🔥 Thermal Oil Hot Air Circulation Oven | Precision Industrial Heating Equipment
Product Overview
The Thermal Oil Hot Air Circulation Oven is a high-performance industrial heating system designed to deliver precise and stable temperatures from 80°C to 300°C. By using heat transfer oil as the heating medium, it provides uniform and efficient heat distribution for a variety of manufacturing and thermal processing applications.
Built with a SUS304 stainless steel inner chamber and A3 cold plate exterior, this oven ensures durability and resistance to corrosion. Its aluminum silicate fiber insulation layer guarantees superior heat retention and energy savings. The low-pressure, liquid-phase operation ensures maximum safety, maintaining temperature accuracy within ±1°C, ideal for demanding industrial environments.
Key Benefits for Buyers

Working Principle
This thermal oil circulation oven functions through a closed-loop heat transfer system. Heated thermal oil circulates at 2.3–2.7 m/s, transferring heat through exchangers to maintain uniform chamber temperature.
A built-in forced air circulation distributes heat evenly, ensuring every part of the material receives equal thermal exposure. The large thermal oil capacity (up to 3 tons) provides remarkable stability, preventing sudden temperature changes and guaranteeing ±1°C precision across the oven’s entire range.
