Klinge Corporation, the specialist manufacturer of transport refrigeration equipment, has completed acceptance testing of their military refrigerated A-frame container systems at a state-of-the-art test facility in the US. Their military container systems passed a multitude of MIL-STD tests, which are US military standards that emphasise tailoring equipment’s design and test limits to the conditions that it will experience throughout its service life.
The testing regime 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 5mph to 35mph simulating intermediate and severe off-road and cross-country conditions.
As part of the electromagnetic interference testing, the Klinge military refrigerated container met CE 102 requirements — power leads (10kHz to 10MHz). Conducted emissions (CE) are the radio frequency noise present in the physical wiring an electrical system. The system also withstood subtest CS114 testing – bulk cable injection (10kHz to 200MHz) 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 the low-temperature operation testing, the military refrigerated container was functional and maintained an internal temperature of 55° throughout the 24-hr cold cycle (ambient temperatures ranging from -6°F to -21°F). For the high-temperature operation testing, the military refrigerated container was functional and maintained an internal temperature of -4°F throughout the 24-hr hot-dry cycle (ambient temperatures ranging from 90°F to 122°F).
The Klinge military refrigerated container, consisting of a refrigeration unit, generator set, and an international organisation for standardisation (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 optimal reliability and multiple-temperature functionality.
"Successful completion of these military tests showcases our equipment’s ruggedness, durability and reliability, which is of vital importance in tactical environments. Klinge Corporation continues its tradition of providing quality military refrigerated containers to armed forces and government bodies the world over," said Klinge Corp sales manager, Jason Flynn.
As part of a multi-year contract worth more than $5 million, Klinge Corporation will produce 60 refrigerated containers based on a standard 20′ ISO-container with a hook frame for HEMTT or PLS lift trucks.
