JULABO FX30 Industrial Circulating Chiller

Overview

The JULABO FX30 Industrial Circulating Chiller is a high-capacity, water-cooled temperature control system engineered for continuous-duty operation in demanding industrial and laboratory environments. Based on Julabo’s proven refrigeration architecture, the FX30 employs a dual-circuit compression system with optimized heat exchange design to deliver stable, precise cooling across a wide ambient range (−15 °C to +45 °C, optional). Its core function is to supply regulated coolant—typically Thermal GX synthetic heat transfer fluid—at constant temperature and pressure to external equipment such as water-cooled PRESTO dynamic temperature control units, chemical reactors, extruders, vacuum packaging systems, and foam-forming machinery. Unlike benchtop chillers, the FX30 features an open-tank reservoir, integrated bypass valve protection, analog and digital pressure monitoring, and modular scalability—enabling seamless integration into process-critical infrastructure where reliability, thermal inertia management, and long-term operational consistency are non-negotiable.

Key Features

• Robust industrial-grade construction with IP54-rated enclosure suitable for indoor and outdoor installation (rain-resistant housing)
• Modular design supporting three base configurations (FX30/FX50/FX65), allowing capacity expansion without full system replacement
• Automatic bypass valve safeguarding circulation pumps against overpressure and dry-run conditions
• Dual-mode temperature control: cooling-only or heating/cooling (with optional electric heating elements: 3 kW, 6 kW, or 9 kW)
• High-flow, low-pulsation centrifugal pump delivering up to 100 L/min at 2.6 bar (FX30); flow and pressure remain stable under variable backpressure
• Optimized thermal mass via 100 L stainless-steel reservoir with optical level indicator and easy-access fill/drain ports
• Pre-configured compatibility with Thermal GX heat transfer fluid—non-toxic, biodegradable, and rated for continuous operation from −20 °C to +120 °C
• Comprehensive safety suite including high/low temperature cutoffs, flow failure detection, refrigerant leak monitoring, and compressor thermal overload protection

Sample Compatibility & Compliance

The FX30 is designed for closed-loop circulation of compatible heat transfer media—not for direct sample immersion. It interfaces with external process equipment requiring stable coolant supply at defined flow, pressure, and temperature parameters. The unit complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emissions), and meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. All electrical components conform to UL/CSA Class 1 Div 2 standards for non-hazardous locations. When operated with Thermal GX fluid and integrated into validated processes, the system supports adherence to ISO 9001 quality management protocols and GLP-compliant documentation practices. While not intrinsically certified for hazardous areas, it may be deployed in adjacent support zones for chemical or pharmaceutical manufacturing lines operating under cGMP or FDA 21 CFR Part 11–aligned data governance frameworks.

Software & Data Management

The FX30 incorporates a programmable digital controller with intuitive membrane keypad interface and large-backlit LCD display showing real-time values for setpoint, actual temperature, flow rate, outlet pressure, and system status codes. It supports manual and ramp-soak temperature programming with up to 10 segments per cycle. Optional RS485 Modbus RTU or Ethernet TCP/IP connectivity enables integration into SCADA, DCS, or MES platforms for remote monitoring, alarm logging, and trend analysis. Audit-trail functionality—including timestamped parameter changes, alarm events, and maintenance alerts—is available when paired with Julabo’s optional Thermal Studio software (v5.2+), which complies with ALCOA+ principles for electronic record integrity. Data export formats include CSV and PDF; no proprietary cloud dependency is required for local data retention.

Applications

• Primary cooling source for Julabo PRESTO series dynamic temperature control systems in polymer processing, reaction calorimetry, and material testing
• Process cooling in plastic injection molding, extrusion, and blow molding—maintaining die and mold temperatures within tight tolerances
• Thermal management of vacuum packaging machines and foam-blowing equipment in food and packaging industries
• Stabilized coolant supply for exothermic chemical synthesis reactors, distillation columns, and crystallization vessels
• Support infrastructure for laser systems, power electronics, and analytical instrumentation requiring high-volume, low-temperature recirculation
• Environmental test chambers and climatic simulation rigs requiring extended-duration thermal load balancing

FAQ

Can the FX30 operate outdoors in freezing conditions?
Yes—the FX30 can be configured with low-ambient operation option (−15 °C ambient), including compressor crankcase heater, glycol-compatible refrigerant charge, and insulated reservoir jacket.
Is Thermal GX fluid mandatory?
No, but strongly recommended: it eliminates scaling, corrosion, and biological growth risks associated with tap water, extends service intervals, and ensures consistent viscosity and thermal conductivity across the full operating range.
What maintenance schedule does Julabo recommend?
Annual inspection of refrigerant charge, condenser coil cleaning, pump seal integrity check, and fluid analysis (pH, conductivity, contamination) every 12 months or 2000 operating hours—whichever occurs first.
Does the FX30 support 21 CFR Part 11 compliance?
The base unit does not include electronic signature or role-based access controls; however, when connected to Thermal Studio with audit trail license and deployed on validated IT infrastructure, it satisfies key technical controls for Part 11 compliance.
How is flow stability maintained under variable system backpressure?
Through a combination of the integrated bypass valve, pressure-regulated pump head design, and PID-controlled variable-speed drive (optional on FX50/FX65; fixed-speed on FX30 with mechanical regulation).
