Heavy Duty Poly Storage Tanks - Bailiff Enterprises
Insulated Double Wall Poly Tanks
Our insulated poly tanks are
standard tanks with a 2" thick layer of Polyurethane closed
cell foam insulation applied to all outer surfaces except
for the bottom of the tank. Closed cell foam, as
opposed to Open cell foam, is comprised of sealed foam
bubbles that do a better job of insulating and do not soak
up moisture like a sponge. The layer of insulation on
our tanks is sealed with a White mastic coating.
The polyurethane closed cell insulation on our tanks has an
R-value between 6.0 and 6.5 per inch of thickness.
With a 2" layer, the R-value is between 12.0 and 13.0.
Since this is a sprayed foam product, the properties can
vary slightly from one tank to the next.
The polyethylene vertical and open top tanks meet
standards set by ASTM D 1998. There are no ASTM
standards written for other tank shapes or resins.
These insulated tanks do not include Heat Tracing.
Heat Tracing is the use of specially designed Heat Pads and
a digital control box to keep liquids from going below a
pre-set temperature. For water storage, this would be
to keep the water from freezing. For Sodium Hydroxide
or Caustic Soda storage, the maintenance temperature would
be at least 65 degrees and possibly as high as 85 degrees.
We can easily add Heat Tracing to any of these tanks.
We need a bit more information to properly calculate the
right heat pads. Click here to give us the Zip Code
