Industrial Plant Automation & ControlMany facilities have more than one boiler for redundancy/reliability, such as schools and hospitals. Other facilities have installed or retrofitted multiple, modular boilers for various reasons other than energy efficiency. (First cost, space considerations, operator codes, etc.) If boilers are not optimized for efficiency, there is potential energy savings from installing an intelligent boiler sequence control.

Steam Trap Audits

Approximately 20% of the steam leaving a central boiler plant is lost via leaking traps in typical space heating systems without a proactive assessment program.
