Xiatech C2100 High-Temperature Circulating Oil Bath

Overview

The Xiatech C2100 High-Temperature Circulating Oil Bath is a precision temperature control system engineered for laboratory and industrial applications requiring stable thermal environments up to 200 °C. Unlike conventional water baths, the C2100 is optimized for use with silicone oil and other high-boiling-point heat transfer media, enabling continuous operation across an extended temperature range without media replacement. Its design follows fundamental principles of convective thermal equilibrium and closed-loop PID temperature regulation, ensuring minimal thermal drift and high spatial uniformity within the bath chamber. The unit integrates a high-efficiency heating element, dual-sensor feedback architecture, and a robust circulation pump to maintain consistent temperature distribution—critical for calibration laboratories, material property testing (e.g., viscosity, thermal expansion), and sensor validation procedures compliant with ISO/IEC 17025 requirements.

Key Features

• Extended operating range from ambient +10 °C to 200 °C, validated for long-term stability under continuous load
• High-precision temperature control with ±0.05 °C stability and 0.001 °C resolution, traceable to NIST-certified reference standards
• Dual-mode circulation system supporting both internal recirculation and external loop integration via standard 1/2″ BSP fittings
• Integrated safety interlocks including over-temperature cutoff and low-fluid-level detection to prevent dry-run damage
• USB 2.0 interface enabling real-time data logging, remote setpoint adjustment, and script-based automation via third-party software (e.g., LabVIEW, Python)
• Stainless steel bath tank with corrosion-resistant finish and optimized geometry for uniform thermal conduction and minimal edge effects

Sample Compatibility & Compliance

The C2100 accommodates a wide range of sample configurations—including immersion probes, calorimeter cells, viscometer spindles, and optical test fixtures—within its 10 L bath volume and 100×180 mm opening. Its depth of 200 mm ensures full submersion of standard ASTM E2251-compliant thermometers and reference sensors. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets electromagnetic compatibility (EMC) requirements per EN 61326-1. When operated with certified calibration oils (e.g., Paratherm NF, Dow Corning 200 Fluid), it supports temperature calibration workflows aligned with ISO 17025 Clause 6.5.2 and supports audit-ready documentation when paired with validated temperature control software.

Software & Data Management

The C2100 communicates via a standard USB virtual COM port, exposing raw sensor readings, setpoint history, and pump status registers through a documented ASCII protocol. Users may implement custom data acquisition using open-source libraries (e.g., PySerial) or integrate with commercial platforms such as MATLAB Instrument Control Toolbox or Keysight PathWave. Optional firmware updates provide enhanced logging intervals (100 ms to 60 s), CSV export capability, and timestamped event flags for GLP/GMP-aligned recordkeeping. While the device does not natively support FDA 21 CFR Part 11 electronic signatures, its deterministic communication behavior enables integration into validated systems where audit trails and user access controls are managed at the host application layer.

Applications

• Calibration of RTDs, thermistors, and liquid-in-glass thermometers per ASTM E77 and ISO 5725
• Thermal preconditioning of polymer samples prior to DSC or TMA analysis
• Stabilization of optical components during interferometric measurement campaigns
• Controlled-temperature aging studies for electronic components per JEDEC JESD22-A108
• Reference environment for validating high-temperature pressure transducers and flow meters
• Supporting ASTM D445 kinematic viscosity measurements using calibrated capillary viscometers

FAQ

What temperature media are compatible with the C2100?

Silicone oils (e.g., Dow Corning 200 Fluid series), polyalkylene glycols, and synthetic heat transfer fluids with flash points above 220 °C are recommended. Water is not suitable due to boiling and oxidation risks above 100 °C.
Does the C2100 support external temperature feedback control?

No—the system operates in internal sensor feedback mode only. External probe input is not supported; however, users may log external sensor data synchronously via USB and perform post-hoc correlation analysis.
Is the bath tank removable for cleaning or maintenance?

The stainless steel tank is permanently mounted but accessible via front-panel service covers. Cleaning is performed in situ using low-residue solvents compatible with 316 stainless steel.
Can multiple C2100 units be synchronized for multi-zone thermal control?

Synchronization is not hardware-supported, but time-aligned operation can be achieved via host PC coordination using the USB interface and shared NTP time sources.
What is the maximum allowable external loop pressure drop?

The integrated pump delivers 16 L/min at ≤0.2 bar backpressure. For external loops exceeding 1.5 m total equivalent length, auxiliary pumping is recommended to maintain flow stability.
