Coast Guard vessels and Navy vessels for countries around the world have relied on full Delta "T" Systems' engine room ventilation packages to keep them running strong for extended periods of time. A testament to the value of an engineered ventilation system from Delta "T" Systems can be found in a study that the U.S. Coast Guard performed on the 87' Coastal Patrol Boat fleet:

Studies done by the U.S. Coast Guard have determined that Delta "T" Systems' complete ventilation systems can save $5 million in terms of fuel and engine overhaul expenses over the life cycle of each vessel in the 87CPB fleet. Each craft is expected to operate for 25 to 30 years.
