Universal Oven Memmert UN

Models UN / UNE / UNP with natural air circulation.
Models UF / UFE / UFP with forced air circulation.
From + 30 up to + 220 °C (BASIC).
From + 30 up to + 250 °C (EXCELLENT and PERFECT) - against extra charge up to 300 °C.

• Homogeneous uniformity by large-area heating on four sides.
• According to DIN 12880:2007-05.
• Standard ovens are safety-approved and bear the test marks of GS, VDE, EMV, CE and GOST.

BASIC:

• With electronic PID-controller.
• 1 Pt100 sensor DIN Class A in 4-wire-circuit.
• Integrated digital timer from 1 min to 99:59 h.
• Digital display of setpoint and actual temperature as well as residual running time.
• Double overtemperature protection by additional relay, following the setpoint with 10 °C difference and temperature limiter TB class 1.

EXCELLENT:

• PID-microprocessor-control with fuzzy-support.
• Fan to be switched on and off resp. adjustable in 10 % steps (ovens with forced air circulation).
• 2 Pt100 sensors DIN-class A in 4-wire-circuit, for monitoring each other.
• Real-time / weekly programmer timer.
• Timer with residual running time for one profile with 4 segments each from 1 min up to 999 h.
• 'Loop'-function to repeat profile (1 to 99 times or endless).
• Digital display of all parameters, such as temperature, weekday, time, fan speed (ovens with fan only), programme status and set-up values.
• Integrated GLP-conforming long-term documentation via ring memory as datalogger.
• Triple overtemperature protection: Additional relay switches off heating about 10 °C above setpoint value. Digital electronic overtemperature controller TWW, protection class 3.1. Optional: adjustable temperature-limiter. Mechanical temperature limiter TB protection class 1 to switch off heating at about 10 °C above max. oven temperature.

PERFECT:

• Adaptive, fuzzy-supported multifunctional digital PID-microprocessor controller.
• Adjustment of pre-heated fresh air by air flap through process controller in 10 % steps for each segment individually.
• Fan speed adjustable in 10 % for each segment individually (only for ovens with forced air circulation).
• 2 Pt100 sensors DIN Class A in 4-wire circuit for monitoring each other.

• Multifunctional programming via menu on 8-digit alphanumeric display.
• Integrated GLP-conforming long-term documentation via ring memory as datalogger.
• MEMory Card XL for programming and documentation of up to 40 ramps.
• Multiple overtemperature protection: With audible and visible alarm. Electronic overtemperature controller TWW protection class 3.1 or adjustable temperature limiter TWB class 2 to be selected in set-up by customer. ASF Automatic Safety Function for over- and undertemperature following the setpoint value at a freely selectable tolerance range. Mechanical temperature limiter TB class 1.
