Ellis & Watts has provided high-performance environmental control, specialty trailers, and custom shelters to the meet the demanding climates and applications in the defense industry for over 50 years.

Whether providing shock-resistant, packaged air conditioners for Naval ships, expandable shelters for Air Force fighter pilot training, or equipment coolers for surface-to-air missile radar systems, Ellis & Watts provides custom solutions that deliver critical performance in harsh environments. Our systems are customized to fit your demanding temperature, humidity, pressure, and filtration requirements while operating in extreme ambient temperatures (from -65F to +140F) and harsh environments (such as salty coastal or sandy desert locations). Equipment can be provided with partial or complete redundancy to address downtime concerns. The full range of equipment options is manufactured under a robust quality control system, backed by standards compliance, and proven through post-production factory tests.
