Modine’s PTS/BTS separated combustion unit is specifically designed for environments with hostile atmospheric conditions, such as chemicals, high humidity or negative pressure. This tubular heat exchanger is available in units rated from 150,000 to 400,000 BTU/hr. On these units, combustion air is brought in from outside the heated area, either from outdoor air or from an adjacent room, eliminating the need to use contaminated indoor air for combustion.


Effinity93® Condensing Unit Heater


At 93% thermal efficiency for all model sizes, Modine’s Effinity93® condensing unit heater features the highest efficiency available in North America for commercial and industrial,as well as residentially certified (sizes 110 and smaller) gas-fired unit heaters. This industry leading efficiency is a result of the coupling of our Conservicore®  secondary heat exchanger technology with our robust tubular primary heat exchanger design. The Conservicore® technology features a secondary recuperative heat exchanger fabricated from AL29-4C® stainless steel. This material is superior to other lower grades of stainless steel and aluminum, resulting in outstanding ability to withstand the corrosive environment of condensing gas fired equipment.

Available in ten model sizes with input ranges from 55,000 to 310,000 Btu/Hr, Modine offers application flexibility unmatched in the industry. The separated combustion units draw combustion air from outside to ensure that the unit will always have plenty of fresh, clean air for combustion while increasing the overall heating efficiency. Venting material to be used is PVC, an extremely cost effective vent system.

Whatever your heating, ventilating and air conditioning requirements, Modine  has the product to satisfy your needs.
