IKA C 3000 eco Package Isoperibolic Calorimeter

Overview

The IKA C 3000 eco Package is a fully automated, high-precision isoperibolic bomb calorimeter engineered for reliable determination of gross and net calorific values (higher and lower heating values) of solid and liquid fuels. Designed as the successor to the C 2000 series, it integrates advanced thermal management, real-time multi-point temperature monitoring, and compliance-driven measurement protocols. Its core principle relies on isoperibolic operation—maintaining constant outer jacket temperature while precisely measuring heat release from combustion in a sealed, pressurized oxygen atmosphere within a spherical bomb. This architecture ensures high reproducibility, minimal thermal lag, and robust performance across demanding industrial QA/QC environments—including power generation, cement manufacturing, coal trading, and accredited testing laboratories.

Key Features

• Spherical C 6010 bomb head with enhanced pressure stability and accelerated heat transfer kinetics compared to conventional cylindrical designs
• Integrated touchscreen interface (with optional USB mouse support) enabling intuitive method selection, parameter configuration, and real-time status visualization
• Automated oxygen charging (up to 40 bar), water filling/drainage, and ignition sequence—eliminating manual intervention and operator variability
• Six independent platinum resistance thermometers (Pt100) distributed across inner/outer jackets and bomb housing for comprehensive thermal profiling and drift compensation
• Dual fixed start-temperature options (22 °C and 30 °C) compliant with ISO 1928, ASTM D240, ASTM D4809, ASTM D5865, and GB/T 213
• Modular cooling integration via RC 2 Basic recirculating chiller (included), maintaining jacket temperature stability within ±0.01 K under variable ambient conditions (12–27 °C coolant supply)
• Novel crucible support mechanism enabling rapid, contamination-free sample loading and ash residue handling
• Comprehensive connectivity: Ethernet (for networked LIMS integration), RS232 (balance & printer), USB (storage, peripheral control), SD card slot (offline data backup)

Sample Compatibility & Compliance

The C 3000 eco Package accommodates standard 0.5–1.5 g samples of coal, coke, biomass pellets, waste-derived fuels, petroleum products, and certified reference materials (e.g., NBS 39i benzoic acid). All measurement routines adhere strictly to internationally recognized standards: ISO 1928 (solid mineral fuels), ASTM D240 (petroleum fuels), ASTM D4809 (liquid hydrocarbons), ASTM D5865 (coal and coke), and GB/T 213 (Chinese national standard). The system supports full audit trails, electronic signatures, and metadata logging—enabling alignment with GLP and GMP documentation requirements. Firmware and Calwin software comply with FDA 21 CFR Part 11 principles for electronic records and signatures where configured with user access controls and event logging.

Software & Data Management

Calwin software (v3.0+, included) serves as the central control and evaluation platform. It enables method definition, instrument orchestration, live thermal curve visualization, automatic calculation of gross/net calorific value (including moisture, hydrogen, and sulfur corrections per ASTM D4809), uncertainty estimation, and export to CSV, PDF, or direct LIMS transmission via TCP/IP. All raw sensor data—including time-stamped temperature gradients, pressure profiles, and ignition events—are retained with timestamped metadata. Audit logs record user actions, calibration events, and software updates—supporting traceability in regulated environments. Data encryption and role-based permissions are configurable to meet institutional IT security policies.

Applications

• Quality assurance of coal, lignite, and alternative fuels in thermal power plants
• Batch release testing of cement kiln feedstocks and secondary fuels
• Accredited fuel certification per EN 14918, ISO 18125, and national regulatory frameworks
• R&D of biofuels, refuse-derived fuels (RDF), and hydrogen-blended combustion mixtures
• Interlaboratory comparison studies and proficiency testing programs
• Teaching and demonstration of thermodynamic principles in university physical chemistry labs

FAQ

What standards does the C 3000 eco Package support for net calorific value calculation?
It natively implements correction algorithms per ISO 1928, ASTM D4809, ASTM D5865, ASTM D240, and GB/T 213—including latent heat of vaporization adjustments based on sample moisture, hydrogen, and sulfur content.

Is external cooling mandatory?
Yes—the system requires a continuous coolant supply at 12–27 °C and ≥60 L/h flow rate. The included RC 2 Basic chiller satisfies this requirement under typical lab conditions (ambient ≤30 °C, humidity ≤80 %).

Can the instrument operate without Calwin software?
No. Calwin is required for method execution, data acquisition, and compliance reporting. Standalone touchscreen operation is limited to status monitoring and basic diagnostics.

What maintenance intervals are recommended?
O-ring replacement every 500 firings, bomb hydrostatic testing every 2 years (per ASTM E711), and annual calibration of temperature sensors and pressure transducers using NIST-traceable references.

Does the system support remote monitoring or networked operation?
Yes—via built-in Ethernet port with static IP or DHCP assignment; compatible with centralized lab infrastructure, SNMP monitoring tools, and secure VPN access when deployed behind institutional firewalls.
