Overview
The BINDER LIT MK 240 Battery Test Chamber is an engineered environmental test system designed specifically for the safe, repeatable, and standards-compliant thermal stress evaluation of lithium-ion and other electrochemical energy storage devices. Built upon BINDER’s proprietary APT.line™ pre-heating chamber technology, the LIT MK 240 maintains exceptional thermal uniformity and stability across its full operating range of −40 °C to +110 °C — with optional extension to +120 °C under dual independent Class 2 temperature safety supervision per DIN 12880. Unlike general-purpose climate chambers, the LIT MK series integrates battery-specific hazard mitigation as standard: continuous multi-gas monitoring (CO, H₂, O₂), real-time ambient temperature sensing, automatic CO₂-based fire suppression, and a certified pressure-relief mechanism compliant with IEC 62619 and UN 38.3 testing prerequisites. Its robust steel frame, reinforced door locking system, and explosion-resistant viewing window (heated and LED-illuminated) ensure operational integrity during high-risk thermal runaway scenarios.
Key Features
- Dual independent Class 2 temperature safety devices (DIN 12880-compliant), each fully adjustable and independently monitored
- APT.line™ pre-heating chamber architecture ensuring ±0.1 K to ±0.5 K temperature stability and ±0.1 K to ±1.2 K uniformity across the 228 L working volume
- Integrated gas detection suite for CO, H₂, O₂, and ambient temperature — configurable alarm thresholds and automated suppression activation
- Reversible stainless-steel pressure relief valve mounted centrally on the chamber roof, rated for rapid overpressure venting
- Heated, anti-fog, LED-illuminated observation window (508 mm × 300 mm) enabling uninterrupted visual inspection under all thermal conditions
- Condensation protection programming mode to prevent moisture accumulation during low-temperature ramp-down phases
- Fluorine-free refrigerant R-452A and compressor-based cooling system delivering 3.5 K/min average cooling rate (IEC 60068-3-5)
- Touchscreen controller with intuitive time-segment and real-time programming; supports up to 999 cycles with 99 steps per program
Sample Compatibility & Compliance
The LIT MK 240 accommodates battery cells (pouch, cylindrical, prismatic), modules, and small-format packs up to 70 kg total load — distributed across a single stainless-steel shelf or multiple racks (30 kg per rack). Its internal geometry (735 mm W × 700 mm H × 443 mm D) and wide access door support ergonomic loading of prototype and production-grade specimens. The chamber meets essential regulatory frameworks for battery safety validation, including IEC 62619 (industrial batteries), UN 38.3 (transportation safety), and ISO 12405 (electric vehicle battery testing). All thermal performance data are validated per DIN 12880 at 22 °C ±3 °C ambient, with ±10% supply voltage tolerance and 100% fan speed — ensuring reproducibility in GLP- and GMP-aligned laboratories.
Software & Data Management
Control and documentation are managed via the built-in touchscreen interface and BINDER’s APT-COM™ Basic software suite. The internal datalogger captures temperature, gas concentrations, and safety status at user-defined intervals (down to 1 s resolution), storing data in open CSV format for traceability and third-party analysis. USB export enables direct integration into LIMS or statistical process control platforms. Ethernet connectivity supports remote monitoring, firmware updates, and centralized fleet management. Audit trails — including operator ID, parameter changes, alarm events, and safety actuations — comply with FDA 21 CFR Part 11 requirements when used with validated APT-COM™ Professional licensing. Real-time graphical visualization and configurable email/SMS alerts enhance operational responsiveness without compromising data integrity.
Applications
The LIT MK 240 serves critical roles across battery development, quality assurance, and certification workflows: accelerated aging studies under variable thermal profiles; thermal shock testing per IEC 60068-2-14; charge/discharge cycle validation under controlled ambient stress; safety margin evaluation prior to mechanical abuse testing; and pre-certification screening for UL 1642, UL 2580, and GB/T 31485 compliance. Its design supports both R&D labs validating next-generation chemistries (e.g., solid-state, sodium-ion) and production facilities executing 100% incoming cell qualification. The chamber’s modular safety architecture allows seamless integration into larger test benches equipped with cycler synchronization and HV isolation interfaces.
FAQ
What safety certifications does the LIT MK 240 meet out-of-the-box?
It complies with DIN 12880 (temperature safety), IEC 62619 Annex A (battery-specific risk mitigation), and carries CE marking under the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU.
Can the chamber be integrated with external battery cyclers?
Yes — via Ethernet or digital I/O signals (optional module), enabling synchronized thermal profiling with charge/discharge sequences and automated safety interlocks.
Is remote firmware update supported?
Yes, through APT-COM™ Basic or Professional over secure Ethernet; updates preserve calibration history and audit logs.
What is the recommended maintenance interval for gas sensors?
BINDER specifies 12-month calibration verification for CO/H₂/O₂ sensors, with field-replaceable sensor cartridges and documented calibration procedures included in the service manual.
Does the LIT MK 240 support custom alarm logic (e.g., combined gas + temperature thresholds)?
Yes — the touchscreen controller allows multi-condition trigger definitions, including logical AND/OR combinations of gas concentration, temperature deviation, and pressure events.
