Snow and ice falling from buildings

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...

Heat Trace and Hoppers

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,...

Radiation Pattern Envelope

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....

Heat Trace with Plastic Pipes

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...

Snow and Ice melt Environmental Impacts

Snow and Ice melt Environmental Impacts

Considering environmental impacts of snow and ice melt maintenance. There are environmental costs involved with any snow and ice melt system, knowing and assessing these environmental costs can help you choose the snow and Ice maintenance system that will...

Desiccant vs Membrane Dehydration

Desiccant vs Membrane Dehydration

Desiccant vs Membrane Dehydration. Two of the main types of dehydrators are used for waveguide dehydrators, desiccant dryers, and membrane dehydrators. Both effectively remove moisture from the air but do it in vastly different ways. A waveguide is a tube-like...

Leak rates and duty cycles of dehydrators

Leak rates and duty cycles of dehydrators

Understanding the leak rates and duty cycles of dehydrators The overall purpose of the dehydrator is to eliminate moisture in the waveguide of the transmitter. Moisture will affect the reflected energy and increase the Standing Wave Ratio (SWR) of the system....

Heat-Trace in Hot Water Maintenance

Heat-Trace in Hot Water Maintenance

Heat-trace is used in many aspects of everyday modern life that mostly goes unnoticed. One main example of this is the ability to access hot water quickly from any faucet in a large building no matter how far from the water heater it is. This is a function of a...

Power Line Noise Issues with Ground Fault Protection Equipment

Power Line Noise Issues with Ground Fault Protection Equipment

Due to the high sensitivity of ground-fault-current detection circuits, it is possible that excessive line noise on the power source wiring can cause an alarm. This can occur in the form of a ground-fault alarm, a stuck-relay alarm, or a ground-fault circuit alarm....

New line of Heat-Trace controls

This past July Environmental Technology released its new line of microprocessor-based heat-trace controls, replacing its already successful SST line which has been a trusted industry standard since 2011. The new GPT and FPT heat-trace controls were created with input...

How do I set up my GPT for a RTD sensor?

The GPT unit comes with a thermistor (two thermistors with the GPT 230) but is also compatible a 2-, 3-, or 4-wire RTD sensor. The diagram illustrates the correct wiring and DIP switch configuration for each temperature sensor wiring scheme. It is important that you...

Difference between 277 single phase and 277/480 3 phase unit?

The difference is the step down transformer that provides the power for the internal circuitry. On the 277 single phase the transformer is 277 VAC to 24 VAC and you will note that its primary winding is connected to the top and middle poles on the contactor. On the...
