Overview
The Titan HLC-2730E is an integrated, water-cooled circulating chiller engineered for precision temperature control across demanding laboratory and industrial applications. It operates on a dual-mode thermoregulation principle—combining vapor-compression refrigeration with resistive electric heating—to deliver stable, programmable thermal environments from –30°C to +100°C in a single unit. Unlike split-system chillers requiring external condenser loops, the HLC-2730E integrates compressor, expansion valve, evaporator, heater, reservoir, and high-flow circulation pump within a compact, floor-standing chassis. Its design prioritizes thermal inertia minimization and dynamic load compensation, enabling rapid setpoint recovery (<3 min from –20°C to 25°C under 50% load) and sustained stability of ±0.05°C over 24-hour operation—critical for calorimetry, spectroscopy cell conditioning, and material testing per ASTM E1545 and ISO 11357 standards.
Key Features
- Wide operational range (–30°C to +100°C) achieved via optimized R-404A/R-134a dual-refrigerant cascade architecture and high-wattage PTC heating elements (2000 W)
- High-flow circulation system delivering 22 L/min at up to 0.3 bar discharge pressure, supporting multi-point distribution to reactors, jackets, or analytical instruments
- 27-liter stainless-steel reservoir with level sensor, anti-corrosion coating, and integrated air venting to prevent cavitation and gas lock
- Water-cooled condenser design eliminates dependency on ambient air temperature fluctuations—ideal for enclosed labs or cleanrooms where noise and heat rejection are constrained
- Microprocessor-based PID controller with real-time digital display, adjustable ramp/soak profiles, and hardware interlocks for over-temperature, low-flow, and dry-run protection
- Robust mechanical construction: powder-coated steel frame, vibration-damped compressor mount, and IP22-rated electrical enclosure compliant with IEC 61000-6-3 EMC requirements
Sample Compatibility & Compliance
The HLC-2730E is compatible with a broad spectrum of external thermal loads—including jacketed glass reactors (up to 50 L), UV-Vis spectrophotometer sample compartments, differential scanning calorimeters (DSC), and environmental test chambers. Its fluid circuit accommodates standard heat-transfer media such as 30% ethylene glycol/water mixtures, silicone oils (up to 100 cSt), and low-conductivity deionized water (with optional corrosion inhibitor). The unit meets CE marking requirements under the Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. All temperature logging data generated via optional RS485/Modbus RTU output comply with ALCOA+ principles for traceability and may be integrated into GLP/GMP workflows supporting FDA 21 CFR Part 11–compliant audit trails when paired with validated SCADA software.
Software & Data Management
While the HLC-2730E operates autonomously via its front-panel interface, it supports bidirectional communication through an industry-standard RS485 port using Modbus RTU protocol (addressable register map provided in user manual). This enables integration with LabVIEW, MATLAB, or custom Python-based control systems for synchronized thermal profiling and event-triggered data acquisition. Optional TitanLink™ PC software (Windows 10/11) provides real-time graphing, CSV export, alarm history logs, and password-protected parameter locking—facilitating IQ/OQ documentation. No cloud connectivity or proprietary firmware updates are required; all configuration remains local and auditable.
Applications
- Temperature stabilization of NMR probe preamplifiers and cryogen-free magnet cooling circuits
- Controlled-rate cooling/heating in polymer crystallization studies (ISO 10364, ASTM D3418)
- Thermal conditioning of photovoltaic cell test benches during I-V curve tracing
- Process support for pilot-scale synthesis reactors requiring exotherm management between –20°C and 80°C
- Calibration of platinum resistance thermometers (PRTs) and thermocouple reference baths per ISO/IEC 17025
- Long-duration stability testing of optical alignment stages in interferometric metrology setups
FAQ
What fluids are compatible with the HLC-2730E’s circulation loop?
Ethylene glycol/water blends (≤50%), silicone oils (viscosity ≤100 cSt), and inhibited deionized water are approved. Avoid chlorinated solvents, acetone, or high-pH buffers.
Can the unit maintain ±0.05°C stability at 100°C?
Yes—stability specification applies across the full range. At elevated temperatures, the system leverages proportional heating control and reduced refrigerant mass flow to minimize overshoot and drift.
Is remote monitoring possible without third-party hardware?
Yes—RS485 Modbus RTU allows direct connection to PLCs or PCs using standard industrial converters. No gateway or IoT hub is required.
Does the chiller include a filtration system for the reservoir?
A 50-µm inline particulate filter is installed upstream of the pump inlet. Replacement cartridges are available as Titan part #FIL-HLC-01.
What maintenance intervals are recommended?
Compressor oil inspection every 24 months; refrigerant leak check annually; reservoir cleaning and fluid replacement every 12 months under continuous operation.
