Hapco electric heat gun ht-71002
I hav these new in the Box Hapco electric heat guns model # is HT-71002 Specs are as follows. HAPCO HT71002 MIL-STD-810E Features The Hapco HT71002 hot air tool is designed to operate in a potentially hazardous / explosive environment as spelled out in MIL-STD-810E. Method 511.3, Procedure 1. This devise produces hot air at temperatures up to 975 degrees F, utilizing compressed air / nitrogen passing through a high resistance electric heat element and it directed or diffused through various types of special purpose nozzle attachments. general info Some examples of applications are: Heat-shrinkable tubing, solder sleeve electrical connectors, drying and curing applications. The unit comes packaged in a fiberglass / aluminum carrying case and consists of two major parts: Control Unit and Heat Pistol. Control Unit The control unit contains the necessary electrical components to develop the principal operation voltage, switching and control logic. Logic voltage is 12 vdc. Contained in the control unit is the pneumatic regulation and filtration assemblies. By virtue of the heat tool requiring a moisture and contaminant free air supply, a two-stage filter system is employed, with the final stage at 6 microns. Each filter employs an automatic moisture relief valve, which activates each time air / nitrogen is connected to the control unit. The control unit also employs a high mass, low pressure sensing valve which shuts down the unit in the event air supply is cut off or interrupted and is electrically interlocked in an event the unit senses a loss of airflow or if the airflow would fall below 3.5 psi or >.7 scfm, the unit shuts down. These normally sell for $3800.00 Even if the airflow is re-established, the power on switch must be reactivated to return the tool to operation, this feature is especially beneficial in hazardous areas. All electrical components in the control unit are sealed to eliminate the possibility of electrical arching.

All electrical components in the control unit are sealed to eliminate the possibility of electrical arching. Input operating air pressure range is 60 150 psi. Operational Voltage: 115 vac, 10 amps, 50 400 hz. heat pistol The heat pistol is a self-contained ruggedized unit which is comprised of: a high impact housing, encapsulated thermal control electronics, power supply for the pistol, a high resistance electric heat element and is graduated vernier temperature range control ambient to approximately 950 degrees F. The operator need not return to the control unit to make temperature adjustments.In addition to the safety airflow interlock in the control unit, the pistol incorporates two additional safety features to protect the heating element: A sealed klixon, which shuts down the tool in the event of over-temperature. A photocell, which monitors the brightness of the element to control temperature linearity and also shuts down the tool if the photocell detects the element, is too bright. This could occur in the event the air / nitrogen supply is interrupted, cut off or the air supply line has become obstructed. These features are a back up to the airflow sensor in the control unit. If the heating element should require replacement, there are four (4) screws to remove, then unplugging the element and reversing the procedure for re-installation. The replacement of the element can be done in the field eliminating returning the unit for repairs and no interruption of work in progress. The heat pistol supplied operational voltage (115 vac, 50-400 hz) via the interconnecting air tube from the control unit. The HT71002 is also available at 220 vac, 50-400 hz.
