70L `Vertical Electric Forced-Air Drying Oven`

Research-grade laboratory product

Product Overview

This 70 L vertical electric forced-air drying oven is designed for laboratories, research rooms, university facilities and pilot environments that need stable heated-air drying in a compact and practical format. The unit combines a metal cabinet structure, a viewing window, a metal inner chamber and 2 removable shelves, creating an enclosed working space for routine thermal processing and daily laboratory use.

It can be used for drying glassware, heating and conditioning samples, baking materials, carrying out pre-treatment steps and supporting constant-temperature observation during general laboratory work. The forced-air drying design helps improve temperature distribution inside the chamber, making the oven suitable for tasks that require controlled hot-air circulation, repeatable heating conditions and reliable batch handling within the stated chamber volume.

The chamber size is 400(W) x 350(D) x 500(H) mm, while the outer size is 550(W) x 530(D) x 810(H) mm. The oven provides a temperature range from RT +10 C to 250 C, 0.1 C resolution, temperature stability of <=0.5 C, temperature uniformity of <=2.0%, and a timing range of 1 to 9999 min. The listed rated power is 1050 W, and the supply voltage can be adjusted according to specific requirements for the intended installation environment.

The oven must be operated within an ambient temperature range of 5 to 40°C to maintain specified performance. The unit requires a stable power supply with the correct voltage as configured for the installation environment.

Ambient temperature range: Operate the oven only in an environment with ambient temperature between 5°C and 40°C.
Power supply configuration: Verify that the power supply voltage matches the oven's configured voltage before operation.

FAQ

How does the forced-air circulation design affect temperature uniformity in this 70 L vertical oven compared to natural convection?

The forced-air circulation actively improves hot-air distribution inside the chamber, achieving a specified temperature uniformity of ≤2.0%. This is a practical advantage over natural convection ovens, which rely on passive air movement and can develop larger thermal gradients, especially in deeper loads or multi-shelf configurations. The ≤0.5 °C temperature stability further supports repeatable conditions during drying or heating cycles.

Can the 220 V power supply be configured for other regional voltages, such as 110 V or 240 V?

Yes, the supply voltage is adjustable according to specific installation requirements. The standard listed configuration is 220 V, but the unit can be set for other regional voltages. It is recommended to confirm the exact voltage requirement with the technical sales team before finalizing the order to ensure compatibility with the intended laboratory infrastructure.

What is the maximum programmable time for a single heating cycle, and does the oven support unattended operation?

The built-in timer covers a range of 1 to 9999 minutes (approximately 6.9 days), suitable for extended batch drying or heat treatment cycles. However, the standard oven does not include a programmable temperature controller; an optional controller with up to 99 segments and 99 program groups is available for complex, unattended profiles. For safe unattended use, proper laboratory protocols and the optional RS485 monitoring interface should be considered.

Assessment

The 70 L vertical forced-air drying oven is specified for RT+10 °C to 250 °C operation with 0.1 °C resolution, ≤0.5 °C stability, and ≤2.0% uniformity, making it suitable for routine drying, baking, and sample conditioning. Installation must respect the 5–40 °C ambient operating window and the RT+10 °C minimum temperature limit.

Positive

Forced-Air Circulation with ≤2.0% Uniformity: The forced-air design promotes hot-air movement inside the 70 L metal chamber, supporting the stated ≤2.0% temperature uniformity for more consistent batch drying and heat-treatment conditions.
Fine Temperature Resolution and Stability: A 0.1 °C resolution and ≤0.5 °C temperature stability enable repeatable constant-temperature processing across the RT+10 °C to 250 °C range for routine laboratory workflows.

Trade-offs

RT+10 °C Minimum Temperature Limit: The oven cannot operate below 10 °C above ambient temperature, so near-ambient or low-temperature drying processes are not supported by this unit.
5–40 °C Ambient Operating Window: Rated performance assumes an ambient temperature of 5–40 °C; installation in unconditioned spaces outside this range may require additional environmental control to maintain specifications.
