Overview
ENDOMATE™ Dual is a two-retort endothermic gas generator built for heat treatment lines that cannot tolerate an atmosphere interruption.
Where a single-retort generator forces a full shutdown for catalyst service or maintenance, ENDOMATE™ Dual runs one retort while the second stands by — or runs both together when the line calls for peak volume. The changeover is managed by the onboard controller, not by an operator.
Every cycle is logged: gas composition, dew point, energy consumption, and alarm history. That record is what your CQI-9 auditor asks for, and it is available without anyone transcribing a chart.
How It Works
Air and natural gas (or propane) are metered by an electronically controlled
proportioning system, then passed over a nickel catalyst inside a heated retort.
The reaction produces an endothermic atmosphere of approximately 40% H₂, 20% CO,
and 40% N₂ — the carrier gas used in carburizing, carbonitriding, and neutral
hardening.
ENDOMATE™ Dual applies this process across two independent retorts under a single
control system, with automatic mode selection based on demand.
Product Features:
Redundant dual-retort design — Run one retort with the second on standby, or both in parallel at peak demand. Catalyst service on one retort does not stop atmosphere supply to the line.
Unattended operation — Automatic start-up, mode switching, and shutdown sequences remove the need for a dedicated operator across shifts.
Demand-matched output — The generator adjusts production to actual furnace demand rather than running at fixed maximum, cutting both gas consumption and flare-off.
Electronic air-to-gas proportioning — Replaces mechanical ratio valves with electronic metering, holding the mixture stable as ambient conditions and supply pressure shift.
Full process traceability — Continuous logging of dew point, gas composition, energy use, and alarm events, exportable for CQI-9 and IATF 16949 documentation.

Layered safety interlocks — Flame supervision, over-temperature cutoff, gas pressure monitoring, and emergency purge, interlocked across both retorts.

FAQ
Q: What is the difference between a dual-retort and a single-retort endothermic generator?
A: A single-retort generator must be taken offline entirely for catalyst replacement or
retort maintenance, which stops atmosphere supply to the furnace line. A dual-retort
generator such as ENDOMATE™ Dual carries two independent retorts under one control
system, allowing one to be serviced while the other continues production.
Q: How much endothermic gas does ENDOMATE™ Dual produce?
A: 【待填】Nm³/h per retort, 【待填】Nm³/h with both retorts operating in parallel.
Q: Can ENDOMATE™ Dual operate without an attendant?
A: Yes. Start-up, mode switching, and shutdown run as automatic sequences, with
layered safety interlocks including flame supervision, over-temperature cutoff, and
emergency purge.
Q: What feedstock gases are supported?
A: Natural gas, propane, and LPG. Air-to-gas ratio is held by electronic proportioning
rather than mechanical ratio valves.
Q: Does ENDOMATE™ Dual support CQI-9 documentation requirements?
A: The generator logs dew point, gas composition, energy consumption, and alarm history
continuously. These records can be exported for CQI-9 and IATF 16949 process
documentation.
Q: Can ENDOMATE™ Dual be retrofitted to an existing furnace line?
A: Yes. 【待填：接口要求、场地要求、典型改造周期】
