Qualitrol Company LLC products

Side mounted bi-metal thermometers with temperature indication and reset-able maximum temperature pointer. Features up to 3 control and/or alarm switches (contacts). Models can be combined with a well (pocket) to allow for replacement without draining or compromising the tank.

Capillary based, remote indicating, mechanical thermometer. Features a compact design for space restricted applications and bourdon tube measurement with resettable maximum pointer. Available with up to 3 switches for temperature related alarms and control signals.

Designed to provide operating control, limit or alarm functions for transformers and load tap changers. Contacts can be factory set or adjusted as needed. The snap-action switch automatically resets when pressure returns to pre-set conditions. Pressure and/or vacuum switches can be combined on a common manifold and protected by optional enclosure. Optional pressure indicators (dial gauges) are available on select models.

Mechanical over pressure protection device with integrated directional discharge outlet. Provides pressure relief and insulating fluid containment (requires optional piping) on transformers and load tap changers during over pressure conditions. Automatically reseals once pressure has fallen.

Supplementary plastic box to store your T1 fiber optic temperature probe.

Excess moisture from the atmosphere may degrade a transformer bladder, oil and insulation system over time. This degradation causes unnecessary aging to the asset, reducing the overall life and performance. This can lead to additional maintenance or even premature and unexpected asset failure in the future. A dehydrating breather can extend the life of your asset.

Harsh polar climates require transformer accessories designed and engineered to handle these extreme cold environments. Qualitrols line of Polar Xtreme® instruments tackle these temperature extremes to ensure performance even on the coldest days of the year (down to -60 ËšC).
