What the notice says

This is the replacement of the Non Section 12 BCV Direct Expansion (DX) Split cooling. This will be 700 units on Bakerloo and Victoria Lines. These systems in the Non-public equipment (Secure) rooms prevent operationally critical assets from overheating and failing (e.g., signalling, power, communications systems), potentially disrupting Railway Operations and in Non-public staff rooms they provide a safe working environment in compliance with Health & Safety at Work Regulations helping to reduce financial maintenance pressure long term and adhere to climate change legislation
