Air Turnover

In a building with high ceilings, such as a warehouse or manufacturing facility, thermal barriers are established as warm air rises and gets trapped at the ceiling. The result, known as "air stratification," creates layers of temperature in the space.

The temperature at the ceiling may be 25 degrees hotter than at the floor, and the heat trapped at the higher level is unusable. Since the desired building temperature must be maintained at a low level, the inevitable result is excessive heating bills.

Air stratification also creates problems in spaces that require cooling. Because cool air settles to the floor, higher levels remain too warm. When the temperature is not uniform from floor to ceiling, condensation can form causing moisture damage.

An Air Turnover system solves the air stratification problem by continuously circulating the air in the space. It picks up air at the floor, removing the coldest air layer supporting the thermal barrier. The air is heated or cooled, and returned quietly through a screened discharge plenum to create a uniform temperature and a comfortable, more cost-effective conditioned space.

The Air Turnover principle eliminates air stratification in large open space buildings. It does this by recirculating the hot air which becomes trapped at the higher levels. The uniform room temperature improves comfort, conserves energy, eliminates thermal barriers, and reduces the possibility of condensation forming on stored materials.

Direct Fired

Flexible units for space heating, make-up air, and ventilation applications

When more air is exhausted from a building than is supplied by the mechanical systems, the building is under a "negative" condition and air will leak into the building through cracks, windows and doors. A negative condition results in the following:

- Flues and stacks will experience a backdraft and cause dangerous contaminants to remain in the occupied space. In the case of flues, the products of combustion may condense and corrode the equipment.
- The exhaust system sees a greater static pressure which reduces the capacity of each fan, resulting in an inadequate removal of contaminants and wasted horsepower.
- Drafts and cross currents will increase, causing an uncomfortable or unhealthy work environment.

Direct Firing eliminates the need for heat exchangers, resulting in 100% efficiency. All products of combustion are introduced into the supply air stream at concentrations well below code requirements. As natural gas is an abundant, clean and low cost fuel that is readily available, this system is very cost effective to operate.

Indirect Fired

Flexible units for space heating and make-up air applications

With Indirect Fired gas heating equipment, the burner flame is never introduced into the circulating air stream. All products of combustion are vented outdoors through the exhaust flue. As a result, in Indirect Fired equipment is ideal for Space Heating, Make-up air for applications where Direct Fired units are not allowed, and Heating and ventilating applications.

Applied Air manufactures Indirect Fired equipment with heat output from 250,000 BTUH to 6,000,000 BTUH, and air delivery from 3,500 CFM to 94,000 CFM.

Direct Evaporative Cooling

A business with a large space to cool can count on the direct evaporative cooling system. They are the efficient way to cool...at 1/5 the cost of mechanical air conditioning. The innovative evaporative cooling media provides simple and efficient evaporative cooling using water, not refrigerants. Water sumps and cooling sections are solid stainless steel. Units are AMCA certified.

Direct/Indirect Evaporative Cooling

Evaporative cooling is the most energy efficient and cost effective form of cooling that exists...and an indirect/direct system offers the closest performance to a DX system...but equipment cost is lower than a refrigeration system, installation is simple and inexpensive, and operating costs are a fraction of refrigeration systems. Evaporative cooling units are also environmentally friendly as they cool efficiently without the use of compressors or HFC refrigerants.

An evaporative cooling ventilation system provides fresh air to the building; forcing the hot, stale air out. These units provide maximum comfort when you need it the most. The hotter and drier the air, the greater the cooling effect.
The Indirect/Direct version also has a direct evaporative module downstream of the indirect section. This section will lower the dry bulb temperature even more while adding moisture to the airstream.
