Heating capacities range from 100,000 to 1,200,000 BTU/Hr and air flow volumes are available up to 15,000 cfm. A modular design concept enables the flexibility to customize each product for its application. Modules are then factory assembled and wired to minimize field installation labor. The result is a semi-custom product at an attractive cost. Indirect Gas-Fired Furnaces The Greenheck furnace is designed for top-notch performance and long life, combining quality components with expert craftsmanship. Unique to our furnace is a post purge cycle, which runs the combustion fan after the unit is shut down to vent hot air and moisture out of the heat exchanger. The elimination of these corrosion catalysts adds years to the life of the heat exchanger. Other key features of our furnace are listed below: • Power vented • 80% thermal efficiency • Seamless tubes • Electronic staged gas controls • Electronic modulating gas controls • Aluminized steel or stainless steel heat exchanger • Direct spark ignition system • Easy access burner controls • ETL listed to ANSI Standard Z83.8 • Solid state automatic ignition module Vibration Isolators The entire fan and motor assembly is mounted on vibration isolators to minimize noise transmission into the building. Neoprene isolators are standard on all units, spring isolators are optional. IGX-HV shown with horizontal discharge. reliable Fan Performance Air performance ratings from Greenheck’s AMCA registered test chamber ensure accurate data. Fans are constructed of heavy gauge steel and designed for high efficiency and low sound levels. Wheels are statically and dynamically balanced to ensure vibration free operation. control center The control center includes the following standard components: • Magnetic motor starter with solid state overload protection • Control transformer • Disconnect switch • Separately fused motor • Distribution terminal strip Premium grade control components are selected for reliable operation. All electrical components are UL Listed, recognized or classified. Control centers are factory prewired for single point power connection. Factory Wired and tested All units are tested prior to shipment. Units are checked for vibration and proper operation. 3 Control options Basic bimetal thermostats with mercury switches or fully programmable electronic thermostats are available as part of your IGX-HV system. Match your heating, cooling, staging, and operational requirements to the appropriate thermostat. HV2: 30%-75% Minimum Outdoor Air The HV2 option is required when the minimum outdoor air volume exceeds 30% of the total supply air volume. With higher outdoor air volumes, mixed air temperatures can vary greatly. Accordingly, 2-stage heating and/or cooling is recommended. Also, an airstream override thermostat is standard with HV2 to prevent cold air discharge (below 55. F) when the thermostat is satisfied. (electronic modulation is optional). TC1: 1-Stage Heating / Cooling TC1 is a coiled bimetal thermostat used for single-stage heating, cooling or heating-cooling systems. TC2: 2-Stage Heating TC2 is a coiled bimetal thermostat used for 2-stage heating systems. TC4: Programmable TC4 has full seven-day program capability. The thermostat can be set for four times and eight temperature settings each day of the week. It can control up to two stages of heating and two stages of cooling. TC5: Deluxe Programmable TC5 has full seven-day program capability. The thermostat can be set for two occupied and two unoccupied times with adjustable temperature settings for each day of the week. It can control up to three stages of heating and two stages of cooling. The Intelligent Fan™ feature energizes the fan continuously during occupied mode and intermittently with a call for heating or cooling in unoccupied mode. TC3: 2-Stage Heating / 2-Stage Cooling TC3 is a coiled bimetal thermostat used for 2-stage heating, cooling or heatingcooling systems. It includes an adjustable heat anticipator, stops, and a locking cover. Three heating and ventilating options are available to provide proper tempering and fulfill varying requirements for fresh outdoor air. In all cases, heating and cooling functions are controlled by a Greenheck room thermostat or a DDC system (by others). HV1: 0%-30% Minimum Outdoor Air HV1 is the most common among heating and ventilating units, allowing you to set the minimum outdoor air volume between 0 and 30% of the total supply air volume. With the relatively low percentage of outdoor air, mixed air temperatures are mild and stable. 1-stage heating and/or cooling is recommended. (2-stage or electronic modulation is optional). HV3: 100% Return Air The HV3 option is available when no outdoor air is needed. With relatively stable return air conditions, 1-stage heating and/or cooling is strongly recommended. (2-stage or electronic modulation is optional). Return Air Supply 70% - 100% Outdoor Air 0% - 30% Return Air Supply 25% - 100% Outdoor Air 30% - 75% Ret...
