Tomorrow’s Thoughts Today
Manufactured to rapidly and effectively melt and maintain granular or block material. Available in your choice of Propane or Diesel fired engines burner systems and Air or Oil Jacketed fabricated design.
MEGA Series Kettles are cylindrical shaped to conserve space while providing superior melting performance. They are manufactured with accessible hardware components for ease of preventative maintenance and repair.
All Kettles are constructed of heavy gauge steel. The agitation shaft is firmly suspended in tank; with variable speed control and reversible action providing optimum agitation efficiency. The agitator blades are engineered to evenly blend the molten material, with complete bottom and side wiping action, preventing material build-up while maximizing circulation.
See below for pictures, specs and more information about BASE’s Propane or Diesel Fired Melting Kettles.
At BASE, we continue to develope and improve current products along with developing new units that will aid in expanding the highway marking industry.
We hope you will contact us should you need additional information regarding any equipment products.
It is the intent of these specifications to describe the minimum requirements for a bottom diesel or propane fired, oil jacketed thermoplastic material heating kettle, suitable for preheating material to be applied by thermoplastic applicators.

The unit shall be capable of melting two-thirds of its material capacity to a temperature exceeding 400 degrees F within 75 minutes of initial heating and shall be capable of continuously melting material while traveling.
ank shall be a vertically mounted, cylindrical barrel-shaped container with a 32” to 34” maximum interior diameter with 3/16 inch thick walls and 3/8 inch thick bottom. The tank walls shall be oil jacketed. The exterior tank walls shall be 1/8 inch thick with a 3/8 inch thick bottom and form a cavity having a minimum spacing of 1 inch between vertical walls and 3 inches between bottom plates, which shall be filled with high temperature heat transfer oil. Heating oil for the oil jacketed kettles shall be manufacture’s standard. This oil jacket shall not be under pressure.
Shell: Shall be of 11 Ga. HR. Steel unitized construction to maximize heat efficiency and conform to the National Fire Protection Association Code 58. The interior side of the insulation shall have 14 GA. HR. which shall surround the heating tank directing the exhaust heat against the material heating tank and away from insulation, to assure even heating. There shall be a 3” NPT coupling/plug “View Port” through skin into combustion chamber for inspection of diesel fuel ignition system and combustion.
Expanded heat vapor shall be exhausted through two 11-gauge rectangular (3”X12”) stacks located 180 degrees opposite each other. Exhaust stacks shall rise at least 12” to 18” above kettles. One 2 inch square flash tube shall be located behind feed door, designed to exhaust fumes above operator head with a water-proof door that closes and opens automatically.
Shall be water-proof and constructed at a 30 degree slope enabling user to securely insert material without loss of product or danger of molten slippage. Its volume opening shall be 121 square inches. The kettle shall be capable of accepting either block or granulated thermoplastic material.
A 3” knife gate type material valve with trough shall rapidly discharge and securely close without the need for auxiliary heating.
Oil and material temperature gauges shall be visible at the discharge valve end of the kettle, with readings up to 550 degrees F.
The entire ¼” thick top HR. plate of the preheating kettle shall be divided into two removable sections.
Top hoist rings or metal platform shall be provided.
Solid heat protection panels 11 gauge thick shall be secured to the feed side of the kettle. The panels shall be constructed to have a 1 inch air flow space and shall have a 33 inch width dimension and cover from the top edge of the kettle to approximately 24 inches from the floor. Heat shields shall be mounted around the exhaust stacks.
Shall be durably attached to the discharge side of the kettle.
Upper and lower paddles shall be mounted on a 1 ½ inch diameter shaft and connected with two vertical blades ½ inch thick wiping within ¼” inch of tank wall. The aforesaid paddles and a center paddle shall be positioned to gently blend material homogeneously. The shaft and agitator shall be easily removable from the melting kettle to facilitate cleaning. The shaft support mounts shall only be located above the top plate of the kettle. The agitator shall be driven by one hydraulic motor which shall be offset chain sprocket mounted providing at least a 2:1 torque power ratio. Agitator shall be locked in place by 2 – ¼” bolts drilled through agitator shaft between the upper and lower bearing.
Each kettle burner shall be 12 volt, single phase, and 5.8 amps. Diesel fired and provided with valves, regulators, lines and all fittings necessary for operation when supplied from the diesel tanks. The burner assembly shall be mounted on a slide out tray for easy access and maintenance. The kettle shall have a Pyrolite shell combustion chamber. The Pyrolite chamber shall be inserted into a circular stainless steel mount. This chamber shall be 14” diameter X 12” height X ¼” thick. Combustion chamber shell must be replaceable. The combustion chamber must be air tight. The exhaust vents will be the only access to atmosphere. The only air access to the combustion chamber shall be through the burner blower. No fire brick type system is acceptable. A replaceable heat deflector shall be used to protect bottom of kettle.
Kettles shall have both primary and secondary burner/temperature control devices. The primary device shall be an automatic temperature control to maintain heat transfer oil temperature at a pre-set adjustable level in a range up to 550 degrees F. The secondary device is a high temperature limit switch that when activated, this device will stop the 12 volt power to the diesel burner fuel solenoid.
The system shall include a gear-type or pressure comp. hydraulic pump, incorporating a pressure relief valve, hydraulic filter, a bi-directional hydraulic motor geared to rotate in excess of 40 rpm, selector valve, adequate size reservoir with filter screen, shut-off valve, oil temperature and level gauge and all necessary pipes, hoses and fittings to complete the system in accordance with established hydraulic standards. The selector valve shall be positioned in close proximity to the kettle feed door. The valve shall be a four-way control valve to operate a two-way hydraulic circuit from a single hydraulic source. The valve shall allow reversal of the agitator. Controls shall have easy operator accessibility. Each chain drive shall have an adequate removable covering to prevent accidents.
A diesel fueled, air cooled engine of at least 11hp to operate the hydraulic system shall be supplied. The engine shall be equipped with an air cleaner, muffler, adjustable throttle, variable speed governor, alternator and battery charged electric starter.
All exposed metal surfaces shall be primed with a rust and heat preventative and finished in a high heat resistant white paint.
A qualified, factory-authorized service representative shall be available to assure correct use of the unit.
Two copies of an Instruction Manual and parts book for kettles and accessories shall be supplied. The Instruction Manual shall include proper thermoplastic handling procedures.
All equipment catalogued as standard to be furnished and included in purchase price of the unit.
When delivered, the unit shall be completely assembled and ready to operate except for diesel or propane fuel.
All hoses supplied in assembling units described in these specifications shall have temperature and PSI ratings in excess of maximum operating temperatures in pressure fluids and materials being transferred.
The component parts of the unit shall be of proper size and design to safely operate with stresses imposed by maximum capacity operation. Only new models in current production, which are catalogued by the manufacturer, and for which manufacturer’s published literature and printed specification are available, will be considered. Current models may be modified to comply with these specifications.
