SIASUN GCR25-1800-EX (GCR25-1800-EX)

In a refinery or chemical plant, the tasks that carry the greatest risk are often the ones still carried out by hand: drawing a sample from a line, operating a valve where vapour may gather, moving containers close to a reactor. The SIASUN GCR25-1800-EX is designed to take that place instead of a person. It carries the highest payload in SIASUN's Explosion-Proof Series, combining 25kg of payload with 1800mm of reach on a six-axis collaborative arm. It also keeps the straightforward teaching and built-in safety logic that make collaborative robots practical on a working site.

Robots Europa, based in Dublin, sells the SIASUN GCR25-1800-EX and supplies it to customers throughout the European Union and the DACH region. Our team prepares each quotation against your specific application, arranges delivery to your site and remains your point of contact for technical support after commissioning. This applies whether the robot is intended for a single pilot cell or a rollout across several plants.

Background

SIASUN and the DUCO sub-brand

SIASUN DUCO is the sub-brand of SIASUN dedicated to intelligent robotics. The company states that it has broken foreign technology monopolies in several fields and that all of its core components are developed in-house. For a buyer, that vertical integration means the arm, its control and its software come from a single engineering source rather than being assembled from third-party modules. The Explosion-Proof Series is the part of this range aimed at industries where an ordinary robot cannot be used.

A collaborative arm for hazardous areas

The Explosion-Proof Series comprises four collaborative robot models, covering load capacities from 10 to 25 kg and arm reaches from 1300 to 2000 mm. SIASUN positions the series as a protective barrier for frontline workers. These robots can replace human operators in flammable, explosive, toxic, harmful, high-temperature and high-pressure settings of the kind found in the petroleum, natural gas and chemical industries. Within that line-up, the GCR25-1800-EX sits at the top for payload. Its 1800mm reach allows it to serve a broad working envelope from a single mounting point.

What distinguishes the series from conventional heavy industrial robots is that it retains the character of a cobot. Operators teach the arm by drag-and-drop teach programming, guiding it by hand rather than writing code line by line. The arm carries 16 TÜV-certified safety features for human-machine collaboration, and it integrates 2D/3D vision depth fusion with high-sensitivity force perception and control.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

SIASUN has not published the weight, the explosion-protection rating, the power supply or power consumption, the robot's dimensions, the operating temperature range, the communication and I/O interfaces, the joint ranges and speeds, the required air supply or the contents of the box; Robots Europa confirms these at quotation.

What makes the GCR25-1800-EX different from the other Explosion-Proof models?

All four models in the series share the same purpose and the same collaborative foundations. What separates them is the balance between payload and reach. The GCR25-1800-EX carries 25kg, the top of the series' 10 to 25 kg payload range. That matters when the end effector itself is heavy, as with a valve actuator, a gripper for drums or containers, or a tool combined with a camera and a force sensor. Every gram of tooling is subtracted from the load the arm can still move.

Its 1800mm reach is generous without being the longest in the series, which extends to 2000 mm. A project that needs the furthest possible reach, or one that handles lighter parts and benefits from a more compact arm, may be better served by a sibling model. A project that needs to lift substantial loads across a wide working area points to the GCR25-1800-EX. Combined with a repeatability of ±0.05mm and a maximum TCP speed of 2.5m/s, the arm is suited to tasks that need both strength and precise, repeatable positioning.

Why does an explosion-proof cobot need vision and force sensing?

Hazardous-area tasks rarely take place in the tidy, fixtured conditions of a production line. Valves, flanges and containers are not always where a programme expects them, and a robot that simply replays a fixed path can fail or cause damage. The 2D/3D vision depth fusion lets the GCR25-1800-EX locate objects in three dimensions. High-sensitivity force perception allows it to feel contact, so it can seat a connector, turn a handle or detect resistance rather than forcing a movement through.

The software side supports the same aim. Scenario-specific software packages shorten the path from installation to a working application. Cloud-based data monitoring gives engineers a view of the robot's condition without entering the hazardous zone themselves, and remote OTA upgrades keep the control software current without a site visit. Drag-and-drop teaching means that process specialists, not only robot programmers, can adapt the arm to a new task.

Who is the GCR25-1800-EX for?

The primary buyers are operators in the petroleum, natural gas and chemical industries who want to reduce the exposure of their staff to flammable, explosive, toxic or high-pressure environments. These include refinery maintenance teams, gas processing facilities, chemical producers and storage terminals, as well as the engineering contractors who design and modernise such plants. System integrators building automated cells for hazardous areas form a second group, since the arm's interfaces and software packages give them a platform to work from.

The GCR25-1800-EX is the right choice when payload is the deciding factor. Where the load is lighter, or the layout calls for a different balance of reach and payload, the other models of the series deserve comparison: the SIASUN GCR10-1300-EX, the SIASUN GCR16-2000-EX and the SIASUN GCR20-1400-EX. Buyers who do not need explosion protection can browse our wider range of Robot Arms.

What is the GCR25-1800-EX used for?

1. Valve operation: opening and closing valves in zones where flammable gas or vapour may be present.
2. Sampling: drawing product samples from process lines without sending an operator into a toxic area.
3. Container handling: moving heavy containers, drums or tools with a payload that leaves room for substantial tooling.
4. Visual inspection: using 2D/3D vision to check equipment and locate parts in unstructured surroundings.
5. Connection tasks: coupling and uncoupling hoses or connectors with force-controlled, sensitive movements.
6. Work near heat and pressure: carrying out routine handling close to high-temperature or high-pressure equipment instead of a person.
