About This Project

The Mailbox, Level 7, Birmingham

The Mailbox is a 65,000sq ft open plan office area with on show mechanical services.


We have supplied and installed circa 60 LG VRF heat recovery fan coil units in the open plan area and large offices. We also fitted a mixture of wall mounted units and ceiling cassettes in the small offices and Bistro providing heating and comfort cooling. To distribute heated/cooled air to the space we have used high level swirl diffusers connnected to the fan cool units via spiral ducting.


We have supplied and installed 3 no. IV Produkt Air Handling Units with heat recovery and DX package heat pump to provide fresh air ventilation to the open plan office space.


We have upgraded the building incoming 28mm water supply to 42mm and also extended the landlords supply. This is to feed a Scuba combined 2200 litre cold water tank as well as pump booster set.


We have supplied and installed a 70L Megaflo, 800L Megaflo, and a 500L Megaflo water heater which provide hot water in various areas of the office. All water heaters have electric supplies to immersion heaters.


To each toilet block we have installed new sanitaryware appliances. For accessible toilet areas we have fitted compliant DOC M Packs therefore ensuring easy use. The school also required Cleaner’s Cupboards, so Air Cool have installed these with Birch Cleaner’s sinks with wall mounted bib taps.


Zip Arc G4 Hydrotaps and fonts have been installed in the coffee bar, bistro and mezzanine areas. These give instant boiling and chilled water and so adds a great facility to the office.
