As buildings age, much of the original ventilation equipment ceases to function. Coils become blocked, filter frames deteriorate, the bottom of units rust out due to water damage. Routine maintenance procedures do not cover these sort of problems. Old equipment often has a high maintenance requirement.

Failure to meet current performance requirements is also another reason to refurbish failing systems.

VES engineers can upgrade your equipment and give it a new lease of life. This starts with a site survey, report and quotation, tailored to your technical and budgetary requirements.

Once a programme of work has been agreed, method statements and risk assessments will be issued, a detailed site survey will include airflow, pressure and noise measurements as necessary.

The Refurbishment Division is part of the VES Andover organisation, and can draw on considerable resources for both manufacturing and personnel requirements. All project management and site work is carried out by VES employees.

VES also undertake small jobs, for example replacing an unsuitable noisy extract fan with a silenced unit, or straight forward replacement of defunct equipment.

The VES Flat Pack AHU Installation Service

Flat Pack installation of air handling units and other VES products can result in big savings, including builders work costs, crane hire, road closure and out of normal hours working.

VES will build your air handling unit in difficult locations and take full responsibility in ensuring the plant will fit the space available and is correctly assembled.

A site survey is usually necessary for a trouble free installation.

VES engineers will man handle the components to the position required. All you need to do is provide a level surface for the unit and have cleared the area of old plant and debris. For larger units specialist lifting equipment may be provided.

Only skilled VES employees undertake this work, ensuring high standards and completion in the minimum amount of time.

Case History

The Methodist Central Hall, London
Built in 1898, was converted in 2002 for the "Bloody Sunday" government inquiry. VES air handling units were installed by the Flat Pack team in a room converted to a plantroom. There was poor access to the room via a stairwell.

The equipment was designed and built in the normal way, and assembled in the VES factory without any fastners being fitted. After inspection it was taken apart into component pieces and rebuilt on site as a finished product.
