Reusing generated heat saves printing plant

The Munters solution

Two Munters Thermo-Z® air-to-air heat exchangers, one on each incinerator, capture the exhaust heat and use it to heat outside air for plant makeup air in winter. Each heat exchanger is part of a complete packaged heat recovery system that also includes supply and exhaust fans, dampers, and filters.

In optimal conditions, the systems heat outdoor air from -10°F to 130°F using 250°F exhaust from one incinerator and 350°F exhaust from the other. Combined, they can transfer over 10,400,000 BTUs per hour.

The temperature of the space is controlled to maintain a consistent 130°F by modulating the hot gas flow through the heat exchanger. Munters air-to-air heat recovery system has successfully helped the printing plant recycle energy and save on costs.
