Rackmount Cases for Mil-Aero / Gov

Protection features

• Against mechanical loads such as shock, impact and vibrations.
• Protection against electromagnetic interference such as radio waves, lightning and general environmental influences such as heat, moisture and dust.
• The electronic equipment requiring protection is placed and fastened in place inside elastically suspended anti-vibration frames for optimal protection.

primarily for use in

• Military applications, telecommunications and the electronics industry
• Transport infrastructure such as rail security and traffic management systems
• Anywhere where sensitive electronic equipment requires mobile use or outdoor installation

Unwanted mechanical vibrations often occur during transport and other situations. These may have a negative effect on the functioning of electronic components and thus represent an increased safety risk.

Mitraset rackmount cases offer a solution to vibration problems in military, aerospace as well as in industry applications. They are tested to MIL-STD-810.

For special requirements, a modified Mitraset rackmount case has been developed and undergone successful testing in accordance with the strict MIL-STD-810 F specifications.

ZARGES also develops customized solutions according to your specifications.

The diagram shows the test specifications according to FIGURE 514.5C-3.: Composite wheeled vehicle vibration exposure.

RF screening

Mitraset 19″ rackmount cases made of aluminum have significantly improved RF screening properties compared with plastic cases. When required, these properties can be further improved through special measures.

On cases with closed lids:

• • • By using a special lid seal.
    • Opening through RF honeycomb filter, IP 54 shielding. Installed primarily in the lid.

On cases with open lids:

• • • By fitting aluminum infill panels on 4 sides of the standard inner frame. Optionally perforated for better air circulation. In addition, the front and back of the frames are fitted with an RFI gasket.
    • By fitting a flexible skirt seal made from conductive material between the outer case and the anti-vibration frame.

Wire rope shock absorbers

For particularly high loads or to absorb vibration, the 19″ frame featured on this variant is suspended on wire rope shock absorbers at an angle of 45°. The external dimensions have been increased correspondingly due to the increased size of the frame. This special version is available only for Mitraset Classic.

Special Applications / Custom Solutions

ZARGES provides you with the rackmount cases and solutions for a range of uses, e.g. in planes, in vehicles or for special deployments. These range from transport systems and rackmount cases with dampers through to dust and water protected as well as reinforced products for extreme conditions

The Mitraset 19″ rackmount cases offer a multitude of customized special solutions in addition to a large range of standard accessories.

Mitraset 19″ rackmount cases offer the appropriate solution according to the application, the type of electronic equipment operated, ambient temperatures and the resulting air-conditioning requirements.

Details

The guide figures calculated in the table may be influenced by various factors, e. g.:

• • • Paint type and color
    • Internal air circulation
    • Location and position of the rackmount case
    • Influence due to adjacent rackmount cases
    • Weather and climatic conditions
    • Mitraset 19″ rackmount cases – customized solutions with air-conditioning

19″ rackmount case applications increasingly require air-conditioning. ZARGES is therefore able to provide adaptable special rackmount cases for air-conditioning. Cutouts for plugs, ventilation plates and the ZARGES heat exchanger lid complete the offer.

Heat exchanger lid

The ZARGES heat exchanger lid ensures protection class IP 65 by means of 2 separate air circuits. Robust fans ensure that air is constantly circulated. Heat transfer between the two circuits takes place in a specially designed heat exchanger in the interior of the lid.

Heat dissipation depends on temperature conditions and on the location and position of the rackmount case. These solutions can be built by ZARGES according to customer specifications.

Customer Examples of Cooling Systems

Air-conditioning units are combined with Mitraset only according to requirements. Transport takes place in in-house vibration-tested transport containers with customized foam inserts.
