Zhicheng ZXMP-A1150 Ten-Stage Programmable Temperature and Humidity Controlled Incubator

Overview

The Zhicheng ZXMP-A1150 is a precision-engineered temperature and humidity controlled incubator designed for rigorous life science applications requiring stable, programmable environmental conditions. Utilizing fuzzy logic control architecture and integrated high-fidelity sensing, it maintains tightly regulated thermal and hygroscopic profiles across its 150 L chamber volume. The system operates on a dual-loop control principle: independent PID-regulated refrigeration (R134a, frost-free air-cooled) and steam-based humidification with secondary water reservoir auto-refill—enabling continuous unattended operation over extended cycles. Its operational envelope spans 0–65 °C and 40–98 %RH, with temperature uniformity ≤±1 °C (at 37 °C) and humidity uniformity ≤±5 %RH, meeting baseline requirements for ISO 14644-1 Class 7 cleanroom-adjacent environments and supporting GLP-compliant microbial culture, BOD incubation, and biostability testing per USP and ISO 8573-1 Annex C.

Key Features

• Ten-stage, eighteen-step programmable sequence control—supports complex multi-phase protocols including ramp-hold, stepwise transitions, and repeat cycling
• Fuzzy logic microprocessor controller with LCD interface, real-time clock, power-loss recovery, and parameter password protection
• High-resolution sensing: 0.1 °C temperature resolution; 0.1 %RH humidity resolution; calibrated against NIST-traceable references
• Frost-free refrigeration system with variable-speed compressor and thermal load compensation algorithm
• Two-tier water supply architecture: primary reservoir + secondary auto-fill tank—eliminates manual refilling during long-term runs
• Dual independent safety layers: adjustable overtemperature limiter (30–80 °C), fixed overheat cut-off, leakage current protection, and compressor overload safeguard
• Self-diagnostic suite: low-water-level alert, sensor fault detection, upper/lower limit deviation alarms, and power-interruption logging
• Optimized airflow design: tangential turbine blower with laminarized duct geometry ensures ≤±1 °C spatial uniformity at working volume
• Chamber construction: electropolished stainless steel interior, tempered glass inner door, double-wall insulated outer casing

Sample Compatibility & Compliance

The ZXMP-A1150 accommodates standard microbiological and cell culture vessels—including Petri dishes, multiwell plates, Erlenmeyer flasks (up to 2 L), and serum bottles—on two adjustable electropolished stainless steel shelves (expandable to four). Its chamber geometry (500 × 460 × 650 mm) supports ISO/IEC 17025-aligned validation protocols. The unit complies with IEC 61000-6-3 (EMC emissions), IEC 61000-6-2 (immunity), and GB/T 14710 (Chinese environmental testing standards). While not certified to UL/CSA or CE for North American/EU markets without regional adaptation, its control architecture and alarm hierarchy align with FDA 21 CFR Part 11 data integrity prerequisites when paired with optional RS-232 logging and timestamped event records.

Software & Data Management

Equipped with an RS-232 serial interface (optional), the incubator enables bidirectional communication with external SCADA or LIMS platforms for remote parameter setting, real-time monitoring, and automated audit trail generation. When interfaced with validated third-party software (e.g., LabVIEW-based acquisition modules), it supports time-stamped CSV export of temperature/humidity logs, alarm timestamps, and operational state transitions—facilitating 21 CFR Part 11-compliant electronic record retention. Optional embedded thermal printer provides hard-copy verification of cycle completion, deviation events, and calibration status. All user-modifiable parameters—including setpoints, ramp rates, hold durations, and alarm thresholds—are stored in non-volatile memory with write-protection via four-digit PIN.

Applications

This incubator serves as a core platform for regulatory-grade biological process support: bacterial and fungal cultivation (ASTM D3273, ISO 846), BOD₅ testing (APHA 5210B), vaccine stability studies (ICH Q5C), tissue explant maintenance, insect rearing (EPPO PM 7/102), and plant growth assays under controlled hygrothermal stress. Its precise humidity control enables reproducible mycological sporulation studies, while the programmable profile engine supports accelerated aging protocols for medical device packaging validation (ISO 11607-1 Annex B). In academic and industrial QC labs, it functions as a reference environment for media performance qualification and environmental challenge testing.

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The unit is rated for uninterrupted use within ambient conditions of 5–35 °C per GB/T 14710 Clause 4.3.
Can humidity be maintained below 40 %RH?
No—the humidification system is optimized for 40–98 %RH; sub-40 %RH operation requires external desiccant integration.
Is the RS-232 interface compatible with Modbus RTU protocol?
The native protocol is proprietary ASCII command set; Modbus conversion requires external gateway hardware.
How often does the water reservoir require maintenance?
With secondary auto-fill enabled, full reservoir replenishment is typically required every 14–21 days under continuous 95 %RH operation.
Does the unit support IQ/OQ documentation packages?
Factory-supplied validation templates (DQ/IQ/OQ checklists) are available upon request, aligned with GAMP 5 Annex A guidelines.
