Transformer oil coolers
Enerfin’s transformer oil coolers are custom designed for each application, in keeping with your needs. We have four types of coolers to suit most applications.
The OFAF (Oil Forced Air Forced) model is designed and manufactured with our extruded aluminum fin tubes. The coolers are delivered with motors and fans assembled and connected.
The OFWF (Oil Forced Water Forced) model is of the shell and tube type. This model can be manufactured using two concentric tubes with a double tube plate, equipped with a leak detector (optional).
The FURNACE Cooler (OFWF) is also of the shell and tube type. In this case the oil is circulated in the shell side. The water side of the tube can be divided in single or multple paths.
The ONWF (Oil Natural Water Forced) model has a natural convection design. This model is manufactured using our extruded aluminum fin tubes inside a rectangular shell to optimize thermal performance. This model can also be manufactured using two tubes with a double tube plate, equipped with a leak detector (optional).
