Product Overview

The Natural Convection Oven utilizes the principle of hot air rising naturally inside the chamber, providing a quiet, low-dust, and gentle airflow heating environment. It is widely used for drying, baking, wax melting, heat treatment, and material processing applications. With precise temperature control and programmable operation, it provides stable and reliable thermal conditions for laboratory research and industrial applications.

Product Highlights

High Precision PID Control

Advanced PID temperature control enables rapid heating, accurate temperature regulation, and stable long-term operation.

Premium Stainless Steel Chamber

Mirror-finished stainless steel inner chamber with four rounded corners reduces residue accumulation and simplifies cleaning. Adjustable shelf supports allow flexible configuration for different applications.

Programmable Operation

Supports 30 programs with up to 99 steps. Each step allows 0–5999 minutes timing settings, preset start and stop functions, and adjustable circulation fan speed.

High Temperature Resistant Seal

Ceramic fiber door sealing material provides excellent heat resistance and ensures reliable performance during continuous high-temperature operation.

Independent Safety Protection

The independent over-temperature alarm system automatically stops operation when abnormal temperature conditions occur.

Multi-stage Temperature Control

Multi-segment temperature slope programming simplifies complex experiments by automatically executing preset temperature targets and process times.

Optional Data Communication

Optional printer and RS485 interface allow connection with computers or printers for temperature monitoring and data recording.
