Aquaculture – the GeoExchange Way

Lockhart Industries has designed and installed refrigeration systems for commercial clients throughout Vancouver Island, BC. The most rewarding  and largest challenge that we’ve accomplished has been the chilling and heating of water for salmon-rearing aquaculture  facilities. Lockhart Industries engineered a way on our first 150USgpm design to save up to $100,000 USD operating cost in four months, thus facilitating  less than a one-year payback on these custom designed systems. We pioneered  these unique custom designed heating and chilling units (GeoExchange)  on the West Coast and continue to improve our product quality and lower operating costs. We use the same equipment  to chill eggs and then subsequently warm the fry. This allows for greater versatility of first feeding as well as greatly accelerating  their growing while lowering mortality. Adding DOC controls to the Aquaculture GeoExchange heat pump systems is a way to enhance product quality, optimize energy consumption and extend equipment life. This enhancement facilitates  the very close control of the biomass and optimization  of energy consumption. These systems can also be tied into spread sheets to trend the performance of the system to performance of the biomass.
