This Johns Manville plant produces asphalt roofing materials. Its Heatec thermal fluid heating system saves the company a lot of money by eliminating the need for a boiler tender.
The plant uses a Heatec 5 million Btu thermal fluid heater to heat a 50,000 gallon asphalt storage tank. The heater is a HCI helical coil heater.
The heater also heats a steam generator, eliminating the need for a fired boiler. Heated thermal fluid from the heater circulates through tubes of the steam generator, heating water surrounding the tubes and converting it into steam.
Asphalt in the storage tank is stored at 300 degrees F. A Heatec booster heater ups the temperature to 450 degrees F as it is pumped into the metering tanks and applied to the roofing material.
