FRÖLING Unimatic 22-64 KW

Fröling – premium Austrian heating technology. The manufacturer from Grieskirchen develops heating solutions operating on cordwood, wood chips, and pellets.

Unimatic FV 50 – wood chip boiler, 1997. The original factory nameplate bears the designation "Hackgutheizkessel". The water content of the wood significantly influences the available thermal output.

• 22–64 kW nominal range: according to the specific Unimatic FV 50 nameplate.
• 64 kW with 20% moisture content wood: the original nominal point.
• 54 kW with 40% moisture content wood: the specifically stated output for wetter fuel.
• Wood chip version: the equipment of the feeder and fuel path must be coordinated in the specific system.
• 1997 manufacture: today's T4e control and automated cleaning cannot be retrofitted to the existing accessories of the old machine.

Documentation: exact FV 50 factory PDF is still missing. Operating pressure, water volume, and electrical data not readable on the nameplate cannot be replaced by a general FH-E diagram. Equipment offered for central wood chip heat supply.
