Product Summary

As a transformer operates, oil expansion and contraction causes a transformer to breathe. Humidity from the atmosphere may degrade a transformer bladder, oil and insulation system over time. This degradation causes unnecessary aging to the asset, reducing the overall life and performance. This can lead to additional maintenance or even premature and unexpected asset failure in the future.

The Qualitrol STB series smart transformer breather removes moisture from air entering oil-filled transformers or LTC conservators. The breather is automated to regenerate the silica gel desiccant at a user selectable time interval - Parts Per Million (PPM) or Relative Humidity (RH) threshold - avoiding unnecessary trips to site to refresh the desiccant. The silica gel may be regenerated without replacement due to internal heaters inside the unit that drives out moisture on a transformer exhale cycle.

Universal Model

Available in either 1kg or 2kg designs, the STB000 monitors the breathing pattern of the tank and switches between main tank and LTC operation automatically. Multiple mounting options are available for fitting to a new or retrofit installation. Internal cabling allows for easier installation and eliminates unintentional damage to cabling in the field. Desiccant regeneration is configurable by the end user based on % Relative Humidity (RH), Parts Per Million (PPM) or time frequency (days).

Asset Health Insights

More often than not, a transformer failure is an economic disaster. Most of the time, the economic impact comes from the wait time for a replacement. By not actively monitoring your transformer you could lose revenue, experience catastrophic failures, and have major safety and environmental impacts. The STB000 enables trending and remote monitoring for a better insight into the health of your asset.

What else does the STB000 offer?

  • First universal, maintenance free breather for both LTC and Main Tank applications
  • Recommended for use on medium/large transformers
  • For peace of mind, each breather comes with a five year warranty as standard
  • Available in either 1kg or 2kg designs (STB breathers are sized based on the quantity of oil housed within the system)
  • Single side mounted indication LED indicates quick and easy breather status including power/normal operation, regeneration mode, and error codes

Special Applications

Harsh marine and polar climates require transformer accessories designed and engineered to handle these extreme environments. Qualitrols line of Offshore Xtreme™ and Polar Xtreme™ smart transformer breathers tackle these saline and temperature extremes to ensure performance even in the harshest of conditions.

The Qualitrol Offshore Xtreme™ Smart Transformer Breather removes moisture from air entering oil-filled transformers or LTC conservators. The PE breathers regenerate and operate in the same manner as the standard line of breather offered by Qualitrol, but offer additional protection in a saline environment. Offshore Xtreme™ breathers are engineered with advanced material sets to withstand the additional environment constraints, including stainless steel, reinforced fiberglass and glass components.

The Qualitrol Polar Xtreme™ Smart Transformer Breather removes moisture from air entering oil-filled transformer or LTC conservators. The PE breathers regenerate and operate in the same manner as the standard line of breathers offered by Qualitrol, but offer additional protection for the polar climate. Polar Xtreme™ breathers are engineered to house additional heaters to prevent condensate water from freezing at the outlet of the breather. The addition of these heaters ensures proper drainage after the silica gel has been regenerated in extremely cold temperatures.

Using knowledge gained with our first generation product and gathering customer feedback, we have developed the first universal maintenance free smart breather. It is an exciting innovation for the industry.
