Design Features

Long Fire Zone

  • Enables a greater variety of fuels and clays to be used.
  • Allows for optimal combustion and energy extraction from fuel sources. 


  • Allows for the brick making season to be prolonged into the monsoon season (increase annual brick production).
  • The masonry is protected and therefore high energy costs associated with drying out wet kilns after every monsoon is eliminated.
  • Decrease costly repairs required from monsoonal damages.
  • Kiln workers are protected from the elements, working conditions are improved both day and night.                                   
  • Allows for water collection (drinking and sanitation).
  • Solar panels can be fitted/mounted to the roof and used to as a source of power for kiln operations i.e. fan and lighting.

Archless Design

  • Removal of large masonry arches in the design, decreases construction time.
  • Decrease construction costs.
  • Simplifies kiln maintenance.
  • Kiln is easily mechanised to allow for larger brick production i.e. fork lift access, for the setting and removal of bricks.

No tall Chimney

  • Not needed as draught is created through use of induced draught fan.
  • Decrease construction costs.
  • Decrease construction time.
  • Exhaust gases and vapour are minimised through near complete combustion, minimal emission creations are then released via a low, small chimney made of brick or iron which extends a short distance above the roof line.

Scalable Operating Mode

  • Options to operate in both a continuous or semi-continuous mode, allowing for smaller or larger outputs depending on operators requirements i.e. large scale (industrial) or small scale (village/rural setting). 
  • HZZK design is highly appropriate for clamp kiln replacement.
  • Flexibility in the source of power to drive the fan.
  • Kilns can operate successfully without access to the electrical grid.
  • Diesel or solar can be used as source power, when access to electrical grid unavailable.
  • Kiln has the smallest construction footprint (size), compared to other kilns.
  • Brick production requirements (output demand) determines the size/footprint of the kiln i.e. an increase or decrease in the number of kiln chambers.

Progressive mechanisation is easily accomplished

  • Kiln design can be altered to allow for use of forklift setting and removal of fired bricks.
  • Doors/wickets can also be altered in their size and sealing mechanisation, depending on kiln requirements and brick demands.
  • Increase in mechanisation/machine automation systems reduces handling of bricks and reduces risk of associated damage.
  • Automatic fuel feeders can be incorporated into the kilns design, enabling mechanised fuel distribution.

Habla Kilns wins 2017 UNAA Business Climate Action Award

Habla Kiln's successful application of clean, clay brick firing technology in an overseas setting has made it the inaugural winner of the 2017 UNAA  (United Nations Association of Australia) Business Climate Action Award.
