  • Cold Aisle Cabinet System Principles

    Cold Aisle Cabinet System Principles

    Cold aisle containment systems use doors at aisle ends, ceiling panels or lids above racks, and structural frames to create enclosed zones where cold supply air flows directly to IT equipment intakes. Without containment, cold supply and hot exhaust air mix throughout the data. Beyond implementing basic measures such as sealing moisture out of the data center and improving air flow, aisle containment to prevent the mixing of hot and cold air stands out as a method that can dramatically reduce energy costs, minimize hot spots and improve the carbon footprint of data. Hot aisle and cold aisle containment are foundational concepts in data center design. When implemented correctly, they improve efficiency, reduce energy consumption, extend equipment life, and enhance overall reliability. Cross-Guard, as a manufacturer and installer of both aisle containment solutions, has over a decade of experience working alongsid tors, beyond the veneer of efficiency figures. We also share the findings of a live data centre study of cold aisle.

  • New Zealand Cold Passage Armor

    New Zealand Cold Passage Armor

    New Zealand Multi-Terrain Pattern (also known by the acronym NZMTP) is the standard camouflage pattern of the New Zealand Defence Force (NZDF). It replaced the multi-terrain camouflage uniform (MCU) and older New Zealand disruptive pattern material (NZDPM) variants beginning in 2020. The pattern is derived from the British Multi-Terrain Pattern (MTP), itself based on Crye Preci. HistoryPrior to NZMTP, the NZDF issued the MCU (Multi Terrain Camouflage Uniform), introduced in the 2010s. While MCU was designed to be versatile, reasons for the change included feedback from operational deployment. NZMTP is visually similar to the British MTP and the original Multicam pattern. It uses a multi-environment color palette of greens, browns, and tans that blend effectively in woodland, desert, and transitional terrains. Minor varia.
