Overview
The Titan HLT-1720 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 resistance heating, the unit maintains stable setpoint temperatures across a wide operational range—from cryogenic −20 °C to elevated +100 °C—without requiring external heat exchangers or auxiliary chillers. Its water-cooled condenser design ensures consistent performance under ambient conditions up to 35 °C, making it suitable for installation in equipment rooms or near heat-sensitive instrumentation where air-cooled units may experience capacity derating. The system’s continuous-duty architecture supports unattended 24/7 operation, meeting requirements for long-duration experiments such as polymer curing, reaction calorimetry, and spectrometer temperature stabilization.
Key Features
- Wide temperature span: −20 °C to +100 °C with ±0.05 °C stability at setpoint—validated per ISO 17025 traceable calibration protocols
- Integrated dual-function thermal management: 2400 W refrigeration output combined with 3000 W resistive heating capacity for rapid ramping and overshoot suppression
- High-flow positive-displacement circulation pump delivering 22 L/min at 1.0 bar pressure—optimized for low-pressure-drop external loops including jacketed reactors, viscometers, and laser cooling manifolds
- 17-liter stainless-steel reservoir with level sensor, anti-corrosion coating, and integrated air venting to prevent cavitation and vapor lock
- Water-cooled condenser with automatic flow interlock—compatible with standard municipal or closed-loop cooling water supplies (inlet: 10–30 °C, min. 1.5 L/min)
- Industrial-grade touchscreen HMI with real-time trend logging, alarm history, and configurable safety limits (high-temp, low-flow, low-level, overpressure)
Sample Compatibility & Compliance
The HLT-1720 is designed for closed-loop circulation of water-glycol mixtures (up to 35% v/v) or other non-corrosive heat transfer fluids compatible with 316 stainless steel, EPDM seals, and brass fittings. It complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emission) standards. Electrical safety meets IEC 61010-1 for Laboratory Equipment. While not certified for hazardous locations, its sealed refrigerant circuit (R-404A or R-507 option) and double-insulated pump housing support use in Class 1000 cleanrooms and GLP-compliant environments. Documentation includes Factory Acceptance Test (FAT) reports and material compliance declarations per RoHS 2015/863/EU and REACH SVHC.
Software & Data Management
The embedded controller supports Modbus RTU (RS-485) and optional Ethernet/IP communication for integration into LabVantage, DeltaV, or custom SCADA systems. Logged data—including temperature setpoint, actual bath temperature, flow rate, compressor status, and error codes—is stored internally for ≥30 days and exportable via USB or network share in CSV format. Audit trails meet FDA 21 CFR Part 11 requirements when used with validated third-party LIMS interfaces; electronic signatures, user access levels (admin/operator/guest), and immutable event logs are configurable. Firmware updates are performed offline via signed .bin files to ensure integrity.
Applications
- Temperature control of analytical instruments: HPLC column ovens, FTIR sample compartments, XRD goniometers, and SEM stage coolers
- Process simulation: Accelerated aging studies per ASTM D573 and ISO 188; thermal cycling of electronic assemblies
- Material testing: Dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC), and rheometer Peltier stage conditioning
- Biotechnology: Fermentor jacket cooling, PCR thermal cycler validation, and cold-room backup systems
- Chemical synthesis: Exothermic reaction quenching, crystallization profiling, and reflux condenser temperature regulation
FAQ
What is the minimum allowable coolant temperature for continuous operation?
The unit is rated for sustained operation at −20 °C using a 30% ethylene glycol/water mixture. Lower temperatures require specialized fluid formulations and are not covered under standard warranty.
Can the HLT-1720 be integrated into a building management system (BMS)?
Yes—Modbus RTU output enables direct connection to BACnet gateways or Siemens Desigo CC platforms via protocol translation; configuration files and register maps are provided in the technical manual.
Is remote monitoring supported without additional hardware?
The built-in web server allows secure HTTPS access for status viewing and basic parameter adjustment (no firmware update or log download); full functionality requires optional TitanLink software license.
Does the chiller meet ISO/IEC 17025 requirements for accredited laboratories?
While the instrument itself is not accredited, its documented metrological characteristics—including temperature uniformity mapping, stability verification, and calibration certificate traceability to NIM (China) or NIST (USA)—support compliance with ISO/IEC 17025:2017 clause 6.4.6 for equipment qualification.
What maintenance intervals are recommended for optimal service life?
Condenser water filter inspection every 3 months; refrigerant circuit leak check annually; glycol concentration and pH test semiannually; full system performance validation every 24 months per manufacturer’s PQ protocol.
