Titan HLC-0880E Integrated Low-Temperature to High-Temperature Circulating Chiller

Overview

The Titan HLC-0880E is an integrated low-temperature to high-temperature circulating chiller engineered for precision thermal control in demanding laboratory and industrial R&D environments. It employs a dual-mode refrigeration-heating system based on cascade compressor technology combined with a high-efficiency electric heating circuit, enabling seamless operation across a broad temperature span from −80 °C to +100 °C. Unlike modular or external-coil systems, the HLC-0880E integrates all critical components—including compressors, condenser, expansion valves, PID-controlled heating elements, circulation pump, and insulated bath—within a single compact chassis. This architecture minimizes thermal lag, improves system response time, and enhances long-term stability under continuous duty cycles. The unit is designed for direct connection to external equipment such as spectrophotometers, calorimeters, rotary evaporators, and material testing rigs requiring stable, programmable coolant delivery.

Key Features

• Wide operational range: −80 °C to +100 °C with high reproducibility (±0.05 °C temperature stability at setpoint)
• Integrated water-cooled refrigeration system optimized for ambient conditions up to 35 °C, reducing dependency on facility chilled water infrastructure
• Dual-capacity thermal management: 500 W cooling power at −40 °C (tested per ISO 5151), complemented by 2000 W resistive heating for rapid ramp-up and precise high-temperature control
• High-flow, low-pulsation circulation pump delivering 22 L/min at 0.3 bar discharge pressure, compatible with tubing inner diameters ≥6 mm and pressure drops up to 1.5 bar in external loops
• 8-liter stainless-steel bath with corrosion-resistant interior coating, equipped with level sensor and over-temperature/low-level safety cutoffs
• Industrial-grade PID controller with ramp-soak programming, real-time deviation monitoring, and configurable alarm thresholds
• Front-panel LCD interface with multilingual support (English, German, Japanese), USB data logging port, and optional RS485 Modbus RTU communication for SCADA integration

Sample Compatibility & Compliance

The HLC-0880E is compatible with standard heat-transfer fluids including deionized water, 30–50% ethylene glycol/water mixtures, and silicone oils rated for −80 °C service (e.g., DC200 series). Its sealed fluid path and PTFE-sealed fittings prevent contamination of sensitive analytical instruments. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EMC requirements per EN 61326-1:2013. It supports GLP/GMP workflows through audit-trail-capable firmware (optional upgrade), and its temperature logging functionality aligns with FDA 21 CFR Part 11 data integrity expectations when used with validated software platforms. No hazardous refrigerants are employed; the system uses R508B/R23 cascade blend compliant with current EU F-Gas Regulation Annex I restrictions.

Software & Data Management

Titan provides the optional ChillerControl Suite—a Windows-based application supporting remote configuration, real-time parameter visualization, and scheduled temperature profiling. Logged data (timestamped temperature, flow rate, compressor status, error codes) exports to CSV or XML formats for traceability. The embedded controller stores ≥30 days of 1-second-interval data internally, accessible via USB flash drive. For networked labs, the RS485 interface enables integration into centralized monitoring systems using standard Modbus function codes (03h, 06h, 10h). All firmware updates are delivered via signed binary packages to ensure integrity and version control.

Applications

• Temperature control of NMR probe preamplifiers and cryogen-free magnet cooling circuits
• Stabilization of laser diode mounts and optical tables requiring sub-0.1 °C thermal uniformity
• Cooling of X-ray diffraction detectors and CCD sensors during long-exposure acquisitions
• Thermal conditioning of polymer rheology test fixtures and DSC sample stages
• Process support for pilot-scale extraction, crystallization, and reaction calorimetry
• Environmental simulation for accelerated aging tests per ASTM D7566 and ISO 11341

FAQ

What is the minimum ambient temperature required for reliable operation at −80 °C?
The unit requires ambient temperatures between 15 °C and 35 °C. Below 15 °C, condensation risk increases; above 35 °C, cooling capacity degrades beyond specifications.
Can the HLC-0880E be used with flammable solvents like acetone or THF?
No. Only non-flammable, thermally stable heat-transfer fluids with flash points >100 °C are approved. Refer to Titan’s Fluid Compatibility Matrix (Doc# HLC-FLUID-2024) before selection.
Is external water supply mandatory for the water-cooled condenser?
Yes. A continuous supply of clean, deionized water at 1–3 bar pressure and ≤25 °C inlet temperature is required. An optional closed-loop water-to-water heat exchanger kit is available for facilities lacking municipal water access.
Does the unit support external temperature feedback control?
Yes. The analog input (0–10 V) accepts signals from external PT100 or thermistor probes, enabling jacket or process-loop temperature regulation independent of bath sensor readings.
What maintenance intervals are recommended?
Compressor oil inspection every 12 months; refrigerant leak check annually; pump impeller and seal inspection every 24 months; full calibration verification per ISO/IEC 17025 every 18 months.
