Press shop with HVLS ceiling fans above the mechanical presses and stacked material

HVLS Ceiling Fans in a Metal Pressing and Fabrication Plant

A metal pressing and fabrication plant. The client is not named at their request; the installation photographs are our own.

Project Challenge

The Building and the Problem

A high-bay pressing hall with mechanical presses running continuously, material stacked along the aisles and people working at fixed stations. Heat from the presses and from the building fabric collected at roof level, and the existing floor-standing fans covered only the stations nearest them while occupying floor space that material handling needed.

Customer pain points

  • Heat generated by the machinery accumulated because it was not discharged in time, which in a press shop is a wear problem as well as a comfort problem
  • Floor-standing horn fans obstructed the placement of material and reduced production efficiency
  • Dozens of small fans meant dozens of motors to maintain and a total power consumption that was hard to justify
  • Some bays had material stacked to height, so airflow at floor level did not reach the people behind it
Our Solution

What Was Installed and Why

Industrial HVLS ceiling fans over the press lines and the machining rows, positioned to clear the crane and lighting runs, with big movable floor fans retained at the fabrication benches where the work moves between positions and a fixed installation would have been wrong within a month.

1

Fan positions planned around the structure

Positions were set against the roof structure and the crane travel rather than by dividing floor area, because that is what determines real coverage in a building with stacked material.

2

Ceiling fans for the fixed stations

The press and machining rows are permanent, so the coverage per fan of the industrial range is the efficient answer and the floor stays clear.

3

Movable fans where the work moves

At the fabrication benches the hot spot follows the job, which is exactly the case the wheeled HVLS format exists for.

4

Supply matched at the factory

Motors were wound for the grid voltage on site so the installation was a connection rather than a transformer job.

Quality Control

What Was Checked Before Despatch

  • Stator withstand-voltage testing and blade dynamic balancing on every unit before despatch
  • Functional test with the controller fitted prior to crating
  • Mounting detail issued for the specific roof structure with loads at the fixing point

Final result

Air movement across the whole hall rather than at the stations nearest a fan, the floor freed of the drum fans that had been obstructing material handling, and a single controller type across the installation.

Customer benefit

A workshop where air movement at the working plane is designed rather than improvised, with far fewer motors to clean, service and replace.

Questions

Questions About This Installation

Yes, with the positions planned around the crane travel and the rail height. Send the clear height to the underside of the rail and the rail spacing and we will confirm which diameter can be hung and whether the fans sit between bays.

It reduces coverage, which is why the layout is drawn rather than calculated from floor area. Where material is stacked to height, portable fans at the aisle ends usually fill the gap better than another ceiling fan would.

Because the fabrication benches move. A wheeled fan follows the work; a ceiling fan does not. Most real workshops end up with a mix for exactly this reason.

HVLS fan installation is normally one to two working days per building using a scissor lift and two or three people, with the final connection made by a licensed electrician.
