Accounting Standards Update and Change in Accounting Principle [Abstract]
New Accounting Pronouncements	In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which is intended to enhance the transparency, decision usefulness and effectiveness of income tax disclosures. The amendments in this ASU require a public entity to disclose a tabular tax rate reconciliation, using both percentages and currency, with specific categories. A public entity is also required to provide a qualitative description of the states and local jurisdictions that make up the majority of the effect of the state and local income tax category and the net amount of income taxes paid, disaggregated by federal, state and foreign taxes and also disaggregated by individual jurisdictions. The amendments also remove certain disclosures that are no longer considered cost beneficial. The amendments are effective prospectively for annual periods beginning after December 15, 2024, and retrospective application is permitted. Although the ASU only modifies the Company's required income tax disclosures, the Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, which requires additional disclosure of the nature of expenses included in the consolidated financial statements. The effective date of this ASU is for annual periods beginning after December 15, 2026. The Company is evaluating the effect this guidance will have on the consolidated financial statements.
Revenue Recognition	The Company recognizes revenue from the sale of its products when obligations under the terms of a contract with our customers are satisfied; this occurs with the transfer of control of our products and replacement parts or throughout the completion of service work. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring promised goods or services to a customer and excludes all taxes collected from the customer. Shipping and handling fees are included in Net sales, and the associated costs are included in Cost of sales in the Condensed Consolidated Statements of Operations. For shipping and handling costs that occur after the transfer of control, the Company applies the practical expedient and treats such costs as a fulfillment cost. Incidental items that are immaterial in the context of the contract are recognized as expense.

Disclosure of accounting policy for revenue from contract with customer.
