We recently completed the overhaul of four large HVAC (Heating, Ventilating, and Air Conditioning) fans that were fitted inside one of our customers buildings. The overhaul was to include a full rewind of each motor and modifications to be made that the customer specified. This work had to be done over four successive weekends, removing them overnight on a Friday night and having them installed and working ready for the customers staff returning on a Monday morning.
The first stage of any large scale project such as this is to carry out a site assessment. Our engineering and sales team visited the customers site to investigate the location of the fans, take photographs, and assess what challenges needed to be overcome to perform the work within the customers timescale.
These fans were 7 feet of the ground with about 1 foot clearance above. Three of the fans would have to be carried down 3 flights of stairs to be removed from the building, the other fan would require narrow section scaffold and lifting clamps to take it down. Large sections of duct would have to be removed before the fans could be removed.
Our electro-mechanical engineering team studied the problems, devised an action plan in co-operation with the customer and drafted the relevant safe methods of working and method statement documentation. This with a quotation for the work to be carried out was sent to the customer and accepted.
The first fan was removed for overhaul and rewinding, all the work taking place over the weekend period.
The work went well and over the weekend the fan motor was rewound, overhauled, fitted with new SKF bearings and tested. It was re-installed on site ready for the start of work on the Monday morning.
Over the next three weekends the other three fan motors were removed, rewound, overhauled and replaced, all within the required timescales.
If you have a large project like this, contact Fletcher Moorland. We have the expertise and experience to carry it out on your site to the timescales you require, 24 hours a day, 7 days a week.
