CM-ATR-X5 Series offers four off-the-shelf cooling options making it one of the most versatile and complete range of military conduction-cooled ATR chassis available anywhere today. Whatever your application, whatever your requirements, you need the highest quality enclosure to protect VMEbus electronic equipment against the most severe conditions, CM Computer has designed it for you.

Our senior engineers have dedicated particular attention to I/O flexibility and easy board integration. No other chassis will offer you a better total solution with such a wide range of practical functionality, innovations, details and options.

Chassis Cooling Techniques

S / SEF / FAC / HES

CM-ATR-45/HES Series CoolingMilitary enclosure heat management is a complex matter and is affected by specific environmental factors and field deployment limitations.

At CM we are convinced that each application requires a different type of chassis, a conclusion that led us to offer twelve CM-ATR-X5 COTS versions allowing our customers to select the optimum enclosure depending on predominant cooling technique, number of slots and internal power dissipation.

Sealed

CM-ATR-25/S - Sealed ATR Chassis

/S

Low cost standard dry-air enclosure with inner fans for internal air re-circulation. Chassis generated heat is dissipated by a combination of cold-plate conduction, radiation and free-air convection through ambient air. This minimum maintenance option is ideal for low wattage applications where ambient air is laden with hostile or harmful contaminants.

Available in size ½ ATR (CM-ATR-25/S), ¾ ATR (CM-ATR-35/S) & 1 ATR (CM-ATR-45/S).

Sealed With Extended Fins

/SEF

CM-ATR-35/SEF - Sealed With Extended Fins ATR ChassisThe ultimate self-dissipation sealed enclosure that also incorporates internal air re-circulation fans. These dry-air chassis are fitted with over-size cooling fins on the top cover, rear panel and side-walls in order to maximise radiation and natural convection. Cold-plate mounting is recommended. These low maintenance sealed chassis are suitable for medium wattage military and aerospace applications.

Available in size ½ ATR (CM-ATR-25/SEF), ¾ ATR (CM-ATR-35/SEF) & 1 ATR (CM-ATR-45/SEF).

Flow-through Air Cooled

/FAC

CM-ATR-45/FAC - Flow-through Air Cooled ATR ChassisNon-sealed chassis in which ambient air is directly forced over the electronic modules using rear mounted exhaust fans. This highly efficient thermal management technique is suitable for full PSU wattage applications.

This type of chassis is a medium cost option that is available in size ½ ATR (CM-ATR-25/FAC), ¾ ATR (CM-ATR-35/FAC) & 1 ATR (CM-ATR-45/FAC).

Heat Exchanger Side Walls

/HES

CM-ATR-45/HES - Heat Exchanger Side Walls ATR ChassisHigh performance dry-air chassis incorporating air re-circulation fans inside. Heat generated with the enclosure is conducted to the hollow sidewalls & rear panel heat exchangers where it is dissipated to the ambient environment by forced air cooling rear fans or by vehicle platform air plenum. A top cover heat exchanger is optional. This chassis version is suitable for sealed applications up to ¾ of total PSU wattage.

This chassis is available in size ½ ATR (CM-ATR-25/HES), ¾ ATR (CM-ATR-35/HES) & 1 ATR (CM-ATR-45/HES).

Setting Chassis Standards


CM-ATR-45 SeriesCM Computer has established a market first by offering the military ATR chassis as a truly organized and universal product range able to meet the complete spectrum of 6U & 3U military applications.

In fact, other manufacturers offer the market only a limited and incomplete set of individual costly enclosures, each designed to solve a single, isolated application.

This new series is more compact, lighter, powerful & flexible than their notable CM-RA-X0 predecessors. Our multiple innovations introduce many unmatched firsts in the industry.

Until now, no other chassis has been able to supply more than 1kW of PSU power on the backplane, integrate four heat exchangers on the chassis structure, improve temperature of the enclosure by up to 15°C, offer unlimited I/O interconnection capability and accept all standard power voltages.

Experience Makes The Difference
