ChemTron CCP Automotive Coolant Circulation Pump Performance Test Bench

Overview

The ChemTron CCP Automotive Coolant Circulation Pump Performance Test Bench is an engineered thermal-fluid test platform designed for rigorous functional validation of automotive coolant pumps, electric motor-driven pump assemblies, and integrated thermal management systems. It operates on a closed-loop, pressurized circulation principle, delivering precise, stable, and dynamically controllable temperature profiles across wide operational ranges—from cryogenic antifreeze conditions (–40 °C) to high-temperature engine simulation (up to +150 °C). Unlike generic temperature chambers or bath circulators, the CCP integrates real-time flow, pressure, and thermal monitoring within a single system architecture—enabling simultaneous measurement of hydraulic performance (flow rate, differential pressure, power consumption) and thermal response under realistic duty cycles. Its design adheres to core requirements defined in ISO 20685 (road vehicle thermal management testing), SAE J2223 (cooling system component test procedures), and supports traceable calibration per ISO/IEC 17025-accredited practices.

Key Features

• 5.7″ industrial-grade color touchscreen HMI with intuitive workflow navigation and multi-parameter real-time visualization (temperature, flow, pressure, power)
• EHC (Enhanced Hierarchical Cooling) segmented heat exchange technology—optimizes thermal ramp rates up to 2 K/min while maintaining long-term compressor reliability and refrigerant efficiency
• ACC (Active Condensation Control) dynamic refrigeration algorithm—enables active cooling even at elevated setpoints (>90 °C), eliminating thermal overshoot during rapid cooldown transitions
• ICC (Intelligent Cascade Control) digital PID architecture—achieves ±0.05 °C stability over extended durations, validated per ASTM E220–22 calibration protocols
• Dual-mode intelligent circulation pump—supports constant-flow, constant-pressure, or programmed ramped pressure profiles; compatible with brushless DC and AC induction motors
• Hydraulic-sealed wet-end design—certified for direct use with ethylene glycol-based antifreeze (e.g., Thermal HL80) and mineral hydraulic oils without fluid degradation or seal swelling
• Integrated 5-µm inline loop filtration—prevents particulate ingress into test specimens and maintains fluid integrity over thousands of thermal cycles
• Front-access operator interface with rear-mounted quick-connect fluid ports—streamlines integration into existing test cells and reduces footprint interference
• Multi-protocol communication suite—native support for RS485 (Modbus RTU), Ethernet (Modbus TCP), and OPC UA for SCADA and MES-level data aggregation

Sample Compatibility & Compliance

The CCP platform accommodates a broad spectrum of coolant pump configurations—including centrifugal, gerotor, and electrically commutated (EC) types—across OEM and Tier-1 development environments. Its fluid compatibility extends to standard automotive antifreezes (ASTM D3306, JIS K2234), biodegradable ester-based coolants, and high-temperature synthetic heat transfer fluids. All models comply with CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. The control software architecture supports audit trails, electronic signatures, and user access levels aligned with FDA 21 CFR Part 11 and EU Annex 11 expectations for regulated R&D laboratories. Calibration certificates are provided with NIST-traceable references for temperature, pressure, and flow transducers.

Software & Data Management

Built-in firmware includes configurable test sequence scripting, automated pass/fail logic based on user-defined thresholds (e.g., pressure drop vs. flow rate, thermal lag time), and timestamped raw data export in CSV and HDF5 formats. Optional ChemTron TestSuite™ software adds GLP-compliant reporting, statistical process control (SPC) charts, and integration with LabArchives ELN or Siemens Opcenter Quality. All system logs—including alarm history, maintenance intervals, and compressor runtime—are stored locally with automatic backup to network shares. Remote access via TLS-secured web interface enables off-site monitoring and parameter adjustment without compromising firewall integrity.

Applications

• Functional endurance testing of e-coolant pumps under combined thermal cycling (–40 °C ↔ +150 °C) and pressure load (0.5–3.2 bar)
• Validation of pump-motor thermal coupling behavior during fast-transient EV battery cooling scenarios
• Low-temperature flow characterization of next-generation low-viscosity coolants below –30 °C
• Development and verification of smart pump control algorithms using real-time feedback from integrated sensors
• Thermal shock resistance assessment of ceramic bearing assemblies and polymer impellers
• Support for ISO 8528-3 transient load testing and VDA 6.3 process audits in supplier qualification workflows

FAQ

What coolant fluids are certified for use with the CCP system?
Thermal HL80, Shell Therminol VP-1, and ASTM D3306-compliant ethylene glycol/water blends (up to 60% concentration) are fully supported. Hydraulic oils meeting ISO VG 32 specifications may also be used where high-temperature stability is required.

Can the CCP operate continuously at –40 °C with full pressure and flow capacity?
Yes—models equipped with dual-stage compressors and integrated secondary heat exchangers maintain rated flow (26–80 L/min) and pressure (0.5–3.0 bar) at –40 °C, subject to fluid viscosity limits and proper pre-cooling ramping.

Is the system compliant with FDA 21 CFR Part 11 for regulated pharmaceutical thermal testing?
While primarily engineered for automotive applications, the CCP’s firmware and optional TestSuite™ software include electronic signature, audit trail, and role-based access controls that satisfy key technical requirements of 21 CFR Part 11 for non-clinical laboratory use.

How is temperature uniformity verified across the test loop?
Uniformity is characterized per ASTM E740 using three calibrated PT100 sensors placed at inlet, midpoint, and outlet of the primary circuit. Typical deviation remains ≤ ±0.15 °C under steady-state operation at ±0.05 °C setpoint stability.

Does ChemTron provide IQ/OQ documentation packages for GMP environments?
Yes—validated installation qualification (IQ) and operational qualification (OQ) protocols, including sensor calibration records, alarm response verification, and loop integrity tests, are available upon request for GxP-aligned deployments.
