PASSIVE DEHYDRATOR FAQS

BLANK
HOW TO REGENERATE THE DESICCANT PASSIVE DEHYDRATORS.

Both the RCD-1 and the RCD-2 passive dehydrators are bottles filled with desiccant, the RCD-1 with no moving parts, uses gas diffusion to dry the waveguide while the RCD-2 uses its one moving part (a check valve), temperature changes and barometric pressure to move the dry air into the waveguide.

To regenerate the desiccant, use needle nose pliers to remove the gray filter from the inside top of the bottle. If necessary, dry the filter. Save the filter for reinstallation. Empty the RCD–1 into a clean baking dish. Heat the desiccant in a convection oven at 350° F for at least 1 hour or until the silica gel granules turn dark blue. Cool to room temperature. Immediately thereafter, pour the desiccant into the RCD–1.

Reinstall the gray filter in the top of the RCD–1 bottle.

Reinstall the original cap while taking care not to disturb the adapter fitting. Use slip-joint pliers to securely tighten the cap since leakage will reduce the desiccant service life. Reinstall the RCD–1.

Reconnect the tubing between the RCD–1 to the waveguide or coax system.

Snow and ice falling from buildings

How to avoid Snow and ice falling from buildings.

Sheets of snow and ice falling and being blown off buildings are a major hazard that can cause damage to the structure, equipment, and possibly injure someone. Winter conditions have been accounted for in the building design process for a long time, but mostly in a way that only accounts for the weight of the snow and ice acumination and how it will affect the building’s structure. New technologies, innovations, and design trends are requiring that more attention be paid to the dangers of snow and ice when designing and maintaining a building.

Before energy conservation was a big concern buildings were basically large boxes with inefficient insolation that would leak phenomenal amounts of heat that would melt most of the snow and ice almost immediately. Most older building also had simpler designs with smooth walls, and a flat roof with a tall parapet on top to contain snow and ice accumulation so it can be safely drained away. The only real concern back then was how much snow weight could the structure hold, and there were building codes and regulations to account for this.

With advancements in technology, materials, and engineering, buildings are vastly more energy efficient, retaining almost all their heat which creates a colder exterior for snow and ice to accumulate on. Some of these new materials create smooth surfaces snow and ice can slide down in an uncontrolled way causing hazards below. These new materials also allow for more complex building designs, which can create areas where snow and ice can accumulate in unforeseen dangerous ways. These advancements in technologies, materials, and building designs have immense benefits, but also create new problems and hazards which need to be addressed.

The most cost-effective way to address these hazards is in the design phase of the building. There are microclimate professionals that can take data such as local historic weather conditions, surrounding buildings, the building’s airflow patterns, shadow patterns, along with other factors and help identify any potential environmental problems with a building’s design before it is built. These microclimate professionals can also recreate designs in test conditions to see how they perform. It is highly recommended to consult a microclimate professional when designing a building to address potential hazards before the building is built and more expensive fix must be made.

Older buildings will still need to address this problem as they are constantly being upgraded to be more efficient and new buildings being built around them impacting their microclimate. This is where a snow and ice melt system should be installed for safety. Snow and ice acumination that forms in new ways on a building can cause unforeseen consequences. Water can freeze between and behind structures, expanding and causing structural damage. Drainage paths can be overwhelmed in some areas, causing refreezing and accumulation. New areas can become shaded by new buildings in the area causing accumulation where there wasn’t before that needs to be addressed and properly removed. A snow and ice melt system can increase the safety and protection of a building by minimizing the amount of accumulation and keeping drainage paths clear.

Preventing snow and ice buildup is important for the safety of a buildings structure, equipment, and the safety of people below. Whether it is in the design process, or after it is built a building needs to be able to manage snow and ice effectively. Any building’s microclimate should be periodically checked and analyzed to identify and address any problems, especially when they can impact the safety of the people below.

Heat Trace and Hoppers

Many industries that use hoppers utilize heat trace to aid in material flow. Hoppers are elevated storage containers that contain and dispense granular materials. Commonly used in agriculture hoppers are also used in industries such as plastics, chemical, pharmaceutical, energy, and construction. Despite being used to hold and dispense different types of materials they all function the same way and face the same issues.

The main issues with hoppers focus on the material flow. These issues include aspects related to material sticking together or accumulating on the walls of the hopper. This is commonly caused by the particle structure of the material or the presence of moisture. There are many ways moisture can enter the system, these can be caused by environmental conditions or by water or chemicals being applied to the material in the process before being placed in the hopper.

Major environmental factors that can introduce moisture into the hopper material are temperature and humidity. One way to mitigate this is to install a heat trace system onto the hopper. This controls the temperature of the hopper and material avoiding drastic temperature differences which could cause condensation to form on the inside of the hopper.

The application of water or chemicals to the material or the hopper for dust prevention, cleaning or as a step in the production process add moisture to the material. Moisture such as this should be accounted for in the design and selection of a hopper system to insure proper flow. However, despite accounting for this added moisture in the system variable conditions can still cause flow problems. One major problem for hoppers with chemicals or water added is freezing. Material freezing in a hopper can cause the material to clump together or freeze to the walls, causing a blockage or flow problems. This can cause production to be shut down until the material can be thawed or it is manually cleared out. The presence of a heat trace system in these cases will avoid the freezing and allow the material to flow in a predictable manner, avoiding costly shutdowns or disruptions.

There are many pieces of equipment that can be added to a hopper system to aid in the material’s flow such as augers and vibration units, but to combat the effects of variable environmental impacts a heat trace system should be included.

Radiation Pattern Envelope

Satellite antennas radiate signal energy in distinct patterns that are reported as their radiation pattern envelope. These patterns consist of lobes which indicate the intensity of signal radiation radially on a horizontal plane emanating from the antenna. These patterns of signal strength are measured including both horizontal and vertical polarizations at three frequencies which represent the bottom, middle and top of the antenna’s band.

When the radiation signal strength is measured, a main lobe will indicate the main direction of the signal beam. This main lobe indicates the direction the signal will be effectively transmitted.  The size of the lobes representing the strength of the signal will decrease as they get further from the main beam. Side lobes appear as small surges in signal radiation adjacent to the main beam. These side lobes can result in unwanted signal noise which can also reduce the antenna’s carrier signal.

The signal capacity of an antenna can be determined by dividing its carrier signal strength by its signal noise. Better antennas produce a better signal by creating minimal side lobes which reduces signal noise and increases the signal capacity. Antennas of lesser quality which have larger side lobes which diminish the antenna’s signal capacity. There are however ways improve an antenna’s signal capacity.

There are two main approaches to increasing an antenna’s signal capacity, increasing the carrier signal strength by increasing the transmission power, or by decreasing the signal noise. Increasing an antenna’s transmission power seems like an obvious solution, but it comes with added energy costs, and might not be applicable due to increased interference, regulatory restraints, and infrastructure limitations. Another way to increase the signal strength is to install a larger antenna, but installing a larger antenna is expensive, requires more maintenance, power, and a larger infrastructure. When increasing signal strength is too costly or not applicable decreasing the signal noise is an option. Simply realigning the antenna creating a different link path can drastically improve an antenna’s signal capacity, this is a low-cost way to decrease signal noise. The best solution would be to purchase an antenna that produces small side lobes. These are higher quality antennas that produce less signal noise resulting in a more optimized signal capacity.

Consulting an antenna’s radiation pattern envelope is important for selecting the right antenna for an application and important in designing and installing a communications system. Antenna manufactures publish radiation pattern envelope information for their products and make them available for review. When selecting, designing, installing, optimizing or troubleshooting an antenna or communications system always consider the antenna’s signal capacity by reviewing its radiation pattern envelope.

Heat Trace with Plastic Pipes

Heat Trace with Plastic Pipes

Heat cable can be used on plastic pipes but the plastic’s durability and thermal properties must be considered. Plastic has approximately 125 times the thermal resistance than steel but is also more susceptible to damage from direct high temperatures. The key to heating plastic pipes is to use a lower temperature and distribute it as evenly as possible.

It is always a good idea to use a heat trace system with an automatic thermostat and control, but especially so when using heat trace on plastic pipe. An automatic heat trace control can monitor and maintain the system’s temperature, alarm for problems, and shut off the heat cable to prevent damage.

There is heat cable designed specifically for plastic pipes that is self-regulating and has limited wattage. Self-regulating heat cables have a conductive core between two bus wires that becomes more conductive when cold. This system increases the power to the cold spots and decreases it to the warmer areas, which provides a more even heat source.

The manufacture of the plastic pipe should be able to provide information as to the maximum temperature and how close heat cable can be spaced or wrapped on the pipe to avoid damage. Some applications may require heat cable to be applied to opposite sides of the pipe at a lower temperature to distribute the heat more evenly, avoiding one direct area of concentrates heat which may damage the pipe.

It is recommended to install a foil material between the pipe and the heat cable to avoid direct contact and help provide a more even heating. If doing this place the heat trace control thermostat directly onto the pipe with no foil over it or between it and the pipe to ensure a more accurate reading.

You can use heat cable on plastic pipes as long as you follow precautions, such as determining your pipe’s thermal capacities, selecting a self-regulating, low wattage heat cable and using an automatic heat trace control with safety functions. Following these guidelines will help prevent damage and increase the life of your heat trace system.
