What this manufacturer offers
中山市英纳尔制冷科技有限公司 describes itself as a specialist producer of finned heat exchangers serving domestic air conditioning, heat-pump/pool equipment, precision air conditioning and mobile air conditioning. Its official contact page identifies a factory address at 28 Caihong Road, Haigang Village, Shenwan Town, Zhongshan.
The website offers more useful manufacturing context than product ratings: tube/fin tooling patterns, tube-processing capability images and an original process-flow chart. The precision-air-conditioning category itself contains three image labels rather than named, rated models. Manufacturing capability should therefore be reviewed separately from the selected coil’s thermal output and connection fit.
An original municipal safety-standardisation notice names this entity in a 2024 list. The displayed industrial production licence has a past expiry. Those different records are described by their actual scope below; neither supplies an independently verified heat-transfer result.

03 / PROJECT REVIEW
Evaluate Yingnar as a coil manufacturing partner, with a defined OEM brief
Start with the OEM application and the component’s responsibilities
The official introduction distinguishes coils used in domestic, heat-pump/pool, precision and mobile air-conditioning equipment. The precision category has three product-image captions, IMG_6000, IMG_1953 and IMG_1952. Those filenames are not model identifiers or refrigerant specifications.
For an OEM development project, explain whether the supplier is manufacturing to your drawing or making a thermal/mechanical selection. Define responsibility for circuit design, materials, connections, casing and testing. Supply the equipment envelope and operating conditions rather than selecting solely from an application-category photograph.
Build to an existing design
Provide controlled drawings, circuit details, interface tolerances, materials and acceptance requirements; have deviations approved before samples.
Coil selection support
State air-side and fluid/refrigerant duty, space/pressure-loss constraints and the required output; request a documented proposed selection.
Replacement or revised coil
Identify the original assembly and essential interfaces, with the revised duty/operating limits; a similar image does not prove interchangeability.
Tooling patterns are useful manufacturing questions, not complete model ratings
The company introduction says it has eight production lines and lists tooling entries using 5, 7 and 9.52 tube diameters with different pitch patterns. For Ø7×21×18.19 it lists both a 30-column/two-step and a 42-column/four-step tool. That is a tooling/production distinction, not two automatically equivalent finished coils.
The processing-capability page contains actual horizontal/vertical expansion tables, long/short U-tube information, copper fitting photographs and five fin-pattern examples. Confirm which tooling, usable rows/holes/lengths and process apply to the selected drawing. Do not combine separate machine limits into one maximum coil envelope or transfer a tooling tuple into a product performance claim.
Documented tooling catalogue
Different Ø5/Ø7/Ø9.52 patterns are published, with distinct tool column/step counts in the introduction.
The process chart identifies checkpoints but not the delivered test result
The original flow card shows long-U bending, fin punching, tube insertion, expansion, degreasing/drying, insertion of fittings, nitrogen charging, automatic/manual joining, internal blowing, assembly, a pressure/water-bath inspection, drying, barcode marking and packing. Expansion and pressure/water-bath inspection are marked as key processes. A leaking-item branch returns through repair and repeat inspection.
The chart provides a concrete basis for asking about process control. It does not supply numerical test pressure, hold time, leak acceptance, instrument calibration or a record for your batch. Agree the relevant materials, cleanliness, joining and test requirements on the selected coil, including identification and inspection records after any rework. Do not substitute the general chart for a model-specific acceptance certificate.
Review stated scale against the actual programme’s capacity
The official introduction claims more than 150 employees, 15 professionally qualified personnel, 30 staff with college-level or higher backgrounds, eight heat-exchanger lines and annual capacity of five million pieces/sets. It also gives an annual-value headline. These are supplier statements without an independently inspected current production schedule or a definition of one production unit.
For a new OEM programme, ask which line/tooling will be allocated, sampling and first-article capacity, production cycle, lot sizes and change-control arrangements. A headline across several applications does not establish spare capacity for a particular circuit, geometry or launch date.
Use the municipal safety record within its stated scope
The Zhongshan Emergency Management Bureau notice, published on 12 April 2024 and dated 10 April 2024, announces the third batch of level-three work-safety-standardisation enterprises. Row 125 identifies 中山市英纳尔制冷科技有限公司, Shenwan Town, mechanical industry, certificate AQBⅢGM(粤)ZS20240255 and a table expiry of 10 April 2027.
This is an original enterprise work-safety record. It is not a coil efficiency test, pressure-product approval, factory-capacity audit or a fresh confirmation that no status change has occurred. The notice’s broad three-year wording and the table’s exact expiry are preserved as published rather than recomputed.
What the original notice names
The exact entity, district/industry and listed work-safety-standardisation certificate/expiry.
Any particular precision-AC coil’s duty, refrigerant, materials, design pressure, leakage or operating efficiency.
The old production-licence image is a historical document
The actual official-gallery licence image names the company, the Caihong Road address, refrigeration equipment with details in a subsidiary document, certificate XK06-015-02015, issue date 23 June 2017 and expiry 22 June 2022. No current renewal or full subsidiary scope was authenticated.
The gallery also lists honours and a high-technology-enterprise image, but the captions do not establish current model certification. Request current readable documents and their exact entity/site/product scope where applicable. Confirm the selected order’s inspection separately. The reviewed pages establish no fixed MOQ, price, lead time or detailed warranty duration; those should be written into the approved offer.
Qualify the sample
Approve the drawing revision, materials/circuit, dimensional report and agreed test evidence before production release.
Control production changes
Agree permitted tooling/process substitutions, lot identification, inspection release and handling of reworked items.
Confirm the commercial handover
Record packaging and end protection, sample/production timetable, written warranty and the party responsible for installation into the final equipment.
