Systems are used to increase the air flow rate which correspondingly increases the power output of many of today's turbines. The volumetric flow of most turbines is constant and therefore by increasing the mass flow, power increases in an inverse proportion to the temperature of the inlet air. Typically increases in the neighborhood of 15% can be achieved with a 20ºF reduction in inlet air temperature. The increased mass flow also decreases the rate of fuel consumption per MW produced.
MORE AIR = MORE POWER
FOG type Evaporation cooling systems have proven to be the most popular choice for inlet air cooling for many reasons. The low capital cost, installation and operating costs make it attractive for many turbine operating scenarios. This simple cooling method makes it ideal for turbines that operate continuously to those that only operate for a few hours a year for power reserves and peak deman periods.

Installing conventional air conditioning for a workplace can be prohibitively expensive, both in equipment and operating costs.
FOG systems are an inexpensive, cost effective solution to cooling and humidifying throughout the world. Using standard nozzle lines, a precision system can be designed for any works / warehouse facility. These systems are easy to install and maintain and come complete with a detailed manual. Optional humidity and temperature sensors are available, allowing the user to have complete control over the air temperature and humidity.
Our high-pressure FOG system generates water droplets of size 20 microns and less. These droplets are so small that they stay in the air and flash evaporate when they hit the heat. Evaporation causes cooling. We can guarantee a wet bulb temperature through out the year, irrespective of the ambient condition.
Just give us the dimensional details of the area & we will design a suitable system for your requirement.
Outdoor Cooling & Special Effects
Special Visual Effects
We are certain that our fog system solutions will far exceed your expectations. Nee Dee Lee fog systems offer artists and designers innovative and robust aesthetic possibilities to create living and moving pure water fog effects with an entirely assorted palette to design from. Fog can be used as a medium to modify the visual and tactile aspects of the ambient environment. Nee Dee Lee Fog adds dimension and impact to a design and it can be used to highlight other design elements.
On a hot summer day, outdoor air temperature can be cooled to the low twenties-even though the temperature normally would have soared into the forties. The Nee Dee Lee fog machine atomizes water into droplets so tiny they stay suspended in air. On hot days the droplets totally evaporate. This cools the surrounding air by as much as 20º. And fog cleans the air and eliminates smog and dust. Resorts, public parks and private residences use fog to cool patios, poolside, outdoor eating areas, tennis courts and even golf courses.
Nature is full of examples of sensational fog and cloud effects. For instance: light and wispy strands of morning mist on a calm lake, swirls and eddies of mystical low-lying ground fog, huge cumulus clouds building and rolling over a darkened prairie, thin fleecy streaks of high altitude cirrus clouds glowing pink in the afternoon sun, and thick and mysterious clumps of dense fog clinging to a rocky coast. All of these moods and so much more can be created with Nee Dee Lee Fog.
Animal Cooling Solution
Equestrian centers and Stud Farms, in hotter climates require our FOG SYSTEM to cool horses and riders. Systems can be used indoors and outdoors shielding horses from the adverse effects of direct sunlight, cooling and protecting the animals from flying insects and also suppressing dust. Keeping your horse cool and comfortable during the summer is absolutely vital. When high ambient temperatures and humidity combine, body heat may accumulate faster than your horse can get rid of it. The fact is, horses are better at keeping themselves warm than cooling themselves off.
FOG SYSTEM uses atomized water droplets to "Flash Cool" the hot, stale air in your barn or run-in shed. So it doesn't just move the hot air around, it cools and conditions it. That can help your horse avoid heat-related threats like hypothermia, muscle tremors or weakness.
In conclusion, fog systems will improve the overall physical condition for any animal related operation. They are great for cages, kennels, stables, barns, zoos and shelters. They will protect the animals from the adverse effects of extreme summer conditions. The systems will also repel flying insects and help minimize or eliminate dust and other airborne particles.
This improved quality of life can have a noticeable effect, especially when dealing with highly prized racehorses. By reducing temperatures, a typical hog farm will improve feeding cycles which directly increases the size and value of the animal
Fog Systems installed in barns humidify the air and keep animals in excellent physical condition. These systems can be installed in a variety of stalls, kennels and cages that house animals, including zoos and shelters. Our Fog systems are used in poultry cooling, as birds have no natural means of perspiration, chicken and turkey farms loose millions of dollars each year due to extreme heat waves that kill poultry.
Cooling Dairy Cows During Hot Weather
Other viable animal applications include the equestrian and hog industries. As with cattle and poultry, the main benefit is improved environmental conditions for the animals.
Animal cooling One of the more common uses for cooling with a Fog system has been in the cattle and poultry industries. In both cases, effective cooling systems can dramatically improve the overall operation. The flash evaporation achieved with a fog system cools without excessive moisture thereby eliminating infections and unsanitary conditions associated with other less effective cooling systems.
For cattle, the cooling system reduces heat stress providing improved physical metabolism. This equates to enhanced milk production, increased feed intake, better weight gain and faster reproduction. For poultry, the fog system will compensate for their own lack of a natural means of heat reduction. This helps eliminate premature aging and unnecessary losses in stock. Fog System also improves their physical metabolism leading to increased egg production.
Dairy and beef cattle are able to adapt to a wide range of environmental conditions. However, prolonged periods of high temperature alter metabolism and depress feed intake, milk production, weight gain and reproduction.
There have been many studies done that agree, utilizing a fogging system at the corral manager is effective and cost efficient. Cooling the cattle, produced a milk yield of 8% loss whereas the loss for non-cooled cows was 12% and beef cattle maintained their market weight. The fogging system is a perfect environmental choice, in comparison to sprinklers or sprays. The fog flash evaporates cooling the surrounding air without saturating the animals and leading to unsanitary conditions in pens and parlors.

Humidification For Maturation Warehouses To Eliminate Evaporative Losses
The typical wine storage area does not have adequate humidification. This results in wine losses, from the barrel storage areas, of 15% or more and also affects the quality of the finished wine.
Old style spinning disk type humidifier are often designed, based on their rated output but cannot actually be operated at full output without wetting the floor. This can result in an undersized humidification system and low humidities in the storage area. In anyway, these systems create Temperature and Humidity gradients and cannot achieve uniform Humidity. Humidity levels of 65% in a barrel storage area are low enough to result in wine losses of more than 15% per year. Air conditioning units actually remove moisture from the air and are the major cause of low humidity in storage area.
The FOG SYSTEM is a high-pressure water atomizing system, that breaks water down to droplets, that are in the 10-micron size range (that's about 1/10th the diameter of a single strand of human hair). These FOG droplets are so small that they remain airborne and fully evaporate in the air. This allows you to maintain up to 100% Relative Humidity without actually wetting things in the storage area. Thus, with the Relative Humidity matching vapour pressure within the barrels, the vapour migration occurring in mechanically cooled warehouse is substantially reduced. This reduces the need for topping off by at least half.
The secret is the FOG. The resultant FOG spreads inside areas as dictated by the spray nozzle placement. It cools and humidifies throughout the full range of its movement. The desired level of humidity is kept constant by aspirated dry bulb/wet bulb Humidistat controls. Thus temperature and humidity gradients are eliminated.
Spirit makers across the world using FOG SYSTEM have reported, that the savings paid for the system in less than a year.
The system delivers water droplets in the region of 10-30 microns, which is required to keep the humidity level at desired level and to eliminate evaporative losses.
The drop in temperature achieved due to the evaporative cooling also helps in reducing the evaporative losses.
A brief Calculation in support for the need to install FOG SYSTEM for HUMIDIFICATION:
A typical Barrel contains 200 Lts of spirit.
There is an evaporative loss of 15% annually, which comes to 30 Lts.
Taking Cost per lt of spirit as Rs. 100/-.
The loss comes to Rs. 3000 / barrel / year.
So, if there are 4500 barrels, there will be a total loss of Rs. 1,35,00,000/-per year.
Considering the cost of the Fog system and its running cost, the payback for the system is within first six months of its installation. And after that you start saving a very large substantial amount, every year, each year.
Spirit makers throughout the world have always suffered large losses in barrel rooms due to low humidity levels. The "New World" wines from the Americas and Australia have not had the benefit of large underground wine cellars with naturally high humidities. They have had to move to modern-day constructions and create artificial environments with humidity levels as low as 5%.
Spirits in barrel rooms can lose up to 15% volume per year due to fluctuations in humidity levels. "Topping-Off" is an exhausting and time-consuming process that can be reduced with our FOG humidification system. Oak barrels in use or in store suffer from the swings in humidity and can be damaged even before use.
We have specifically developed our humidification system for barrel rooms. Expertly designed, tailor-made systems are installed in the barrel room to accurately maintain the humidity around 85%. Nozzle lines are mounted in the house to give an equal distribution of the humidity. The system leaves no wetting of the floors or barrels when in operation and does not affect the stored wine.
The Fog system humidifies and cools the barrel room reducing losses to 1 or 2% per year, drastically reducing the labor involved in "Topping-Off".
The technology has been accepted and appreciated by one and all across the world.

Textile Humidfication - FOG SYSTEM
Humidification is rapidly gaining importance in many industries. The requirements of modern high-speed production techniques and increases in internal plant heat loads often result in the need for better control of humidity levels in the plant environment.
Other factors can affect humidity levels too: upgrading manufacturing equipment can lower the humidity in a plant because modern machines often generate more heat.
Many industries face stringent indoor air quality standards. Meeting these standards can often require bringing more outside air into the plant. If this outside air is dry or cold the result can be much lower indoor humidity levels.
Existing plant humidification systems are often incapable of meeting these increased demands. But adding More capacity to inherently inefficient humidification systems can be very costly.
Our Fog system is an effective alternative to traditional method s of humidification.
Fog System - humidification benefits
Increases tensile strength of natural fibers and reduces waste.
Improves product quality and increases production.
Reduces static electricity and personal shock is eliminated.
Yarn is more controllable and fiber discharge and fly settle time is shortened.
Helps control cotton fly and lint and reduces yarn separation.
Pre-cooling with FOG system
In extreme heat, many conventional air conditioners either shut down or fail due to excessive ambient loads on the condensing coil. Many engineers have attempted to solve this problem by spraying the coil with water only to find out that this causes calcification and deterioration of the coil. Calcification reduces the heat transfer efficiency and increases operating costs in a more moderate ambient temperature.
NDLE offers standard packages for industrial, commercial and private air conditioners to "pre-cool" the air without wetting the coil as it enters the unit through our FOG system. By utilizing this package the unit can operate more efficiently with an extended operating life. Tests have shown that when the NDLE FOG system is installed the EER (Energy Efficiency Rating) of the units can be reduced by up to 55%. The power usage (in kW) can also be reduced by up to 33% depending on the climatic conditions.
By coupling the FOG SYSTEM to temperature and humidity sensors, the system comes on when the a/c unit is under extra heavy ambient load. Experience has shown that the NDLE’s pre-cooling system is an energy saving device that can reduce electrical consumption and not damage the condenser coils.
Existing plant humidification systems are often incapable of meeting these increased demands. But adding more capacity to inherently inefficient humidification systems can be very costly.
Our Fog system is an effective alternative to traditional methods of humidification.
