Memmert UN450plus Universal Cabinet, 449 litres, TwinDISPLAY, natural convection, 300 °C

Programmable large-capacity temperature control without turbulence: Memmert UN450plus

The Memmert UN450plus universal cabinet combines a generous internal capacity of 449 litres with maximum process control and gentle heat transfer. Thanks to natural convection (without a fan), this cabinet heats large batches or bulky samples completely free of turbulence. It is the premium solution for laboratories and industry when fine powders, light granules or sensitive components need to be dried or aged, which could be stirred up or damaged by an air flow.

TwinDISPLAY: Intuitive programming for demanding processes

As a model in the “Plus” series, the UN450plus offers full programmability. Complex temperature ramps and process cycles can be created with ease via the intuitive TwinDISPLAY, featuring two high-resolution TFT touchscreens. The electronically controlled exhaust air flap regulates the fresh air supply precisely in 10% increments. A particular highlight for large interior spaces is the HeatBALANCE function: this allows you to adjust the heating output specifically between the upper and lower sections of the cabinet, for example to perfectly balance asymmetrical loads.

Redundant safety and comprehensive documentation

Two independently operating Pt100 sensors (DIN Class A) ensure maximum process reliability and validatability (GMP/GLP). If one sensor fails, the second seamlessly takes over temperature control. The integrated AutoSAFETY system reliably protects your valuable batches through visual and audible alarms, as well as automatic heating shutdown in the event of deviations. All process data is stored in the internal data logger and can be read out via USB or Ethernet using the supplied AtmoCONTROL software.
