140L `Vertical Electric Forced-Air Drying Oven`

Research-grade laboratory product

Product Overview

This 140 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 450(W) x 550(D) x 550(H) mm, while the outer size is 590(W) x 730(D) x 860(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 1550 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 proper performance. The supply voltage must be adjusted according to the specific requirements of the installation environment to ensure safe operation.

Ambient Temperature Constraint: Ambient temperature should be between 5 and 40°C.
Supply Voltage Requirement: Supply voltage must be confirmed for the intended installation environment.

FAQ

What forced-air uniformity can be expected from the 140L vertical blast drying oven for heat-sensitive sample conditioning?

Temperature uniformity is ≤2.0% across the 140 L chamber, with stability ≤0.5 °C and 0.1 °C resolution, supporting controlled hot-air circulation for repeatable drying and heat treatment. The forced-air design improves distribution, but for highly sensitive materials, optional programmable controllers (99 segments × 99 groups) and multi-point recorders can enhance monitoring.

Can this 140 L drying oven be integrated with existing laboratory data collection or remote monitoring systems?

Yes, an optional RS485 communication interface is available for connection to a printer or PC for temperature monitoring. The oven also offers an optional programmable temperature controller, multi-point temperature recorder, and side test port, enabling integration into automated workflows or data logging setups typical in research environments.

What power supply and installation infrastructure are required for the 1550 W vertical blast drying oven?

The standard configuration is 220 V, but the supply voltage is adjustable according to specific requirements. With a rated power of 1550 W and gross weight of 75 kg, the unit requires a dedicated circuit and adequate benchtop or floor spacing for its outer dimensions of 590(W) x 730(D) x 860(H) mm, plus clearance for ventilation and safe operation at ambient temperatures of 5 to 40 °C.

Assessment

The AF-LE-E-DRYC-0140-V220 140 L vertical blast drying oven is specified for forced-air circulation with 0.1 °C resolution, ≤0.5 °C stability, and ≤2.0% uniformity across an RT+10 to 250 °C operating range, making it suitable for routine drying, baking, and sample conditioning. Installation is constrained by its 1550 W load, adjustable supply voltage, 5–40 °C ambient range, and inability to set below RT+10 °C.

Positive

Forced-air circulation improves heat distribution: The forced-air drying structure is specified to improve hot-air circulation and heat distribution throughout the 140 L chamber, supporting controlled hot-air processing and batch handling.
Fine temperature control and stability: With 0.1 °C resolution, ≤0.5 °C temperature stability, and ≤2.0% uniformity, the oven supports repeatable constant-temperature drying and heat-treatment conditions.

Trade-offs

Ambient and minimum setpoint limits: The oven cannot operate below RT+10 °C and requires a 5–40 °C ambient environment, so it is limited to heating-only applications rather than below-ambient conditioning.
Voltage confirmation and electrical load: The 1550 W rated power and adjustable supply voltage require the buyer to confirm the site voltage and provide adequate electrical infrastructure before installation.
