Electricity hot blast drying oven

Model: UT2035A

Electricity hot blast drying oven is a drying device that generates heat through electric heating elements and uses a fan to create forced convection for hot air circulation. Its core features are uniform temperature inside the chamber (typically with a fluctuation of ±1°C) and precise temperature control. It is widely used in industries and mines, research institutes, medical units, and other fields for sample drying, baking, sterilization, curing, and constant temperature testing. 

UT2035A Electricity hot blast drying oven is mainly used to measure the dimension change of plastic material after heating, suitable for plastic pipe, plastic sheet etc.     

General introduction

Electricity hot blast drying oven is a drying device that generates heat through electric heating elements and uses a fan to create forced convection for hot air circulation. Its core features are uniform temperature inside the chamber (typically with a fluctuation of ±1°C) and precise temperature control.

Key Features

  • Core working principle
  • Unique advantages
  • Control System Introduction
  • Security features

The core working principle is heating and forced convection circulation: 

When the device is powered on, the electric heating element (such as a nickel-chromium alloy heating tube) converts electrical energy into heat energy. The built-in centrifugal fan operates at high speed (usually 2800-4200 r/min), driving hot air to form forced circulation within the chamber. 

The optimized air duct design (such as 45°-60° inclined guide plates) can eliminate airflow dead zones, ensuring uniform temperature distribution. 

The temperature control system typically uses a PID intelligent algorithm and a Pt100 platinum resistance sensor to monitor and dynamically adjust the heating power in real time to maintain a stable set temperature. 

Some models are equipped with adjustable exhaust valves to discharge humid air and supplement dry air, maintaining drying efficiency.

Partition upgrade: (The partition is punched with stainless steel plate, which can solve the unevenness of the previous grid when placing items)

Controller thermal conductive plate: (although the controller is convenient to operate at the top, the hot air will run up after opening the door after use, affecting the control life, Type II increases the thermal conduction plate aesthetically beautiful and can effectively protect the controller)

Duct structure improvement: (redesigned strong convection duct for significantly improved uniformity)

Door handle upgrade: (Upgraded type seizure door handle, simple and light and durable to open and close the door)

Partition upgrade: (first use many spacers welded into the inner tank, put the partition on the box drawer type pull, I type drying box is hook type non-pullable)

Appearance upgrade: (While completing the overall performance improvement of the equipment, the appearance upgrade is beautiful and atmospheric.) )

Fan speed control function: (can adjust the wind speed)

Programmable controller: (standard 9999 cycle, 50-segment programming)

1, The microcomputer P.I.D temperature controller with over-temperature deviation protection and digital display is adopted, with timing function, and the temperature control is stable and reliable.

2, The upgraded sound and light alarm environment scanning microcomputer chip has stable data processing function

3, Overtemperature alarm, scheduled shutdown, call recovery, parameter encryption, temperature correction and other functions.

4, With power failure recovery function, after the external power supply suddenly loses power and comes back again, the device can automatically resume operation according to the original set program


★ Thoughtful safety protection design to achieve triple security protection for personnel, samples and equipment

★ Safety functions: sensor fault alarm, overtemperature alarm, separate over-rise preventer, separate over-temperature protector, overcurrent trip protection, etc.,

ISO 62 Moisture content test water absorption of plastics

ISO 62 Moisture content test,  Plastics — Determination of water absorption 

ISO 62:2008 describes a procedure for determining the moisture absorption properties in the“through-the-thickness”direction of flat or curved-form solid plastics. It also describes procedures for determining the amount of water absorbed by plastic specimens of defined dimensions, when immersed in water or when subjected to humid air under controlled conditions. 


The“through-the-thickness” moisture diffusion coefficient can be determined for single-phase material by assuming Fickian diffusion behaviour with constant moisture absorption properties through the thickness of the test specimen. This model is valid for homogeneous materials and for reinforced polymer-matrix composites tested below their glass transition temperature. However, some two-phase matrices such as hardened epoxies may require a multi-phase absorption model which is not covered by this International Standard.
