The Air Turnover principle eliminates air stratification in large openspace buildings. It does this by recirculating the hot air which becomestrapped at the higher levels. The uniform room temperature improvescomfort, conserves energy, eliminates thermal barriers, and eliminatesthe possibility of condensation forming on stored materials.
In the heating mode:
The Air Turnover System picks up the air at the floor, where it is thecoolest, then heats and returns it to the space above. Innovative lowvelocity, low horsepower propeller fans gently turn over the room air1 to 3 times each hour to maintain uniform temperatures from floorto ceiling throughout the building.
Cold air from open doors inshipping and receiving areasbecomes less of a problem withan Air Turnover unit. Temperaturerecovery is almost instantaneousafter the doors are closed.
In the cooling mode:
The Air Turnover System picks upair at the floor then cools andreturns it to the space above. Acomfort zone is created from theunit discharge down to the floorlevel. For buildings requiring coolingfrom floor to ceiling, extensionsare available to get the unitdischarge to required height.The centrifugal fans quietly movelarge volumes of air, turning overthe air in the comfort zone 3.5 to5 times each hour.
AIR TURNOVERSYSTEMS
Air Turnover systems are unique floormounted heating and cooling units.
• Fuel is conserved by utilizing
heat normally trapped at
the ceiling.
• Electrical operating costs can
be reduced as much as 40%
with low horsepower, high
efficiency propeller fans.
• Quiet, warm weather ventilation
is available with low power
consumption.
• Condensation that might form
on stored materials is eliminated.
• Moisture damage is minimized
through constant air circulation
and uniform room temperature.
• Installation cost is low because
no duct distribution system is
needed. The availability of large
units also means fewer fuel and
vent connections.
• Easy to reach controls and burner
on floor mounted equipment
simplify maintenance.
• Flame safeguard reliability
provides safe operation.
Electronic programming control
monitors the firing sequence.
• Temperature recovery is rapid.
The cold air effect from open
shipping and receiving area
doors is quickly overcome
after doors are closed.

Air Turnover Heating Systems
Low Velocity DischargeIn heating mode, air isdischarged directly at lowvelocity. No ductwork isrequired so installed costis lower.

Air Turnover systems are unique heating unitsdesigned for installation at floor level directlyin the conditioned space of warehouses,manufacturing areas, shipping/receivingareas, and other large rooms with high ceilings.
An Air Turnover system works by continuouslycirculating large volumes of room air at lowvelocity. Quiet, energy-efficient propeller fans
turn over the room air1 to 3 times each hour,
thoroughly mixingthe air to maintain
a uniform temperature from floor to ceilingwithout drafts. Fuel is conserved by “reclaiming”heat that otherwise would be trapped at theceiling. Continuously circulating air helpsquickly overcome the cold air effect fromopen doors in the shipping and receiving areaafter the doors are closed. Unlike most indirectfired systems which replace exhaust air withwarmed outside air, an Air Turnover systemgenerally uses little if any outside air. As aresult, operating costs are very low.
Applied Air offers three styles of heating-onlyAir Turnover systems:
• Straight gas fired (IFP)
• Non gas fired “slave” (IFS)
• Gas fired for small spaces (IFJ)
Induced DraftDirect drive induceddraft fan on IFP helpsprovide gas heatingefficiency of up to 80%.
Control CabinetFuses and power trans-former are provided forsingle point electricalconnection.
Air Turnover systems from Applied Air create uniform temperaturethroughout the conditioned space. The result is greater comfortfor people in the room and significant savings on heating andcooling costs.
For Smaller SpacesTo meet the special needs of smallerwarehouses and manufacturing areas,Applied Air offers the IFJ for heatingonly or heating/cooling applications.The IFJ provides all of the advantagesof our larger Air Turnover systems ina more compact unit.

Air Turnover systems are also available thatcombine indirect fired gas heating and cooling.In cooling mode, these Air Turnover systemscirculate room air to create a thermal barrierabove the unit discharge. This thermal barrieracts as an insulating blanket between the hotroof above and the comfort zone below.Quiet, energy efficient centrifugal fans movelarge volumes of air, turning over room air3.5 to 5 times each hour.
For buildings that require cooling from floorto ceiling, extensions are available that raisethe unit discharge to the required height.
Applied Air offers two styles of heating/coolingAir Turnover systems:
• Gas fired with cooling coil (IFA)
• Gas fired with cooling coil for smallspaces (IFJ)
In Heating Mode
For heating, the Air Turnover systempicks up air at the floor (where it iscoolest), then heats it and returns itto the space above. Room air turns over1 to 3 times each hour. The result is acomfortable, uniform room temperaturefrom floor to ceiling.
In Cooling Mode
For cooling, the Air Turnover systemcontinuously recirculates large volumesof air to eliminate the room’s thermalbarrier. The result is a “comfort zone”from the unit discharge down to thefloor level. Extending the height of thedischarge increases the height of thecomfort zone. Air in the comfort zoneturns over 3.5 to 5 times each hour.
How Air TurnoverSystems Work
The Air TurnoverConceptIn a building with high ceilings, such as a warehouse ormanufacturing facility, thermal barriers are established aswarm air rises and gets trapped at the ceiling. The result,known as “air stratification,” creates layers of temperaturein the space.
The temperature at the ceiling may be 25 degrees hotterthan at the floor, and the heat trapped at the higher levelis unusable. Since the desired building temperature must bemaintained at a low level, the inevitable result is excessiveheating bills.
Air stratification also creates problems in spaces that requirecooling. Because cool air settles to the floor, higher levelsremain too warm. When the temperature is not uniformfrom floor to ceiling, condensation can form causingmoisture damage.
An Air Turnover system solves the air stratification problemby continuously circulating the air in the space. It picks upair at the floor, removing the coldest air layer supporting thethermal barrier. The air is heated or cooled, and returnedquietly through a screened discharge plenum to create auniform temperature – and a comfortable, more cost-effectiveconditioned space.
Key Benefits:
• Systems for heating only or heating/cooling
• All systems also provide quiet, warm weather ventilation
• Heating and cooling costs reduced up to 40%
• Quiet, draft-free operation with low power consumption
• No duct distribution system reduces installed cost
• Large and small units to meet every need
• Condensation and moisture damage eliminated
• Floor mounted controls and burner simplify maintenance
Using the advanced computersimulation technique called“Computational Fluid Dynamics”(CFD), Applied Air can prove floorto ceiling temperature differences ofonly 2.49 degrees in a 24-foot highspace with Air Turnover.
