.
  • 10 steps per a program and 99 hours 59 minutes per a step.
  • Stored programs are easily linkable.
  • Programs can be repeated up to 99 cycles.
  • Pre-heating and heating time are settable before program starts.

Performance

  • Temperature range.
    - RW3-35P models from -35°C to 150°C.
    - RW3-25P models from -25°C to 150°C.
  • 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

Convenience

  • Intuitive touch screen LCD controller with easy icons and logical menus.
  • Dual wait on/off timer modes. (1 min. to 99 hr. 59 min.)
  • Digital input and output control function for interlocking external devices.
  • RS-232 / USB interface for external control and data collection. 
  • 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.
  • Usage of 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.
  • Built-in casters and side handles for easy transport and installation.

Touch LCD Controller

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.
  • Temperature warning Indicator simply shows inner reservoir’s temperature by three different colors.
  • 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.
  • Splash-proof keypad.
