circulation oven

Product Introduction

Use electric heating and forced air circulation system to heat items Drying, baking, heat treatment, sterilization or constant temperature suitability test box equipment. It is due to Relatively small footprint, large studio capacity, and good temperature uniformity and other features, often used in situations where space and sample capacity are required.
It is used by industrial and mining enterprises, laboratories, scientific research institutions, etc. for drying, baking and melting wax. This electric blast drying oven is made of mirror stainless steel or high-quality galvanized steel plate studio, with a plastic-sprayed outer shell and a double-layer tempered glass observation window, which has a beautiful and novel appearance. Computer intelligent temperature control, overheating protection, time setting, good temperature control linearity, small fluctuations. It has tracking alarm function and stirred hot air circulation, with small heat loss.

Technical parameters

Working Principle

heating stage :
The electric heating element (nickel-chromium alloy heating tube) is energized to heat up, and transfers heat to the box through radiation and convection.

​forced convection:
The centrifugal fan drives the air to form a circulating air flow, which evenly covers the surface of the material and accelerates the evaporation of water.

​temperature regulation:
The PT100 platinum resistance sensor monitors the temperature in real time, and the PID controller dynamically adjusts the heating power to maintain the set value.

​Drying completed:
After drying, the hot air is discharged through the exhaust port to prevent the air pressure in the box from being too high.

Product Features

Efficient hot air circulation :
use Centrifugal fan With special air duct design, forced convection makes the temperature uniformity in the box reach **±1~2.5℃**, and the drying speed is 2~3 times faster than natural convection.

​Precise temperature control:
Equipped with microcomputer PID controller, supports 0.1℃ resolution, and can set the temperature range RT+10~300℃ , fluctuation degree ≤±1℃, suitable for precision experiments

​Security protection:
Multiple protections: over-temperature alarm, leakage protection, motor overload power-off, etc. to ensure equipment and operation safety

Explosion-proof design: Some models meet the requirements of explosion-proof environments (such as chemical flammable scenes)

​Durable and easy to maintain:
Stainless steel liner and high temperature resistant sealing strip, corrosion-resistant and easy to clean
Modular structure design supports quick replacement of fans, heating pipes and other components

​Energy saving and environmental protection:
Optimize the thickness of the insulation layer (5~7cm) and waste heat recovery system to reduce energy consumption by 20%~30%
