Antagus Engenharia

What Antagus Engenharia does

Antagus Engenharia is a privately held Brazilian engineering firm headquartered in Rio de Janeiro (Barra da Tijuca) that specializes in tank gauging systems for the oil and gas sector and related custody transfer applications. The company was founded approximately in 1992-1993 and operates with a lean team of 5 employees, serving the entire Brazilian national territory through direct sales. Its core product portfolio is built around three exclusive distribution partnerships: Exalon Delft temperature interfaces (the X62T series — MIT, VT, MIR, MPT) that serve as drop-in replacements for discontinued Honeywell Enraf 862-series transmitters; the Precision Digital family of process meters, displays, and alarm announciators (Trident, ProVu, Loop Leaders, ProtEX, ProtEX MAX, Helios, VantageView, ConsoliDator, Sabre, Nova, Survivor, PDW Wireless, Vigilante II, MINUMUX II); and Aquasant-MT impedance-based automatic drainage and oil/water interface detection systems.

Underlying technologies include non-intrusive ultrasonic sonar level measurement (installed on tank bottom plates, achieving 0.1% accuracy and unaffected by gas or product clouds), impedance-based water-oil interface detection (Bar probe and Ring probe with MIQ electronic control unit for automatic drainage), and multi-segment capacitance sensors with multi-point PT-100 temperature measurement for custody transfer uncertainty below 1 mm. The X62T interfaces are ATEX-certified for Zone 0/Zone 1 hazardous-area installations, addressing the regulatory requirements of Brazilian refineries and terminals.

Antagus generates revenue through three streams: hardware sales (tank gauging instruments, temperature interfaces, ultrasonic level meters, alarm announciators, and automatic drainage systems sourced from represented manufacturers), technical services (project design, installation, start-up, commissioning, testing, and training), and maintenance and repair services (preventive and corrective maintenance for Enraf and SAAB level gauges, electronic module recovery, technical support, and 24/7 emergency maintenance contracts). The company is also an authorized service provider for Honeywell Enraf and Emerson Rosemount SAAB radar systems (REX2900, REX3900, REX PRO, RAPTOR5900), enabling calibration, integration, and training services for custody transfer applications. Pricing is contact-based with no public disclosure, and go-to-market is direct sales-led with no online commerce presence.
