Could you build a heat exchanger that exactly matches the existing dimensions (footprint) of our current system?

Yes, in many cases that is possible. We regularly replace existing heat exchangers without the need to modify the entire system.

We can design a heat exchanger with the same footprint, connection dimensions and installation dimensions as the existing system. This often means that pipework, foundations and supports can be reused, thereby significantly reducing downtime and installation costs.

Furthermore, thanks to modern design techniques, it is often possible to achieve a higher heat capacity or more efficient heat transfer within the same dimensions.
