Photos show the a few examples of insulated tanks.
Our insulated tanks are covered with a 2" thick layer of sprayed-on, closed cell polyurethane foam insuation. The insulation is covered with a white mastic sealant that protects the insulation from UV rays. These tanks can be ordered with heat tracing (heat pads) that are attached before the insulation is applied. The heat tracing comes with digital controls.
We offer most of our tanks in insulated versions. We have several shapes including vertical, cone bottom, and
horizontal. Some of our insulated tanks are
available in more than one type of plastic.
Polyethylene is the most widely used plastic resin for
making storage tanks due to its relatively low price and
good chemical compatibility. The polyethylene used is
HDPE. HDPE (High Density Polyethylene) is sometimes
conveniently but incorrectly referred to as HDLPE.
Specific Gravity Ratings:
Many of our insulated tanks are available in more than one
specific gravity rating. We have some tanks that are
rated for "Water Only", while others are rated at 1.5
specific gravity, 1.9 specific gravity or even 2.2 specific
The Vertical Polyethylene tanks meet the wall thickness
standards set by ASTM D 1998. The ASTM standards were
not written to apply to other shapes of tanks.
If you are selecting an insulated
tank for chemical storage be sure to click on "Storage
Applications" on the menu. You can select the chemical
you are storing and find out the chemical compatibility with
each kind of plastic and the materials of construction of
