South Africa-based Booyco Engineering has upgraded the heating, ventilation and air conditioning (HVAC) system for a customer’s 8x8 armoured personnel carrier. With almost 40 years of experience in custom designed robust HVAC solutions for the defence sector, the latest prototype is the third iteration of a bespoke unit for this longstanding export customer. According to Grant Miller, Executive Director at Booyco Engineering, the key advances in the latest system have been its integrated electronic control system and the addition of heating functionality.
