- Lightning and EMI resistant
- Low cost
- Simple installation
- Single or 3-phase power control
An antenna ice melting system employs the CIT-XTV aerial sensor located adjacent to the transmitting antenna. Normally located in the transmitter shelter building and within 2,000 feet of the sensor, an APS-3C, APS-4C or EUR-5A snow/ice melting control interfaces the sensor with the heater(s). The sensor employs special filters and circuit design techniques to minimize susceptibility to EMI and lightning damage.
When using the CIT-XTV sensor, heaters operate at 38°F (3.3°C) during precipitation and for the hold-on timer interval, from 0-10 hours. The CIT-XTV sensor prevents heater operation at temperatures below 0°F (−17.8°C) to save electrical energy and to prevent partial ice melting. Heaters operate for the hold-on time as temperature increases above 0°F (-17.8°C) if precipitation occurred during lock-out.
The APS-3B and APS-4 control panels interface the sensor with the integral power control contactor. The EUR-5A control interfaces the sensor with a customer supplied power control contactor in the customers equipment panel. The control provides status indicators, adjustable heater hold-on timer, and bypass switch.
The CIT-XTV operated from customer supplied 24VAC unrectified or from a power supply purchased separately from Environmental Technology. The power supplies are available at either 120 VAC or 208-240 VAC.
