OF3-45 Large Forced Convection Oven, Solid Door, 450L

OF3-45 Large Forced Convection Oven, Solid Door, 450L

The OF3-45 is a high-performance, large-capacity forced convection oven engineered for precision, safety, and ease of use in demanding laboratory and industrial environments. With a spacious 450-liter chamber, this oven is ideal for high-volume sample drying, curing, aging, and general heating applications where temperature uniformity is critical.

Simple, Intuitive Control (OF3/H Model) This general-purpose model is designed for quick and straightforward operation.

• Bright VFD Display: Features a clear, high-visibility Vacuum Fluorescent Display (VFD) that shows both the set temperature and the actual current temperature simultaneously, allowing for at-a-glance monitoring.
• User-Friendly Dial: A large, quick-adjustable dial knob allows for effortless setting of temperature values and selection of functions, simplifying the user experience.
• Preset Function: Save time by programming up to three of your most frequently used temperature settings for instant recall.

Superior Performance and Efficiency

• Rapid Heating: Reaches a maximum temperature of 200°C (392°F) quickly, minimizing wait times and increasing throughput.
• Advanced PID Control: A sophisticated microprocessor PID controller ensures precise temperature regulation, with options for three-point calibration and automatic tuning to optimize performance.
• Forced Air Convection: Two powerful yet noiseless sirocco fans generate vigorous air circulation throughout the chamber. This guarantees exceptional temperature uniformity, prevents temperature stratification, and enables rapid heat-up and recovery times after door openings.
• Optimized Insulation: An advanced insulation system enhances energy efficiency by minimizing heat loss. This keeps the exterior surface cool to the touch, even during high-temperature operation, improving both safety and energy conservation.

Built for Convenience

• Easy Maintenance: The interior chamber features rounded corners for easy cleaning and optimal airflow. The heating element is protected by a corrosion-resistant Incoloy sheath, and the interior is constructed from durable stainless steel.
• Dual Timers: Flexible dual wait on/off timer modes can be set from 1 minute up to 99 hours and 59 minutes, allowing for automated and unattended operation.
• Connectivity: A standard USB port and RS-232 port enable external control and data logging, allowing the oven to be integrated into automated systems. For advanced monitoring, the unit is compatible with the LC Connected mobile system (requires optional LC GreenBox).
• Mobility: Equipped with durable casters for easy relocation and installation within your facility.

Uncompromised Safety Features

• Keypad Lock: Prevents accidental or unauthorized changes to operating parameters.
• Power Interruption Recovery: Automatically resumes operation after a power failure, ensuring process continuity.
• Comprehensive Protection: Features built-in over-temperature and over-current protection circuits.
• Audible and Visual Alarms: Alerts the user immediately if the door is left open, preventing heat loss and protecting samples.
