Indosaw Hot Air Oven

Microcontroller-based lab oven for precise temperature control, with stainless steel chamber, fan, and digital display.

• The unit can maintain any desired temperature up to 150 °C (with a potential max of 250 °C), controlled by a micro-controller
• A fan for forced air circulation ensures the temperature is consistent throughout the inner chamber
• The inner chamber is made of rust-proof stainless steel and features an adjustable rack; customize the space to fit various sample sizes and quantities, accommodating 2 to 6 trays
• A 16×2 alphanumeric display with a backlight provides clear visibility of temperature and time settings
• An audiovisual alarm notifies the user of any temperature deviations, and an external exhaust outlet provides proper ventilation

This equipment, a type of laboratory oven or incubator, is designed for applications requiring precise temperature control. It's a versatile tool used across various fields, including research, quality control, and industrial processes, for tasks such as drying, curing, sterilization, and material testing. The design integrates robust construction with advanced electronic controls to ensure reliability and accuracy.

Construction and Chamber Design: The unit features a double-walled construction for efficient thermal insulation. The inner chamber is made from rust-proof stainless steel, a critical feature for durability and hygiene. Stainless steel is inert, corrosion-resistant, and easy to clean, making it suitable for a wide range of samples without the risk of contamination. The outer chamber is constructed from steel with a protective painted or powder-coated finish, which enhances its durability and provides resistance to scratches and corrosion from the external environment. Within the inner chamber, a stainless steel rack or shelf is provided. This rack is adjustable, allowing users to customize the interior space to accommodate different heights and sizes of samples. The capacity to hold 2 to 6 trays provides flexibility for processing multiple samples simultaneously, increasing efficiency. A fan for forced air circulation is also a key feature. This fan ensures a uniform temperature distribution throughout the chamber, preventing hot or cold spots and guaranteeing that every sample is subjected to the same thermal conditions for consistent and accurate results.

Electronic Control and Performance: The oven's core is a microcontroller-based digital display of temperature, which provides precise control and monitoring. The 16×2 alphanumeric display with backlight ensures that the temperature and time settings are clearly visible, even in low-light conditions. The unit's temperature range is from ambient to 150 °C, with an accuracy of ±2 °C. While the prompt also mentions a maximum of 250 °C, the specific range listed here is up to 150 °C, which is suitable for many common laboratory applications. Users can program both the desired temperature and the duration of the heating cycle, which is a key feature for automated processes and repeatable experiments. For safety and optimal performance, the unit includes an audiovisual alarm that activates if the temperature deviates from the set point. This feature is crucial for protecting samples and ensuring the integrity of experiments. The external exhaust outlet is another important safety feature, allowing for proper ventilation of fumes or gases that may be released from samples during heating. The system operates on a standard 230 V, 50 Hz AC power supply, but for consistent performance and to protect the sensitive electronics, the use of a voltage stabilizer and proper earthing is strongly recommended. The inner chamber's size of 60×60×60 cm provides ample space for a variety of tasks, balancing a compact footprint with a generous working volume.
