These are high-performance ovens designed to pre-heat drums / pails of chemical material, while homogenizing both the components themselves and their temperature inside the containers, thanks to an adjustable rotating movement.
This is useful to reduce drastically both the materials’ melting time (up to 1/3 less than normal) and energy consumption (again up to 1/3 less than normal) compared to traditional ovens. Moreover, standard devices tend to heat too much the terminal areas of the drums and way less the central area. This phenomenon causes significant temperature differences, resulting in damages to the materials and the shortening of their application time. However, this is just a problem of the past thanks to our rotating pre-heating ovens!
The heating process is possible thanks to a continuous forced ventilation system, which comprises groups of long-lasting and high-performance armoured resistors. The air inside each one of the oven’s areas is sucked upwards by fans and funnelled into the supply duct. There, it is heated while it goes through the aforementioned arrays of heating elements. Hot air is eventually redirected into the oven’s rooms from below. Together with the thermal insulation provided by thick layers of mineral wool covering all walls, this system guarantees the homogeneous heating of all the working zones of the equipment.
The main features of these pre-heating rotating ovens are:
- Structure designed to optimize both structural integrity and thermal insulation.
- Customization of the number of modules and heating zones (each zone has a maximum capacity of two 200-lt drums).
- Digital temperature adjustment, which is independent for each zone.
- Maximum temperature of 130°C (higher upon request) with an accuracy within 4%.
- Timer to turn on/off the scheduled heating for each zone.
- Constant temperature check thanks to digital devices and probes.
- Electromechanical safety thermostat to cut power when the maximum temperature threshold has been exceeded.
- Double doors with automatic locking system to ensure optimal thermal insulation and proximity sensors with immediate-release system in case of accidental opening.
- Bunding vats to contain leaks in each zone.
- Adequate dimensions to ensure that there is ample room for maneuver, both when loading and unloading trolleys.
- Trolleys that can be fully extracted thank to guides on wheels specific for high temperatures.
- General control board for power supply and temperature regulations.
- Heating groups with arrays of separate resistors to maintain the correct temperature after it has been reached and to optimize energy saving.
- Touch screen panel to program all working parameters independently for each zone (i.e. temperature, drum rotation speed, timers, temperature for each phase, etc…).
- Internet connection for remote assistance.
- Warning e-mails in case of malfunctions.
