1 PMI-IF-H High Efficiency Gas Heat Units

2 Mechanical High Efficiency Gas Fired Make-Up Air Units Price s new line of high efficiency indirect fired gas heating products are designed to meet the goals of all good building designs by reducing operating costs and minimizing environmental impact. The Challenge Table 1 Std Unit MUA Unit Design Conditions Btu/h-cfm Cooling Work Heating Work Watts/cfm Btu/h-cfm 80/67 to 57.6/57F to 70F (20% OA) /75 to 55/54.5F to 70F Almost all building heating systems are based on burning natural gas. Typically, the most energy intense unit in the HVAC system is the make-up air unit (see Table 1) which uses as much as five times the natural gas of a standard unit. While plentiful, the cost of natural gas is rising. Even though natural gas burns twice as clean as coal and other fossil fuels, it still contributes to climate change through CO 2 emissions. The challenge is to improve the gas heating efficiency which will reduce operating costs and climate change impact. The Solution Typical Make-Up Air System Price s new line of high efficiency indirect fired units can help reduce operating costs by 11% with a less than two year payback. Traditional gas heat units are only 80% efficient, meaning 20% of the available heat in the natural gas is going up the vent stack. The stack temperature on a traditional unit can be over 500 F that s heat that s not available for the building and higher CO 2 emissions that lead to climate change. The Price line of high efficiency units have an impressive stack temperature of only 100 F, and they are 90% efficient so almost all of the heat released during combustion is used in the building. 1 priceindustries.com

3 PMI-IF-H High Efficiency Units High Efficiency Indirect Fired Furnace At the heart of the high efficiency unit is the new indirect fired convoluted tube furnace. The furnace includes a specially designed heat exchanger to squeeze as much of the heat from combustion as possible and transfer it to the supply air stream. The furnace is constructed from stainless steel and other corrosion-resistant materials to provide reliability and longevity. Indirect Fired Design The furnace is indirect fired, meaning no products of combustion enter the supply air. This helps maintain good indoor air quality. The burners are modulating which also allows for great temperature control and comfort.

Single and dual path energy recovery is also available (see unit configuration). Up to four furnaces can be used in a 2 by 2 arrangement providing up to 1440 kbtu/h of capacity. priceindustries.com 2

5 Condensate Management Condensate Chase Neutralizing Kit Applying the Price high efficiency furnace is no different than any other gas heat product except for condensate. As the high efficiency furnace extracts the heat, the water vapor in the combustion gas starts to condense. This also happens with other high efficiency gas heat products such as home furnaces and condensing boilers. If the equipment is roof mounted in a climate where freezing conditions may occur, the management of the condensate is critical. Price recommends a drain inside the building under the unit. The condensate can be routed down through the curb to the drain. If the application requires the condensate drain line to be exposed to freezing conditions, field-supplied heat tracing is required. Price offers an optional neutralizing kit to raise the PH of the condensate where local codes require it. The kits can be factory mounted in the unit or shipped loose for field installation. priceindustries.com 4
