A Little About Us

After decades of industrial manufacturing experience, we took the “expect the unexpected” of unplanned shutdown as our personal challenge. Our predictive, connected devices drastically reduce unexpected downtime and increase production efficiency.
At IoT Diagnostics™, we’re “solving the unexpected” for our customers’ most critical industrial applications. We’re putting plant personnel in control of their daily operations with simple IIoT device integration.
IoT Diagnostics™ is Connecting Prediction to Production.

Stressed Oil Equals Varnish.

Varnish is a generic term for an oil sourced contaminant – a degradation product of the oil.  Over 50 different varnish chemistries have been identified with a wide range of colors, deposits, and effects on machinery.  Causes of varnish include heat, spark, contamination, and overworking of the machine.

Varnish Has Many Culprits, Do You Know What They Are?

What Causes Stress and Varnish?


Thermal breakdown happens at “hot spots” in machinery.  Every 10 degrees celsius increase in temperature can double the speed of some varnish reactions.


In lubricants, charges build wherever shearing forces exist.  Spark temperatures of 1000s of degrees instantly produce many degradation products in the oil.


Both moisture and particulate (particularly metals) can dramatically increase the rate of varnish formation.


Over working the machinery with too high of loads or too fast of run times puts stress on the oil which can increase degradation of oil making varnish easier to form.

Varnish Causes More Problems Than Just Sludge.

What Problems Does Varnish Cause?


Varnished surfaces can see orders of magnitude increases in frictional loads.  Even small increases can affect operation of precision valves like servos.


Sticky varnish deposits capture hard particles flowing by and form a damaging mix.  Metal surfaces and seals wear rapidly.

Power Consumption

Both friction and heat require power to overcome.  One study at a Toyota plant showed a 30% reduction in electrical power consumption when varnish was removed.

Maintenance Issues

Reduced fluid life, increased maintenance and parts replacement, increased downtime, and reduced production are associated with varnish.

Eliminate Varnish With The Estat™

Clean & Protect Components

The Estat super cleans the oil, then begins to absorb and remove built-up varnish inside the system.  Varnish and particles from the fluid and system are retained in the collector.

Extend Oil Life

Because varnish is chemically active, systems maintained with Estat have lower rates of additive depletion and longer oil life.  With better oil health, oil change intervals can be extended.

Monitor Oil Health

The Estat tracks key indicators of oil and system health like water saturation levels, ISO particle counts, oil temperature and other key metrics.

IoT Diagnostics Equipped

Estat is an IoT enabled unit that provides instant oil condition and operation monitoring of your system.  The Estat web app provides 24/7 remote monitoring, alerts, and analytics.

The Power Of Electrostatic Technology

Hard Particles Attraction

Charged particles are attracted by the positive and negative electrodes (electrophoresis), and neutral particles are captured by dielectrical effects within the element (dielectrophoresis).

Oil Works for Itself

Once oil is super cleaned it can then begin to pull varnish from inside pipes and system components.

Just Like New

Not only does the electrostatic technology completely remove varnish from the oil and system components, it also returns the additive level in oil to brand new standards.
