Overview
The Titan HLD-25S is an integrated dynamic heating and cooling circulating chiller engineered for precise thermal control across demanding laboratory and pilot-scale applications. Unlike conventional single-mode chillers, the HLD-25S employs a dual-function refrigeration–heating system based on cascade compressor architecture combined with high-efficiency electric resistance heating. This enables seamless, programmable temperature transitions across a broad operational span—from cryogenic conditions at –30 °C to elevated process temperatures up to +250 °C—without requiring external heat sources or coolant swaps. Its air-cooled design eliminates dependency on facility water supply, making it suitable for flexible benchtop deployment in chemistry labs, materials testing environments, and analytical instrument thermal management (e.g., as a temperature-controlled bath for HPLC column ovens, rheometers, or spectroscopic sample cells). The unit operates continuously under load, supporting long-duration stability-critical protocols such as polymer crystallization studies, reaction calorimetry, and accelerated aging tests.
Key Features
- Wide dynamic temperature range (–30 °C to +250 °C) enabled by optimized cascade refrigeration and independent high-power resistive heating (3000 W)
- Air-cooled condensing system—no external water connection required; ideal for facilities with limited utility infrastructure
- High-flow circulation (30 L/min) with adjustable pressure output up to 3 bar, compatible with closed-loop systems featuring narrow-bore tubing or high-backpressure accessories
- Compact reservoir (3 L) constructed from corrosion-resistant stainless steel with integrated level sensor and low-fluid alarm
- Digital PID temperature controller with real-time display, ramp/soak programming, and ±0.3 °C stability under steady-state conditions
- Robust industrial-grade pump assembly rated for continuous 24/7 operation with thermal overload protection and dry-run prevention
Sample Compatibility & Compliance
The HLD-25S is designed to interface with a wide variety of external equipment via standard 1/2″ NPT or G1/2″ threaded ports. It supports circulation of water, water–glycol mixtures (up to 50% v/v), and other non-corrosive, low-viscosity heat transfer fluids compatible with stainless steel and EPDM wetted components. All electrical components comply with IEC 61010-1:2010 for laboratory equipment safety. The unit meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not intrinsically rated for hazardous locations, its sealed refrigerant circuit and overtemperature cutoffs support safe integration into ISO/IEC 17025-accredited testing laboratories. Documentation includes full factory calibration records traceable to NIST-certified references.
Software & Data Management
The HLD-25S features RS485 Modbus RTU communication capability for integration into centralized lab automation platforms. Optional USB-to-serial adapter enables direct connection to Windows-based PCs running third-party SCADA or LIMS software. Temperature setpoints, actual bath readings, pump status, and fault logs can be exported in CSV format for audit-ready recordkeeping. When deployed in regulated environments (e.g., pharmaceutical QC labs), the system supports manual logging protocols aligned with GLP and FDA 21 CFR Part 11 principles—though native electronic signature or audit trail functionality requires external middleware. Firmware updates are performed via secure offline upload to maintain system integrity during validation.
Applications
- Temperature programming for synthetic chemistry reactors and jacketed glass vessels
- Thermal conditioning of viscometers, DSC sample stages, and dynamic mechanical analyzers (DMA)
- Cooling of high-power laser sources, X-ray generators, and mass spectrometer ion sources
- Stabilization of environmental test chambers and humidity-controlled enclosures
- Supporting ASTM D341 viscosity–temperature correlation studies and ISO 2555 thermal conductivity measurements
- Process validation in biopharmaceutical development where precise thermal ramping between sterilization and storage conditions is required
FAQ
What heat transfer fluids are recommended for use with the HLD-25S?
Deionized water is optimal for operation between 5 °C and 95 °C. For sub-zero operation, a 40–50% propylene glycol/water mixture is recommended. Avoid ethylene glycol in labs handling biological samples due to toxicity concerns.
Can the HLD-25S maintain ±0.3 °C stability at 250 °C with external load?
Yes—stability specification applies across the full range when operating within rated cooling/heating capacity limits and using appropriate insulation on external loops.
Is remote monitoring supported out of the box?
Modbus RTU communication is built-in; however, a dedicated PC interface module or PLC gateway is required for real-time remote viewing or control.
Does the unit include a fluid filtration system?
A 50-µm inline particulate filter is installed upstream of the pump to protect internal components; replacement elements are available as service parts.
What maintenance intervals are recommended for continuous operation?
Compressor oil and refrigerant levels should be verified annually; pump seals and fluid quality assessed every 6 months under heavy-duty use.
