ReeWui Automation Technology (Shanghai) Co., Ltd. develops industrial temperature-control products and application solutions. Its published range connects temperature sensors, panel and DIN-rail controllers, power-control devices and automation interfaces, with an emphasis on heating processes and equipment integration.
What the published manufacturing scope means for a buyer.
The English website links to a Chinese company site identifying 利汇自动化科技（上海）有限公司. That site separates its Minhang office from a stated Songjiang factory address. For procurement, ReeWui is best evaluated as an instrument and thermal-control supplier: furnaces, plastics machinery and other equipment shown in its application sections are use cases, not evidence that it manufactures those complete machines. The useful comparison is how its proposed sensor, controller, power stage and communication configuration fit one defined heating process. [2]
The catalogue covers temperature sensing, control instruments and power-control devices. This provides a starting point for specifying a coordinated loop rather than buying each component without checking its electrical and signal interfaces. [1]
The SE-TC page organizes thermocouple selection around element type, process connection, sheath, lead insulation and junction configuration, with probe dimensions and calibration requirements specified separately. Those choices are useful inputs to a project-specific quotation. [5]
A company case note describes replacing contactor-based annealing-furnace controls with temperature controllers, SCR power regulation and recording. It illustrates the company's proposed integration scope; measured savings and a guaranteed retrofit result are not established by this profile. [9]
CNFX synthesis of the company’s published information.
Keep sensing, decision-making and power switching separate in the specification, then agree their interfaces as a system.
The published range includes thermocouples, RTDs, infrared sensing and temperature transmitters. Selection should identify the measurement location, medium, sensor construction and output required by the receiving instrument. Category-wide temperature or accuracy figures should not replace a selected part's controlled datasheet. [4]
Panel-mounted and DIN-rail products address local control and distributed instrumentation. Define sensor inputs, control outputs, alarm functions and the exact ordered configuration. Channel counts and communications must be confirmed for that configuration rather than inferred from the broad series description. [6]
The PC-SC1 listing describes a single-phase SCR power-controller offering. Start an enquiry with the heater or load type, supply, required current, control signal and cabinet conditions. Include cooling, protection and commissioning responsibilities in the scope instead of treating the power controller as a complete electrical safety system. [7]
Published processes, organized by production stage.
Identify zones, measurement points, target operating conditions, existing cabinet interfaces and the control behaviour required. The company's published service scope includes application-oriented configuration and support. [2]
Align sensor input, controller output, power-stage command and plant communication. Use exact model and firmware documentation, an I/O schedule and wiring drawings before committing to a replacement or integrated system. [6]
For a retrofit, define the baseline, operating conditions, recording method, alarm/interlock checks and handover files. The annealing example identifies control, power regulation and recording as linked work packages; it does not substitute for project acceptance testing. [9]
Acceptance should be tied to the selected instrument and operating conditions, with the complete loop assessed separately from an individual controller.
Request the selected probe or instrument's calibration record, range, uncertainty and traceability information. The thermocouple page offers calibration options; the requested document and its issuer should be part of the order rather than assumed from a general website label. [5]
Obtain the manual and register map for the actual model and firmware. Confirm addressing, data types, scaling, write permissions and error handling during integration. A protocol file for another controller family is not sufficient to establish compatibility. [8]
Agree temperature stability, process quality and energy-measurement criteria before comparing a retrofit with the existing installation. Load, production throughput and test period must remain part of that comparison. [9]
Company material describes thermal-process applications and one annealing-furnace retrofit note.
The case note combines temperature control, SCR power regulation, recording and plant communication in an annealing-furnace upgrade. Its value here is the integration approach. The case does not identify a customer or provide original measurement logs, so numerical improvement claims are not reproduced. [9]
The company's temperature-instrument and sensor portfolio may be relevant to builders specifying heating zones or replacing instruments. Confirm electrical fit, mechanical mounting, required documentation and support for the exact installed configuration. [2]
CNFX procurement assessment.
ReeWui may suit enquiries that combine temperature measurement, control instruments and a defined power-control or integration requirement. A productive first discussion includes the current loop diagram and the intended process behaviour. Its published portfolio is broader than the models reviewed here; proposals should identify the exact supplied items, their manufacturing or sourcing scope, and the party responsible for commissioning.
