TECHNICAL DATA FOR THE XRGI® 15 LowNOx
Product data sheet in accordance with Regulation (EU) No. 811/2013; 813/2013, Dated 26.09.2019

The XRGI® is a combined heat and power plant (CHP) that works on theprinciple of cogeneration.
An XRGI® system consists of three main components – the Power Unit,
Q-Heat Distributor and the iQ-Control Panel.
In addition, you can also extend your XRGI® system with a storage tankwith a capacity of 500, 800 or 1,000 litres for optimum operation.

TECHNICAL DATA FOR THE XRGI® 15 LowNOx + FLOW MASTER(Temperature control, Class II = 2 %)Product data sheet in accordance with Regulation (EU) No. 811/2013; 813/2013, Dated 26.09.2019

Figure shows FM type 350

The Flow Master including Flow Master Control regulates the supply of heatfrom the XRGI® and from the storage tank to the consumer network. Thistechnology enables a significantly higher heat output to be temporarily
made available to the consumer side. This allows peaks of heat demand tobe handled by the XRGI®, thereby extending its service life and increasing
electricity production.
The 4 models can deliver a heat output of 50, 150, 250 or 350 at a ∆T of 20 K.
