Engineering & Statutory Overview

Turnkey Compliance Across Western Australia.

Industry Gas Services holds a full unrestricted Class I(A) Gasfitting Permit under Western Australian gas regulations, authorising our tradesmen to install, commission, and service Type B gas appliances and industrial fuel-fired equipment across any GJ capacity.

We work directly with plant engineers, equipment OEMs, and independent Type B inspectors to take custom, imported, and high-capacity gas-fired equipment from mechanical, gas piping, and plumbing installation through to final AS 3814 and AS 1375 approval with zero compliance bottlenecks.

Technical Capabilities.

Engineered Valve Trains

Assembly, modification, and pressure testing of double-block-and-bleed safety shut-off valve trains, proof-of-closure switches, gas pressure switches (high/low), air-fuel ratio controls, and leak detection systems.

Burner Management Systems (BMS)

Integration and functional testing of flame safeguards, UV/IR flame scanners, ionization probes, purge timers, safety interlocks, and emergency stop circuits.

Appliance Conversion, Retrofits & Upgrades

Upgrading legacy industrial burners and non-compliant imported equipment to meet current AS 3814, AS 1375, AS/NZS 5601.1, and AS/NZS 1596 safety requirements, including fuel conversions across Natural Gas, LPG, and Biomethane.

Ventilation, Flueing & Interlock Verification

Ensuring forced-draft, induced-draft, and natural-draft flueing systems are mechanically interlocked with the appliance safety circuit to prevent unsafe firing conditions.

Inert Purging & Combustion Commissioning

Safe pre-commissioning line purging, air-fuel ratio tuning, flue gas emissions analysis (CO, O₂, CO₂, NOₓ), and coordination with accredited Type B appliance inspectors for final sign-off.

Specialist Appliance Applications.

We have specialized expertise across custom and high-demand thermal equipment, including:

Incinerators & Thermal Oxidizers

Medical, quarantine, agricultural, and industrial waste incinerators, afterburners, and volatile organic compound (VOC) abatement units.

Cremators

High-temperature human and animal cremators, secondary combustion chambers, and automated temperature/draught control trains.

Smoke Ovens & Commercial Food Processing

Industrial smokehouses, curing ovens, bakery tunnel ovens, steam boilers, and thermal fluid heaters.

Commercial Coffee Roasters

Custom and imported drum and fluid-bed coffee roasters, catalytic afterburners, chaff collectors, and gas train compliance upgrades.

Stationary Gas Engines & Turbines

Fuel gas supply trains, pressure regulation, knock-out pots, filtration, and safety shut-off systems for stationary reciprocating gas engines, generators, and compressors.

Mining & Metallurgical Kilns/Furnaces

Assay furnaces, gold elution heaters, drying kilns, and smelting pre-heaters across regional WA mine sites.
