Overview
The Titan HLC-0520S is an integrated high-low temperature circulating bath engineered for precise thermal control in laboratory and pilot-scale applications. Utilizing a dual-mode thermoelectric-compressor hybrid system with independent heating and cooling circuits, it maintains stable setpoint temperatures across a wide operational range—from cryogenic −20 °C to high-temperature 200 °C—without requiring external heat exchangers or auxiliary chillers. Its closed-loop circulation architecture delivers consistent thermal transfer to external devices such as spectrophotometer cells, reaction jackets, calorimeters, and material testing fixtures. Designed for continuous-duty operation under GLP-compliant environments, the HLC-0520S meets the thermal stability demands of analytical method validation, polymer processing studies, and pharmaceutical stability testing per ICH Q1 guidelines.
Key Features
- High-precision temperature regulation with ±0.03 °C stability over full range, verified via NIST-traceable Pt100 sensor and PID-controlled feedback loop
- Integrated water-cooled refrigeration system with low-GWP R-449A refrigerant, minimizing environmental impact while delivering 400 W nominal cooling capacity at 20 °C ambient
- 2000 W resistive heating module enabling rapid ramp rates up to 8 °C/min (typical, load-dependent), supporting dynamic thermal profiling protocols
- Dual-head magnetic drive circulation pump rated for 22 L/min flow at 0.3 bar discharge pressure and 0.2 bar suction lift—compatible with tubing up to 10 m total length and 15 m head loss
- 5-liter stainless steel reservoir with level sensor, leak detection circuitry, and overflow protection; compatible with water, water/glycol mixtures (up to 50% v/v), and low-viscosity silicone oils
- Front-panel 7-inch capacitive touchscreen interface with real-time graphing, programmable ramp/soak cycles, and password-protected parameter locking for audit-ready operation
Sample Compatibility & Compliance
The HLC-0520S supports seamless integration with a broad spectrum of external equipment—including UV-Vis spectrophotometers, FTIR accessories, rheometers, differential scanning calorimeters (DSC), and environmental test chambers—via standardized 1/4″–1/2″ quick-connect fluid ports. Its fluid path components are constructed from 316 stainless steel, PTFE-lined solenoid valves, and EPDM-free wetted materials to ensure chemical compatibility and prevent leachables. The unit complies with IEC 61010-1:2010 for electrical safety, CE marking requirements, and RoHS 2015/863/EU directives. Optional firmware upgrade enables 21 CFR Part 11-compliant electronic signatures, audit trail logging, and user role-based access control—fully aligned with FDA-regulated QC laboratories operating under GMP/GLP frameworks.
Software & Data Management
Titan’s proprietary ThermLink™ software (v3.2+) provides remote monitoring and control via Ethernet or USB-C connection. It supports real-time data streaming at 1 Hz resolution, customizable alarm thresholds (e.g., low-flow, overtemperature, reservoir depletion), and export of timestamped CSV datasets for statistical process analysis. All configuration changes, setpoint adjustments, and alarm events are recorded in an immutable audit log with ISO 8601 timestamps and operator ID tags—meeting ALCOA+ data integrity principles. Batch reports can be auto-generated with embedded calibration certificates, instrument identification, and environmental metadata for regulatory submissions.
Applications
- Temperature-controlled kinetic studies in enzymatic and catalytic reactions
- Calibration of temperature-sensitive transducers and reference standards
- Thermal cycling of optical components during laser system alignment
- Stability testing of APIs and formulations per ICH Q5C and USP <1151>
- Cooling of high-power LED arrays and semiconductor test fixtures
- Preconditioning of composite specimens prior to tensile or DMA analysis
FAQ
What fluids are compatible with the HLC-0520S reservoir system?
Deionized water, 20–50% aqueous glycol solutions (propylene or ethylene), and low-volatility silicone oils (e.g., Dow Corning 200 Fluid, viscosity ≤50 cSt) are validated for use. Avoid halogenated solvents, strong oxidizers, or fluids with vapor pressure >10 kPa at 25 °C.
Can the unit operate unattended for extended periods?
Yes—designed for 7×24 continuous operation with redundant thermal cutoffs, dry-run protection, and automatic fault recovery. Recommended preventive maintenance interval is every 12 months or 2000 operating hours.
Is external chiller water required for the water-cooled condenser?
Yes; a facility-supplied cooling water source at 10–30 °C and ≥2 bar pressure is mandatory for optimal refrigeration performance. A flow switch interlock prevents compressor activation if water flow falls below 1.5 L/min.
How is temperature uniformity verified across the circulation loop?
Uniformity is characterized per ASTM E220–22 using calibrated probe arrays at inlet/outlet and mid-loop positions. Typical deviation remains ≤±0.05 °C under steady-state conditions with 15 m of 1/4″ SS tubing and 2 L/min external flow resistance.
Does the system support third-party SCADA integration?
Yes—Modbus TCP/IP (port 502) and OPC UA (IEC 62541) communication protocols are embedded and configurable via the ThermLink™ software suite, enabling direct linkage to LabVantage, DeltaV, or custom MES platforms.
