Plastic - Water Tanks, Polyethylene Water Tank and Chemical Storage

HEATING AND INSULATION
HEATING SYSTEMS
• Heating systems for polyethylene tanks are designed for temperature
maintenance only.
• Operate from 120 VAC power source with a low watt/in 2 output to
eliminate any possibility of tank degradation due to excess heat.
• Heater is encapsulated flat foil resistance panels evenly spaced on the
lower portion of the tank. Heating elements are in parallel to provide
maximum reliability.
• Enclosed, weatherproof NEMA 4 thermostat operates up to four panels
in a parallel circuit.
• To adequately design a system we require tank dimensions, anticipated
minimum ambient temperature, wind velocity, and the desired
minimum temperature of the contents.
URETHANE INSULATION WITH UTYLON OVERCOAT
• Spray-on two part polyurethane foam, 2 to 2.5 pounds per cubic foot
density. R value is 7.8 per inch of thickness.
• Overcoat consists of a two-part polyurethane base and a top coat of either Acrylic
(available at additional cost) or Utylon material. Total thickness is 20 mils. Other
coating materials available on a custom basis.
• Standard top coat color is white.
• Materials exhibit excellent weathering characteristics and good corrosion resistance.
• Any damage resulting from handling or shipping should be immediately repaired to
avoid moisture entry.
• Deep insulation gouges may be repaired with aerosol polyurethane foam.
• Overcoat abrasion may be recoated with the Acrylic or Utylon elastomer overcoat.
• If temperature is below 50°F, an industrial grade RTV silicone caulking may be used.
NOTE: Other lower cost options may be available. Please consult with the factory.
