JULABO SemiChill SC Series Programmable Temperature Circulating Chiller

Overview

The JULABO SemiChill SC Series is a high-performance, programmable temperature circulating chiller engineered for precision thermal management in demanding industrial and laboratory environments. Utilizing a dual-mode refrigeration-heating system with cascade compressor architecture and electric resistance heating, the SC Series delivers stable, repeatable temperature control across an exceptionally wide operating range of –20 °C to +130 °C. Its robust design integrates high-efficiency heat exchangers, corrosion-resistant fluid pathways (316 stainless steel wetted parts and chemically inert polymer components), and intelligent thermal load adaptation—enabling continuous operation under high-duty-cycle conditions typical in semiconductor process tooling, EV battery testing, power electronics validation, and advanced materials R&D. Unlike conventional chillers limited to sub-ambient cooling, the SemiChill SC Series maintains tight thermal setpoint fidelity regardless of ambient load fluctuations or fluid composition changes—critical for applications requiring traceable, GLP-compliant thermal conditioning.

Key Features

• Wide operational temperature span: –20 °C to +130 °C with ±0.1 °C stability (measured at reservoir, 23 °C ambient, no external load)
• Modular platform with five base configurations (SC2500, SC5000, SC10000) supporting scalable refrigeration (2.5–10 kW) and heating (0.9–12 kW) capacities
• High-flow, pressure-regulated circulation pump delivering up to 33 L/min at 4.3 bar; flow and pressure adjustable via intuitive keypad with real-time bar-graph display
• Dual-sensor liquid level monitoring with audible/visual low-level alarm and automatic pump shutdown to prevent dry-run damage
• Integrated safety architecture: overpressure protection, motor overload cutoff, refrigerant circuit high-pressure cutout, and heater dry-fire prevention
• Fluid compatibility with deionized water, 30–50% ethylene glycol/water mixtures, and specialized heat transfer fluids (e.g., Thermal G™)
• Front-panel 7-inch TFT touchscreen with multilingual UI, real-time trend logging, and configurable alarm thresholds

Sample Compatibility & Compliance

The SemiChill SC Series accommodates a broad spectrum of process fluids and thermal loads without compromising stability or longevity. All fluid-contact surfaces are constructed from electropolished AISI 316 stainless steel and FDA-compliant fluoropolymer seals, ensuring compatibility with aggressive coolants and preventing leaching or galvanic corrosion. The system meets EU directives CE 2014/30/EU (EMC) and 2014/68/EU (PED), conforms to RoHS 2011/65/EU, and is manufactured under ISO 9001:2015 quality management systems. For regulated environments—including pharmaceutical QC labs, automotive Tier-1 validation centers, and semiconductor fab support utilities—the chiller supports optional 21 CFR Part 11-compliant software modules with electronic signatures, audit trails, and user access level controls (admin/operator/guest). It is routinely deployed in ASTM E2877-compliant thermal cycling tests and ISO 16750-4 environmental stress screening protocols.

Software & Data Management

JULABO’s proprietary CoolSoft™ v4.2 firmware enables full remote supervision via Ethernet (TCP/IP), USB, or optional Wi-Fi module. The embedded controller records time-stamped temperature, pressure, flow, and power consumption data at user-defined intervals (1 sec to 60 min), storing up to 16,000 data points locally. Export formats include CSV and XML for integration with LIMS, MES, or SCADA platforms. Optional PC-based CoolControl™ software provides multi-unit dashboard visualization, automated report generation (PDF/Excel), and deviation alerting with email/SMS notification. All configuration changes and operational events are logged with timestamp, operator ID, and parameter delta—fully satisfying GLP/GMP documentation requirements for equipment qualification (IQ/OQ/PQ) and routine performance verification.

Applications

• Semiconductor manufacturing: temperature stabilization of photolithography steppers, etch tools, and wafer bonders requiring ±0.05 °C short-term stability
• Electric vehicle development: thermal cycling of battery modules (UN 38.3 T1–T5), power inverters, and DC fast-charging interfaces
• Automotive component testing: climate simulation for ADAS sensors, LED headlamps, and fuel cell stacks per ISO 16750-4
• Materials science: controlled-cure profiling of composites, adhesives, and thermosets using ramp-soak-hold profiles
• Pharmaceutical R&D: jacketed reactor temperature control during synthesis and crystallization studies compliant with USP analytical instrument qualification
• Academic research: cryo-TEM sample preparation, superconductivity experiments, and laser cavity cooling where fluid purity and thermal inertia are critical

FAQ

What fluid types are approved for use with the SemiChill SC Series?

Deionized water, aqueous ethylene glycol solutions (30–50% v/v), and commercial heat transfer fluids such as Thermal G™ or Syltherm XLT are fully compatible. Avoid chlorinated solvents, acetone, or mineral oils.
Does the SC Series support external temperature feedback control?

Yes—via optional Pt100 or thermocouple input (type K/J/T), enabling closed-loop control at the process point rather than reservoir-only regulation.
Is remote monitoring and control possible without additional hardware?

Standard Ethernet interface enables direct IP-based access; no gateway or converter is required for integration into existing lab networks.
How is calibration traceability maintained for regulatory audits?

Factory calibration certificates are NIST-traceable; field recalibration can be performed using external reference probes, with all adjustments recorded in the secure audit log.
Can the unit operate continuously at maximum refrigeration load?

Yes—designed for 24/7 operation at rated capacity when installed with adequate ventilation and coolant supply per manufacturer specifications (min. 15 °C inlet water @ 3 bar for water-cooled models).
