Overview
The Titan HLD-25 Integrated Dynamic Temperature Control System is an engineered solution for precise, bidirectional thermal regulation in laboratory and pilot-scale applications. Unlike conventional chillers or heating circulators operating unidirectionally, the HLD-25 integrates refrigeration and resistive heating within a single compact architecture—enabling seamless transition between sub-zero cooling and high-temperature heating without external switching or auxiliary units. Its core thermodynamic design employs a dual-circuit vapor-compression refrigeration system coupled with a high-efficiency immersion heater and PID-controlled power modulation. This allows stable setpoint maintenance across its full −30 °C to +200 °C operational envelope, making it suitable for demanding processes such as reaction calorimetry, material testing under thermal stress, and temperature-dependent spectroscopic measurements.
Key Features
- Integrated dual-mode thermal control: Simultaneous refrigeration (2500 W) and heating (3000 W) capability eliminates need for separate hot/cold units and reduces system footprint.
- Air-cooled condenser design: Eliminates dependency on facility cooling water; enables deployment in labs without chilled-water infrastructure.
- High-stability temperature regulation: Achieves ±0.3 °C stability at setpoint over extended continuous operation—validated per ISO 17025 traceable procedures using calibrated PT100 sensors.
- Robust circulation subsystem: Stainless-steel impeller pump delivers consistent 30 L/min flow against up to 1.5 bar backpressure, compatible with jacketed reactors, viscometers, and analytical instrument cooling manifolds.
- Compact reservoir design: 3 L insulated stainless-steel tank minimizes fluid volume while supporting rapid thermal response and reducing glycol consumption.
- Continuous-duty rated electronics and compressor: Designed for 24/7 operation under load; includes thermal overload protection, low-level fluid cutoff, and pressure fault monitoring.
Sample Compatibility & Compliance
The HLD-25 is compatible with standard heat-transfer fluids including water, 30–50% aqueous ethylene glycol, and silicone oil (up to 200 °C). Its fluid path is constructed from chemically resistant materials—316 stainless steel tubing, EPDM seals, and borosilicate glass sight gauges—to ensure long-term compatibility with mildly aggressive solvents and process streams. The unit complies with IEC 61000-6-3 (EMC emissions), IEC 61000-6-2 (immunity), and meets CE marking requirements for laboratory equipment. While not intrinsically rated for hazardous areas, optional ATEX-compliant variants are available upon request. All firmware and hardware configurations support audit-ready documentation for GLP and GMP environments—including timestamped temperature logs, user-access controls, and event-triggered alarms.
Software & Data Management
The HLD-25 features an embedded 4.3″ capacitive touchscreen interface with intuitive menu navigation and real-time graphing of temperature, flow rate, and system status. It supports RS485 Modbus RTU and optional Ethernet TCP/IP connectivity for integration into centralized lab automation platforms (e.g., LabVantage, DeltaV, or custom SCADA). Logged data—including setpoint history, actual temperature traces, and alarm events—is stored internally (≥30 days at 1-second intervals) and exportable via USB mass storage in CSV format. Firmware supports configuration locking, user role assignment (Operator/Engineer/Admin), and optional 21 CFR Part 11 compliance packages with electronic signature workflows and immutable audit trails.
Applications
- Temperature-controlled synthesis in jacketed glass reactors (e.g., Grignard, hydrogenation, polymerization).
- Calibration and validation of DSC, TGA, and DMA instruments requiring stable thermal ramping and hold profiles.
- Cooling of high-power lasers, X-ray sources, and CCD detectors where thermal drift affects signal fidelity.
- Environmental stress screening of electronic components and packaging materials across extreme thermal cycles.
- Supporting ASTM D5276 (impact resistance), ISO 6722 (automotive wiring), and USP (thermal analysis of pharmaceuticals).
FAQ
What heat-transfer fluids are recommended for operation above 100 °C?
For temperatures exceeding 100 °C, use certified silicone oils with flash points >250 °C and thermal stability ratings validated for continuous operation at 200 °C. Water/glycol mixtures are limited to ≤95 °C.
Can the HLD-25 maintain temperature stability during rapid ramping?
Yes—the system employs adaptive PID tuning with feedforward compensation to minimize overshoot during ramps of up to 5 °C/min. Stability of ±0.3 °C is guaranteed only during static hold conditions per specification; dynamic accuracy is ±0.8 °C during active ramping.
Is remote monitoring supported out-of-the-box?
Standard RS485 Modbus RTU enables integration with third-party SCADA or BMS systems. Optional Ethernet module provides web-based status dashboard and SNMP trap support.
Does the unit include fluid level and leak detection?
Yes—integrated ultrasonic fluid level sensor triggers audible/visual alerts and halts operation if reservoir falls below 20% capacity. Optional flow-sensor retrofit adds real-time leak detection via differential flow monitoring.
