02 June, 2026

New product: LK 868 HeatExchanger 125

We are introducing LK 868 HeatExchanger 125, a pre-insulated heat exchanger developed for simple connection to LK HydronicGroup H/C 125.

The product is designed for installations where media separation is required, for example in free cooling installations where antifreeze should be kept out of the heating system, or in older systems where oxygen ingress may affect the heat source.

With its 125 mm connection distance, LK 868 HeatExchanger 125 enables quick and smooth installation together with LK HydronicGroup H/C 125. It also offers connection options for mounting a safety group on the secondary side of the heat exchanger.

LK 868 HeatExchanger 125 is available in two capacities: 15 kW and 30 kW.
