The MILEX case is a water and dust proofed, shock and vibration absorbing aluminum transit case for 19 inch electronics. MILEX transit cases are NATO approved and designed to meet the rigid requirements of U.S. MIL specifications and other MIL standards worldwide.

OVERVIEW

MILEX aluminum transit cases are engineered to meet the stringent requirements of MIL-STD-810G and other relevant military standards. They are meticulously designed and manufactured to provide the specific environmental protection needed for the equipment being transported. This design ensures maximum protection while incorporating other essential and desirable features, making MILEX cases highly reliable for demanding military and industrial applications.

ACCESSORIES

MILEX aluminum transit cases offer a comprehensive range of accessories, including cooling systems, racks, drawers, and slides, making them the most versatile line available for the secure packaging of mobile electronics. These cases are custom-made to meet the exact specifications of the customer. DESAPRO’s expertise in design and custom manufacturing ensures the right quality for your application, delivered precisely when needed for optimal performance.

DIMENSIONS

MILEX cases are tailored to the specific dimensions of the equipment they protect. Thanks to the strategic positioning of DESAPRO shock mounts, the space between the inner chassis and outer shell is minimized while maintaining equal or superior shock and vibration properties. This design ensures MILEX cases are as compact as possible without compromising protective characteristics, offering efficiency and maximum protection in a streamlined package.

Protection against Environmental Stress:

Undesirable influences from various sources which occur during transport, storage, or operations can have a damaging effect on sensitive goods and therefore present a considerable risk. These risks are mitigated by using DESAPRO cases. DESAPRO cases protect against many environment stress’s:

Protection against climatic stress such as:

  • Extreme temperatures in tropical or arctic regions
  • Temperature shock in airborne situations
  • High humidity in tropical regions
  • Aggressive atmospheric conditions such as salt fog at sea
  • Sand and wind in deserts or industrial settings
  • Water damage by rain or transport by sea
  • Sun radiation (UV rays)
  • Rain, snow, hail

Protection against electrical stress by direct or random high frequency interference:

  • Jamming transition
  • Switching operations

Protection against internally product stress:

  • Dissipated heat
  • High voltage components
  • Radio frequency radiation

Protection against foreign objects:

Main components of the
DESAPRO MILEX aluminum transit case

The MILEX Aluminum Transit Cases consist essentially of three main parts:

Desapro Aluminum MILEX
Housing
Isolators
Chassis
Gasket
Cover

Self-supporting housing

A  welded and rigid construction forms a self-supporting shell that is both light and rugged. The entire aluminum construction is shock proof and resistant to extreme temperature change, conductive and fully recyclable. Stacking feet on the bottom and indentations on the top of the housing provide stable stacking of the cases. The standard equipped cases include a pressure equalization valve. Case connections and securing the cases to any bolting pattern are available for specific applications.

Shock mounted chassis

The core of the case is a shock mounted chassis. Depending on the model and size, equipment can be fitted either from the front or the rear of the case. In order to keep the weight down and allow for optimal ventilation, the chassis are designed with large holes. The chassis is connected to the housing shell by an electrical ground strap.

Cover

All MILEX cases are protected against outside influences through a bolted cover with gasket. Easily operated closures are recessed in the housing cover and ensure a solid seal. The cover space can be used for I/O panel, windows, cable pouches, ventilation louvres etc.

Types

There are four types of MILEX 19 inch rack mount Transit cases

SHOCK MOUNTED

The MILEX 19’’ Transit Cases are intended for use in extreme conditions. The electronics are attached to a shock mounted chassis, not directly to the shell. A minimum of 8 shock and vibration absorbers serve to deflect any mechanical stress on the housing. After attachment of the chassis, the case is securely sealed with a cover to protect the contents against dust, sand and water.

HARD MOUNTED

The MILEX Hard Mounted Transit Case is a standard 19-inch case without a shock-mounted chassis, designed for applications where vibration protection is not essential. It retains all other protective features and maintains the same outer dimensions as the shock-mounted version, ensuring your equipment remains secure even in stable environments.

WIRE ROPE

The MILEX Wire Rope Transit Case is a 19-inch case featuring a chassis mounted on stainless steel spiral wire rope shock absorbers. These absorbers are specifically designed to protect sensitive electronics from vibration and severe shocks. The wire rope system provides the necessary deflection not offered by standard shock absorbers, ensuring superior protection. This design is particularly effective in demanding environments such as ships, submarines, helicopters, and other aircraft where shock protection is critical. MILEX ensures reliable security for mission-critical equipment in the harshest conditions.

SPECIAL

MILEXPRO is the newest generation of robust transit cases for the transport of sensitive electronics, IT, and measuring systems. It combines the high value by shortening the integration time of your hardware and easy access during transport and/or in operations. The closing system is unique and supported by a revolving frame system, which is guided in the X- & Y- axis thus centralizing the cover automatically. The long lasting original features of the MILEX are kept in place enabling the stacking compatibility is possible with other MILEX cases.

The main advantages of the MILEXPRO are:

Long lasting shelf life

The lifetime of the integrated product is increased due to improved and innovative mechanical features of the MILEXPRO supported by the centuries of Know How and experience in the manufacturing of aluminum cases for transport of sensitive goods under most extreme environmental conditions.

Optimal protection and flexibility

In operation the user is equipped with maximal protection through a fundamentally improved case construction which protects even better against shock and vibration. The individual choice of shock mounts offers a universal usage of the MILEXPRO. The shock mounts can be changed easily on the fly if necessary later in operations if a different payload is mounted in the case due to the profile enforced shock mount carrier plates. Through the separated sealing and HF-shielding system there is always an environmental protection and the HF-shielding can optionally be added later on if needed.

Cost savings

The enormous reduction in integration time and thus cost savings is unique due to the entire removal of the internal chassis. The possibility to warehouse cases and chassis separately also reduces the amount of storage space and, as a plus, helps prevent scratching of the case in the integration phase. Due to the free access of the chassis an optimal cable management is secured. Time saving through clean and efficient integration management is possible.
