Overview
The LAUDA UC 2 Ultracool Advanced Energy-Efficient Circulating Chiller is an industrial-grade, split-system refrigeration unit engineered for precision temperature control in demanding laboratory and production environments. Based on LAUDA’s proprietary thermodynamic architecture and optimized for low-GWP refrigerants (R-513A), the UC 2 employs a variable-speed scroll compressor, electronically controlled expansion valve (EEV), and adaptive fan speed regulation—enabling dynamic load-matching and minimizing energy waste across partial-load operating conditions. Its core function is to maintain stable coolant supply to external equipment—such as lasers, spectrometers, plasma sources, or CNC spindles—by recirculating temperature-regulated water-glycol mixtures within a closed loop. Designed in full compliance with EU Ecodesign Directive (EU) 2016/2281 and EN 14511-2:2019, the UC 2 achieves a Seasonal Energy Performance Ratio (SEPR) exceeding 5.2—well above the current regulatory threshold of 3.6—making it suitable for installations requiring sustainability certification under ISO 50001 or corporate ESG reporting frameworks.
Key Features
- Energy-optimized operation delivering up to 50% lower power consumption versus conventional chillers under comparable thermal loads and ambient conditions
- Split-system configuration with remote condenser unit, enabling flexible installation in space-constrained labs or noise-sensitive areas
- High-pressure circulation pump (5.5 bar max) and robust flow rate (68 L/min at 12 m head) supporting long-loop applications and multi-device distribution networks
- Integrated 12 L stainless-steel reservoir with level sensor, anti-corrosion coating, and integrated air venting system
- IP54-rated electrical cabinet for indoor/outdoor deployment—certified for operation in ambient temperatures from +5 to +40 °C and relative humidity ≤ 90% non-condensing
- Real-time monitoring via built-in Ethernet port and RS485 interface; compatible with Modbus TCP/RTU for integration into SCADA and MES platforms
Sample Compatibility & Compliance
The UC 2 is designed for continuous-duty operation with aqueous glycol solutions (up to 35% v/v propylene glycol) and deionized water. It maintains thermal stability (±0.5 °C) over its full operational range (–10 to +35 °C), meeting critical requirements for laser cooling, analytical instrumentation, and process validation workflows. The chiller complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emissions), carries CE marking per Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, and conforms to UL 61010-1:2012 (3rd ed.) for North American markets. Optional GMP-compliant documentation packages—including Factory Acceptance Test (FAT) reports, IQ/OQ protocols, and 21 CFR Part 11–ready audit trails—are available upon request for regulated pharmaceutical and biotech applications.
Software & Data Management
The UC 2 integrates natively with LAUDA Cloud—a secure, ISO/IEC 27001-certified platform for remote device management. Users access real-time performance metrics (compressor runtime, energy kWh, delta-T, flow status), configure setpoints, and receive predictive maintenance alerts via web dashboard or mobile app. All data logs are timestamped, digitally signed, and exportable in CSV or PDF format for GLP/GMP traceability. Firmware updates are delivered over-the-air with rollback capability and version-controlled change logs. For on-premise deployments, LAUDA’s LabSoft software provides local HMI functionality—including trend analysis, alarm history, and user-level access control (admin/operator/guest roles)—and supports direct linkage to LabArchives ELN and Thermo Fisher SampleManager LIMS via RESTful API.
Applications

- Materials testing: Tensile testers, rheometers, and DSC instruments demanding precise thermal conditioning
- Electronics manufacturing: UV-curing lines, solder paste reflow ovens, and PCB drilling spindles
- Life sciences: Mass spectrometer ion sources, NMR probe cooling, and cell culture bioreactor jackets
- Automotive R&D: Battery thermal cycling chambers, EV motor test benches, and brake dynamometer cooling loops
FAQ
What is the minimum allowable coolant temperature for continuous operation?
The UC 2 is rated for continuous operation down to –10 °C outlet temperature using a 30% propylene glycol/water mixture. Below –10 °C, antifreeze concentration must be increased and verified against freezing point depression curves.
Does the UC 2 support dry-run protection for the circulation pump?
Yes—the integrated flow sensor triggers automatic shutdown if flow drops below 15 L/min for >10 seconds, preventing cavitation and thermal overload.
Can the chiller be integrated into a building management system (BMS)?
Yes—via Modbus TCP over Ethernet or BACnet/IP (optional firmware module), enabling status reporting, setpoint override, and fault logging within third-party BMS environments.
Is remote firmware update capability included as standard?
Yes—over-the-air (OTA) firmware updates are enabled by default through LAUDA Cloud; no local PC connection is required.
What is the expected service interval for the variable-speed compressor?
Under typical lab usage (8 hrs/day, 5 days/week), LAUDA recommends preventive maintenance every 12 months, including oil analysis, refrigerant leak check, and EEV calibration verification.
