What this manufacturer offers
Zhejiang Sino King Refrigeration publishes a broad HVAC and refrigeration portfolio from its Dongyang company website. Its stated activities include equipment design, research, production, sales and service, with customized and differentiated products central to its declared strategy. This profile focuses on the evidence useful when buying its water-cooled screw low-temperature refrigeration family.
The company describes two branches and more than a thousand staff, but those are company-wide statements without a current headcount or order-specific production allocation in the reviewed material. They do not establish the capacity available for the requested delivery date.
The external records reviewed here support a named company and a separate SKZK evaporatively cooled product listing. Neither is a factory audit or a performance approval for the low-temperature screw unit. The first procurement task is to identify the contracting entity, manufacturing site and precise cooling duty in the same offer.

03 / PROJECT REVIEW
Review the supplier behind a low-temperature process-cooling offer
Three dates describe different kinds of history
The company overview separates a brand-origin date from formation and renaming. The detailed timeline is more specific about the businesses named at each stage. Preserve those distinctions when checking an old drawing, certificate or quotation.
1966: brand origin claim
The overview labels 1966 as brand creation. It does not say that the present Chinese legal entity was registered in 1966.
The timeline says Zhejiang Huilong Air Conditioning Equipment was established in 2005 and Zhejiang Sike Guoxiang Refrigeration Equipment in 2010. No registry documents establishing each transfer or legal succession were reviewed.
The company records a change to 浙江思科制冷股份有限公司 on 6 February 2017. For an order, match the current entity on the contract, invoice and applicable certificates.
Keep process refrigeration separate from comfort cooling
The reviewed low-temperature publication describes a screw unit supplying a medium- or low-temperature secondary coolant, with a cooling tower or another cooling-water source required. It names ethylene-glycol and calcium-chloride solutions as alternatives. This is a different selection task from an ordinary comfort-cooling water schedule.
The broader catalogue also groups water-cooled equipment/heat pumps, air-cooled equipment/heat pumps, terminal products, commercial units, refrigeration and integrated systems. These divisions show the published offer; they are not proof that a given selection is suitable for every pharmaceutical, agricultural or industrial process.
Ask which team will select the low-temperature unit and who is responsible for the secondary-fluid circuit and heat-rejection equipment. The separate product review below sets out the missing duty and integration data. No outlet-temperature range, refrigerant, cooling capacity or food/pharmaceutical compliance has been inferred.
Water-cooled low-temperature screw family
Review against coolant chemistry, temperature and process duty. The public family text has no exact model-by-model rating table.
A separate external listing names this different family. Its standard and published service terms cannot be transferred to the low-temperature screw unit.
Factory expansion and laboratory claims need an order-specific check
The company history records initial production stages in 2011–2012, five laboratories in 2019, a third-phase plant construction start in 2025 and a CNAS laboratory-recognition claim in 2026. These are statements on the company’s timeline. No accreditation number, scope schedule, expiry record or low-temperature test capability was established from the readable history.
The factory-gallery page publishes facility photographs without usable captions identifying each line, date, throughput or inspection activity. A photograph and an expansion announcement do not establish the current status of a particular line.
Request the manufacturing address, proposed assembly/test location, applicable laboratory scope and the selected unit’s inspection plan. If the offer relies on an accredited test, match the actual test method, range, laboratory and report to that claim. No current annual output or factory-completion date has been added.
External records: useful identity evidence with limited scope
The Zhejiang securities regulator published a notice naming this company on 2 September 2021 under IPO counselling filings. This confirms the named historical filing; it does not establish a present stock-market listing, an approved offering or equipment certification.
The Zhejiang Made platform separately lists SKZK evaporatively cooled screw equipment at Guangfu East Street 1233 and cites T/ZZB 0406—2018. Its company biography repeats supplier statements. The listing is not evidence that every Sino King family has the same certification or verified performance.
Use these records to cross-check the entity and distinguish product families. Request current, identifiable certificates and their exact scope for the ordered equipment rather than relying on corporate awards or a generic three-systems-certification statement.
Write service responsibilities around the actual process
The official company overview describes nationwide sales offices and internet-assisted service, without publishing a destination-specific service agreement for the low-temperature family. A network description does not establish who will attend an overseas site or how quickly the required part will arrive.
Agree selection responsibility, supply boundaries, commissioning, operator training, spare parts and local support before placing the order. The following outline is an editorial purchasing workflow, not a service commitment made by the manufacturer.
Name the supplying and attending parties
Match the contract entity and factory, and identify the organisation responsible for startup and fault attendance at the project location.
Separate equipment from system work
List the chiller, secondary-fluid circuit, cooling-water/tower system, controls, wiring, installation and commissioning responsibilities. Mark exclusions explicitly.
Agree a handover package
Obtain the selected model/duty sheet, manuals, drawings, alarm/protection documentation, acceptance records and written warranty/support terms for this specific family.
