Turnkey Third-party Gas Appliance Testing Laboratory: A 22-unit Order for Inner Mongolia

For Beijing Chenyuan Kesheng Technology, Wanhe delivered a complete third-party gas-appliance testing laboratory as one 22-unit order for an Inner Mongolia project – gas flexible-hose rigs, cooktop performance and durability systems, valve and thermocouple endurance, tightness stations and electrical safety.

Third-party and certification laboratories need breadth as much as depth: they test many product categories, not one. This project was a full lab build-out for Beijing Chenyuan Kesheng Technology, a gas-appliance testing organisation, delivered as a single coordinated Inner Mongolia order of 22 units. It is the clearest example of our gas appliance test bench capability as a one-stop supplier.

1. Why a one-order lab build-out

A third-party lab does not buy machines one at a time – it needs a coherent set covering the categories it will certify. The 22-unit order grouped four clusters: gas flexible-hose testing, cooktop performance and durability, gas-component endurance, and electrical safety. Planning, drawings, manufacturing and commissioning were coordinated as one project so the lab could certify across product families from day one.

2. The gas flexible-hose test cluster

The largest sub-group was the WH-GL08 gas-hose test family: joint impact resistance (WH-GL08-102), hose impact resistance (WH-GL08-111), pressure resistance (WH-GL02-106), vibration resistance (WH-GL08-112), torsion (WH-GL08-103), tube torsion (WH-GL08-120), tightness (WH-GL08-107), bending (WH-GL08-108) and coating breathability (WH-GL08-119), plus a purchased tensile tester (WH-GL08-105). Effectively a complete gas-hose validation suite in one project.

3. Cooktop and durability cluster

The remaining units covered cooktop combustion performance (WH-ZJ01-400A comprehensive system, WH-ZJ01-428 valve-flow), and the full set of endurance rigs: whole-cooktop life (WH-ZJ01-402A), igniter durability (WH-ZJ01-405B), thermocouple durability (WH-ZJ01-415B), stopcock valve durability (WH-ZJ01-418), flame-failure protection durability (WH-ZJ01-401B), dry-boil protection endurance (WH-ZJ01-420) and solenoid valve durability (WH-ZJ01-407B). Tightness coverage included WH-ZJ01-416B. Thermal-efficiency related work can be cross-referenced to our thermal efficiency test system.

4. Electrical safety and commissioning

The order closed with an electrical performance test bench (WH-AQ22-101) and a DJ-68 spark leak detector for non-destructive leak checking. Multi-unit projects like this are planned, built and commissioned together, with fixtures and gas/water services coordinated so the lab goes from crates to certification work without piecemeal integration.

Frequently Asked Questions

Can Wanhe supply a complete lab rather than single machines?

Yes – this 22-unit order for Beijing Chenyuan Kesheng covered hose, cooktop, durability, tightness and electrical clusters as one coordinated Inner Mongolia project.

Does the gas-hose cluster cover the main validation items?

The WH-GL08 family delivered covers joint/hose impact, pressure, vibration, torsion, tube torsion, tightness, bending and coating breathability for gas flexible hoses.

Which endurance rigs are included?

Whole-cooktop life, igniter, thermocouple, stopcock valve, flame-failure protection, dry-boil protection and solenoid valve durability rigs are all part of the order.

Do you support commissioning of the whole lab?

Yes – multi-unit projects are planned, built and commissioned together, with fixtures and gas/water services coordinated on site.

Engineering and site integration

Building a whole laboratory at once means coordinating drawings, services and delivery slots before any machine leaves the factory. For the Beijing Chenyuan Kesheng Inner Mongolia project, we grouped the 22 units into four installable zones – hose testing, cooktop performance, durability, and electrical safety – and routed the shared gas, compressed-air, exhaust and water services between them on a floor layout drawn with the customer. Each bench is factory-burned-in before shipment, and on site we install, connect services, commission zone by zone, and run sample parts on each machine before sign-off. Because the lab serves outside customers, calibration certificates, operation manuals in Chinese and English, and a spare-parts list are delivered with the acceptance report. This is the same one-responsible-vendor model behind our custom test solutions.

How a custom bench is specified

When a customer comes to us for a bench like the ones in this case study, the first working exchange is a short questionnaire rather than an instant price: we ask for the product drawings and range of models, the test clauses or standards the bench must satisfy, the required production beat or throughput, the local gas type and pressure, and the on-site utilities (compressed air, water supply and drain, power, exhaust). From that we issue a block diagram, a floor-layout sketch, a station list and a proposed acceptance checklist, then refine the fixture design together before fabrication begins. Every machine goes through a factory acceptance run with a sample part before shipment, and on-site commissioning is carried out with the customer’s engineers present. This front-loaded specification step is why retrofits – such as the Ferroli valve-circuit upgrade and the Geyou single/dual conversions – can reuse existing frames without surprises.
