Overview
The Coolium CH-4030T is an integrated, air-cooled, dual-temperature closed-loop circulating chiller engineered for precise thermal management across extreme temperature ranges—from cryogenic cooling at −40 °C to high-temperature heating up to +180 °C. Unlike conventional chillers limited to refrigeration only, the CH-4030T integrates a hermetically sealed refrigeration circuit and a high-efficiency electric heating system within a single compact unit, enabling seamless bidirectional temperature control without media exchange. Its operation relies on a forced-circulation principle: a corrosion-resistant stainless-steel pump delivers thermally stable heat-transfer fluid (e.g., silicone oil or specialized low-temperature glycol blends) through external process equipment—such as jacketed reactors, vacuum ovens, calorimeters, or analytical instrumentation—while maintaining full system integrity via an expansion tank that isolates ambient moisture and vapor pressure fluctuations. This architecture eliminates condensation ingress during sub-zero operation and prevents thermal degradation or misting of organic heat-transfer fluids at elevated temperatures, thereby extending fluid service life and ensuring long-term repeatability in regulated environments.
Key Features
- Wide operational range: −40 °C to +180 °C in a single system—no fluid replacement required across the entire span.
- Air-cooled design eliminates dependency on facility cooling water, simplifying installation and reducing infrastructure requirements.
- Full-brazed plate heat exchanger ensures high thermal efficiency, compact footprint, and resistance to thermal fatigue under cyclic loading.
- Real-time liquid level monitoring with visual indicator and low-level shutdown safeguard prevents dry-run damage to pump and heater elements.
- High-head circulation pump (1.2 bar) supports extended loop lengths and multi-point distribution networks—suitable for centralized lab thermal management.
- Comprehensive safety architecture: over-temperature cutoff, emergency stop, ground-fault detection, over-current protection, and thermal runaway prevention per IEC 60204-1.
- Direct temperature ramping capability: enables rapid transition from high setpoints (e.g., +180 °C) to deep cooling (−40 °C) without intermediate stabilization or manual intervention.
Sample Compatibility & Compliance
The CH-4030T is compatible with a broad spectrum of heat-transfer media—including synthetic silicone oils (e.g., Dow Corning 200 Fluid), polyalphaolefins (PAOs), and low-freezing-point aqueous glycol mixtures—subject to viscosity and flash-point constraints defined in ASTM D6792 and ISO 8502-2. Its fully sealed loop meets GLP/GMP documentation requirements for traceability in pharmaceutical process development (e.g., ICH Q5C stability studies) and complies with electrical safety standards IEC 61010-1 (Laboratory Equipment) and EMC directive 2014/30/EU. Optional data logging modules support 21 CFR Part 11-compliant audit trails when paired with validated software platforms.
Software & Data Management
The embedded PID controller features programmable ramp-soak profiles, real-time deviation alarms, and RS485 Modbus RTU interface for integration into SCADA or LIMS environments. Optional Ethernet-enabled firmware upgrade supports remote monitoring via secure HTTPS endpoints and time-stamped event logging—including temperature excursions, pump status, and fault codes—with configurable retention policies aligned with ISO/IEC 17025 Clause 7.7 requirements for equipment records.
Applications
- Temperature-controlled synthesis in jacketed glass reactors (ASTM E2877-compliant reaction calorimetry).
- Thermal conditioning of HPLC columns, GC injectors, and mass spectrometer ion sources.
- Stability testing chambers requiring simultaneous heating and cooling compensation (USP ).
- Vacuum distillation systems where precise bath temperature governs fractional separation efficiency.
- Material testing rigs for dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC) sample stage conditioning.
- Bioreactor jacket temperature regulation in upstream bioprocessing (compliant with ISPE Baseline Guide Vol. 4).
FAQ
Can the CH-4030T operate continuously across its full temperature range?
Yes—the system is rated for continuous duty at any setpoint between −40 °C and +180 °C, provided ambient conditions remain within specified limits (5–35 °C, ≤80% RH non-condensing).
Is external ventilation required for the air-cooled condenser?
Yes—minimum clearance of 50 cm on all sides and unobstructed airflow above the unit are mandatory to maintain nominal refrigeration capacity and prevent high-head cutout.
What certifications does the CH-4030T carry for international use?
It carries CE marking (EMC & LVD directives), RoHS 2011/65/EU compliance, and factory-issued Declaration of Conformity; optional third-party certification (e.g., UL 61010-1) available upon request.
Does the unit support external temperature feedback control?
Yes—via optional PT100 input channel, enabling cascade control using process temperature measured at the load rather than bath sensor.
How is fluid degradation monitored over time?
While the system does not include inline fluid analysis, its sealed-loop design minimizes oxidation and contamination; users are advised to perform periodic viscosity and acid number testing per ASTM D92 and D974 at intervals defined by fluid manufacturer guidelines.
