Modine Manufacturing Company today announced the introduction of its Effinity93 with Conservicore™ technology, which is designed to be the most efficient gas-fired unit heater in North America. A full line of six models ranging from 135,000 to 310,000 BTU/hr - all operating at 93 percent efficiency - gives commercial HVAC users a more efficient way of heating their buildings so they can dramatically lower their energy bills, decrease fuel consumption, and keep their environments controlled for optimal comfort and safety.

The Effinity93 (Model PTC) features Modine’s Conservicore technology, a high-grade stainless steel secondary heat exchanger specifically designed to withstand the acidic condensate that is a byproduct of the combustion process. This technology offers greater durability than standard aluminum secondary heat exchangers offered by other manufacturers, according to the company.

Users of the Effinity93 will also benefit from a design that promises faster installation with lower installation costs. It can be vented as either a two-pipe or concentric vent system for maximum flexibility, with either 3-in. or 4-in. PVC vent piping for quick, simple and cost-effective installations. The Effinity93 delivers 93 percent efficiency in the same box size as Modine’s 80 percent efficient PTS model line. Another standard feature of the Effinity93 is a Contractor Convenience Package that allows for easy connectivity and troubleshooting.
