Modine Expands Effinity93 Unit Heater Line

Modine Manufacturing Company announced an expansion of its popular Effinity93 unit heater last month. At 93 percent thermal efficiency, Modine boasts that the Effinity93 is the most efficient gas-fired unit heater in North America. The Effinity93 will now be available with input ratings of 85,000 and 110,000 British thermal units (BTU) per hour.

Modine’s Effinity93 is designed to give commercial HVAC users a more efficient way of heating their buildings. This will allow them to lower their energy bills, decrease fuel consumption and keep their environments controlled for optimal comfort and safety. In doing this, the company has expanded the original unit heater line from six to eight models, now ranging from 85,000 to 310,000 BTU/hr.

The Effinity93 features Modine’s Conservicor technology, which is comprised of a high-grade stainless steel secondary heat exchanger. This technology is specifically designed to withstand the acidic condensate that is a byproduct of the combustion process.

“The Effinity93 has been wildly popular since its introduction in 2009,” said Matt McBurney, vice president of Modine’s Commercial Products Group.

“The Effinity93 was developed to provide commercial HVAC users an option that provides greater energy efficiency, drives down energy costs and creates a substantial return on investment. Whether it’s an addition to a new building project or a pre-existing facility, the two new sizes mean we can extend those benefits to even more applications.”
