Schedule a consultationProduct Description
Rapid heating and cooling throughout the entire temperature range.
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
- Monitor via mobile app anytime, anywhere with LC Connected (mobile monitoring system) connection. (when purchased LC GreenBox)
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.

※ Technical data (according to DIN 12876)
※ In case using silicon oil, you need to exchange other material tube (inlet and out late part), such as copper tube, a teflon tube instead of a silicon tube in fitting.
1) Technical data according to DIN 12876. (bath fluid : ethanol at -10℃)
2) The cooling capacity is measured under 230V / 60Hz electrical condition.
