Eclipse thermostatic inserts

Thermostatic inserts with automatic flow control for radiators with integrated valves

The Eclipse thermostatic inserts are suitable for all HEIMEIER thermostatic heads and actuators. The required flow rate can be adjusted directly at the Eclipse thermostatic insert with a twist. The adjusted flow will not be exceed even if there are load changes in the system, due to other valves closing or during morning start up. The valve controls the flow rate independently from differential pressure. Therefore, complicated calculations to determine settings are not necessary.
