Tongzhou Weipu TC6000 Series High-Low Temperature Circulating Chiller

Overview

The Tongzhou Weipu TC6000 Series High-Low Temperature Circulating Chiller is an engineered thermal management system designed for precision temperature control in demanding laboratory and pilot-scale industrial applications. Utilizing a dual-circuit refrigeration architecture combined with high-efficiency electric heating elements, the TC6000 achieves stable, repeatable thermal regulation across an exceptionally wide operational envelope—from −60 °C to +250 °C. This capability supports critical processes including exothermic/endothermic reaction control in pharmaceutical synthesis, thermal cycling of polymer composites, semiconductor device testing under extreme thermal stress, and low-temperature condensation in analytical sample preparation. The unit operates on a closed-loop principle, circulating thermally stable synthetic heat-transfer fluids through external process jackets, reactors, or instrumentation—ensuring minimal thermal lag and high spatial uniformity. Its robust mechanical design integrates industrial-grade compressors, corrosion-resistant fluid pathways, and redundant safety monitoring (including high/low pressure cut-offs, over-temperature protection, and flow fault detection), conforming to IEC 61000-6-2/6-4 electromagnetic compatibility requirements.

Key Features

• Wide temperature span: −60 °C to +250 °C, enabling both cryogenic process support and high-temperature material conditioning
• Modular cooling architecture: Selectable air-cooled (F) or water-cooled (W) configurations to match facility infrastructure and ambient constraints
• Intelligent multi-dimensional PID control algorithm with adaptive tuning, minimizing overshoot and stabilizing setpoints within ±0.3 °C under dynamic load conditions
• 7-inch industrial-grade TFT touchscreen interface with intuitive navigation, real-time trend display, and multilingual UI support (English, German, French, Chinese)
• Comprehensive programmability: Up to 100-step temperature ramps and holds, with independent slope rate control and event-triggered actions
• Standard industrial communication: Native Modbus TCP over Ethernet and RS485 Modbus RTU for seamless integration into SCADA, DCS, or LIMS environments
• Flexible I/O architecture: Isolated dry-contact outputs for alarm/status signaling, analog/digital inputs for external sensor feedback or master-setpoint override
• Explosion-proof variants available per ATEX Directive 2014/34/EU Category 2G (gas) and IECEx certification upon request

Sample Compatibility & Compliance

The TC6000 series is compatible with a broad spectrum of externally mounted equipment requiring precise thermal coupling—including glass-jacketed reactors (1–50 L), calorimeters, spectroscopic cells, environmental test chambers, and wafer-level thermal probes. It supports only non-reactive, thermally stable heat-transfer media; recommended fluids include AUSI-05 (−80 °C to 220 °C) and AUSI-10 (−60 °C to 250 °C), both certified to ISO 6743-12 classification HT-B and compliant with REACH Annex XIV SVHC screening. All wetted components are constructed from 316L stainless steel or fluoropolymer-lined surfaces to ensure chemical inertness against common solvents (e.g., THF, DMF, ethylene glycol/water mixtures). The system meets CE marking requirements under Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. For regulated environments, optional audit-trail logging and user-access control modules align with FDA 21 CFR Part 11 data integrity principles when paired with validated software configuration.

Software & Data Management

The embedded controller firmware supports local data logging at user-defined intervals (1 s to 60 min) with timestamped storage on internal flash memory or external USB drives (FAT32 formatted). Logged parameters include setpoint, actual bath temperature, compressor discharge/suction pressures, heater output %, pump flow rate, and alarm history. Export formats include CSV and PDF reports, compatible with Microsoft Excel and LabArchives ELN platforms. Remote monitoring and parameter adjustment are enabled via standard web browser access (HTTPS) or dedicated Windows client application. Optional OPC UA server module provides real-time tag publishing for enterprise MES integration. All configuration changes and operator logins are recorded with immutable timestamps and user IDs, satisfying GLP/GMP traceability requirements for quality-controlled laboratories.

Applications

• Pharmaceutical development: Controlled crystallization, hydrogenation, and lyophilization cycle validation
• Materials science: Thermal aging studies of aerospace composites, coefficient-of-thermal-expansion (CTE) measurement, and phase transition analysis
• Semiconductor R&D: Wafer-level thermal shock testing, die attach curing, and laser diode thermal stabilization
• Chemical engineering: Kinetic profiling of catalytic reactions, distillation column reflux control, and calorimetric enthalpy determination
• Biotechnology: Cryopreservation system pre-cooling, cold trap operation for vacuum manifolds, and bioreactor jacket temperature synchronization
• Automotive testing: Battery cell thermal cycling per ISO 12405-4 and UNECE R100 compliance protocols

FAQ

What heat-transfer fluids are compatible with the TC6000 series?
AUSI-05 and AUSI-10 synthetic oils are factory-recommended; alternatives must be verified for thermal stability, viscosity index, and compatibility with 316L stainless steel and FKM elastomers.
Can the TC6000 operate continuously at −60 °C?
Yes—units equipped with cascade refrigeration (standard on models ≥ TC6075H25) maintain continuous operation at −60 °C with appropriate fluid charge and ambient cooling conditions.
Is remote software update supported?
Firmware updates require authenticated USB media; over-the-air updates are disabled by default for security and regulatory compliance.
Does the system support external temperature feedback control?
Yes—via configurable PT100 input channel, enabling process-jacket or sample-core temperature as primary control variable instead of bath temperature.
What certifications are included with standard delivery?
CE, RoHS, and manufacturer’s Declaration of Conformity per applicable EU directives; additional certifications (UL, UKCA, ATEX) available upon request with lead-time extension.
