SL20 Server Rack Heater:
Precision Heat Generation for Server Racks

Load Banks Direct, LLC is a leading manufacturer of high-capacity Load Banks. The SL Server Rack Heater Series is part of the dedicated line of load banks designed for data center commissioning. 
 
During data center design and construction, it is critical to test the HVAC cooling systems and the hot-aisle / cold-isle design. The SL20 is a 19" rack mountable air heater that simulates the heat generated by a server.  With adjustable load steps to 20 KW and variable airflow speed control, the SL20 can accurately mimic the different low and high power density servers available today.
