Overview
The Titan HLC-0820E is an integrated high-low temperature circulating chiller engineered for precision thermal control in laboratory and analytical instrumentation applications. It employs a dual-mode refrigeration-heating system based on a hermetically sealed compressor and PID-controlled electric heating elements, enabling stable, programmable temperature maintenance across a broad operational range of −20 °C to +100 °C. Unlike modular or external-coil systems, the HLC-0820E integrates the refrigeration circuit, expansion tank, circulation pump, and controller into a single compact chassis—reducing footprint, minimizing fluid path complexity, and enhancing thermal response consistency. Its design targets applications requiring high reproducibility in temperature-dependent processes, including spectrophotometer cell cooling, rotary evaporator condenser management, calorimetry reference baths, and material testing environmental chambers.
Key Features
- Integrated architecture with self-contained refrigeration, heating, pumping, and digital control—no external chillers or auxiliary heaters required
- PID-regulated temperature control delivering ±0.05 °C stability over full operating range, verified per ASTM E742-22 calibration protocol
- High-flow circulation system with 22 L/min nominal flow rate and dual-pressure specification (0.3 bar discharge / 0.2 bar suction), suitable for low-impedance and moderate-head external loops
- 8-liter stainless-steel reservoir with level sensor, overflow protection, and corrosion-resistant internal wetted surfaces compatible with water, water-glycol mixtures, and low-conductivity heat transfer fluids
- Water-cooled condenser design optimized for ambient environments ≤35 °C; includes pressure-sensing interlock to prevent compressor operation under insufficient coolant flow
- Continuous-duty rated motor and refrigeration cycle—validated for 24/7 operation under load without thermal derating
Sample Compatibility & Compliance
The HLC-0820E supports closed-loop circulation with external equipment having inlet/outlet ports conforming to standard 1/4″–3/8″ NPT or G1/4″ BSP fittings. Its fluid compatibility covers deionized water, 30–50% aqueous ethylene glycol solutions, and non-halogenated synthetic heat transfer oils (viscosity ≤50 cSt at 25 °C). The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU). Internal logging and setpoint history support GLP-compliant audit trails when connected to Titan’s optional RS485-to-Ethernet gateway (firmware v2.3+).
Software & Data Management
The onboard 4.3″ TFT touchscreen interface provides real-time monitoring of bath temperature, outlet temperature, flow status, compressor runtime, and fault codes. All parameters—including ramp rates, hold times, and multi-step profiles—are configurable via intuitive menu navigation. Optional TitanLink™ PC software (Windows/macOS) enables remote setpoint adjustment, data export in CSV format, and synchronized timestamped logging at user-selectable intervals (1 s to 10 min). When deployed in regulated environments, firmware supports FDA 21 CFR Part 11–compliant user authentication (role-based access), electronic signatures, and immutable event logs—fully traceable to individual operator ID and session timestamp.
Applications
- Temperature stabilization of UV-Vis, FTIR, and fluorescence spectrometer sample compartments and detectors
- Cooling of rotary evaporator condensers during solvent recovery at elevated bath temperatures (e.g., 60–80 °C)
- Thermal conditioning of rheometer measuring systems, DSC pans, and TMA fixtures
- Environmental simulation for polymer tensile testing, battery cycling chambers, and semiconductor probe stations
- Calibration of thermocouples, RTDs, and infrared thermometers using NIST-traceable reference baths
FAQ
What is the maximum allowable backpressure for external systems connected to the HLC-0820E?
The unit is rated for continuous operation with up to 0.8 bar static backpressure at the outlet port; exceeding this may reduce flow rate and impair temperature stability.
Can the chiller operate unattended overnight with a programmed temperature profile?
Yes—the internal scheduler supports up to 10 segmented profiles with independent start/stop times, and power-loss recovery resumes the last active program upon reboot.
Is the reservoir volume sufficient for integration with a 3-meter external loop containing ~5 L of fluid?
With an 8 L bath and 5 L external volume, total system fill is 13 L; the unit’s expansion capacity accommodates ±8% thermal volume change, making it suitable for such configurations.
Does the chiller support external PT100 input for cascade control?
No—control is bath-referenced only; however, analog 0–10 V or 4–20 mA output signals (optional module) can relay bath temperature to external PLCs or DAQ systems.
What maintenance intervals are recommended for long-term reliability?
Compressor oil and refrigerant charge require no scheduled service within first 36 months; annual inspection of pump seals, coolant pH (if using water-based fluids), and condenser coil cleanliness is advised per ISO 5171 maintenance guidelines.
