McCallum can also carry out retrofit's to existing Calorifiers and Cylinders on site to bring them into line with the current HSE Guidelines for the control of Legionella L8.

These works include, Installation of Manhole Hatches to enable internal inspection and cleaning, Supply and fitting of de stratification pumps and internal sparges to ensure the complete contents of the vessel can be brought up to temperature thus killing bacteria and reducing stagnation, Connections for low level temperature indication and fitting of internal drip pipes to enable the contents of the vessel to be fully drained via a hand pump. We can also supply and fit immersion heaters for summer use or adapt existing Calorifiers to be used as buffer vessels with Plate Heat Exchangers. McCallum offer a no obligation free inspection and report on existing installations with respect to the Calorifier's compatibility with L8.
