HTCY LX-M15-THP Integrated High-Capacity Air-Cooled Circulating Chiller

Overview

The HTCY LX-M15-THP is an integrated, air-cooled circulating chiller engineered for continuous, high-capacity thermal management in demanding laboratory and industrial environments. Designed to deliver stable, controllable coolant flow across extended operational cycles, it replaces reliance on municipal water supply—eliminating temperature fluctuations, pressure inconsistencies, and excessive water consumption. Its core thermodynamic architecture employs a vapor-compression refrigeration cycle using R22 refrigerant, coupled with a high-efficiency scroll compressor and stainless-steel or plate-type heat exchangers. The system maintains precise temperature setpoints within an operational range of 8–30 °C, with stability of ±2 °C under nominal conditions (30 °C ambient, 22 °C outlet). With a rated refrigeration capacity of 15,000 W and a maximum flow rate of 117 L/min at up to 4.6 bar pressure, the LX-M15-THP supports large-scale instrumentation—including NMR spectrometers, ICP-MS systems, laser sources, X-ray diffractometers, and high-power electrophoresis or chromatography modules—where consistent heat extraction and hydraulic reliability are critical to measurement integrity and equipment longevity.

Key Features

• Compact vertical chassis design (590 × 1405 × 1365 mm) minimizes floor space requirements while enabling top-mounted airflow discharge—facilitating integration with ducted ventilation or room exhaust systems.
• High-reliability scroll compressor from internationally certified manufacturers, delivering robust performance, low mechanical vibration, and acoustic output limited to 64 dBA at 1 m distance.
• Optimized air-cooled condenser featuring V-shaped finned coil geometry and EBMPAPST or Ziehl-Abegg axial fans—engineered for uniform airflow distribution, enhanced heat transfer coefficient, and resistance to environmental dust ingress.
• Digital microprocessor-based temperature controller with one-touch operation, programmable setpoint memory, real-time temperature display (inlet/outlet), and dual-mode relay outputs (NO/NC) for external interlock or alarm signaling.
• Stainless-steel multi-stage centrifugal circulation pump (750 W, 20–46 m head), paired with 110 L corrosion-resistant reservoir and DN25 stainless inlet/outlet ports—ensuring long-term compatibility with deionized, glycol-blended, or inhibited aqueous coolants.
• Comprehensive safety architecture including flow monitoring (switch actuation: >10 L/min ON / <8 L/min OFF), level sensing, over-temperature cut-off, and motor overload protection—all compliant with IEC 61000-6-2/6-4 electromagnetic immunity standards.

Sample Compatibility & Compliance

The LX-M15-THP is designed for use with non-corrosive, non-viscous aqueous or water-glycol mixtures (up to 30% v/v ethylene or propylene glycol). It is not intended for direct contact with organic solvents, acids, or caustic solutions. All wetted components—including reservoir, pump housing, heat exchanger surfaces, and piping interfaces—are constructed from AISI 304 stainless steel or food-grade PVC-rated industrial tubing, ensuring resistance to oxidation and leaching under continuous recirculation. While not certified to UL/CSA for North American electrical safety, the unit conforms to GB/T 10870–2014 (Chinese national standard for liquid chillers) and meets CE marking requirements per Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. Its control logic supports integration into GLP-compliant workflows via configurable analog (0–10 V / 4–20 mA) and digital (RS485 Modbus RTU) interfaces for centralized monitoring and audit-trail logging.

Software & Data Management

The LX-M15-THP operates autonomously via its embedded digital controller and does not require proprietary PC software for basic function. However, optional RS485 Modbus RTU communication enables seamless integration with laboratory information management systems (LIMS), building automation platforms (BAS), or SCADA environments. Users may configure remote setpoint adjustment, real-time temperature/flow telemetry, fault event logging (with timestamp and error code), and scheduled start/stop sequences. All data exchanges adhere to Modbus register mapping defined in HTCY’s technical annex, supporting traceability in regulated settings where electronic records must satisfy FDA 21 CFR Part 11 requirements when deployed alongside validated host software.

Applications

• Thermal stabilization of high-field superconducting magnets in NMR and MRI preclinical systems
• Coolant supply for plasma-based analytical instruments (ICP-OES, ICP-MS) requiring stable torch and detector temperatures
• Heat dissipation for high-power CO₂ and fiber lasers used in materials processing and spectroscopy
• Temperature-controlled recirculation in rotary evaporation, molecular distillation, and reaction calorimetry setups
• Support cooling loop for X-ray generators, electron beam welders, and RF amplifiers in physics laboratories
• Backup chilled-water source for HVAC-integrated cleanroom or controlled-environment test chambers

FAQ

What is the minimum allowable coolant temperature for continuous operation?
The system is rated for stable operation down to 8 °C. Sustained use below this threshold risks evaporator freeze-up and is not recommended without antifreeze admixture and recalibration of low-temperature safety limits.
Can the chiller be operated in ambient temperatures exceeding 30 °C?
Performance degrades above 30 °C ambient; refrigeration capacity falls approximately 1.2% per °C rise. Operation above 35 °C ambient requires derating verification and may trigger thermal shutdown if condenser airflow is restricted.
Is the unit suitable for use with deionized water only?
Yes—provided conductivity remains >1 µS/cm to ensure proper flow switch actuation. For long-term DI water use, periodic biocide dosing or UV sterilization integration is advised to prevent biofilm formation in the reservoir and pump.
Does the LX-M15-THP support external temperature feedback control?
Yes—the controller accepts a 0–10 V analog input from an external PT100 or thermistor sensor mounted at the process load, enabling cascade control mode for improved thermal response fidelity.
What maintenance intervals are recommended for optimal service life?
Compressor oil and refrigerant charge should be verified annually; condenser fins require quarterly cleaning; pump seals and flow switch calibration are recommended every 18 months under continuous duty.
