ZEL Tianjin · Hermetic refrigeration compressors

Separate the legal entity from the historical brand story

The official company narrative describes earlier refrigerator-compressor activities and an acquisition in 2013 by an aerospace precision-machinery business. The registered Tianjin company date in the source CRM is 1992. No transaction document or current group-ownership record was reviewed, so the platform does not infer present ownership or extend a predecessor’s age to this company.

The external HVACR.cn brand profile recognises the same manufacturer and 1992 formation, but also contains historical production figures and an older Hedong address. Those dated/undated figures are not used as current capacity or market share. Use the current official contact and preserved registration to identify the contracting party, then verify the actual order-production site.

Choose a compressor platform and appliance application

The overview positions Tau toward larger displacement/output, Lambda toward compact designs, Zeta toward aluminium-winding value and Micro toward very small assemblies. It also names TauVSC and ZetaVSC variable-speed families. These are supplier platform descriptions, not evidence that a given model meets an appliance’s pull-down, noise or efficiency target.

Identify the actual refrigerant, appliance duty and permitted operating envelope before asking for a price. The compressor is only one component: start equipment or drive, oil, mounting, piping and controls must match the actual selected configuration. No cold-room or complete refrigeration-system rating is assigned to a compressor catalogue entry.

Demand a model-specific rating file instead of accepting zero cells

The R134a and R600a pages publish model tables with motor/start codes, displacement entries, frequency and performance columns. Some frequency cells are zero; several power and COP fields also show zero. The table headers do not establish a complete thermal-test basis or units for every quantity. Those cells are not promoted as real zero-power or zero-frequency operation.

Require a current manufacturer datasheet with the exact model suffix, supply, refrigerant, test conditions, units and operating limits. A pair of catalogue output/input numbers cannot be compared across platforms without a common rating basis. Source anomalies should be resolved by the manufacturer, not silently filled by the platform.

The manufacturer-linked 32-page sample catalogue carries document code ZR0100.202004 and repeats the same legal name, Baoshui Road address and official email on its final page. It supplies unit-labelled ASHRAE LBP schedules, naming rules, outline/wiring and accessory drawings. Its rows differ from the web tables in several performance, winding and start-code entries. Treat it as a separately identified source version, not automatic proof of current stock or the ordered revision. Specific examples and conditions are documented on the platform product briefs.

Reconcile photographs, approvals and supply contents

The Tau R134a page shows a photographed HTH14AA unit labelled R600a. The variable-speed page photograph carries HDZ200FSM while its table lists HKD models. These are useful warnings against identifying an order from a family picture. Lambda’s R600a photograph does visibly identify HDL140A, while the Zeta photograph shows HXZ170A beyond the nine rows on the reviewed Zeta page.

Markings visible on one pictured compressor do not verify current approval of all platform variants. Request the exact model’s present documents and the supplied start/drive equipment. The official homepage’s general warranty/service claims need order-specific written terms; no platform-wide warranty or certification guarantee is made here.

The original honour-gallery images were individually inspected. One ISO 9001 image expressly names Gongyi City Xianke Water Supply Material Co., Ltd., not the Tianjin compressor company. Other certificates have obscured holders or unrelated subject matter. These images are excluded from ZEL credentials. Ask for legible current documents with the exact compressor-company holder, product and site scope before relying on any qualification claim.

Prepare an appliance-specific supplier enquiry

Issue the intended appliance, refrigerant, required performance conditions, ambient range, supply and starting/control constraints. Ask for the exact model/suffix, application approval and matched electrical equipment, together with outline and connection drawings. Obtain the actual sample/qualification and production acceptance arrangements appropriate to that order.

Confirm delivery contents, available production lead time, traceability and written service terms. Current prices, stock, factory throughput and independently witnessed appliance results remain unknown. The platform wrote this profile from reviewed sources, without a factory audit. The official website email is stored in a dedicated private CRM field; no outreach has been sent.

1. Define the appliance

   Specify refrigerant, duty conditions, power supply and control constraints.

2. Freeze the exact compressor

   Obtain current suffix-specific data, matched start/drive equipment and application documents.

3. Agree supply and validation

   Record sample/acceptance scope, contents, traceability, lead time and service terms.
