Results of Operations

   1.                                                   We note from your
disclosure in Note E that a significant amount of your revenue is
                                                        generated from
long-term fixed price contracts that is generally recognized over time
                                                        utilizing the
cost-to-cost method. Under the cost-to-cost method, the extent of progress
                                                        towards completion is
measured based on the ratio of costs incurred to date to the total
                                                        estimated costs at
completion of the performance obligation. We also note your
                                                        disclosure that for the
years ended September 30, 2022 and 2021, your operating results
                                                        were positively
impacted by $ 11.3 million and $ 12.5 million, respectively, as a result of
                                                        changes in contract
estimates related to projects in progress at the beginning of the
                                                        respective period.
Please revise your results of operations disclosure in MD&A to
                                                        separately quantify
gross favorable and gross unfavorable changes in estimates material to

         your results, accompanied by an appropriate level of analysis.
2.       We note your disclosure that gross profit increased by 13%, or $10.0
million, to $85.0
         million in fiscal 2022, but despite the increase in revenues, gross
profit as a percentage of
         revenues remained flat to the prior fiscal year at 16% in fiscal 2022
due to increased costs
         impacting older projects in your backlog that were subject to
inflationary pressures on raw
         materials and components, with little or no recourse from the customer
to reprice the
         project. We also note that favorable project execution, volume
leverage and product mix,
         including fast track service and replacement projects across your
service division, all
         helped to offset the negative inflationary pressure carried by the
older projects in the
         backlog. In future filings where you describe two or more factors that
contributed to a
         material change in a financial statement line item between periods,
especially when there
         are offsetting amounts, please quantify each material factor that
contributed to the overall
         change in that line item. Refer to Item 303 of Regulation S-K and
Section III.D of SEC
         Release No. 33-6835.
Consolidated Statements of Operations, page 33

3.       We note from your disclosure in Note E on page 43 that in addition to
manufacturing
         custom-engineered products and systems, you recognize revenue from
contracts to
         provide field service inspection, installation, commissioning,
modification, and repair
         services, as well as retrofit and retrofill components for existing
systems. We also note
         from some of the discussion during the year end 2022 earnings call,
that this service
         revenue was a significant contributor to your business during 2022.
Please tell us the
         amount of revenue related to services as compared to products for the
year ended
         September 30, 2022. If the amount is greater than 10% of the
consolidated revenue
         amount, please revise future filings to separately present revenue and
cost of goods sold
         for products and services. See requirement in Rule 5-03(b)(1) and
(b)(2) of Regulation S-
         X.

4.       We note that your Key Highlights section at the top of your earnings
release includes the
         disclosure of your book-to-bill ratio. Please disclose how you compute
the book-to-
         bill ratio and explain the significance of this ratio in understanding
your business. As part
         of your disclosure, please define "new orders" and disclose any
limitations on the new
         orders amounts, such as any pertinent termination clauses or
contingencies, that may
         ultimately impact the realizations of such amounts as revenues. Refer
to the metrics
         guidance set forth in SEC Release No. 33-10751.
       In closing, we remind you that the company and its management are
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review,
comments, action or
absence of action by the staff.
