BINDER KMF Series Temperature and Humidity Controlled Chamber

Overview

The BINDER KMF Series Temperature and Humidity Controlled Chambers are precision-engineered environmental test systems designed for reproducible, long-term stability in demanding laboratory and quality assurance applications. Based on the fundamental principles of convective heat transfer and vapor-phase mass balance, these chambers integrate dual-climate control—simultaneous regulation of air temperature and relative humidity—within a thermally insulated, corrosion-resistant stainless-steel enclosure. The proprietary APT.line™ preconditioning chamber ensures uniform thermal distribution by preheating or precooling supply air before it enters the working volume, eliminating cold/hot spots and minimizing temperature overshoot during ramp transitions. Humidity is actively controlled via steam injection, monitored in real time by high-stability capacitive sensors traceable to national metrological standards. This architecture supports strict adherence to ISO 17025-compliant calibration protocols and enables validation under GLP and GMP frameworks.

Key Features

• APT.line™ preheating chamber technology for homogeneous temperature distribution (±0.3 °C typical uniformity at 25 °C, 50 % RH)
• Steam-based humidification system with condensate management and automatic descaling cycle support
• Full AISI 304 stainless-steel interior—including walls, floor, ceiling, and shelves—for chemical resistance and cleanroom-compatible operation
• Dual-sensor redundancy: independent temperature safety device (DIN 12880 Class 3.1) with optical and audible alarm output
• Double-glazed, gas-tight inner door made of safety glass (ESG) with stainless-steel frame and magnetic seal
• Ethernet interface (RJ45) supporting TCP/IP communication for remote monitoring, data logging, and integration into LIMS or MES environments
• Programmable controller with interval-based cycle logic—enabling multi-step profiles with dwell times, ramps, and humidity/temperature interlocks
• 30 mm diameter access port with silicone gasket, positioned on the left side for external probe routing or gas line integration

Sample Compatibility & Compliance

The KMF series accommodates a broad spectrum of sample types—from polymer films and pharmaceutical packaging to electronic assemblies and biological reference materials—without risk of contamination or cross-reactivity. Its fully passivated stainless-steel chamber complies with ISO 10993-5 (cytotoxicity) and USP for extractables testing. Humidity control accuracy (±2 % RH, 20–80 % RH range) meets ASTM E145 and ISO 2419 requirements for leather and textile conditioning. Temperature stability (±0.2 °C over 24 h at setpoint) satisfies ICH Q5C stability testing guidelines. All models are CE-marked and conform to EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions). Optional IQ/OQ documentation packages support FDA 21 CFR Part 11 compliance for electronic records and signatures.

Software & Data Management

BINDER’s optional C-Control software provides validated, audit-trail-enabled operation for regulated environments. It logs timestamped temperature and humidity values at user-defined intervals (down to 1 s), stores configuration changes with operator ID, and generates PDF reports compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Raw data exports are available in CSV and XML formats. Ethernet connectivity allows seamless integration with enterprise data infrastructure via OPC UA or Modbus TCP. Firmware updates are performed over-the-air with cryptographic signature verification to ensure integrity.

Applications

• Accelerated stability testing of pharmaceuticals per ICH Q1A(R3) and Q5C
• Conditioning of composite materials prior to tensile, flexural, or impact testing (ASTM D618, ISO 291)
• Environmental stress screening of PCBAs and microelectromechanical systems (MIL-STD-810H, Method 507.6)
• Calibration and verification of hygrometers and psychrometers against NIST-traceable references
• Long-term storage of hygroscopic reference standards (e.g., saturated salt solutions, silica gel indicators)
• Pre-conditioning of samples for FTIR, XRD, or DMA analysis where moisture content critically affects spectral response

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The KMF series is rated for ambient temperatures up to 30 °C; operation above this requires derating per DIN EN 61000-3-12 and may affect humidity recovery time.
Can the chamber be validated for GMP use?
Yes—BINDER provides factory-issued IQ/OQ protocols, calibration certificates traceable to DAkkS-accredited labs, and 21 CFR Part 11–compliant software options.
Is steam humidification compatible with low-temperature operation?
Yes—the integrated steam generator operates down to 0 °C chamber setpoint; below this, humidity control is disabled by default to prevent condensation-induced corrosion.
How many shelves can be installed in the KMF 720 model?
The standard configuration includes one shelf; up to four additional shelves (part no. 110-800-000) may be added, reducing usable volume proportionally.
Does the Ethernet interface support TLS encryption?
Firmware version 3.2.0 and later support TLS 1.2 for secure HTTP(S) and MQTT communication with enterprise authentication servers.
