Rack mounted load banks are designed for a standard 19-inch server rack, widely deployed in data centers and laboratories. Available in air-cooled load banks and liquid-cooled load banks, the air-cooled model covers a power range from 1kW to 20kW, while the liquid-cooled type supports 1kW to 40kW. These units accurately simulate real heat load and operating characteristics of data center servers. They conduct compliance and durability tests for HVAC systems, hot aisle solutions, power distribution facilities, and water circulation systems. Critical for data center commissioning, routine maintenance, and performance verification, they ensure stable operation and energy efficiency of overall data center infrastructure.
