Server Rack Heaters
The Trystar SL Server Rack Heater Series is built for data center commissioning, enabling precise testing of HVAC systems and hot-aisle/cold-aisle designs. The SL20 model is a 19″ rack-mountable air heater that simulates server-generated heat with adjustable load steps up to 20 kW and variable airflow speed control. With a resolution as low as 500W, it can accurately mimic both low- and high-density servers. Lightweight at just 43 lbs, it’s easy for one person to handle, and its 10U design with locating pins and locking tabs ensures quick installation. Featuring illuminated load step controls, fan speed adjustment, over-temp indicators, and digital metering, the SL20 delivers accurate, reliable, and efficient thermal testing.
