Insul-Dryer Transformer Dehydration System

Our state-of-the-art online transformer dehydration system — Insul-Dryer — offers effective protection against wet insulation. The dry-out equipment has portable oil dehydration units, is easy to install, and helps in preventing costly downtime.

Transformer Oil Reclamation Plants

Self contained and fully independent, our oil reclamation plants have column media installed permanently for 2-3 years. Not only is the oil reclamation and media reactivation fully automatic, but also the media is totally free from oil contaminants after use.

Transformer Oil Dehydration Plants

Our dehydration plants are extremely effective in removing water, dirt, and gasses from the transformer oil.

Mobile Cartridge Filters

Our mobile cartridge filters are extremely versatile, removing particulate matter to 0.5 microns. The mobile filters provide carbon filtration for LTCs and OCBs and are easy to handle.

Cold Trap

The Cold Trap (Cryogenic Vacuum Pump) measures the amount of moisture being removed, which allows accurate tracking and verification of completion of the dry-out process.

Cool-A-Tran

As power needs continue to increase and loads approach full-load capacity on your transformer, additional cooling is an option to extend the life of your transformer. Cool-A-Tran is an auxiliary, stand-alone transformer cooling unit. It consists of an air-cooled heat exchanger, oil circulation pump, flow switch, flow gauge, and control box. It effectively reduces the operating temperature of the transformer by dissipating heat from the transformer oil.
