Extend the Life of Your Transformer

Traditional cooling based on temperature alone results in an "Overshoot" of the winding temperature set point. This results in unecessary heating and accelerated loss of life for your insulation. With traditional cooling, it happens every time your winding hot-spot temperature reaches a set point.

pre-cooling

APT's unique Load Pickup Cooling technology uses load current to determine when to start pre-cooling your transformer! Therefore, you avoid unecessary temperature "overshoot" and save transformer life.

Applications for Load Pickup Cooling

Load Pickup Cooling can be used on virtually every transformer. However, our patented pre-cooling technology is ideally suited for:

Windfarms
Industrial Loads
Transformers with wide load fluxuations

Rated Load Current (each winding)
Load Pickup Set Points (pickup and dropout)
- Up to 2 Set Point Levels per winding!
Load Pickup Timers
- To ride through faults and switching events
