These heat recovery systems utilise excess hot water from the distillation process to dry the malted barley, removing the need for burning coke; but requiring no changes to the use of peat which adds the unique, subtly smoky flavour to the spirit. The original axial fans in the kiln roofs have been supplemented with new high efficiency radial fans, which now blow heated air up through the grain bed.

Heat is transferred from the distillery to the kiln air stream using modern stainless steel heat exchangers, one steam and one hot water heat exchanger for each kiln. The process air is transported in long-lasting stainless-steel ducting. One kiln also has the facility to recycle air during the later stages of drying to further reduce energy usage.

DVE has enjoyed working with Highland Park and feel proud to have delivered a major projectfor an iconic brand.
