DryMax Moisture Reduction Equipment

Dry up hidden causes of downtime

Moisture is the enemy of your transformer. When combined with heat and oxygen, the insulation begins to oxidize which irrevocably damages the entire transformer. Find out how we can help develop a Moisture Reduction Plan utilizing proven DryMax technology. Speak with a specialist.

InsulMax Filtering System

Cleaning up harmful contaminants

Preventative maintenance that includes removing destructive contaminants from your transformers can help diminish the aging process. InsulMax is a substation-grade monitoring and filtering system that removes harmful moisture and trace acids, both of which attack the paper insulation.

SampleSafe Safe Oil Sampling for Cabinet Transformers

Eliminate planned downtime and protect technicians and equipment from arc flashes

Opening the door of a cabinet transformer poses a serious safety hazard. The National Fire Protection Association (NFPA) dictates stringent protocols for working on this type of equipment, including de-energizing the transformer while samples are taken and the use of advanced PPE on cabinet transformers of all sizes. SampleSafe allows technicians to avoid opening the cabinet door altogether, providing a safe and convenient way to obtain oil samples without the need for additional PPE and without shutting down the transformer.
