The Company alone and with strategic partners has an active internal R&D program to expand the potential markets for BioBlower technology, refine the system components to reduce size, weight, and the capital cost and also to improve system efficiency to reduce the operating costs
Much of the Company’s internal R&D is focused on improving the performance of the heat exchanger component. The heat exchanger controls the operating costs of a BioBlower system, because it determines the energy required to operate the system and the size and cost of other components, e.g. the motor.
A highly effective heat exchanger recycles almost all of the energy used to sterilize the air and heat the catalyst. A traditional plate/fin heat exchanger can recycle as much as 95% of the heat energy, but a primary surface heat exchanger can recycle as much as 98% of the heat energy, reducing the operating cost by more than half.
The heat exchanger is also the most expensive component in the BioBlower system. Because of its simplicity, a primary surface heat exchanger is smaller, lighter and is much less costly (as much as an order of magnitude less expensive) to manufacture than a traditional plate/fin heat exchanger.
The drawing below shows the plate/fin, counter flow heat exchanger used in our 5,000cfm prototype. We expect to develop primary surface heat exchanges for use in most of our future products.
