The Garner Underground Inc. (GUI) was established in 2014 as the product development arm for its sister companies, EBTRON and GreenTrol Automation. EBTRON and GreenTrol are leaders in instrumentation and control for today’s rapidly growing HVAC and agricultural markets. GUI will also provide services to customers outside of the EBTRON/GreenTrol family when the proper opportunity arises.
Product design is typically microprocessor-based with embedded firmware and application software. Most products have short development time-cycles and our design team handles all aspects of product development from inception to production.
