Refurbishment

Repair and Refurbishment

Specialist Site Services can refurbish any make or model of existing air handling or packaged air conditioning equipment, including those supplied by any other manufacturer.


Why Refurbish?

The refurbishment of existing air-handling and packaged air-conditioning equipment whilst remaining on site is practical at so many levels that it is considered by many engineers as the first option, rather than strip out and replace with new. Those with experience of on-site refurbishment quickly realise the benefits, which include;

Cost

Typically, the refurbishment cost of an existing unit is between 35-50% of the cost of new equipment, and this excludes the removal and re-installation costs. In addition quotes can be provided to give an itemised list, so only essential works can be completed if the budget doesn’t stretch very far. New components can often be flatpacked to further save craneage and road closure costs.

Less disruption and more flexibility

Works can be scheduled so as not to interfere with a clients business and their neighbours and carried out overnight or at weekends, particularly with noisy works.

Refurbishment is usually a much quicker option from start to finish than replacement, and also gives the choice of separating the necessary works and completing out at different times for much greater programming flexibility. For instance, a gas burner can be replaced one weekend, casework and other components on another and then a controls upgrade that can integrate with BMS carried out at a later date, with other equipment on site.

Improving an existing unit specification


This could include adding a cooling coil, heat recovery, higher grade filtration or upgrading fan performance. Efficiency and therefore running costs can be improved by a considerable margin.

What can be refurbished?


This is the starting point when deciding whether to refurbish, as much can be achieved with units in poor condition. An example of what can be done with a unit in very poor condition is shown below and illustrates the in-depth refurbishment process that VES offer.

If properly maintained, Specialist Site Services can give another 15 years working life to existing equipment.


Roof Replacement

The roof panels are often the main cause of deterioration of an expensive AHU and, depending on budget, this can be treated or replaced. On units with high suction pressures, water is often drawn in through gaps in roof joints causing rusting.



Specialist Site Services can easily replace damaged top panels and add an external covering. For large roofs, particularly those with irregular shapes, Specialist Site Services offer a polybutyl seamless roof, which is offered with a 10 year guarantee. This is particularly useful on units with high suction pressures that tend to pull water through roof sections.

Heating and Cooling Coils

For units with restricted access, replacement coils can be provided in sections which are then joined on site, replacing valves and actuators as required. Coils can also be flatpacked to suit further restricted access situations.



Gas Burners

Specialist Site Services can repair or replace any make or model of gas heater in AHUs.



Dampers

Jammed dampers are one of the biggest causes of incorrect AHU operation and can easily be repaired or replaced.



Filters


Many older units now have poorly fitting filters allowing bypass of unfiltered air. Specialist Site Services can replace filter frames to prevent this and often fit higher grade filters as required.



Fans

All fan types can successfully be repaired or replaced. Also, fans can often be replaced with the latest energy efficient direct drive fans, as below, and inverter controlled. Replacing old forward curved fans with new plug fans can use between 15-20% less energy.
