Exeon were asked to provide a Ventilation system for a Powder Coating process at a large Tank Manufacturer.
The powder coating process was a very large source of heat gain in the area. Whilst the Oven was insulated, the heavy steel plates when they left the oven on the Rail retained large quantities of heat. There was a wall fan area which cooled the plates but released further heat into the background area.
The Process was required to be kept clean, as the plates could attract dust which spoilt the finish, so inlet air was required to be filtered.
An AHU had been proposed but the expense of this far exceeded what was available within the budget.
Exeon supplied and installed a large Powder coated hood above the exit to the Powder coating process, with extract grills, to retain the initial high levels of heat immediately after the Oven, and before the Wall fan area.
This had a high temperature extract fan to avoid issues with ‘spiking’ of heat through any factory shutdowns / power failures.
The Wider factory required high levels of background Heat extraction which was achieved through Wall fans with Discharge cowls.
Both the above extraction requirements required make-up air to give a balanced atmosphere and ensure negative pressure was not achieved on the building. Exeon supplied and installed Wall Supply fans with filtration system to allow make-up air to be provided, which also provided ambient cooling for operatives.
