IKA ICC control pro 20 c Compact Immersion Circulator

Overview

The IKA ICC control pro 20 c is a high-precision compact immersion circulator engineered for stable, reproducible thermal control in laboratory-scale applications requiring external circulation or direct bath immersion. Designed according to DIN 12876 Class III safety standards for heating-only fluid temperature control systems, it employs a dual-sensor architecture—PT100 for primary process control and PT1000 for independent safety cutoff—to ensure compliance with GLP and GMP environmental monitoring requirements. Its core operating principle relies on forced convection via an integrated pressure/suction pump, enabling both internal bath homogenization and external loop circulation (e.g., to jacketed reactors, viscometers, or spectrophotometer cells). The device maintains temperature stability of ±0.01 °C across its full operational range (ambient +10 °C to 150 °C), making it suitable for applications demanding tight thermal regulation without refrigeration capability.

Key Features

• Heating-only immersion circulator with 2100 W input power and stainless-steel construction compliant with DIN 12876 FL classification for flammable media handling
• Dual independent temperature sensing: PT100 working sensor + PT1000 safety sensor with programmable cutoff (0–160 °C)
• TFT touchscreen interface with simultaneous display of process temperature, setpoint, safety limit, and alarm status
• Adjustable pump performance: 0–18 L/min flow rate at 0 bar backpressure; max pressure output 0.3 bar, suction capability up to 0.2 bar
• RS232 and USB interfaces support integration into centralized lab management systems and enable audit-trail-capable data logging per FDA 21 CFR Part 11 requirements
• IP21-rated enclosure ensures protection against vertically falling solids and limited ingress of moisture during routine lab use
• Full 100% continuous-duty rating with thermal overload protection, overvoltage suppression, and dry-run detection
• Calibration-ready design with documented traceability pathways aligned with ISO/IEC 17025 quality system expectations

Sample Compatibility & Compliance

The ICC control pro 20 c is compatible with water, silicone oils, glycol-water mixtures, and other thermally stable heat-transfer fluids rated for operation up to 150 °C. Its stainless-steel bath vessel (sold separately as IB 20 pro) supports volumes up to 18 L and accommodates standard laboratory vessels with diameters up to 292 mm. The system meets DIN 12876 Class III specifications for laboratory heating equipment used in academic, pharmaceutical, and industrial QC laboratories. It supports regulatory workflows requiring documented temperature uniformity, alarm validation, and electronic record integrity—particularly relevant for USP , ASTM E2877, and ISO 17025-accredited testing environments.

Software & Data Management

While the ICC control pro 20 c operates autonomously via its onboard controller, its RS232 and USB ports allow bidirectional communication with third-party SCADA platforms or custom LabVIEW-based monitoring software. Logged parameters—including real-time temperature, pump speed, alarm events, and safety cutoff triggers—are timestamped and exportable in CSV format. When deployed in regulated environments, the device supports user-access-level configuration (admin/operator modes), password-protected parameter changes, and immutable event logs—features essential for FDA 21 CFR Part 11 compliance and internal audit readiness.

Applications

• Temperature stabilization of analytical instruments (e.g., HPLC column ovens, UV-Vis cuvette holders, rheometer sample chambers)
• External circulation for jacketed glass reactors and pilot-scale synthesis systems
• Calibration of temperature-sensitive sensors and transducers under controlled thermal gradients
• Accelerated stability testing of formulations in pharmaceutical development (ICH Q1A)
• Material testing involving viscosity, density, or phase transition measurements requiring precise thermal conditioning
• QC/QA procedures where DIN 12876-compliant thermal control is mandated for method validation

FAQ

Does the ICC control pro 20 c support cooling functionality?
No—it is a heating-only circulator. For combined heating/cooling applications, IKA recommends pairing it with an external chiller via the CC2 cooling coil accessory.
Can this unit be used with silicone oil at 150 °C?
Yes, provided the oil is certified for continuous operation at 150 °C and the bath vessel (IB 20 pro) is installed with appropriate ventilation and spill containment.
Is the PT100 sensor included or optional?
The PT100 working sensor is factory-integrated; the external PT100 probe (PCS.ICC) is sold separately as part of configurable system kits.
What is the minimum recommended bath depth for stable operation?
A minimum liquid depth of 150 mm is required to ensure proper immersion of the heating element and sensor assembly, preventing thermal runaway or dry-run conditions.
How is traceable calibration performed on this device?
Calibration follows a two-point verification protocol using NIST-traceable reference thermometers; documentation templates and uncertainty budgets are available upon request from IKA’s Technical Support team.
