Technology makes the difference

Powerful, demand-oriented and safe

For increased power requirements, HDG heating systems can be combined with each other in a cascade configuration. The advantages of a cascade solution are, for example, the high power range, maximum operational reliability and demand-oriented heat supply, especially when energy requirements fluctuate. With HDG, a cascade consists of two boilers that load into a common accumulator.

The HDG Compact cascade thus combines the potential of a boiler from the large power range with the unrivalled flexibility of a multi-boiler system.

Perfectly adapted to the heat demand

A cascade adapts perfectly to the heat demand. When there is a high demand, both boilers run. When demand is low, only one boiler is switched on alternately. Alternating operation reduces the operating hours per boiler and the thermal load decreases. This increases the life expectancy of the installed components.

Clever HDG cascade management

Using the HDG accumulator management system, the installed boilers are alternately assigned the role of lead boiler. Due to the completely autonomous operation of both boilers, the failure of one boiler has no effect on the operation of the second boiler.

Service during operation

The necessary maintenance can take place during operation, as the second boiler continues to run anyway. In addition, the HDG cascade offers maximum safety: If one boiler is not working, the second boiler takes over the basic supply for the connected heating components.

Use the entire tree with HDG!

Until now, burning wood chips from branches, treetops and thinning wood has been difficult. Things are different with HDG: Thanks to the Vario delivery system and integrated fine dust separator, coarse and ash-rich fuel can now also be used.

Integrated fine dust filter

With our fine dust separator technology, fuels rich in ash can also be used. Due to the integration in the boiler, only 5 cm more space is required. All fine dust particles are cleaned and collected fully automatically and conveyed to the central ash container just like the other combustion residues.

The advantages:

  • Use of high-ash fuels from forest residues
  • Electrostatic separator guarantees lowest fine dust values – from heating up
  • until burn-out
  • Thanks to complete integration in the boiler only about 5 cm
  • additional space required
  • Fully automatic cleaning system of the electrode and separator surfaces
  • Integrated filter ash removal of all residues into the ash container
  • Low flue gas pipe connection – ideal for existing fireplaces

From the warehouse to the boiler

Flexible delivery system and feeding technology for every area of application

A sophisticated delivery and feeding system is crucial for the safe and reliable operation of an automatic wood heating system. With clever innovations, the new HDG Vario system sets standards here.

  • Cut-Connection: Huge transfer opening between the auger and the rotary feeder reliably prevents material blockages
  • 4-chamber rotary feeder: Combines absolute back burn protection
  • with minimal component stress due to low friction surfaces
  • Stoker auger with dosing container: The fuel dosage via light barrier guarantees an even material supply and constant output even with different fill levels in the warehouse

In addition, with several delivery systems for wood chips (flexi blade delivery system, hinged arm delivery system, walking floor delivery system, etc.) and pellets (suction system, auger delivery system), solutions are also available for fuel transport for every application.
