01 / COMPANY
What this manufacturer offers
Henan Tongzhou Refrigeration and Air Conditioning Equipment Co., Ltd. is a Jiaozuo manufacturing lead for assembled refrigeration equipment. Its official displayed business licence identifies 河南同舟制冷空调设备有限公司, credit code 91410822MA9G43A877 and establishment on 3 December 2020, matching the preserved CRM source. The displayed licence bears a 22 January 2026 issue date; it is a document on the supplier website, not a fresh registry audit. The registered address at No. 8 Weisan Road/ Yingbin Avenue, building 06 differs from the official contact location inside the Xiaozhongli vehicle-service/parking logistics park. The latter matches the preserved latest annual-report and correspondence addresses.
The company describes production and assembly of screw, reciprocating, high/medium/low-temperature units and refrigerant pump packages. The most useful inspected technical page is its low-pressure vessel/canned-pump assembly. Several newer evaporative and three-parallel product pages contain only names and photographs, so their ratings and compressor arrangements remain unverified. This profile uses the matched identity and actual circuit information to prepare a supplier evaluation; workshop scale, throughput and pressure-vessel manufacturing approval are not established.

03 / PROJECT REVIEW
Evaluate Tongzhou around documented assembly and refrigerant-circuit scope
Verify the manufacturing and contact locations before a visit
Ask which fabrication, assembly and testing processes take place at each address and where the selected order would be built. The registered address and current contact address have different roles; neither is replaced by the other in this assessment. Obtain visit arrangements and actual workshop equipment/process evidence.
The official licence lists refrigeration/air-conditioning manufacturing, but registration scope is not proof of pressure-vessel production approval. Determine which vessels, compressors and controls are bought in and which fabrication operations Tongzhou performs. Request applicable current documents for the actual ordered equipment.
Start with a complete selected circuit
For its pump package, issue required evaporating conditions, refrigerant, connected evaporators, line lengths and loads. Obtain the vessel/pump/control P&ID, component list, flow/head selection and protective logic. The actual source describes multiple oil-return points and heat-gas defrost capability; neither establishes an issued site sequence.
For screw or parallel units, require compressor makes/models, refrigerant circuit count and selected rating. The inspected evaporative and three-parallel pages give names/images but no enough technical schedule to identify a complete ordered assembly. They are research leads, not verified specifications.
Request testing and conformity within the order boundary
Obtain material/pressure documents, bought-in component records, welding/leak/pressure tests where applicable and the electrical/control acceptance plan. The pump page's electrical-brand statement is a supplier claim; verify actual parts and protection rather than treating a brand as complete-system safety approval.
No government award or recognition is adopted from unrelated search results. The independent platform page inspected confirms the company name but does not establish workshop capacity or technical certification. Use current exact-scope issuer records if certification is required by the project.
Separate shipment photographs from installed results
The official website shows shipment and site labels without an issued thermal test, customer acceptance or reliable selected equipment schedule. Request a relevant reference with permission to check the actual duty, installation and service experience. A photo of shipping does not establish operating performance.
Ask for lead time, spare-pump/control arrangements and the response to a plant fault. The reviewed contact page publishes phone/address but no official email; no email is guessed. Current quotation and independently verified production throughput remain unknown.
Confirm the build site
Match legal identity and address roles to actual fabrication/assembly processes.
Issue selected circuit duty
Obtain P&ID, bought-in components, pump/compressor selection and controls.
Agree acceptance
Freeze conformity, tests, site interfaces and traceable service/reference evidence.
