Overview
The Titan HLT-2020E 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 high-efficiency vapor-compression refrigeration with proportional-integral-derivative (PID)-controlled resistive heating—to maintain stable thermal conditions from -20°C to +100°C in a single unit. Unlike modular or external-coil systems, the HLT-2020E integrates compressor, condenser, expansion valve, evaporator, heater, circulation pump, and 20-liter stainless-steel reservoir into a compact, floor-standing architecture. Its design targets continuous-duty operation under load variations typical in rotary evaporation, spectrophotometer jacketing, reactor temperature management, and material testing environments where thermal inertia and response time directly impact experimental repeatability.
Key Features
- Wide operational range of -20°C to 100°C enables seamless transition between cryogenic sample conditioning and high-temperature process support without auxiliary equipment.
- 2600 W cooling capacity at 20°C ambient—validated per ISO 5151—ensures effective heat extraction from high-power instruments such as NMR probe coolers or laser sources.
- ±0.05°C temperature stability (measured at reservoir outlet over 2 hours, load constant) meets ASTM E2877 requirements for thermal uniformity in calibration-critical workflows.
- High-flow, low-pulsation circulation system delivers 33.3 L/min at 0.7 bar discharge pressure, supporting multi-point distribution via manifolded loops while maintaining laminar flow characteristics.
- Stainless-steel reservoir with level sensor, leak-detection circuitry, and over-temperature/over-pressure cutouts complies with IEC 61000-6-2 EMC immunity standards and UL 61010-1 safety requirements.
- Integrated water-cooled condenser eliminates dependency on ambient air quality or space-constrained ventilation—ideal for cleanrooms or enclosed utility corridors.
Sample Compatibility & Compliance
The HLT-2020E is compatible with standard laboratory heat-transfer fluids—including deionized water, 30% ethylene glycol/water mixtures, and low-viscosity silicone oils (up to 50 cSt)—within its specified temperature envelope. Fluid compatibility is verified per ISO 8504-2 for corrosion resistance and thermal degradation thresholds. The unit conforms to CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), RoHS 2011/65/EU substance restrictions, and supports GLP/GMP documentation through optional audit-trail-enabled controller firmware (available upon request). All electrical interfaces meet IP20 ingress protection rating; optional IP54 enclosure upgrade available for humid or particulate-prone environments.
Software & Data Management
Equipped with a 4.3-inch TFT touchscreen HMI, the HLT-2020E provides real-time monitoring of reservoir temperature, flow rate, compressor duty cycle, and heater output. Logged data (timestamped, 1-second resolution) is stored internally for up to 30 days and exportable via USB 2.0 to CSV format. RS485 Modbus RTU interface allows integration into centralized SCADA or LabVantage systems for remote setpoint adjustment, alarm forwarding, and preventive maintenance scheduling. Firmware supports configurable alarm thresholds, password-protected parameter locking, and event history with cause-code annotation—fully traceable for FDA 21 CFR Part 11 compliance when paired with validated electronic signature modules.
Applications
- Rotor cooling for high-speed centrifuges and ultracentrifuges requiring sub-zero jacket temperatures.
- Temperature stabilization of UV-Vis, FTIR, and fluorescence spectrometers with Peltier- or liquid-jacketed optics compartments.
- Thermal management of analytical HPLC columns and detectors operating at elevated gradient temperatures (e.g., 80°C method development).
- Process support for pilot-scale bioreactors, jacketed glass reactors, and calorimetry cells requiring dynamic ramp-and-hold profiles.
- Calibration laboratories performing thermometer or RTD verification across extended ranges per ISO/IEC 17025 Clause 6.4.10.
FAQ
What is the recommended maintenance interval for the HLT-2020E?
Annual inspection of refrigerant charge, condenser coil cleanliness, and pump seal integrity is advised; filter replacement every 6 months under continuous operation.
Can the unit operate with pure water below 0°C?
No—pure water freezes at 0°C; use a certified antifreeze mixture (e.g., USP-grade propylene glycol) for sub-zero operation to prevent reservoir or line damage.
Is external water supply required for the water-cooled condenser?
Yes—a stable municipal or closed-loop cooling water source (10–32°C inlet, ≤3.5 bar pressure, ≥1.5 m³/h flow) must be connected per the condenser’s hydraulic specifications.
Does the HLT-2020E support external temperature feedback control?
Yes—via optional PT100 input channel; the controller can accept remote sensor signals for process-jacket or reactor-vessel temperature feedback, enabling cascade control configurations.
How is temperature uniformity verified across the circulation loop?
Uniformity is validated using calibrated Class A PT100 probes at three points: reservoir outlet, mid-loop tap, and return inlet—deviation must remain within ±0.1°C per ISO 17025-accredited internal protocol.
