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.
