ACME Engineering Products Inc.
Acme manufactures gas detection systems for building ventilation control and indoor air quality. We also produce zero-emissions electric boilers—low and high voltage—for hot water and steam. Capacities range from 75 kW to 68 MW, with voltages from 480 V to 25 kV. With affiliates across India, China, Europe, Canada, the United States, and South America, we serve customers globally. Acme is ISO 9001 certified, meeting international standards. | Acme Engineering designs and manufactures gas detection systems, industrial process heating equipment, and automatic scraper-strainers for commercial and industrial applications. | The ACME’s automatic, self-cleaning strainers are used for water and wastewater treatment applications where the removal of suspended solids is critical for the protection of downstream equipment. Our scraper-strainer design effectively cleans under high solids loading and low-pressure conditions which backwash strainers cannot handle and subsequently clog up, requiring manual cleaning. ACME’s strainers are custom manufactured for each application to ensure a successful project. ACME is now capable of producing complete skid packages including pumps, controls, additional filtration products such as cartridge filters and all associated piping in its own ASME U-Stamp approved facility. We also offer process heating products, and gas and particulate detection equipment for environmental monitoring and control
