Overview
The Titan HLT-2020 is an integrated high-low temperature circulating chiller engineered for precision thermal control in demanding laboratory and industrial applications. Utilizing a dual-mode refrigeration-heating system based on vapor-compression thermodynamics with PID-controlled electric heating elements, the unit maintains stable bath temperatures across a wide operational span—from cryogenic −20 °C to elevated +100 °C—without requiring external heat exchangers or auxiliary fluid conditioning. Its robust architecture supports continuous-duty operation, making it suitable for integration with analytical instruments such as spectrophotometers, calorimeters, rotary evaporators, and laser systems where thermal drift must be minimized over extended experimental cycles.
Key Features
- Integrated design eliminates need for separate chillers and heaters—reduces footprint, interconnection complexity, and potential failure points.
- High-precision temperature regulation with ±0.05 °C stability at setpoint, achieved via multi-sensor feedback loop and adaptive PID algorithm optimized for dynamic load conditions.
- Water-cooled condenser ensures consistent refrigeration performance independent of ambient air temperature fluctuations—ideal for enclosed labs or high-heat environments.
- High-flow circulation pump delivers 33.3 L/min at 0.7 bar discharge pressure, supporting large-volume external loops or multiple instrument connections with minimal pressure drop.
- 20-liter stainless-steel reservoir with level sensor, overflow protection, and corrosion-resistant internal coating compatible with water, water-glycol mixtures, and low-conductivity heat transfer fluids.
- Continuous-duty rated compressor and reinforced motor windings enable uninterrupted operation for >8,000 hours per year under nominal load conditions.
Sample Compatibility & Compliance
The HLT-2020 is designed for closed-loop thermal management of external equipment—not for direct sample immersion. It 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). Its fluid-handling components are constructed from 316 stainless steel and EPDM-sealed fittings, ensuring compatibility with ASTM D1384-corrosion-tested coolants and USP-grade glycol solutions. While not inherently 21 CFR Part 11 compliant, its analog/digital I/O interface supports integration into validated systems when paired with third-party audit-trail-capable controllers meeting GLP/GMP documentation standards.
Software & Data Management
The unit features a front-panel touchscreen interface with real-time graphing of temperature, flow rate, and system status. Optional RS485 Modbus RTU and Ethernet (TCP/IP) interfaces enable remote monitoring and control via LabVIEW, MATLAB, or SCADA platforms. Logged data—including timestamped temperature traces, alarm history, and pump runtime—is exportable as CSV files for traceability. Firmware supports user-defined setpoint profiles with up to 10 ramp-hold segments, facilitating automated thermal cycling protocols required in material testing (e.g., ISO 6721-1, ASTM E1356) and pharmaceutical stability studies.
Applications
- Temperature stabilization of UV-Vis and FTIR spectrometers during long-duration spectral acquisition.
- Cooling of high-power lasers and optical benches requiring sub-0.1 °C thermal homogeneity.
- Thermal conditioning of reaction vessels in process development labs operating under cGMP-aligned workflows.
- Supporting differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) systems requiring precise bath temperature tracking.
- Environmental simulation for electronics reliability testing per JEDEC JESD22-A104 and MIL-STD-810G methods.
FAQ
What fluids are compatible with the HLT-2020 reservoir and circulation system?
Deionized water, 20–50% propylene glycol/water mixtures, and low-conductivity silicone oils (up to 100 cSt viscosity) are supported. Ethylene glycol is not recommended due to accelerated elastomer degradation.
Can the unit operate unattended for 72+ hours?
Yes—provided fluid level, ambient cooling water supply (for water-cooled condenser), and external loop integrity are verified prior to initiation. Built-in dry-run and overtemperature safeties trigger automatic shutdown.
Is external calibration certification available?
Titan provides factory calibration reports traceable to NIM (National Institute of Metrology, China). Third-party ISO/IEC 17025 calibration services can be arranged through authorized regional partners.
Does the HLT-2020 support programmable ramp-and-soak temperature profiles?
Yes—via optional software interface or onboard touchscreen. Up to 10 segments with independent ramp rates (0.1–10 °C/min) and hold durations (1 min–99 h 59 min) are configurable.
What maintenance intervals are recommended for continuous operation?
Condenser cleaning every 3 months (if using municipal water), refrigerant pressure verification annually, and pump impeller inspection every 2 years under typical lab usage (8 h/day, 5 days/week).
