Steam generators are normally insulated by a sheet-metal skin which is held a few inches away from the machine by a series of skeleton metalwork rods. The space between the skin and the machine is then stuffed with glass fibre. We needed to develop an alternative that was less dusty and easier to maintain.


We designed a jacket system using high-temperature cloths and infills. The jacket is assembled almost like a jigsaw, which means it can be easily removed for machine maintenance and replaced quickly afterwards, reducing downtime and saving money. The new jacket also brings improved health and safety features for those working with the machines.


The client can now carry out maintenance without worrying about the insulation system. Jackets can be made to order for various-sized machines, and they deliver time savings and value for money.
