5. HEATING SYSTEMS
The body shall have a dry radiant heat chamber heated by 2 each 150,000 BTU retort tube propane burners with vertical exhaust stacks. Exhaust stacks have an automatic electronic dampener that opens when burners are fired and close when burners shut off to prevent heat loss. The burners are thermostat controlled and regulated at 10 PSI. The ignition system is 12 volt DC with electronic ignitor. Gas burner has a safety shut-off on loss of flame or excessive temperature. Automatic safety shut-off when diesel pump is operating. Burner has two stages, ignites on 5 oz. pressure, operates at 10 PSI, on high burn regulated by the same thermostat as the electric heater. Thermostats will be 0/300° F. solid state.

6. ELECTRONIC CONTROLS
All electronic controls will be solid state shock resistant. Thermostat for tack oil tank is 50/200°F. Thermostat for asphalt aggregate hopper is 0/300° F. Thermostat for the asphalt hopper has built in high limit safety shut down switch. Same thermostat controls the 12 volt LP Gas fired system and the 220 volt electric heating system.

7. EMULSION OIL TANK CAPACITY AND HEATING SYSTEM
For capacity, refer to list of models available. The tank has a double steel jacket with 2" insulation. The tank is equipped with a heat transfer system with an adjustable temperature valve that is capable of heating the emulsion oil from 0 to 150° F., using the truck engine coolant system as the heat source. The emulsion pump and all lines are in an insulated heated area. The tank has 220 volt thermostat controlled NEMA explosion proof dry well electric heater and a hot well for storing the spray wand in cold weather. Tank has an 8" fill spout and a 2" gate valve on tank drain. For ease of maintenance or change out of heater, tank does not have to be drained.

8. ELECTRIC HEATING SYSTEM
The asphalt aggregate hopper and liquid asphalt oil tank is heated by a 220 volt, 62 kw OSHA required NEMA explosion proof dry well electric heater, thermostat controlled with 25’ of cord with dual in-line 30 amp fuses with MOV 220 VAC surge absorber. The heating system is capable of maintaining heated material up to 300° F. during non-working hours.

9. FUEL
Optional 35 or 50 gallon frame mounted LP gas bottle with quick fill connector, 10 psi regulator and fuel sight gauge OR Optional 100 lb (25 gallon) removable propane bottle, complete with 10 PSI regulator.

10. TEMPERATURE GAUGES
The unit has two 3" dial type, stainless steel temperature gauges that constantly monitor the temperature of the asphalt hopper and road oil tank.

11. HAND TORCH
For drying off repair site and cleaning hand tools, the unit has a 200,000 propane BTU hand torch with shut-off valve and 10’ of hose with hose rack. Hand torch has mounting bracket for transport.

12. LIQUID ASPHALT OIL PUMP
A hydraulically driven, 1 1/2" self priming, variable speed, reversible, rotary gear pump with relief valve. Operating at 20 GPM at 1200 RPM, 100 PSI. The emulsion pump and all oil lines are in an insulated heated area.  The pump will circulate the emulsion oil to prevent separation and to crush any lumps that may form and cause clogging of the spray tip.  Air injection systems do not have this capability.

13. PAVEMENT BREAKER
We offer optional; Stanley BR45, 67 and 87 Pavement Breakers, complete with quick couplers, asphalt cutter, tamper and detachable shank with lockable transporting bracket.

The valve has an internal or external safety design will protect the operator and not allow the screw conveyor or asphalt agitator to operate when the doors are open. This system is designed to divert hydraulic oil pressure back to the tank. Electronic solenoids on hydraulic valve are not acceptable due to mechanical override feature and ease of bypassing system. The valve is operated from the rear of machine by remote levers. To reduce maintenance problems the main directional control valve stack has no electric solenoids.

20. SCREW CONVEYOR
10’ long by 6" diameter progressive screw conveyor has hard surfaced flights welded continuously on 2" scheduled 80 pipe and is ball bearing mounted. Conveyor is driven by a 9200 in.lb. torque variable speed hydraulic motor with forward and reverse. Shall have a delivery chute with 120° of pivot. All bearings can be greased from ground level.

21. ASPHALT AGITATOR
