VARIOS Automated Dryout Curves

Automated Thermal Dryout Curves

Constructing a thermal dryout curve is a painstaking process with the potential for human error. Time and effort go into acquiring and setting up the right components, plus you spend hours mixing samples, taking measurements, and fitting the data into a curve. What if you could have something more accurate, more reliable-and more automated? You can. Introducing VARIOS.


Get more done by getting automated. Remove the tedium and the
human error out of thermal dryout curves with VARIOS. It
automatically generates complete, high-resolution dry down curves
with less effort and less cost, so you can focus on what you love.

Engineered for accuracy

VARIOS was specifically designed to create thousands of thermal dryout
curves for the 400 mile Suedlink underground cable installation in
Germany. So it's engineered to be accurate, affordable, and low
maintenance. It combines legendary TEMPOS and HYPROP technology to
measure thermal conductivity as a function of soil water content. And
it's easy. Just insert the needle into a saturated soil sample, and put
it on the balance. VARIOS automatically makes hundreds of precision
thermal conductivity measurements while the water evaporates from the
sample. The mean water content is calculated based on a continuous
recording of the sample weight change. Powerful software does all the
calculations, visualization, and fitting automatically, reducing the
possibility of error.

Reliable and compliant all-in-one solution

The IEEE 442-2017 and ASTM D5334 compliant VARIOS uses the transient
line heat source method. That means it's a reliable measurement with
short heating phases and low heating power. This reduces water movement
due to heating and convection and reduces the measurement time. It
automatically corrects for temperature drift, and heating power and time
can be optimized for specific materials or properties. Plus, every
dryout curve has hundreds of data points, so you get the detailed
information you need to make the right decisions. And VARIOS is an
all-in-one solution. It comes with everything you need to make complete
thermal dryout curves including cables, installation tool, and software.
There's nothing else like it on the market.
