NDM is one of the world''s largest volume manufacturers of FAA approved
oil coolers. An approved supplier to both Lycoming and Continental, as
well as many airframe manufacturers, NDM holds FAA/PMA''s for most of
these oil coolers. NDM oil coolers are manufactured utilizing the vacuum
oven brazing process rather than the less costly CAB (controlled
atmosphere brazing) method used by others to save costs.
Utilizing the vacuum oven process guarantees a high-quality product and lower warranty returns.
