Commercial / Residential Air-Conditioning - 

When talking about air-conditioning and removing moisture it is important to understand the difference between latent and sensible heat.  Let’s learn from the University of Florida cooperative Extension Service:A building air-conditioning system is responsible for removing moisture from the air in order to provide for both human comfort and mold- and mildew-control. Inside the air-conditioner warm moist air is blown through a cooling coil. In the coil the air is cooled below its dew point temperature--the dew point temperature is defined as "the temperature of the air when the relative humidity is 100%".  Relative humidity is defined as "the amount of moisture in the air relative to the most moisture the air can hold at the same temperature".  As air is cooled it loses its ability to hold moisture, so relative humidity is increased by cooling the air, as well as by adding moisture to it.  For example: as the air cools on a muggy night the relative humidity increases.  When the relative humidity reaches 100%, the air has been cooled to its dew point and dew forms on surfaces. Similarly for the air-conditioner, once the air is cooled below the dew point the air releases moisture ...which collects in a drain pan and drains out of the system. The cooled and dried air is delivered to the building. The air now has a lower dew point, called the "exit dew point".

​Many air-conditioning systems do not remove adequate amounts of moisture for Florida’s climate, as well as many other areas.  Most air-conditioning systems are designed to handle peak load conditions: i.e., the hottest afternoon of the summer.  Accordingly, they work best during the hottest times of the year but not so well at other times. AC systems are designed to remove a certain amount of moisture at peak conditions.  This is called the latent heat ratio of the system.  Sensible heat is the heat in terms of degrees one reads on a common thermometer.  Latent heat, the other kind of heat is heat in terms of moisture removed.  Sensible plus latent is the total heat removed.  The latent heat ratio of an air-conditioning system is the portion of latent heat it can remove.  It is typically around 30% at peak conditions (95 degrees F outdoors) and a few percent higher at night conditions (75 degrees F. outdoors). The building load also has a latent heat ratio.  It is the portion of latent heat that needs to be removed from the building.   At peak conditions there is much more sensible heat than latent heat.  At night and on cooler days the amount of sensible heat shrinks but the amount of latent heat does not; and on wet days the amount of latent heat grows.  The latent heat ratio may rise to 50% or more.  During humid and/or cool weather, the air-conditioning indeed cools the building, but it can’t dehumidify adequately.  

​To make things worse some new air-conditioning units have sacrificed latent (moisture removed) capacity in order to increase their nameplate SEER rating. (SEER stands for Seasonal Energy Efficiency Ratio and is a measure of energy efficiency).  One way manufactures increase SEER is to raise the cooling coil temperature. Unfortunately, this means the air blown through the coil does not reach a low dew point temperature.  Some of these high efficiency units have a latent heat ratio of 15% or less at design conditions.   Captain Cool Filters stabilize latent heat, improving the performance of the air-conditioning equipment.  By stabilizing humidity the filters allow the air conditioning unit to run more efficiently.  When humidity is stabilized, less energy is used to lower the temperature for cooling.  This saves you money any time your unit is cooling.

​Industrial - 

COOLER DOCKS: Cooler docks are only running when the shipping or receiving.  They are turned off during the off time. Therefore, when the unit is turned on, all the humidity that is in the cooler dock area has to pass thru the refrigeration system. This causes the compressor to work extremely hard and it takes much longer to reach set point temperature. Also the dock doors are opened and closed as trucks are unloaded and the dock curtains allow warm humid air to seep through; causing the compressor to fight the on slot of unconditioned air continuously. The cooler docks are always damp and mold forms fast because the units are turned off at shifts end. The Captain Cool Air filters will help eliminate the dampness and the mold as the filters will collect the humidity in large doses when the humidity is high and release it a little at a time as the unit reaches set point. The refrigeration system is much more efficient and will reach maximum temperature much faster, making the compressor run a lot less.

WAREHOUSE COOLER OR FREEZERS: They are heavily traveled areas for product selection and receiving areas. This means the cooler/freezer doors have to open and close throughout the work day. Some coolers/freezer have high speed doors with curtains, others have a pull chain cooler door and curtains, and the old ones have manuel with or without curtains. This means different door closing times if closed at all and poor air brake from the cooler curtains. When the door is opened the warm humid air rushes straight to the cooling coil, this causes the compressor to run extremely hard and longer to reach set point. Handling the rush of humidity and unconditioned air is the hardest and most inefficient part of a refrigeration system. During your daily activities selection and receiving, the door is opened and closed numerous times throughout the work day.The cooler continues to hold a high level of humidity and higher temps throughout the work day. This in turn causes the cooler to become damp. Water is formed and coats the cardboard cases or product. It also causes the floors and walls to become damp, which will lead to mold once the cooler door is closed for the evening. This same effect happens in freezers, only the water becomes ice and coats the cardboard cases or product. In the freezer you will see ice cycles or ice buildup around the units and selection racks, filters, and doors. The Captain Cool Air filter will help eliminate this. The key to efficiency in any refrigeration system is how much and how often unconditioned air is introduced into the conditioned area.  No matter what the circumstances the Captain Cool Air filter will drastically improve the efficiency and condition of the conditioned space.


Walk-In Coolers / Refrigerators -  

In the refrigeration industry Captain Cool Air filters equalize and stabilize the moisture in your refrigeration equipment.  It also absorbs contaminants and gases that pollute the air, as well as cause odors keeping your products fresher, crisper and the air cleaner.Captain Cool Air filters eliminate ethylene gas. Ethylene gas is an odorless, colorless gas, that is naturally produced by the ripening process, and accelerates the decay and ripening of your fruits and vegetables.

​By removing the excess moisture you will also prevent mold, mildew and bacterial growth. Captain Cool Air filter conditioners, when tested, showed a 5% amp draw loss, which equates to a 5% reduction in energy used.  This, in itself, will give you a payback in just one year, not including the money saved in previously lost products or any of the other benefits.  Don’t forget! The filter lasts year after year with precise performance, if properly maintained.  
Freezers - 

No ice or snow buildup on products or refrigeration equipment. It also eliminates freezer burn. Ice is nothing more than frozen moisture. With Captain Cool Air filters reducing the moisture and achieving lower dew points, your icing and snow problems are gone. You will achieve colder temperatures in your refrigeration or freezer unit, helping with efficiency and saving you money with reduced equipment run time. Captain Cool Air also reduces defrost cycles to save you money. Reduction of moisture also makes for safer working conditions better inspection reports.   

Residential - 

For years we have all used baking soda in our refrigerators to remove odors and keep our refrigerator fresh, but unfortunately it only helps with odors and you have to replace them every 3 months. Captain Cool Air bags and mats, on the other hand, not only remove odors but also stabilize the humidity in your refrigerator, remove ethylene and harmful gases and makes food last much longer. If properly maintained they will never wear out or lose efficiency!!! These awesome Zeolite blend bags and mats have a variety of uses. 

​If you want smells to be absorbed - not just masked or covered up - Captain Cool Air bags and mats are the answer. Put one in a dish in a problem area, like a drawer or closet. Odors will be eliminated, and you can then rejuvenate the product to use again and again. If you need to keep moisture away from sensitive items like guns, tackle boxes, or any moisture-sensitive item, you can use these bags and mats like the little silicon desiccant bags you get with new electronic equipment. Put one in your tool box or sewing kit, and keep your devices rust and corrosion free. The nice thing is you can always rejuvenate and reuse over and over again.


Captain Cool Air filters capitalize on the adsorption and absorption capabilities of Zeolite. Adsorption is when molecules, ions, and atoms are attached to a surface - holding or clinging on - when absorption involves the whole volume of the material, like a sponge. Zeolite will release water vapor but hold onto gases until the medium is rejuvenated (in this case, heated up and dried out). This is the MIRACLE of Zeolite: being able to absorb (trap) bad gases, but also adsorb water vapor and release it so the filter won’t maintain a significant weight gain. By restoring the filter this removes everything that the filter has absorbed, or trapped, making the filter like-new!! Make sure you look at Captain Cool Air zeolite filters as an investment that give you a return on investment: in less than a year, your investment will surely be paid off, and then Captain Cool Air will make you money for years to come. Don’t let this unique opportunity pass you by.
