The Adelphi Building, WC2, is one
of London’s most iconic landmarks.

A little after a year ago, work began
on the phased refurbishment of the
building’s chilled water system that
serves several floors of office
accommodation.

A major component of this project
centred on the replacement of 20
year old fan coil units on the 7th
floor by 148 modern Ability
Projects ceiling recessed 4-pipe
‘Trojan’ fan coil units with capacities
between 0.5 to 2kW (cooling) and 1
to 3kW (heating), supplied with
Ability fitted Trend BMS controls.

This order has recently been
augmented by one for 112 Trojan
units for the 11th floor bringing the
uptake to date to 250 fan coil units.

All units feature 2-port valves and
fresh air intakes on the discharge
plenum side and run at an elevated
chilled water temperature of 12/16 in
order to obviate the formation of
condensate. The Trojan units in the
latest order however, will have quick
release electrical boxes with snap-in
electrical terminals to allow quick
and easy maintenance in a busy
office environment.
