The Memmert UN55PA Natural Convection Paraffin Oven 53L, 115V, offers a spacious 53-liter (1.9 cu. ft.) chamber ideal for precise paraffin applications and reliable temperature control. Operating within a temperature range of +20°C to +80°C, this oven features natural convection to provide even heat distribution without the need for forced airflow. Its highly accurate 0.1°C temperature setting resolution is maintained by dual Pt100 sensors, ensuring consistent performance with integrated fault tolerance for added security. The adaptive PID-microprocessor controller with TwinDISPLAY and dual high-definition TFT displays allows for intuitive control, precise adjustments, and continuous performance monitoring.
This oven is equipped with advanced safety features, including the AutoSAFETY system, which offers automatic over- and undertemperature protection with visual and acoustic alarms to prevent overheating. The robust stainless steel interior is easy to clean and reinforced for durability, while the fully insulated stainless steel door with a 2-point locking system ensures an airtight seal. For ease of programming and monitoring, the AtmoCONTROL software is included, allowing users to manage settings and transfer programs via USB or Ethernet. The UN55PA is built for efficiency, reliability, and the highest standards of paraffin application.
