<\/a><\/figure>\n\n\n\n<\/a><\/figure>\n<\/figure>\n\n\n\nIn one recent project, these custom engineered solutions are being fitted to specialised hard-skinned radar jamming shelters – manufactured in South Africa by ADG Mobility for export. Built on an ISO-container footprint, these shelters house sensitive electronic systems, radar-interference technology and ballistic protection rated to withstand light arms fire.<\/p>\n\n\n\n
\u201cThis environment creates severe thermal and electromagnetic demands,\u201d he explains. \u201cNot only must the HVAC system maintain stable internal temperatures for both personnel and electronics, but it must do so while complying with rigorous electromagnetic interference (EMI) standards.\u201d<\/p>\n\n\n\n
To meet the demanding electromagnetic compatibility requirements, Booyco Engineering designed the system in accordance with US military standards 461F, which governs electromagnetic interference in military environments. <\/p>\n\n\n\n \u201cWhen you are dealing with radar-related systems even small emissions can compromise performance – so the HVAC unit itself must be part of the protection strategy,\u201d he says. \u201cAcoustic considerations are also important, to ensure a quiet working environment; our system therefore operates at around 50 dB, significantly quieter than a typical office unit.\u201d<\/p>\n\n\n\n To meet the extreme thermal specifications imposed by the shelters, the HVAC system is engineered for operating temperatures from minus 40\u00b0C to plus 55\u00b0C, with a maximum cooling output of 9 kW and heating of around 6,5 kW. The HVAC design must also accommodate the challenging shock and vibration demands of mobile military platforms, aligning with both MIL-STD-810G and the AECTP-400 requirements for mechanical stresses.<\/p>\n\n\n\n \u201cThese shelters are mounted on military trucks that move over rough terrain, so the system must endure the same treatment,\u201d Miller says. \u201cIt is not a plant room system; it has to survive real military deployment.\u201d <\/p>\n\n\n\n Other features of the system include chemical, biological, radiological and nuclear (CBRN) filtration as well as cyclonic dust filtration for high particulate environments. There are also built-in test functions and sensors such as onboard carbon dioxide monitoring and advanced digital scroll compressors that ensure tight thermal stability for sensitive equipment. Despite the system\u2019s complexity, Booyco Engineering designed and developed the shelter HVAC in an accelerated timeframe, he notes.<\/p>\n\n\n\n \u201cIt has been a rapid development programme, made possible by the foundation of knowledge and experience Booyco Engineering has built up from previous systems engineering,\u201d he says. <\/p>\n\n\n\n In a separate contract with a southeast Asian government, Booyco Engineering is supplying a dedicated HVAC solution for a latest generation 8×8 amphibious infantry fighting vehicle. Rated for operation up to 49\u00b0C and down to minus 10\u00b0C, the Booyco HVAC unit integrates CBRN filtration and advanced environmental protection. <\/p>\n\n\n\n \u201cThe CBRN system protects occupants of the vehicle from harmful gases or chemical agents,\u201d Miller explains. \u201cThe filtration activates and removes harmful particulates and gases through high efficiency particulate air (HEPA) and carbon filters to protect both the crew and the vehicle\u2019s electronics.\u201d <\/p>\n\n\n\n Having built a strong relationship with this customer over almost 15 years, Booyco Engineering has successfully developed systems that withstand exceptionally harsh climatic and operational conditions. In amphibious applications, for instance, humidity and salinity – as well as rapid thermal shifts and continuous vibration – create a uniquely demanding environment for climate-control systems, he says. The project includes a full prototype as well as several pre-production units to undergo qualification testing. <\/p>\n","protected":false},"excerpt":{"rendered":" As geopolitical uncertainty drives renewed defence investment in many regions, South Africa-based Booyco Engineering is providing specialised industrial HVAC solutions to a global customer base.
