Trojan Dry Out System (TDOS Series)

Designed for long term, unattended operation on energised transformers, the TDOS uses large capacity adsorbent filters to remove moisture in the oil and cellulose insulation to very low levels. Typically used as a portable piece of equipment on a stand or trailer, the TDOS can be used on a number of transformers annually.

Using a patented process, the water removal filters are automatically redried at regular intervals, ensuring maximum water removal efficiency & low ongoing cost of operation (i.e.: extremely low consumables requirements). The filters are typically changed every 18-24 months.

The TDOS has three optional treatment cycles: Analysis, Degassing (Low Vacuum & High Vacuum models available) & water removal, providing the owner with significant processing capabilities in the one system. The TDOS is the most versatile online dry out system available in the world.

The TDOS is simple to use, has numerous interlocked safety features, and includes remote monitoring & communications as standard.
