CEDAR LEAF OIL DISTILLATION TANK
Langley August 2003
HOT PIPE COATING ®
The process for distilling the cedar leaf oil involves the application of steam @ 100C - 212F at the bottom of the tank. The " cook " is done when the steam breaks through at the top. Uninsulated this required 5 - 6 hours depending on ambient temperature. The time required was reduced by 2 hours after insulating with the HOT PIPE COATING ® ( HPC ). This new coating is the latest addition to our thermal protection package and is right out of research and development. HOT PIPE COATING ® is designed specifically for straight backside conduction.
The tank was first coated with RUST GRIP ® to permanently stop the corrosion. Surface temperature readings were taken prior to the application of the HOT PIPE COATING ® and registered at a steady state of 100C / 212F. The ambient temperature on 08/28/03 at 12:09PM was 30C / 86F.
A primer coat of HOT PIPE COATING ® was applied using a hopper gun and compressor at a thickness of approximately 50 mils (50/1000"). Initial surface temperature readings showed 70C / 158F. The temperature reduction will increase as the moisture evaporates. The Canadian Roofing Association testing shows that just 1 - 1 1/2% moisture content reduces the effective R value by at least 30%. Water is a conductor not a resistor.
A
build coat was then applied to approximately 100 mils and the surface temperature
dropped to 42°C /104F
A final build coat was applied before the SUPER THERM ® \ ENAMO GRIP ® topcoats with a final thickness of 250 mils ( 250/1000" or 1/4 of an inch ). The final readings showed a surface temperature reduction from 100C / 212F to 24.7C / 76.46F.
The total coating system is comprised
of :
~ RUST
GRIP ® to eliminate any possibility of CUI ( corrosion
under insulation )
~ HOT
PIPE COATING ®
no mold, mildew, fungus or other biohazards growing in the insulation
~
SUPER THERM ®no deterioration by weathering ( exterior application only ) for at least
10 years
~ ENAMO
GRIP ® on the front only to protect
the SUPER THERM ®
where the boiling hot water is poured out.
