Transformers are the backbone of any power system: expensive to replace, critical to uptime, and vulnerable to invisible threats like moisture, dissolved gases and oil degradation. HERING’s TIDO® Series is a purpose-built, German-engineered solution that keeps transformers dry, degassed and operational without interrupting service. Whether you’re managing new assets or extending the life of aging units, TIDO® is designed to reduce risk, minimize maintenance headaches and protect capital investment. Below are the top five reasons companies choose HERING TIDO® - each explained in depth so you can evaluate why it should be part of your asset-protection strategy.
1) Continuous Online Drying - Maintain Insulation Health Without Downtime
One of the biggest operational challenges utilities and industrial operators face is drying insulation and removing dissolved moisture from oil while keeping transformers energized. TIDO® performs continuous, on-line drying: it extracts moisture from oil and insulation materials during normal operation rather than forcing you into costly outages for off-line vacuum drying. This capability preserves cellulose insulation, prevents accelerated aging, and stabilizes dielectric strength - all while your system remains live. For grid operators and plants where uptime equals revenue, the ability to treat moisture without interrupting service converts a difficult maintenance activity into a background reliability task.
2) Effective Gas Management - Early Detection and Mitigation of Fault Precursors
Moisture problems are often accompanied by formation of dissolved gases and gas pockets that can signal developing faults. The TIDO® Series continuously degasses oil and reduces dissolved gases, lowering the risk of partial discharge, arcing and catastrophic failure. By keeping gas levels below factory limits, the system reduces the frequency and severity of diagnostic alarms and false positives. In practice, this means fewer emergency interventions and longer intervals between major maintenance actions. For organizations that rely on predictive maintenance programs, TIDO® enhances the accuracy of condition assessments and reduces the likelihood of costly, unplanned replacements.
3) German Engineering and Component Quality - Built for Long-Term Reliability
TIDO® is manufactured to high engineering standards with trusted components that deliver repeatable, long service life. “Made in Germany” in this context means an emphasis on robust mechanical design, precise control systems, and components selected for industrial durability. For asset owners, that translates into lower life-cycle costs: fewer component failures, predictable servicing intervals, and simplified spare-parts management. Investing in a quality system up front reduces the hidden costs of inferior, short-lived equipment - such as repeated repairs, performance variability, and the operational uncertainty that wastes engineering time.
4) Operational Simplicity and Integration - Minimal Disruption, Maximum Control
Modern transformer fleets require systems that integrate cleanly with existing monitoring and control architectures. TIDO® units are engineered for straightforward site installation and intuitive operation, with control panels and sensor interfaces that allow easy reading, remote monitoring and coordination with your asset-management systems. Because the unit works while transformers remain energized, your operations team spends less time coordinating outages or juggling contractors. The result: predictable maintenance work, better use of in-house resources, and simpler regulatory reporting when condition data is required.
5) Measurable Life-Extension and Total Cost of Ownership Benefits
Preventing moisture ingress and removing dissolved gases are not abstract benefits - they directly slow down the chemical and physical degradation that makes transformers fail prematurely. TIDO® reduces the principal drivers of insulation ageing and oil deterioration, which can translate into measurable extension of transformer service life and deferred capital replacement. When you compare the cost of an installed TIDO® unit to the avoided costs of emergency replacements, outage penalties, lost production and accelerated depreciation, the unit is frequently justified as a high-impact investment. In short: an up-front equipment expense becomes a long-term cost-reduction strategy.
