Tongzhou Weipu K6sv Compact Circulating Chiller

Overview

The Tongzhou Weipu K6sv Compact Circulating Chiller is an integrated, air-cooled refrigeration system engineered for stable, continuous thermal management in demanding laboratory and industrial environments. Utilizing a vapor-compression refrigeration cycle with R410A or equivalent environmentally compliant refrigerant, the unit delivers precise temperature control across a wide operational range (5–35 °C) while maintaining high thermal reproducibility (±0.2 °C stability under steady-state conditions). Its compact footprint and self-contained design eliminate the need for external cooling towers or chilled water infrastructure—making it ideal for installation in confined lab spaces, cleanrooms, or near sensitive instrumentation where noise, vibration, and spatial constraints are critical considerations. The chiller is designed to operate continuously under variable thermal loads, supporting applications requiring sustained heat extraction from exothermic processes or active cooling of optical, electronic, or mechanical components.

Key Features

• Integrated air-cooled architecture with high-efficiency scroll or rotary compressor, optimized for low ambient noise (<65 dB(A) at 1 m) and extended service life.
• Precision PID temperature control algorithm with digital setpoint interface and real-time display of bath temperature, outlet temperature, and system status.
• Stainless steel reservoir (50 L capacity) with level sensor, overflow protection, and corrosion-resistant internal wetted parts compatible with deionized water, glycol-water mixtures (up to 30% v/v), and other non-aggressive coolants.
• High-head circulating pump (3.6 bar max pressure, 60 L/min flow rate at zero backpressure) equipped with adjustable flow control valve and dry-run protection.
• Robust thermal insulation and condenser airflow optimization ensure consistent performance across ambient temperatures up to 35 °C.
• Standard RS485 communication port supporting Modbus RTU protocol for integration into centralized facility monitoring systems or PLC-controlled process environments.

Sample Compatibility & Compliance

The K6sv chiller is compatible with a broad spectrum of heat-generating equipment commonly deployed in analytical, materials science, and manufacturing laboratories—including rotary evaporators (up to 50 L scale), CO₂ lasers (≤500 W output), induction heating units, vacuum metallization chambers, tensile testing frames, and semiconductor process tools. It meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not certified to UL/CSA standards out-of-the-box, its electrical architecture complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) specifications. For GLP/GMP-regulated facilities, optional audit-trail-enabled firmware upgrades support 21 CFR Part 11-compliant electronic recordkeeping when paired with validated data acquisition software.

Software & Data Management

The K6sv operates via a front-panel touchscreen interface with intuitive menu navigation and password-protected configuration access. Optional PC-based software (Tongzhou Weipu ChillView™) enables remote monitoring, real-time trend logging, alarm history export (CSV format), and configurable setpoint scheduling. All temperature and operational parameters are timestamped and stored internally for ≥30 days. When connected to enterprise networks via optional Ethernet gateway module, the chiller supports SNMP v3 traps and MQTT publishing for interoperability with LabVantage, Thermo Fisher SampleManager, or custom SCADA platforms. Data integrity safeguards include cyclic redundancy checks (CRC) on all serial communications and write-protected firmware partitions.

Applications

• Thermal stabilization of laser cavities and diode arrays in spectroscopy and metrology setups.
• Cooling condenser jackets and vacuum pump heads in rotary evaporation systems to maximize solvent recovery efficiency.
• Heat removal from RF amplifiers, power supplies, and plasma generators in thin-film deposition and surface engineering tools.
• Temperature regulation of reaction media in jacketed bioreactors and fermentation vessels during kinetic studies.
• Active cooling of X-ray detectors, electron optics, and high-speed camera sensors to minimize thermal drift and dark current noise.
• Support of ASTM D5276 (impact testing) and ISO 6721 (dynamic mechanical analysis) protocols requiring controlled thermal environments for material characterization.

FAQ

What coolant types are compatible with the K6sv chiller?
Deionized water, 10–30% ethylene or propylene glycol/water mixtures, and approved synthetic heat-transfer fluids meeting ISO 6743-22 specifications. Avoid chlorinated solvents or oils.
Can the K6sv be used in a cleanroom environment?
Yes—its sealed refrigeration circuit, low particulate emission design, and optional HEPA-filtered intake kit meet ISO Class 5 (Class 100) cleanroom compatibility requirements when installed per manufacturer ventilation guidelines.
Is external temperature feedback supported?
Yes—via optional PT100 input terminal for external process temperature feedback loop integration, enabling cascade control configurations.
What maintenance intervals are recommended?
Compressor oil and refrigerant charge verification every 24 months; condenser coil cleaning every 6 months in dusty environments; pump impeller inspection annually.
Does the unit comply with environmental refrigerant regulations?
Yes—the system uses R410A (GWP = 2088) or R32 (GWP = 675) refrigerants, both compliant with EU F-Gas Regulation (EU) No 517/2014 phase-down schedules and EPA SNAP program approvals for laboratory chillers.
