Najico’s waterless radiators that support BCPs (business continuity plans)
Emergency power generators supply power in the event of an emergency power outage.
Cooling systems are an integral component of power generators as they cool down diesel engines.
Najico’s cooling systems employ the air-cooling method, which uses no water for cooling. Their cooling ability is retained even in water outages, with no need for water supply like a cooling tower, which is one of their key features.
Consider Najico’s cooling systems if you need to keep your equipment/machinery cool even during emergency situations.
