De-Ice Systems for Satellite Antennas
Protect Your Signals from Ice and Snow - Original Hot Air De-Ice Systems
W.B. Walton Enterprises Inc. (Also known as Walton De-ice) designs and manufactures the broadest line of equipment available for preventing the accumulation of snow and/or ice on satellite earth station antennas.
The original De-Ice products designed by W.B. Walton Enterprises includes a behind the antenna plenum (enclosure) which is heated with hot air. These systems are for antennas ranging in size from 3.7-meter to 32-meters in diameter. While there have been many product refinements over the years, to make these systems more efficient, and easier to install, the same basic concept is still in use today. Walton De-ice offers several options for heating including; gas heaters with their economical operation advantages or Stainless Steel Electric Heaters.
Advantages
- Unique hot air Plenum (enclosure) design mounts behind reflector- from 3.7 to 32 meters.
- Most reliable and economical system on the market.
- Uniform surface heating minimizes distortion losses - unlike inferred electric heaters, electric pad, and heat tape anti-ice systems.
- Electric, natural gas, or liquid propane heater options to best fit your needs.
- Field-proven Ka-band electric and gas systems.
- Automatic heat and moisture monitoring and control system.
ADC-3000 & DP-9
The ADC-3000 Local and DP-9 Remote Unit are the latest generation of control system offers you the most up-to-date and cost-effective Antenna De-lce Control System in the Industry.
Stainless Steel Electric Heaters
Maintenance Free Heaters
Key Features
- Stainless Steel Housing
- Stainless Steel Fins
- Totally Enclosed Fan Cooled (T.E.F.C.) Motor
- V-Seal Technology for battling the elements
- Technical Support available 24 hours a day / 7 days a week.
The Forced Air Electric heaters used on the Walton Hot Air De-icing Systems are built specifically for Antenna De-icing Systems. The Heating units are built to Walton’s demanding specifications in order to provide reliable operation over a long period time and under difficult climatic conditions. The heater (including the heater element’s fins) is made of Stainless Steel, and all hardware is either stainless steel or aluminum, for a rust and corrosion free life.
These heaters also incorporate the latest innovation with V-seal technology. Because these heaters are inactive for long periods of time, while also being exposed to the elements, preventing moisture absorption is paramount for long trouble free heater service. V-Seal Technology does just that, extending the life of the heater elements and improves their reliability.
The fan motors are totally enclosed fan cooled (T.E.F.C.) motors, which are better suited for this type of outdoor operation than open winding type motors. These heaters also incorporate built in thermal devices, which provide high heat protection.
Gas Heater for 3.7 to 32-meter antennas
Experience the Walton De-Ice difference
W. B. Walton Enterprises, Inc. manufactures a Gas Heater which is designed specifically for De-icing Satellite Earth Station Antennas. These Heaters are suspended from the antenna mounting structure and provide economical and reliable service for years to come.
The original De-icing system includes a behind the antenna plenum (enclosure) which is heated with hot air from either liquid propane, natural gas or electric heating units. These systems are for antennas ranging in size from 3.7-meter to 32-meters in diameter. This is the original de-icing system originated over 40 years ago.
Dual Hot Surface Ignition System
- Dual hot surface igniter's means redundancy in the ignition sequence.
- Large flame sensing rod. Turbulence no longer a factor during ignition sequence.
- Same reliable 3 try ignition sequence with purge time.
- No more pilot assembly or pilot orifice.
- Stainless Steel Burner greatly reducing maintenance costs and increases reliability.
Positive Blower Recognition for Ignition Sequence
- Normally open contact on air flow switch operates power to the ignition unit. No air flow, no ignition.
- If no airflow is verified, the ignition unit will not be energized and the unit will go into ignition failure mode.
Same Wiring and Mounting Configuration as Original Heaters
- Older Gas Heaters can be changed out with the new designed Gas Heating Units.
- Mounting and wiring is the same.
New Evolutions in Direct Fired Gas Heaters
Both Snow Shield Cover De-Icing Systems and the Gas Heaters for Plenum De-Icing now meet the European Union Declaration of Conformity for directives:
EN 60204-1:2006+A1:2009,
EN 60529:1991+A1:2000/IEC 60529:1989+A11999 and
EN12669 (EN298:2003 EN126:2004 EN1854:2006)
EU Gas Appliance Directive Test Standards: 2009/142/EC (GAD)
EU Low Voltage Directive Test Standards: 2006/95EC
Environmental Tests: EN 60529:1991+A1:2000
Feed Horn Rain Diversion, Feed Horn, and Sub-reflector
Feed Horn and Sub-Reflector
The Walton De-ice Feed Horn and Sub-reflector De-Icing System utilize the existing heated air within the plenum. The air is ducted to the Feed Horn and Sub-reflector using a 60 CFM Regenerative Blower that can operate at 110 VAC or 230 VAC single phase 50/60 Hz. the system can also be used as a Rain Diverter System to keep the Feed Horn window clear of any moisture.
Key Features
- The Regenerative Blower Assembly is CE Compliant
- Totally Enclosed Fan Cooled (T.E.F.C.) Capacitor Started Motor is Half Horsepower
- Motor Permanently Sealed Bearings and is rated for continuous duty
- Cast Aluminum Blower Housing, Impeller, and Cover
- Inlet and Outlet Internal Muffling
- Quiet Operation Within OSHA Standards
- Class F Motor Insulation Rated for 140 Degrees C. (284 degrees F.)
