We were contacted by the facilities department at the Tower of London building as the existing heating pressurisation unit had failed. We carried out a full onsite survey and concluded that the unit was not financially worth repairing and due to the importance of the plant we recommended that it should be replaced for new.
We decided that with the available space we could convert the current system which was pressurisation by the pump (spill unit) to pressurisation by expansion, which is much more maintenance-friendly.
We attended site and removed the old unit and vessels and installed a temporary bypass with a high and low fault signal while the unit was out of service. This alerted the Tower of London maintenance team if the system required topping up or venting.
With the temporary bypass installed there was very little distribution to this very iconic and historic building.
We installed a PUK Autopress 2LC unit and three Lowara 1000 litre expansion vessels. We did have to carry out some minor pipework alterations to ensure the new unit is more accessible for future maintenance work but this was all part of the job.
We fully commissioned the new unit and left it in service. Our install team even had time for a quick selfie!!!
