The job involved designing and commissioning a -25°C freezer room and a 4°C cold room to store ice core samples obtained from recent Antarctic surveys. The freezer room was equipped with a run and standby system, while the cold room had two running units and one standby unit. Additionally, external beacons and sounders were installed to activate a person trapped alarm and a high-temperature alarm in case of emergencies. This ensured the safe storage of the ice core samples, which are vital for studying climate change and polar ice sheet dynamics. Correct installation and operation of the freezer and cold rooms, along with the alarm systems, were critical to the success of this project.
