Titan HLC-0580E Integrated Low-Temperature to High-Temperature Circulating Chiller

Overview

The Titan HLC-0580E 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 vapor-compression technology with independent PID-controlled heating and cooling circuits, enabling seamless operation across a broad temperature span—from cryogenic −80 °C up to +100 °C. Unlike modular or external-coil systems, the HLC-0580E integrates compressor, condenser, expansion valve, evaporator, immersion heater, reservoir, circulation pump, and digital controller into a single compact footprint. Its water-cooled condenser design ensures stable performance under ambient conditions where air-cooled units may suffer from thermal drift or capacity derating—particularly critical during extended high-load operation at extreme setpoints. The unit is calibrated and validated for continuous-duty cycling, supporting applications requiring long-duration isothermal holds, ramp-and-soak protocols, or dynamic temperature profiling.

Key Features

• Wide operational range of −80 °C to +100 °C with ±0.05 °C temperature stability (measured at reservoir outlet under steady-state conditions with load)
• Integrated dual-circuit thermal management: high-efficiency scroll compressor for refrigeration and 2000 W immersed resistance heater for rapid heating response
• Water-cooled condenser with flow-sensing interlock, compatible with standard facility cooling water (10–30 °C inlet, ≤3 bar supply pressure)
• High-flow circulation system delivering up to 22 L/min at 0.3 bar discharge pressure, optimized for low-backpressure external jackets and jacketed reactors
• 5-liter stainless-steel reservoir with level sensor, anti-corrosion coating, and integrated temperature probe positioned at pump inlet for closed-loop feedback
• Intuitive 7-inch capacitive touchscreen interface with real-time graphing, multi-segment programmable profiles, and event logging
• Robust mechanical architecture including vibration-damped compressor mount, insulated reservoir walls, and sealed electronics compartment rated IP20

Sample Compatibility & Compliance

The HLC-0580E is designed for direct integration with externally jacketed equipment—including rotary evaporators, spectrophotometer cells, calorimeters, material testing chambers, and analytical instrument coolers. Its fluid path is compatible with standard heat-transfer media such as 30% ethylene glycol/water, silicone oil (up to 100 °C), or specialized low-temperature fluids (e.g., ethanol/methanol blends for sub-zero operation). All wetted parts are constructed from 316 stainless steel, PTFE, and EPDM elastomers to ensure chemical compatibility and longevity. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets CE marking requirements under the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. It supports GLP/GMP workflows via optional audit-trail-enabled firmware (Part 11–compliant data export available upon configuration).

Software & Data Management

The embedded controller supports USB and Ethernet connectivity for remote monitoring and control via Titan’s LabLink™ PC software (Windows/macOS). Users can define up to 16-step temperature programs with ramp rates from 0.1 to 10 °C/min, trigger-based actions (e.g., start/stop on external TTL signal), and real-time export of timestamped temperature, flow, and power consumption data in CSV format. Firmware includes configurable alarm thresholds (low flow, high temp, low level, coolant leak detection), email/SNMP alerting (via network gateway), and password-protected parameter locking for SOP adherence. Data logs retain ≥30 days of 1-second-interval records onboard and support scheduled automatic backup to network drives.

Applications

• Temperature control of rotary evaporation systems during solvent removal under reduced pressure
• Thermal stabilization of UV-Vis, FTIR, and fluorescence spectrometers requiring precise cell-jacket temperature regulation
• Material science testing—including DSC sample stage conditioning, rheometer temperature ramps, and polymer crystallization studies
• Pharmaceutical QC/QA processes involving dissolution apparatus calibration and stability chamber auxiliary cooling
• Electronics reliability testing requiring thermal cycling between −40 °C and +85 °C with controlled ramp profiles
• Biotechnology applications such as cold-stage PCR optimization and enzyme kinetics assays at sub-zero temperatures

FAQ

What type of cooling water is required for the water-cooled condenser?

Deionized or softened water with ≤100 ppm total dissolved solids (TDS) and pH 6.5–8.5 is recommended. Facility tap water may be used if hardness is below 150 ppm and chlorine content is minimized.
Can the HLC-0580E maintain −80 °C while circulating fluid through a 5-meter external loop?

Yes—provided the external system has minimal thermal mass and insulation, and the fluid is a suitable low-freezing-point mixture (e.g., 40% propylene glycol/water). Actual achievable temperature at the far end depends on loop length, insulation quality, and ambient heat ingress.
Is the reservoir volume sufficient for integration with large-volume jacketed reactors?

While the 5 L reservoir is optimized for responsiveness and footprint, it is compatible with reactors up to 50 L jacket volume when paired with appropriate flow dynamics and external expansion tanks (optional accessory).
Does the unit support RS485 Modbus RTU communication for PLC integration?

Yes—Modbus RTU over RS485 is supported as a standard interface; register maps and configuration guidelines are provided in the technical manual.
How often does the system require maintenance under continuous operation?

Compressor oil and refrigerant levels are factory-sealed for life under normal use. Recommended annual inspection includes condenser water filter cleaning, reservoir descaling (if using hard water), and verification of pump seal integrity and sensor calibration.
