What is Static Pressure? Heater Static pressure is defined as You cannot maintain proper “the pressure exerted by static pressure if have air leaks a still liquid or gas, especially water Most managers overlook the fact that or air.” This simply static pressure is affected by air relates to the leakage. Remember, you are trying occurrence of a to pull incoming air in through slight decrease in engineered openings, not pressure within a through random leaks in the building relative to building. Cold air entering outside air pressure through cracks, curtains, or when one or more inlets is heavier than the exhaust fans are inside warm air. If it does not turned on. It’s the Static Pressure Tools shoot into the room with force you feel when sufficient speed at ceiling Smoke Stick, Manometer, you open a door to a Wind Meter, Pressure Gauge height, this incoming cold air production unit and will immediately fall downward you feel resistance (sometimes along the sidewalls and endwalls, called a vacuum). If the door closes resulting in pigs being chilled. This is behind you, you have static pressure. why drafts of air often feel cooler in If it remains open or opens wider, you these areas of sub-standard ventilated have no negative static pressure. If you buildings. In buildings under proper see curtains flapping and not drawing static pressure, there will be fewer cold up tight to the bird wire, you do not spots, fewer dead air pockets, and no have static pressure. It is important to drafts at animal level. By keeping proper understand this concept because the static pressure - between 0.05” and
0.08” - you can achieve suitable air mixing because the proper velocity of air coming out of the ceiling inlets, 800 fpm, will give sufficient mixing between incoming and Continued on page 2

causing you to lose static pressure, which allows hot air to be sucked up into the attic. Hot air contains a lot of moisture and is very damaging to your building’s attic. The attic insulation soaks up the moisture causing it to deteriorate. Insulation that once was 6 inches deep is now much less with minimal R-value. Also, the hot air causes the steel to rust and shortens the life of your building rafters. If the steel plates on trusses are compromised enough, the building could actually collapse under heavy snow.

tempered air. Velocity that is too slow will allow the cold air to immediately fall into the pig space.
Wind has a negative effect on static pressure & your heating bill Wind is a powerful ventilation force that can provide tremendous hot weather ventilation benefit, but it also can be an enormous hindrance during the heating season. For example, a sidewall curtain with three 4-inch diameter holes, will allow about 40 cfm of infiltration air into the building when subjected to a 5 mph wind. If the situation persists for four months, an additional 80 gallons of propane would be needed to heat the air to an acceptable temperature.
Check Fan Belts Fan belts that lose tension are not running cost effectively. These should be checked regularly. You can lose 50% of fan capability with slipping belts.
Minimum Ventilation When it comes to operating any air inlet system during the cooler times of the
10 to 15 mph wind whirling around the building creates a vacuum in the attic
year, it is important to keep in mind that our primary objective is to maximize the amount of fresh air we bring in without causing excessive decreases in air temperature or excessive increases in fuel usage. Quite simply, the more air we can bring in without decreasing inside temperature, the fresher the air will be, and the better livestock will perform. Maintaining a higher static pressure (i.e., 0.08”) by reducing the inlet opening will help direct the cool incoming air to move across the ceiling. As the air moves across the ceiling it will mix with the warm air, heat up and then upon reaching the center of the building, gently move towards the floor. The air temperature at animal level might stay the same or possibly increase, resulting in even better air quality. Again, the goal is not to reduce fan runtime/electricity usage, but rather maximize the amount of time fans operate so we can maximize air quality and animal health.
FEATURED PRODUCT: Attic Airlock Traps Hot Air Before Entering Attic Airlock
Protect Your Building in Extreme Cold Weather with Attic Airlock Attic
Airlock Double L’s new patent pending Attic Airlock is proving to be tremendously successful in trapping hot air before it enters the attic. The Airlock is installed above eachInsulation of the Stop ceiling inlets and has proven to eliminate significant heat loss when used with actuated inlets. Because it takes a short period of time for the inlets to close and with some not closing all the way, a lot of Inlet hot air can escape into the attic. The Double L Attic Airlock creates an air chamber between the room and the attic, thus reducing condensation in the attic and increasing the life of the building. It also minimizes the chance of the inlets freezing Heater up in extreme cold weather. The Attic Airlock will pay for itself in a reasonable amount of time with fuel savings, even heat, and better producing pigs.

PATENT PENDING
TopJet Gravity Insulated Shutter with Counterweighted Louvers No Air Restrictions or Leakage Double L’s new TopJet Gravity Insulated Shutter minimizes air leakage and seals up tight with no cracks or spaces for air to come through. Its patent pending design has counterweight louver blades made of 3/4” insulated board encased in fiberglass with an R-value of approximately 6; whereas the standard shutter has no R-value. The counterweight louver blades are uniquely designed to open from the top, directing airflow up. When static pressure is created by ventilation fans, Double L’s TopJet Gravity Insulated Shutter blades automatically open to exhaust the air. When fans stop, the counterweight closes the louver blades. Multiple infrared tests have shown a 20+ degree difference between the TopJet Gravity Insulated Shutter and the standard shutter - providing great energy savings, safer environments for animals, and less buildup of moisture in buildings.

Minimum Ventilation
•
Minimum ventilation is the amount of air that needs to be supplied to the animals for maintaining proper air quality during winter months
•
With proper minimum ventilation you can achieve: • Maximum heating of incoming cold air before it reaches the floor level • Even distribution of fresh air throughout the building without causing drafts • Removal of carbon dioxide, ammonia, odors, and dust • Proper static pressure for prevention of heat and moisture build-up
• Without static pressure, it is harder to manage ventilation, resulting in wet floors and hot ceilings which cause rust and corrosion

Stir fans are important in your effort to reduce costs and improve the environment inside your buildings during summer and winter months. Stir Fans are used to minimize temperature difference and recirculate heat. The recycling of heat will reduce fuel costs and create a healthy environment for animals and workers. Another purpose of air circulation is to cool and control the environment to reduce heat stress on animals & keep production at maximum levels.

Airlock Thermal Comfort for Little Pigs in Cold Wean to No Finish Barn
Pig Mat Saves 36% of Pig’s Heat Loss Tests conducted by Double L show that producers using the 4’ x 6’ Wean-to-Finish Pig Welcome Mat can use 36% less energy to maintain the pig’s body temperature (105º F) versus a pig lying on a concrete floor. Two boxes, 12” x 12” x 12” high, were made using 1 1/2” thick insulation board, leaving the top and bottom of the box open. Lined with 3 mil plastic and filled with water, two identical heating probes were used to heat the water to 105º F. One box was placed on a concrete floor and the other box was placed on the 4’ x 6’ Welcome Mat on a concrete floor. When the temperature of the water reached 105º F, the usage of kilowatts to maintain that temperature in two boxes was documented during the winter months.
Heater
Concrete Floor vs. Warm & Dry Pig Mat
In a 17 hour span, the box on the plastic mat used 1.15 KwH while the box directly on the concrete used 1.8 KwH. Results showed that a pig lying on the 4’ x 6’ Wean-toFinish Welcome Mat used 36% less energy to maintain its body temperature (105º F) when compared to a pig lying on the concrete floor.

1 Day of Stress For Young Pig = 3 Extra Days on Finishing Floor
4872 Pig Welcome Mat with Handles Reduces Pig Stress, Keeps Pigs Dry, and Helps Prevent Feed Waste The 4872 4’x 6’ Wean-to-Finish Pig Mat’s unique design allows the pig to lay on the elevated surface to stay warm and dry while avoiding diseases. The 1 1/4” raised feed lip keeps feed on the mat, preventing it from passing through the slats. Made of high-density polyethylene, the mat is non-conductive and acts as a barrier between the pig and the cold floor. Pigs that are cold and chilled use the feed they eat to keep warm because they do not have any fat; consequently, they do not gain weight. The Double L 4872 4’ x 6’ Wean-to-Finish Pig Mat will help the pigs to stay warm, dry, and healthy. This, in turn, will reduce the amount of days on the finishing floor.

Great for creep feeding
Accommodates 50 pigs
The creep feed stays in the 1/8” deep oval indentations and prevents the pigs from moving it around and wasting the very expensive feed. This is a big advantage over smooth or biodegradable boards.

Thermal Comfort Proven Cost Effective The most critical time in a little pigs life is the first twenty-four hours after birth. Pigs born at the 102º warmth of the sow and coming into a farrowing room of 70º or less are very susceptible to heat loss. Chilled young pigs have reduced resistance to disease, are drowsy, and often fail to suckle properly. As a result, they run a higher risk of being laid on by the sow or never getting that good nursing start. Pigs have no fat to keep them warm. The only heat gain a pig has is through its feed intake. The greater the heat loss, the more feed it will take to offset that loss and produce gains. Maxima thermal comfort flooring provides a warmth factor that does not rob precious body heat from the
little pig. This allows the little pigs to turn the feed they eat into pounds and not into fuel to heat their bodies. This flooring is also very energy efficient. The temperature in the room can actually be turned down 5º and still maintain a comfortable environment for the little pigs. Before you purchase any flooring, lay your hand on it. If it feels warm to you, it will feel warm to your little pigs. Flooring that feels cool to the touch will sap body heat from the animals. This is why the combination system of Schonlau cast iron under the sow and Maxima polypropylene in creep area is recommended by many
Schonlau cast iron has been on the market for decades. It is the only cast iron in the world that is manufactured using the “open mold process”. There are no part lines because this process uses a one piece mold. Other molds consist of two pieces (a bottom and a top), which results in part lines with sharp edges. Independent German institutes confirm there is 6% less teat injuries compared to the competition. This is why Europe’s biggest companies use Schonlau. Schonlau cast iron slats have outperformed all other sow flooring on the market!
producers. Cast iron is cool for sow and Maxima is warm for little pigs.

Pig Tender, Sow Tough - Protecting the Milk Bar
What does it mean to save just one more pig per litter? Protect your investment with Double L’s combination flooring system Schonlau cast iron under the sow and Maxima polypropylene slats in the creep area. The cast iron is cool for the sow while it is uncomfortable for the little pigs so they are inclined to stay off of it and less likely to get crushed. Producers reported they save at least one pig per litter from a crush death, making the PS57 and the IVP57 Farrowing Floors very cost effective!
