Overview
The Titan HLD-100S is an integrated dynamic high-low temperature circulating chiller engineered for precision thermal control in demanding laboratory and pilot-scale applications. It combines high-capacity heating and cooling within a single compact unit, utilizing a dual-mode refrigeration system with cascade compressor architecture to achieve stable operation across an exceptionally wide temperature span—from −45 °C to +250 °C. Unlike conventional chillers limited to sub-ambient or ambient-plus ranges, the HLD-100S employs a proprietary heat exchange manifold and PID-controlled electric heating elements synchronized with multi-stage refrigerant circuits. This architecture enables seamless transition between cooling and heating modes without thermal lag or overshoot, making it suitable for temperature-programmed processes such as reaction calorimetry, material aging studies, and dynamic viscosity testing under controlled thermal stress.
Key Features
- Integrated dual-function design: Simultaneous 10,000 W cooling and 10,000 W heating capacity ensures rapid thermal response and bidirectional control without external auxiliary units.
- Air-cooled condensing system eliminates dependency on facility water supply—ideal for laboratories with limited infrastructure or mobile test setups.
- High-stability temperature regulation: Achieves ±0.1 °C stability over full range via adaptive PID algorithms with real-time sensor feedback from dual Pt100 probes (bath and outlet).
- Industrial-grade circulation system: Stainless steel pump head, pressure-rated to 6.5 bar, delivers up to 110 L/min flow at low backpressure—compatible with jacketed reactors, calorimeters, and inline spectroscopy cells.
- 20 L insulated reservoir with level monitoring, corrosion-resistant interior coating, and vapor-tight lid to minimize evaporation and fluid degradation during extended high-temperature operation.
- Continuous-duty rated motor and reinforced compressor mounts ensure uninterrupted operation for 72+ hours under nominal load—validated per IEC 61000-6-2 EMC and IEC 60068-2 environmental stress protocols.
Sample Compatibility & Compliance
The HLD-100S supports circulation of silicone oil (up to 300 °C flash point), ethylene glycol/water mixtures, and specialized heat transfer fluids compliant with ASTM D6793 and ISO 6743-20. Its fluid path is constructed from electropolished 316L stainless steel and PTFE-sealed fittings, ensuring compatibility with aggressive solvents and low-volatility media. The unit complies with CE marking requirements (2014/30/EU EMC Directive, 2014/35/EU LVD Directive), RoHS 2011/65/EU, and meets essential safety provisions of UL 61010-1 for laboratory equipment. Optional IQ/OQ documentation packages are available to support GLP and GMP validation workflows, including traceable calibration certificates aligned with ISO/IEC 17025-accredited reference standards.
Software & Data Management
Equipped with a 7-inch capacitive touchscreen HMI running embedded Linux OS, the HLD-100S provides intuitive local programming of ramp-soak profiles, multi-step sequences, and alarm thresholds. Standard RS485 (Modbus RTU) and optional Ethernet (TCP/IP) interfaces enable integration into SCADA systems and LIMS platforms. Logged data—including bath temperature, outlet temperature, flow rate, compressor discharge pressure, and power consumption—is timestamped and stored internally (32 GB eMMC) for ≥12 months at 1-second resolution. Audit trail functionality complies with FDA 21 CFR Part 11 requirements when paired with Titan’s optional SecureLog™ software module, which enforces user role-based access, electronic signatures, and immutable export to CSV/PDF formats.
Applications
- Controlled-temperature synthesis in jacketed glass reactors (5–50 L volume)

- Stability testing of pharmaceutical formulations under ICH Q1A(R3) guidelines
- Calibration of thermocouples, RTDs, and infrared sensors across extended ranges
- Supporting DSC, TGA, and rheometry instrumentation requiring precise external thermal coupling
- Environmental stress screening of electronic assemblies (MIL-STD-810G, Method 502.6)
FAQ
What heat transfer fluids are recommended for operation above 150 °C?
Silicone oils meeting Dow Corning® 200 Fluid specifications (e.g., viscosity grade 100 cSt) or Shell Heat Transfer Oil S2 X are validated for continuous use up to 250 °C. Ethylene glycol–water blends are restricted to ≤120 °C.
Can the HLD-100S maintain ±0.1 °C stability at both −45 °C and +250 °C simultaneously?
Stability specification applies individually at any setpoint within the operating range; full-range stability is verified per ISO 17025-accredited test reports using NIST-traceable reference thermometers.
Is remote monitoring supported via cloud platform?
Yes—via Titan CloudLink gateway (optional accessory), enabling secure TLS 1.2–encrypted telemetry, email/SMS alerts, and historical trend visualization through web dashboard.
What maintenance intervals are required for continuous 24/7 operation?
Compressor oil analysis and filter replacement every 6,000 operating hours; annual calibration of all critical sensors by authorized service center.
Does the unit include freeze protection for low-temperature operation?
Yes—integrated low-temperature cut-off logic prevents pump cavitation and refrigerant slugging below −45 °C; automatic defrost cycle initiates upon detection of evaporator frost accumulation.
