Product Overview
3Professional Product Overview
The ALC-SCIENTIFIC Digital Hot Air Oven is designed for controlled heating, drying, moisture removal, thermal ageing, preheating and laboratory heat-treatment applications. The oven uses electrically generated heat with either natural convection or forced-air circulation to maintain the selected chamber temperature. A digital temperature controller enables operators to set and monitor process conditions, while an insulated chamber helps reduce heat loss. Depending on the selected configuration, the oven may include a stainless-steel interior, adjustable ventilation, programmable timer, overtemperature protection, removable shelves and data connectivity. It is suitable for pharmaceutical, research, food-testing, academic and industrial quality-control laboratories.

Heating Technology
8Working Principle
The Digital Hot Air Oven converts electrical energy into heat through heating elements positioned around or beneath the internal chamber. The controller continuously receives temperature information from the chamber sensor and switches or regulates the heaters to maintain the selected set point. Heat is distributed either by natural air movement or through a fan-assisted circulation system. The selected convection type affects heating speed, chamber uniformity, airflow strength and sample suitability.
Natural Convection
Heated air rises naturally while cooler air moves downward. This configuration provides gentler airflow and is suitable for samples that may be disturbed by strong circulation.
Forced Convection
A fan circulates heated air throughout the chamber, generally improving heat transfer, drying speed and temperature distribution across multiple shelves.

Internal Chamber
Stainless-steel chamber with smooth cleanable surfaces and removable shelving for routine laboratory use.
Heating System

Shelving
Chrome-plated racks, stainless-steel wire shelves or perforated trays, depending on chamber capacity.
Door System
Insulated solid door with a high-temperature seal. Glass observation door may be offered as an option.
Thermal Insulation
High-temperature insulation between the internal chamber and outer cabinet helps reduce external heat and energy loss.
