DESTRATAIR
DESTRATIFICATION FANS
Because we know how difficult controlling the temperature in your building can be, we found the solution you were looking for!
GET A COMFORTABLE WORK ENVIRONMENT
Uneven temperatures and cold corners are a by product of stratification and inadequate air circulation. With DESTRATAIR we are able to recirculate the air, destratify the space and provide comfortable temperatures throughout the building. Your workers, employees and clients will enjoy the advantages which generally translate in an increase in productivity.
STOP LOSING HEAT THROUGH THE ROOF
It is known that the major loss of energy in a building is through the roof. That is why it is critical to direct the hot pool of trapped air at the ceiling down to the floor level where it is needed. DESTRATAIR creates a controlled airflow that constantly recirculates the air in the building to avoid heat loss through the roof and without any drafts at floor level!
START SAVING MONEY AND MAKING SIGNIFICANT ENERGY SAVINGS
To compensate for heat lost through the roof, your heating systems work overtime to try to maintain comfortable temperatures in the building. This quickly translates in high energy bills. With DESTRATAIR you can estimate conservative savings of 20% of direct heating costs and it also reduces the wear on existing HVAC systems.

WHAT IS STRATIFICATION?
When heated air is released into an enclosed space it has a natural tendency to stratify: hot air rises up and gets trapped at the ceiling while cooler air sinks toward the floor creating a temperature differential from floor to ceiling. Stratification can cause a 5°C to 20°C difference in the floor-to-ceiling temperature. Generally, the hotter the roof, the greater the heat loss from the building. Energy loss through the roof of the building in this way can substantially increase operating costs of the heating system. Also, uneven temperatures and cold corners that create uncomfortable working areas are a byproduct of stratification and inadequate air circulation. It has been found that stratification is the single biggest waste of energy in buildings today.
THE PROBLEM WITH CEILING FANS?
They only provide minimal destratification in a building. The fans are generally mounted 4 to 10 feet from the ceiling which does not allow for proper thermal equalization as the hottest air remains trapped above the fans. These systems are also known for having a costly installation, being generally noisy, causing drafts at floor level and it is complicated to reach them for maintenance.
HOW DESTRATAIR FIXES THE PROBLEM?
Destratification is the process of recirculating the heat accumulated at the roof to eliminate stratified layers and achieve temperature equalization. This allows substantial energy savings. Our destratification fans efficiently redirect the hot air that is trapped at the ceiling down to the floor level to provide equalized temperatures for complete destratification, thereby reducing the demand on your heating systems. They allow for significant energy savings and will provide more comfortable temperatures at floor level which generally translates in an increase in productivity.
ABOUT THE PRODUCT
DESTRATAIR can be integrated into any building regardless of the heating system, to minimize the floor to ceiling differential of temperature without the use of ductwork
The system designed utilizing DESTRATAIR as ‘the prime air mover‘ will reduce heat input requirements, generally maintain air stratification to within 1°C and provide for comfortable working conditions throughout the space.
Whereas most other destratification systems are calculated on the basis of approximately 1 to 2 air movements per hour, DESTRATAIR is calculated at a higher rate of between 2 and 4 air movements per hour. This is possible to achieve because the initial air velocity from the fan is forced away from working level and directed specifically towards the roof. Using the shape of the building, air is deflected off the roof to travel as far from the fan as possible. As air hits the roof it spreads out and slows down, but still has sufficient velocity to travel further, in most cases to the far side of the building. Throughout the process from the outset, air is being drawn into the fan assembly at a relatively low velocity, and within minutes from start-up, “air rotation” is achieved throughout the entire space. Every cubic foot of air within the space is involved in the gentle rotation, whereby it goes almost unnoticed at the floor level despite the accelerated upward velocity towards the roof.
The DESTRATAIR can be used with oil or gas-fired warm air heating systems, gas-fired radiant plaque heaters, overhead radiant tube and low temperature hot water panel heaters, wet systems, low temperature hot water unit heaters and most types of electric radiant, plaque and warm air heaters.
For most installations, the units should be mounted at a height of 8 – 10 feet above floor level. For taller buildings, or where wall space is taken for other purposes, the fans can be positioned lower or higher as the case dictates.

FAQs
Q. Why do I need destratification fans?
All space heating systems result in stratified air, making the roof hotter than the floor level. The higher the roof temperature, the greater the heat loss through that roof. If the roof temperature is reduced, less fuel is required to run the heating system also resulting in a more uniform building temperature. Fitting destratifcation fans will definitely reduce heat loss through the roof.
Q. I have radiant overhead heating, can destratification be beneficial?
Yes. Most manufacturers of overhead radiant heating systems infer that the radiant heaters only heat persons and objects below the radiant shield. In fact, the surface temperature of the static radiant tube can be as high as 710° Fahrenheit. This makes the air temperature above the shield very much higher than at low level, increasing heat loss through the roof. Under these conditions, destratification fans can be very beneficial.
Q. Do all destratification methods perform equally?
No, please refer to the STUDY performed regarding this matter. DESTRATAIR has proven by far to be the most effective energy saving system.
Q. Are there any organizations that can help financially, with destratification projects?
Yes, very often the gas or electricity suppliers offer incentives to install new energy efficient equipment. Destratification equipment is highly likely to feature in these offers.
Q. How would I know what destratification system would best suit my building?
All destratification systems have their use, but for specific advice, e-mail us the details of your building (length, width, height to eaves, height to apex), the shape of the space, how it is used, the layout (racking, benches, mezzanine floors), and type of heating/cooling system. We will call you with expert advice.
Q. What is the best location for destratification fans?
With fans installed at low level and with air being directed towards the roof, there are generally no air impingement problems and fan location becomes less critical.
Q. Are destratification fans 'noisy'?
DESTRATAIR fans are designed to be extremely quiet so as not to increase ambient noise levels.
Q. Are destratification fans 'drafty'?
With most fans fitted at high level, some drafts will be felt directly below the fan. With DESTRATAIR fans mounted at low level and blowing air towards the roof (thus away from the work space), very little noticeable drafts will be felt at the floor.
Q. Can destratification fans really save money on heating costs?
Yes. If installed and operated to the particular manufacturer’s recommendations, fuel-input savings will be achieved.
Q. Can the use of DESTRATAIR fans reduce installation costs?
Yes. When using DESTRATAIR:
(a) Low level access results in reduced maintenance costs.
(b) No requirement for high level access equipment.
(c) Fans are installed at low level making the installation simple and easy.
Q. Do destratification fans need to run continuously?
For best results in terms of comfort levels and fuel-input savings, the destratification process should be continuous during heating season. If fans start and stop at the demand of individual thermostats, temperatures at the working level will fluctuate noticeably, and the saving process will be intermittent.
Q. Do destratification fans require maintenance?
Yes. From time to time, any fan type should be checked for correct function, and cleaned as necessary. This might involve the use of mobile scaffold, or mechanical ‘scissor lifts’ for fans mounted at high level and can very often be disruptive to the working process. For DESTRATAIR fans mounted at low level, access is very much easier.
Q. What if I have a mezzanine floor, can destratification fans help air circulation below them?
With industrial ceiling fans mounted at high level it is very often difficult to move sufficient air under a mezzanine floor to be of benefit to workers, or, contribute to fuel-input savings. Through the “total air rotation” concept of the DESTRATAIR system, the entire air volume within the space is affected, therefore mezzanines pose no problem.
