Water Baths WNB / WNE / WPE and Oil Baths ONE

Water Baths:
Working temperatue range WNB / WNE: at least 5 °C above ambient to + 95 °C and additional boiling stage; boiling stage on model WPE only with pump switched off.
  • Setting temperature range WNB / WNE from + 10 up to + 95 °C and additional boiling mode WPE 45 without boiling mode.
  • Temperature deviation temporal / spatial max. ± 0.25 °C / ± 0.1 °C
  • Housing made of textured st. steel 1.4301.
  • Deep-drawn, hermetically welded st. steel working chamber 1.4301 (ASTM 304).
  • Resolution of display for setpoint and actual values: 0.1 °C.
  • Mains supply: 230 V, 50 / 60 Hz.
  • Standard units bear the CE-test marks and EAC.

Water Baths WNB:
  • Electronic microprocessor PID-controller with integrated autodiagnostic system with fault indicator.
  • Solid state switching unit.
  • 1 Pt 100 sensor DIN class A in 4-wire-circuit.
  • Integrated digital timer from 1 min to 99:59 h.
  • ON (continuous operation) / WAIT (delayed on for continuous and limited timed operation) / HOLD.
  • Digital display of setpoint and actual temperature as well as residual running time.
  • LEDs for indication of programme status.
  • Double overtemperature protection: In case of overtemperature due to failure the heating is switched off at approx. 10 °C above setpoint temperature. Mechanical temperature limiter TB protection class 1 to switch off heating at approx. 30 °C above max. bath temperature.

Water Baths WNE:
  • PID-microprocessor-control with fuzzy-support with integrated autodiagnostic system with fault indication.
  • Solid state switching unit.
  • 2 Pt 100 sensors DIN-class A in 4-wire-circuit, for monitoring each other and taking over the performance at the same temperature value.
  • Digital timer from 1 min to 999 h.
  • ON (continuous operation) / WAIT (delayed on) / HOLD or HOLD setpoint dependent with guaranteed holding time.
  • Digital display of temperature, time and alarm values.
  • Calibration facility on controller.
  • Audible and visible alarm at programme end and as input acknowledgement as well as in case of low liquid level; heating is switched off automatically.
  • Triple overtemperature protection: in case of overtemperature due to failure the heating is switched off at approx. 10 °C above setpoint temperature. Independently working, electronic temperature controller TWW protection class 3.1 or adjustable temperature limiter TWB protection class 2 to be selected by customer in set-up. Resolution of display / setting accuracy: 0.1 up to 99.9 °C, 1 °C from 100 °C. Mechanical temperature limiter TB class 1 to switch off heating about 30 °C above max. bath temperature.

Water Baths WPE:
As WNE but with additional circulation pump, boiling stage (only with pump switched off). Working temperature range at least 15 °C above ambient to +95 °C.

Oil Baths ONE:
Working temperature range at least 15 °C above ambient to + 200 °C. Setting temperature range from + 20 to + 200 °C are available in the same sizes as water baths. Features similar to WNE, however, instead of overtemperature controller TWW the oil baths are provided with adjustable temperature limiter TWB class 2 (it is not possible to choose between TWW and TWB).
  • Standard units bear the CE-test marks and EAC.
