30 Men Central Control Room (CCR) / H2S Protection Shelter


The Uniteam 30 Men Central Control Room is a complete package of H2S Shelter in Place (SIP) and HVAC equipment, designed to be delivered and installed in a modular building at Gas Plants. The building serves as a CCR during normal operations and as a safe place for plant personnel during emergencies, where it can accommodate up to 30 people for 2 hours.

The SIP consists of 181*0.05m3 high-pressure cylinders, and the system pressure is 30Mpa. A system compressor fills the high-pressure cylinders with fresh air when the quality of the external air is normal. In the event of a gas release or emergency, the gas protection function enables. The high-pressure air is then depressed by the depressurizing system, and fresh air is supplied to the main room. The SIP maintains a micro-positive pressure of 50pa in the main room and 25pa in the air-lock area, effectively blocking hazardous gas from entering. Also, due to the internal pressure in the SIP being slightly higher than the atmospheric pressure, the internal air will vent through the check valve, while the hazardous gas is blocked outside.

Moreover, the SIP is equipped with a 250KW cooling and ventilation system, ensuring comfortable working conditions for personnel. The system is designed to maintain an operational temperature range of +45 °C to -20 °C, providing a comfortable working environment even in extreme weather conditions.
