• Total Heat Load combines building losses, infiltration, and equipment density.

• The ‘ramp up’ time is usually 4-6 hours. Typical rate is to elevate the building temperature, gradually (approx.) 10°F (6.0°C) per hour.

• ‘Cook’ temperature is 125°F (52°C) – 140°F (60°C) held for approx. 6-12 hours for thorough heat penetration into the walls and equipment.

• ‘Cool down’ time is usually 4-6 hours.• ‘Cook’ temperature controlled by throttling steam, NOT by

cycling fans. Maintain maximum air flow.

• 160°F (71°C) controlled discharge air temperature from the steam heaters

– Controls the building ‘ramp up’ rate to 10°F (6.0°C) per hour for structural integrity

– Prevents potential damage to electronics– 160°F (71°C) discharge temperatures will maintain ambient room

temperatures of 140°F (60°C) and 125°F (52°C) – 140°F (60°C) surface temperatures

– Local temperature control at each heater

• 100% recirculation of the building air (w/floor fans)– Lower energy requirement less than 25% of ‘ramp up’ design) during

‘cook’ cycle

Equipment Considerations• Equipment ‘density’ is an observation!• Determined by relative concentration of production

equipment/ducting/chutes/conveyors, tanks, silos, etc. relative to the space to be heat treated

• If exact, total equipment weights per sq. ft. of floor space are available, then use that, otherwise judge the space as– Light density– Medium density (Base when other data unknown)– Heavy density (AHTG programs will adjust for variation)
