Overview
The Titan HLC-2730S is an integrated high-low temperature circulating bath engineered for precision thermal control in demanding laboratory and industrial R&D environments. It operates on a dual-mode thermoregulation principle—combining vapor-compression refrigeration with resistive electric heating—to deliver stable, programmable temperature control across an exceptionally wide range of −30 °C to +200 °C. Unlike modular or external chiller systems, the HLC-2730S integrates compressor, heater, reservoir, circulation pump, PID controller, and fluid management system into a single compact chassis, minimizing footprint while maximizing thermal responsiveness and long-term operational reliability. Its water-cooled condenser design ensures consistent heat rejection under sustained load, making it suitable for continuous-duty applications where ambient air cooling would compromise stability or capacity.
Key Features
- Wide operational temperature span (−30 °C to +200 °C) enabled by optimized refrigerant circuitry and high-temperature silicone oil compatibility
- High-precision temperature regulation with ±0.03 °C stability (measured at reservoir sensor under steady-state conditions, 1 L/min flow, no external load variation)
- Integrated dual-power thermal actuation: 900 W refrigeration output and 2000 W resistive heating capacity for rapid ramping and overshoot suppression
- 27 L stainless steel reservoir with corrosion-resistant internal coating and level monitoring circuitry
- High-flow, low-pulsation circulation pump delivering 22 L/min at 0.3 bar discharge pressure and 0.2 bar suction capability—compatible with external reactors up to 50 m head
- Water-cooled condenser with flow interlock protection, reducing dependency on ambient air temperature and enabling installation in enclosed or climate-controlled rooms
- Continuous-duty rated architecture with thermal overload protection, refrigerant pressure monitoring, and automatic fault logging
Sample Compatibility & Compliance
The HLC-2730S is compatible with a broad range of heat transfer fluids—including water, 50/50 ethylene glycol/water mixtures, and high-temperature silicone oils (up to 200 °C)—and supports external equipment such as rotary evaporators, calorimeters, spectroscopic cells, and jacketed reactors. Its reservoir and wetted components comply with ISO 8502-3 for surface cleanliness and are constructed from AISI 304 stainless steel and EPDM/PFA-sealed fittings to prevent leaching or degradation. The unit meets CE safety requirements (EN 61000-6-3, EN 61000-6-4) and carries RoHS 2011/65/EU certification. While not intrinsically rated for hazardous locations, optional ATEX-compliant variants are available upon request for solvent-rich environments.
Software & Data Management
The HLC-2730S features an embedded 5.7″ TFT touchscreen interface with real-time graphing, multi-segment ramp/soak programming, and password-protected parameter locking. Internal data logging records temperature, flow rate, compressor status, and error codes at user-defined intervals (1 s to 60 min), storing up to 30 days of traceable operation history. Optional Ethernet or RS485 connectivity enables integration into LabVantage, DeltaV, or custom SCADA platforms via Modbus RTU/TCP. Audit trail functionality complies with GLP and GMP documentation requirements, including operator ID tagging, timestamped event logs, and immutable export to CSV or PDF formats. Firmware updates are performed via USB drive with cryptographic signature verification.
Applications
- Calibration of temperature-sensitive instrumentation (e.g., DSC, TGA, viscometers) requiring traceable thermal stability
- Controlled-rate cooling/heating cycles in polymer crystallization studies and phase transition analysis
- Thermal conditioning of optical benches, laser diodes, and photodetectors during performance validation
- Process simulation in pharmaceutical development—e.g., controlled freeze-thaw cycling of biologics formulations
- Support of ASTM D2570 (low-temperature ductility testing), ISO 3104 (kinematic viscosity), and USP environmental chamber qualification
- Integration with automated synthesis platforms where precise thermal trajectory governs reaction selectivity and yield
FAQ
What heat transfer fluids are recommended for operation above 100 °C?
Silicone-based thermal oils meeting DIN 51524 Part 2 specifications are recommended; avoid mineral oils due to oxidation risk above 120 °C.
Can the HLC-2730S maintain ±0.03 °C stability while supplying external equipment?
Yes—provided the external system’s thermal mass and flow resistance remain within the specified hydraulic envelope (≤50 m head, ≤22 L/min total flow) and fluid volume does not exceed 3× reservoir capacity.
Is remote monitoring supported out-of-the-box?
Standard configuration includes local display and data logging; Ethernet/Modbus connectivity requires optional communication module (order code: HLC-COM-ETH).
Does the unit support 21 CFR Part 11 compliance?
Full electronic record and signature capabilities—including role-based access, audit trails, and electronic signatures—are enabled via the optional Titan LabManager software suite (v3.2+).
What maintenance intervals are recommended for continuous operation?
Refrigerant circuit inspection and pump seal check every 12 months; reservoir cleaning and fluid replacement every 6 months under standard lab use conditions.
