The Lindberg/Blue GO1330A-1 is a 3 cu ft gravity convection oven engineered for laboratory and industrial heating applications requiring precise temperature control without forced air circulation. Operating from ambient +40°C to 260°C, the unit delivers 3% temperature uniformity at 100°C and reaches 260°C in 106 minutes. Natural gravity airflow through perforated stainless steel shelves eliminates convection-induced disturbance, making it ideal for processes involving powders or lightweight materials. The oven features a stainless steel interior with double-wall heavy gauge steel construction and fiberglass insulation for thermal efficiency. Long-life, low-watt density heating elements operate at 1300W (120V AC, 50/60 Hz) with integrated over-temperature protection. Temperature regulation is managed by a Eurotherm 2132 PID controller with LED display, delivering stable setpoint control. A door lock mechanism and built-in safety interlocks complete the design. Interior dimensions measure 18.5 × 16 × 17.5 in; exterior footprint is 25 × 22.5 × 37 in. All units are tested and verified operational.

– Key Features
• Gravity convection airflow via perforated stainless steel shelves eliminates forced-air disruption
• Eurotherm 2132 PID temperature controller with LED interface and “straight line” control stability
• Stainless steel corrosion-resistant interior; double-wall heavy gauge steel exterior
• Fiberglass insulation and enclosed, protected heating elements
• Over-temperature protection (OTP) and door lock safety mechanism
• Included power cord; fuse protection rated not to exceed 125% of oven rating
– Typical Applications
• Heat treating and annealing operations on powders and lightweight materials
