Product Overview

The KR‑301 programmable climate test chamber is a versatile environmental‑simulation laboratory instrument. It replicates high‑temperature, low‑temperature, constant damp‑heat and alternating hot‑humid cyclic conditions to assess heat‑resistance, cold‑resistance, dry‑proof and moisture‑proof performance of components and raw‑materials.

Multiple standard inner‑cavity dimensions are offered to match different specimen‑size requirements. The touch‑screen controller supports multi‑segment program editing for unattended cyclic reliability tests. It complies with IEC, MIL‑STD, JIS and JESD industrial specifications, widely used in electronics, auto‑parts, aerospace, chemical, medical‑device and third‑party inspection labs for incoming QC, new‑material R‑D and product certification validation.

Core Product Competitive Advantages

1. High‑quality cabinet construction with anti‑condensation observation window Matte‑textured outer shell with flat non‑protruding door‑handle design. Large‑area insulated multi‑layer glass viewing window is fitted with anti‑sweat heating element to avoid vapour fogging; built‑in high‑brightness internal lamp allows real‑time sample observation without opening the door. Double‑layer sealed structure effectively reduces internal temperature‑energy leakage.
2. Mature refrigeration system with eco‑friendly refrigerant Adopts France Tecumseh fully‑enclosed compressor. Single‑stage refrigeration for‑20 ℃ grade; two‑stage cascade refrigeration for‑40 ℃ ~‑70 ℃ versions. Supports air‑cooled or water‑cooled condensation. Equipped with oil‑water separator; uses R23, R404, R507 environment‑friendly refrigerants for stable long‑cycle operation.
3. Imported multi‑function touch‑screen control unit Korean TEMI580 / TEMI880 colour touch‑screen HMI supports Chinese‑English switching. Stores up to 999 groups of multi‑segment test profiles. Both quick‑jump and slope ramp‑rate modes are selectable. Real‑time PV/SV value display, runtime accumulation recording, fault self‑diagnosis and alarm prompt. Reserved RS232 communication interface supports PC remote monitoring and test‑data recording (recorder optional). PT100 platinum‑resistance sensor delivers precise signal acquisition.
4. Independent water‑supply circulation system Rear‑mounted built‑in water‑tank achieves automatic water‑replenishment and water‑shortage audible‑visual alarm, preventing humidifier dry‑burn risk. Simplifies daily water‑supply maintenance for continuous‑run testing.
5. Optimised air‑circulation & complete safety safeguards Multi‑blade centrifugal wind wheel paired with aluminium‑alloy reinforced shaft builds forced convection air‑loop, improving temperature‑humidity uniformity across test zone. Mobile brake‑casters plus levelling feet for easy relocation and firm positioning. Full‑set protection includes compressor high/low‑pressure safeguard, over‑temp / over‑humidity cut‑off, fuse protection and comprehensive fault warning system.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place equipment on level solid ground, lock brake‑casters and adjust levelling feet. Inspect refrigeration assembly, humidification water‑supply tank, circulating‑fan and full alarm‑protection functions. Arrange specimens on adjustable stainless‑steel shelves; keep sufficient gaps for smooth air circulation. Firmly close chamber door and power‑on main‑unit.
2. Program Parameter Configuration Operate touch‑screen HMI: create or recall saved multi‑segment test profile, configure temperature‑humidity set‑points, dwell‑time and cycle‑quantity. Select ramp‑rate mode (slope / quick). Activate data‑logging function. Wait inner‑cavity climate to stabilise before starting formal test.
3. Execute Climate Environmental Reliability Test Launch test‑program. The unit automatically runs heating, cooling, humidification‑dehumidification cyclic sequences. System continuously logs operating parameters; triggers alarm when abnormal condition occurs. Equipment auto‑stops upon completing preset runtime or cycle‑count.
4. Specimen Retrieval & Result Evaluation Wait cavity temperature rises close to ambient level before opening door. Remove test‑pieces and inspect deformation, performance drift and appearance deterioration. Record inspection data for QC‑reports. Multiple replicate‑specimen tests are recommended for statistically‑reliable assessment.
5. Post‑Test Tidying Clear test‑chamber of sample debris. Check humidifier water‑tank liquid‑level. Reset program‑parameters. Shut‑down main power for long‑term idle‑storage. Periodically inspect door‑seal gasket condition and calibrate PT100 sensor.

Safety‑Operation‑Reminder

Do not open chamber‑door during extreme high‑/low‑temperature running‑cycle to avoid scald or frost‑bite hazard. Reliable equipment‑grounding must be completed before power‑on. Avoid frequent short‑interval power‑on‑off cycles to protect compressor service‑life. Periodically inspect door‑gasket sealing‑performance and humidification‑water‑system cleanliness.
