Refrigerated & Heating Bath Circulators(Programmable)
Newly developed bath circulator with the Intelligent programmable controller.
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.
- Monitor via mobile app anytime, anywhere with LC Connected (mobile monitoring system) connection. (when purchased LC GreenBox)
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.
