The Lindberg/Blue M ESP-400C-5 is a mechanical convection oven designed for thermal processing applications requiring precise temperature control and chamber uniformity. It operates from 15°C above ambient to 260°C (500°F) and accommodates loads up to 100 lbs. distributed across seven adjustable shelf positions. The oven employs horizontal one-pass airflow with a centrifugal blower delivering 375 CFM at 0.5″ WC, enabling rapid thermal cycling and efficient exhaust of non-hazardous vapors. Built-in Blue M Eterna nichrome heating elements and dual temperature control architecture—primary RKC RF100 or Partlow controller paired with FM-approved over-temperature protection—ensure repeatable performance in laboratory and production environments.
