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

※ 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.
