Oven Model UNB 500
Standard equipment
Ventilation and Control
* natural convection
* continuous adjustment of pre-heated fresh air admixture
* vent connection with restrictor flap
* microprocessor PID-temperature controller with integrated autodiagnostic system with fault indicator
* one Pt100 sensor class A in 4-wire-circuit
* integrated digital timer ( 1 min. up to 99 h 59 min) to switch off heating to stand-by mode
* digital LED- display of set and actual temperature as well as remaining process time
* resolution of display for set value and actual value 0, 5 ° C
Overtemperature protection ( double)
* in case of total breakdown of sensor, the heating is switched off at approx. 10 ° C above set value
* in case of failure of the switching element, the heating will be controlled by an additional relay approx. 10 ° C above the set temperature
* in case of a faulty sensor ( incorrect measuring values) or the total breakdown of the controller the heating is switched off at approx. 10 ° C above the max. oven temperature by the mechanical temperature limiter TB protection class 1
* for very sensitive and/ or valuable load in terms of being non-reproducable, we recommend ovens of our E- and P-class guaranteeing an even higher safety standard
