DryMax® Moisture Reduction Equipment


Reliability isn’t a game, and putting your entire production system at risk is no joke. That’s why SDMyers takes your transformer’s moisture content seriously. Utilizing proven DryMax® technology, we can help develop a DryMax Moisture Reduction Plan (DMRP) that proactively protects your critical electrical assets from irrevocable water damage.


How Does DryMax® Work?

DryMax is an energized online dryer solution that connects directly to your live transformer for as long as it takes to completely remove moisture – while your transformer stays put and in service. Upon installation, it immediately starts preventing further degradation of your paper insulation to improve your reliability. Along with a trusted service agreement, the DryMax solution offers:

  • Effective moisture removal for both oil and paper
  • Remote monitoring and control
  • Flexible solution packages
  • 50+ Years of SDMyers transformer expertise

Can I Use Another Method?

There are four primary methods of transformer moisture removal, but their effectiveness varies considerably. DryMax is the only solution that dries out the paper without taking your transformer out of service.


The longer you wait, the more you risk.

Moisture is more than a threat – it’s the enemy, and one that is actively attacking your transformer. If left alone, or treated improperly, a wet transformer faces a significant risk of failure. Check it out:


How Do You Get Started?

Excessive moisture contributes to component degradation that can suddenly and permanently end the life of your transformer. A DryMax® Moisture Reduction plan tackles moisture holistically and aggressively, protecting your entire fleet for its entire lifespan without a single day of downtime.

Such a comprehensive approach involves monitoring and removing the moisture from your transformer until the PPM reaches and acceptable and stable level. 

A fleet-wide plan can include both service-only dryouts and DryMax ownership to meet the needs of your equipment, typically involving a combination of the following programs:

Service-Only Program

  • Recommended if you have multiple transformers with immediate needs
  • All the benefits of remedial moisture reduction without the long-term commitment of multiple unit purchases
  • The same dedicated service from SDMyers as ownership programs

Permanent Installation Program

  • Recommended for critical transformers and equipment under extremely demanding loads
  • One transformer, one DryMax
  • Dedicated DryMax unit and service package
  • Installed for the lifetime of the transformer

Mobile Installation Program

  • Addresses needs of the entire fleet
  • Removes and refits your DryMax units to multiple transformers as needed

Equipment Redeployment Program
