Klinge Corporation has completed acceptance testing of its Military Refrigerated A-Frame Container systems for the Swedish Armed Forces at a state-of-the-art test facility in the United States.

Klinge Corporation, the specialist manufacturer of transport refrigeration equipment, has completed acceptance testing of its Military Refrigerated A-Frame Container systems for the Swedish Armed Forces at a state-of-the-art test facility in the United States.

These military container systems passed a multitude of MIL-STD tests, which are US military standards that emphasize tailoring an equipment’s design and test limits to conditions it will experience throughout its service life.

Testing included vibration, electromagnetic interference, low-temperature operation, and high-temperature operation.

For vibration testing, the Military Refrigerated Container was secured to the HEMTT and was payloaded during transport. The Military Refrigerated Container was then transported over a variety of surfaces at speeds varying from 5 to 35 mph, simulating intermediate and severe off-road and cross-country conditions.

As part of the electromagnetic interference testing, the Miltary Refrigerated Container met CE 102 requirements—power leads (10 kHz to 10 MHz). Conducted Emissions (CE) are the radio frequency noise present in the physical wiring of an electrical system. The system also withstood subtest CS114 testing— Bulk Cable Injection (10 kHz to 200 MHz) without sustaining damage or degradation in performance. Conducted Susceptibility (CS) 114 addresses interconnecting cables/signal lines. The container was also tested to MIL-STD Radiated Emissions and Susceptibility tests.

For low-temperature operation testing, the Military Refrigerated Container was functional and maintained an internal temperature of 55º throughout the 24-hour cold cycle (ambient temperatures ranging from –6º to –21º F). For high-temperature operation testing, the container was functional and maintained an internal temperature of –4º throughout the 24-hr hot-dry cycle (ambient temperatures ranging from 90º to 122º F).

The Klinge Military Refrigerated Container, consisting of a refrigeration unit, generator set, and an International Organization for Standardization (ISO) A-Frame container, offers multi-temperature refrigeration. The system features integrated hydraulic rollers allowing for easy loading/unloading and a manually operated hydraulic pump.

The primary function of the Military Refrigerated A-Frame Container is to cool and preserve food (perishable and dry goods) for maximum longevity, minimizing food loss while offering reliability and multiple-temperature functionality.

As part of a multi-year contract worth more than $5 million, Klinge will produce 60 refrigerated containers based on a standard 20-foot ISO-container with a hook frame for HEMTT or PLS lift trucks.
