Overview
The Ying’an Meicheng MC-1000C/BP is an integrated circulating chiller engineered for precision temperature control and stable coolant delivery in laboratory and analytical instrumentation environments. It operates on a closed-loop refrigeration cycle utilizing a variable-frequency compressor to dynamically match thermal load demand—enabling continuous, energy-efficient operation across its full 5–35 °C setpoint range. Unlike on/off cycling chillers, the MC-1000C/BP modulates compressor speed via inverter-driven control, minimizing thermal overshoot, reducing mechanical stress, and achieving ±0.1 °C temperature stability under steady-state conditions. Its water-cooled condenser design eliminates reliance on ambient air exchange, making it suitable for temperature-sensitive or space-constrained lab settings where heat rejection must be managed externally (e.g., via facility cooling towers or dry coolers). The unit is fully self-contained—requiring only electrical power, external coolant supply (deionized or softened water recommended), and connection to the instrument’s cooling jacket or heat exchanger inlet/outlet ports.
Key Features
- Variable-frequency compressor control for adaptive cooling capacity, delivering up to 30% energy savings versus fixed-speed equivalents at equivalent cooling output
- Digital microprocessor-based PID temperature controller with real-time display of setpoint, actual bath temperature, pump pressure, and reservoir level
- High-performance imported circulation pump delivering 6 L/min flow at up to 7 bar maximum pressure; pressure adjustable via integrated regulator
- 15-liter stainless-steel reservoir with level sensor and low-level shutdown protection
- Soft-start compressor activation—ramp-up over 20 seconds—to suppress inrush current and extend component service life
- Integrated casters and compact footprint enabling flexible placement and repositioning within shared laboratory spaces
- Acoustically optimized enclosure and vibration-damped mounting to maintain low operational noise (<55 dB(A) at 1 m)
Sample Compatibility & Compliance
The MC-1000C/BP is compatible with a broad spectrum of analytical and materials testing instruments requiring regulated coolant supply—including ICP-OES/ICP-MS plasma torches, laser ablation systems, X-ray diffractometers (XRD), FTIR spectrometers, HPLC column ovens, and electron microscopy cooling stages. Its stable flow and pressure profile support instruments with narrow hydraulic impedance tolerances. While not certified to specific regulatory standards (e.g., ISO 17025, FDA 21 CFR Part 11), the unit supports GLP/GMP-aligned workflows through traceable temperature logging (via optional RS485/Modbus interface), auditable parameter history, and configurable alarm thresholds for temperature deviation, low fluid level, or pump failure. Use of softened or deionized water is strongly recommended to prevent scaling and corrosion—consistent with ASTM D1193 Type II water specifications for laboratory applications.
Software & Data Management
The MC-1000C/BP features embedded firmware supporting local operation via front-panel keypad and LCD interface. For integration into automated lab environments, optional communication modules provide Modbus RTU over RS485, enabling remote monitoring and control via LIMS or SCADA platforms. Logged parameters—including setpoint, actual temperature, pump status, and runtime hours—are stored internally for ≥30 days and exportable via serial dump. No proprietary software installation is required; configuration and diagnostics are accessible through standard terminal emulation tools. Firmware updates are performed via USB port using signed binary files, ensuring integrity and version traceability.

- Temperature regulation in calorimetry cells and rheological test fixtures
- Support of long-duration, unattended operation in QC/QA laboratories adhering to ISO/IEC 17025 documentation requirements
FAQ
What type of coolant is recommended for optimal performance and longevity?
Deionized water (ASTM D1193 Type II) or softened water with ≤50 ppm total hardness is strongly recommended to inhibit scale formation and corrosion in the stainless-steel reservoir and pump head.
Can the MC-1000C/BP operate continuously for 24/7 applications?
Yes—the unit is rated for continuous duty (IEC 60034-1 S1 rating) with thermal overload protection, automatic restart after power interruption, and maintenance-free sealed bearings in the circulation pump.
Is external condenser water required for operation?
Yes—the “water-cooled” configuration requires a continuous supply of facility-supplied cooling water (typically 15–25 °C) to the condenser inlet, with return to a drain or recirculating system.
Does the chiller support external temperature feedback from the connected instrument?
No—the MC-1000C/BP operates in standalone mode using its internal PT100 sensor; it does not accept external process temperature signals for cascade control.
What safety protections are built into the system?
Over-temperature cutoff, low-level shutoff, pump dry-run prevention, compressor high-pressure lockout, and phase-loss detection for three-phase variants (if equipped).
