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)

--digital LED-display of set and actual temperature as well as remaining process time

--resolution of display for set value 0,5 Degree Celcius for actual value 0,5 Degree Celcius

--incl.work calibration certificate for +160 Degree Celcius

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 class 1

-- for very sensitive and/or valuable load in terms of being non-reproducable, we do recommend ovens of our E- and P-class guaranteeing an even higher safety standard
