HL 112 Radiator Training Panel Show data sheet (pdf file) Print page
Technical Description

The panel contains a pipe system with four radiators. Each radiator has an air bleed, a thermostatic valve and lockshield valve.

  Rotameters indicate the flow rate through each individual radiator and for the entire system. Connections for cooling water make it possible to dissipate the heat supplied by the hot water. All water connections are made using quick-release couplings.

Learning Objectives / Experiments

- Hydronic balancing of radiators
- Determination of the heat emitted
- Determination of pipework characteristics for

  different operating conditions


In conjunction with other training panels in the HL 100 series, it is possible to set-up a complete heating system.


* Trainer for heating and plumbing1
* Adjustment of a heating system1
* In conjunction with other trainers in the HL 100

  series, assembly of a complete heating system is
