    Through extremelly challenging conditions following the damage caused by Hurricane Sandy, MPN and CIeaver-Brooks delivered operational boilers back to 2 Gold Street on time and in line with the high standards expected by TF Cornerstone Properties. From the rehabilitation kick-off to the final operator training, MPN's staff provided a level of dedication and support that would assure a successful outcome.

    Arrow Linen

    By installing the Cleaver Brooks HAWK ICS upgrade, Arrow Linen received a rebate from National Grid in the amount of $74,813.00 and significantly reduced our fuel consumption. Resulting ROI was approximately 1.5 years.

    Mather Hospital

    Mather Hospital

    The project (which included a new fuel oil pump station as well) was completed prior to the start of the full winter heating load season. The tie-in with the hospital’s BMS allows the operators to monitor and manage the boilers and the overall heating plant at its highest possible efficiency. This now helps the hospital to achieve substantial fuel cost savings while being environmentally friendly.

We matched these boilers with a Trane Tracer SC web based BMS and the customer couldn’t be more satisfied.
