Product Overview

The KR‑301 series programmable climatic test chamber is high‑precision environmental simulation equipment built for reliability and stability evaluation of finished goods and raw‑material samples. It reproduces diverse combinations of low‑temperature, high‑temperature, dry and humid atmospheric conditions inside the enclosed working cavity. By exposing test articles to predefined steady‑state or cyclic climate profiles, engineers assess product ageing resistance, operational stability and physical‑property shifts under simulated real‑world service environments.

The product lineup provides multiple inner‑volume variants ranging from 80 L up to 1000 L. Users may select different lowest‑temperature grades ranging from +25 ℃ down to ‑70 ℃ according to project requirements. Equipped with imported core refrigeration and control components, this climatic cabinet delivers stable long‑run performance for production‑floor quality‑control, new‑product formulation research and third‑party lab validation tasks. It is widely deployed across electronics, automotive component, plastic‑polymer, medical‑device, aerospace and building‑material sectors, and fulfils IEC, MIL‑STD, JIS, JESD and multiple GB national environmental‑test specifications.

Core Product Competitive Advantages

Optimised Circulating‑Air Duct & Uniform Internal Climate Distribution
Horizontal directional air‑supply architecture with double‑layer adjustable louvers allows fine‑tuning of airflow direction both vertically and horizontally. Variable‑frequency circulating‑fan motor enables adjustment of wind speed and air volume to fit different test‑sample layouts. Prior computational fluid‑dynamics simulation via SOLIDWORKS and ANSYS helps optimise internal duct geometry, minimising hot‑cold spots across the whole working volume and securing consistent temperature‑humidity conditions for multi‑sample batch testing.
Energy‑Saving Variable‑Frequency Refrigeration System
Adopts well‑known French brand hermetic compressors. Single‑compressor configuration handles down to ‑20 ℃ working condition; dual‑cascade two‑stage refrigeration system supports ultra‑low‑temperature scenarios down to ‑70 ℃. Variable‑frequency compressor drive dynamically adjusts cooling output matching real‑time thermal‑load inside chamber. Imported electronic expansion valve performs precise throttling regulation for refrigerant flow. This architecture reduces unnecessary power consumption while stabilising suction‑discharge pressure of refrigeration circuit and extending compressor service lifespan. Both air‑cooled and water‑cooled condenser options are available.
Multilingual Intelligent Touch‑Screen Control Unit
Original Korean TEMI series colour LCD touch‑screen controller supports bilingual English‑Chinese interface. It stores up to 999 groups of multi‑segment programmable test recipes. Operators may run fixed‑value steady‑state mode or cyclic segmented‑program mode. Built‑in PT100 platinum‑resistance sensors acquire real‑time temperature‑humidity readings. RS‑232 communication port enables PC connection for remote monitoring, data logging and curve recording (data‑printing function is an optional add‑on). Total cumulative runtime counter keeps track of equipment service hours. Comprehensive fault‑diagnosis function displays alarm codes directly on‑screen when abnormalities arise.
Robust Chamber Construction & Complete Accessory Kit
Inner cavity is fabricated from seamless SUS304 stainless‑steel sheet, resisting moisture‑corrosion during long‑term humidity‑cycling experiments. High‑density foam insulation layer minimises thermal‑energy loss. Explosion‑proof vacuum viewing window with internal chamber lighting allows visual sample observation without opening the main door. A standard Φ50 mm test‑through‑hole facilitates external cable‑wiring for powered‑on specimen testing. Two sets of height‑adjustable stainless‑steel sample shelves come as standard delivery.
Multi‑Layer Safety Interlock Protection Mechanism
Hardware‑level protective circuits cover compressor high/low‑pressure safeguard, compressor overload cut‑off, over‑temperature and over‑humidity interlock, fuse protection and water‑shortage alert for humidifying reservoir. When malfunctions occur, the system triggers visual‑audible warning and executes corresponding power‑cut‑off actions to protect test‑specimens and internal hardware. Heavy‑duty levelling casters support easy relocation and stable floor anchoring.

Standard Complete Test Operating Workflow

Pre‑Test Setup
Position climatic chamber on rigid horizontal workshop floor, adjust levelling feet and lock casters. Complete power‑supply connection. Check humidification water‑tank liquid‑level and fill with purified water as required. Inspect door‑sealing gasket condition and confirm safety interlock function works properly. Mount test‑specimens onto adjustable shelves; leave sufficient clearance around samples to guarantee unobstructed internal air circulation. Program target test‑profile via touch‑screen (fixed‑value or multi‑segment cyclic recipe).
Launch Environmental Simulation Test
Close and securely latch main chamber door. Initiate test‑run command. The system automatically activates heating / cooling, humidifying / dehumidifying modules. Closed‑loop PID algorithm maintains target temperature‑humidity set‑points. Real‑time process values and remaining runtime are displayed on HMI. Users can observe sample status through viewing‑window without opening door.
Mid‑Run Monitoring
For long‑duration ageing trials, monitor equipment alarm prompts. When PC data‑logging function is enabled, test‑curve data will be continuously stored on upper‑level computer. Avoid opening chamber door while chamber is under extreme low‑temp or high‑humidity condition to prevent condensation and internal climate disturbance.
Test Completion & Sample Retrieval
Upon finishing pre‑programmed runtime, machine automatically terminates climate‑control sequence. Wait until inner‑chamber temperature moderates towards ambient level before unlocking chamber door. Take‑out test‑samples and carry‑out appearance inspection and functional‑performance measurement, record all observed changes for lab‑report archiving.
Post‑Test Maintenance
Wipe inner‑cavity to remove condensed moisture. Drain humidification water‑tank if equipment will sit idle for extended time. Shut‑down main‑power‑supply. Carry‑out periodic checks for door‑gasket ageing, PT100 sensor calibration status and refrigeration‑system working condition.
