The HCS9000-FL and HCS9200-FL Flightline Hot Bonders (hazardous environment) are based on the standard HCS9OOOA Single Zone and HCS9200 Dual Zone units. Basic features, operation and capability are identical. They are further designed to meet the requirements of Class I, Division II, hazardous environment operation per the U. S. National Electric Code, as promulgated by the National Fire Protection Association.

Added features for flightline/hazardous environment operation are as follows:

  • The case has controlled pressurization and purging to eliminate any possibility of internal explosive vapors. An external air source is required for this function. The same air source is also used for the hot bonder's vacuum system.

  • The purge cycle is started by turning on the power switch, while plant air is connected. Once the case is pressurized and purged, the unit is ready for operation. Lighted indicators on the faceplate show case pressure status, purge cycle initiation, and when the system is ready.

  • Input and output power connectors are manufactured specifically for use in hazardous environments. The connector requires two separate motions to disconnect. The first turn of the locking ring allows the electrical connections to separate, while retaining the connector body captive. At this point, any arc that occurs is contained, not allowing any external vapor ignition. The second turn of the locking ring frees the connector from the receptacle.

  • A Ground Fault Interrupter (GFI) minimizes chance of electrical shock. Leakage of more than 4 milliamps of current to ground trips the GFI, cutting off all power.

  • An independent high limit controller is used with special "supervisory" heat blankets. The high limit controller connects to a temperature sensing circuit embedded in the heat blanket. If the blanket sensor detects any hot area exceeding 80% of the flash point of aviation jet fuel, the controller will disable power output to the blanket. The circuit is self-resetting when the temperature falls below the critical level. An indicator and alarm will alert the operator to the condition.
