Product Information -

The PMI-IF-H series are indirect fired make-up air units that utilize premier 90% efficient stainless steel convoluted tube heat exchangers. The new 90% furnace is capable of reducing operating costs by up to 11% as well as reducing C02 emissions. By separating combustion air from the supply air, the unit is able to maintain excellent indoor air quality (IAQ). These efficient gas heat units can be used in schools, offices, and institutional projects - anywhere that IAQ is paramount.
