JULABO SC10000w SemiChill Circulating Chiller

Overview

The JULABO SC10000w SemiChill Circulating Chiller is an industrial-grade, water-cooled temperature control system engineered for high-precision, continuous-duty thermal management in semiconductor fabrication, power electronics testing, automotive R&D, and advanced battery development environments. It operates on the principle of vapor-compression refrigeration with a single-stage R404A-based cycle, integrated electric heating, and closed-loop liquid circulation—enabling stable thermal conditioning across an exceptionally wide operational range of –20 °C to +130 °C. Unlike conventional tap-water cooling systems, the SC10000w eliminates dependency on municipal water supply, reduces facility infrastructure load, and supports sustainable lab operations through recirculated coolant management. Its robust architecture—including stainless-steel fluid pathways, chemically resistant wetted materials (e.g., EPDM seals, PTFE-lined reservoirs), and DIN 12876-1 Class III (FL) safety certification—ensures compatibility with non-conductive dielectric coolants (e.g., Thermal G, deionized water/ethylene glycol blends) required in cleanroom and high-voltage applications.

Key Features

• Wide temperature span (–20 °C to +130 °C) with ±0.1 °C stability at setpoint, achieved via PID-controlled dual-mode (refrigeration + resistive heating) regulation
• 10 kW nominal cooling capacity at 20 °C ambient, scalable to 12 kW heating output for bidirectional thermal ramping
• High-flow, pressure-stable circulation system: 33 L/min max flow rate, adjustable pump pressure up to 4.3 bar, with real-time barometric and volumetric feedback on LED display
• Modular, service-oriented design with front-accessible compressor, condenser, and pump assemblies; integrated overload protection for both refrigeration circuit and circulation motor
• Full-spectrum fluid compatibility: validated for use with water, 30–50% ethylene glycol/water mixtures, and industry-standard non-conductive heat transfer fluids meeting SEMI F57 and IEC 60439 specifications
• Onboard programmable logic: 10-step ramp-soak profiles with time- and temperature-triggered events; resolution of 0.1 °C for both setpoint and display
• Embedded PT100 input port for external process temperature feedback, enabling cascade or master-slave control configurations

Sample Compatibility & Compliance

The SC10000w is explicitly qualified for integration into ISO 14644-1 Class 5–7 cleanrooms and meets key regulatory and industry-specific requirements for critical thermal control. Wetted components conform to USP Class VI biocompatibility standards for elastomers and comply with RoHS 2011/65/EU and REACH Annex XIV restrictions. The unit satisfies DIN 12876-1 Class III (FL) for laboratory equipment with flammable coolant handling capability and carries CE marking under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. Optional Profibus DP-V1 interface enables seamless integration into Siemens PCS7, Rockwell Automation PlantPAx, or Yokogawa CENTUM VP DCS environments—supporting audit-ready operation per FDA 21 CFR Part 11 when paired with JULABO’s certified software package.

Software & Data Management

JULABO’s optional ChillerControl Suite (v4.2+) provides secure remote supervision via Ethernet or RS232, supporting encrypted data logging (CSV/SQL), alarm history with timestamped event tagging, and configurable email/SNMP notifications for out-of-spec conditions. All temperature, pressure, flow, and compressor status parameters are sampled at 1 Hz and archived with GLP-compliant metadata (operator ID, instrument serial, calibration certificate traceability). The software enforces role-based access control (RBAC), electronic signatures, and full audit trail retention for ≥12 months—meeting ISO/IEC 17025:2017 clause 7.7.1 and EU GMP Annex 11 requirements for automated systems in regulated laboratories.

Applications

• Semiconductor wafer probing stations requiring sub-0.2 °C thermal drift during parametric testing (e.g., IDS/IDV characterization)
• EV battery module cycling chambers where precise coolant inlet temperature control prevents thermal runaway propagation
• Laser diode and VCSEL array thermal stabilization in photonic packaging lines
• High-power RF amplifier thermal management in 5G base station validation labs
• Material science rheometry setups demanding simultaneous heating/cooling ramps (e.g., DMA, DSC auxiliary cooling)
• Industrial-scale chromatography column ovens requiring rapid cooldown between gradient runs

FAQ

What coolant types are approved for use with the SC10000w in semiconductor applications?
Deionized water, 30–50% ethylene glycol/water mixtures, and non-conductive dielectric fluids such as Thermal G, Coolanol 20, or Polyalphaolefin (PAO)-based coolants compliant with SEMI F57 conductivity limits (<1 µS/cm) are fully supported.
Does the SC10000w support external temperature feedback for closed-loop process control?
Yes—the unit includes a factory-integrated PT100 input channel (2-wire or 4-wire) for connection to external process sensors, enabling cascade control architectures per DIN EN 61508 SIL 2 functional safety guidelines.
Is the R404A refrigerant charge compliant with current EU F-Gas Regulation (EU) No 517/2014?
The 1.8 kg R404A charge (GWP 3922) falls within allowable thresholds for stationary refrigeration equipment installed prior to 2020; however, JULABO offers R450A retrofit kits (GWP <150) for new installations targeting F-Gas Phase-down compliance.
Can the SC10000w operate continuously at –20 °C ambient?
No—the minimum recommended ambient temperature is +5 °C. Operation below this threshold requires auxiliary heating of the condenser water loop or installation in climate-controlled mechanical rooms per DIN 12876-1 Section 6.3.2.
What is the maximum allowable backpressure at the chiller outlet when connected to external equipment?
The system is rated for continuous operation at up to 4.3 bar static discharge pressure; sustained backpressures exceeding 4.5 bar may trigger automatic pump shutdown to protect impeller integrity and seal life.
