The basic functions of the DL3 are very simple. 2 ventilating fans are responsible for the suction of cool air. The air is conducted through an 80 cm long square tube containing a heating element. The warm air is expelled accordingly to the specifications.

The 19” front cover (4 HE) of the DL3 with control and fans. The DL3 is activated by a 2 stage switch: Stage 1 activates ventilating fans, stage 2 switches heating on. The LEDs indicate the operational status of ventilation and heating.

DL3 with attached diffuser. Waste heat can be conducted specifically in order to achieve a more realistic heat load distribution comparing to non-directional venting.

19" Load resistance

With the DL3 you will have a reliable performance check tool for your data center


The DL3 acts in the same way by contributing an IT power uptake of 3 KW per unit. But it goes a step further. The DL3 is designed according to the 19" technique so that the waste heat is generated in the spots corresponding to real working conditions with real IT equipment. This is a big advantage, because only in this fashion you can make a reliable assessment about the efficiency of your cooling system for all pertaining areas.

To simulate for e.g. an IT power intake of 120 KW, rack spaces will be fitted with 40 DL3 and their distribution pattern will be chosen according to real operational conditions. By activating DL3 units individually it is possible to generate load situations under controlled conditions between 3 – 120 KW in order to analyze its effect.

Thus, the DL3 is an important tool to check the efficiency of your data center. No IT manager should be without such test possibilities!
