HTCY FT-M13-THP Split-Type Circulating Chiller

Overview

The HTCY FT-M13-THP Split-Type Circulating Chiller is an engineered thermal management solution designed for laboratory and industrial applications requiring precise, stable, and continuous cooling of analytical instruments, laser systems, reactors, and other heat-sensitive equipment. Unlike monoblock chillers, its split architecture separates the refrigeration unit (outdoor condensing section) from the water circulation module (indoor evaporator/reservoir assembly), significantly reducing operational noise in sensitive lab environments while improving heat rejection efficiency. The system operates on a vapor-compression refrigeration cycle using R410A or equivalent environmentally compliant refrigerant, delivering consistent cooling performance across ambient temperatures up to 40 °C. Its core function is to maintain process fluid—typically deionized water or water-glycol mixtures—at a user-defined setpoint within the 8–30 °C range, with temperature stability held to ±1 °C under dynamic load conditions. This level of thermal control supports reproducible experimental outcomes and protects capital-intensive instrumentation from thermal drift and overheating.

Key Features

• Split-system configuration minimizes indoor acoustic emissions (<62 dB(A) at 1 m from indoor unit), ideal for ISO Class 5–7 cleanrooms and quiet laboratory zones.
• Microprocessor-based PID temperature controller with real-time digital display of setpoint and actual reservoir temperature (0.1 °C resolution).
• High-efficiency centrifugal circulation pump offering adjustable flow rates from 8 to 58 L/min and pressure output ranging from 2.5 to 5.4 bar—compatible with long-loop piping and multi-instrument manifolds.
• 230 L insulated stainless-steel reservoir with level sensor, anti-corrosion coating, and integrated air venting to prevent cavitation and ensure bubble-free flow.
• Comprehensive safety architecture including high/low pressure cutouts, overtemperature protection, low-flow alarm, dry-run prevention, and compressor phase-loss monitoring.
• Modular design enables field serviceability; refrigerant circuit and electrical compartments are fully segregated per IEC 61000-6-2 EMC requirements.

Sample Compatibility & Compliance

The FT-M13-THP is compatible with standard laboratory coolants including deionized water (resistivity ≥1 MΩ·cm), 20–30% ethylene glycol/water mixtures, and inhibited aqueous solutions meeting ASTM D1384 corrosion standards. It meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. Electrical insulation conforms to IEC 61000-4-5 surge immunity (2 kV line-to-earth). While not certified for hazardous locations, its IP24-rated indoor unit and IP54 outdoor condenser comply with EN 60529 for indoor and semi-outdoor installation. The system supports GLP/GMP-aligned operation through configurable event logging and optional analog 4–20 mA output for integration into central building management systems (BMS).

Software & Data Management

The chiller includes embedded firmware supporting RS485 Modbus RTU communication (standard) and optional Ethernet TCP/IP interface for remote monitoring via SCADA or LabVIEW-compatible platforms. Logged parameters include real-time temperature, flow rate, compressor run time, fault codes, and cumulative energy consumption (kWh). Audit trail functionality records all parameter changes and alarm events with timestamps, satisfying basic FDA 21 CFR Part 11 data integrity expectations when paired with validated third-party data acquisition software. No proprietary cloud platform is required; raw Modbus register maps are supplied for custom integration.

Applications

• Cooling high-power UV-Vis spectrophotometers, ICP-OES/MS plasma sources, and X-ray diffraction (XRD) tube assemblies where thermal lensing must be minimized.
• Thermal stabilization of HPLC column ovens, GC injectors, and mass spectrometer ion sources demanding sub-±1 °C bath uniformity.
• Supporting continuous-operation processes such as rotary evaporation, jacketed reactor temperature control, and laser material processing systems.
• Providing chilled water to HVAC secondary loops in pilot-scale bioreactor suites where precise coolant supply temperature affects culture viability.
• Backup cooling for redundant instrument clusters in pharmaceutical QC labs operating under Annex 1 and USP analytical instrument qualification protocols.

FAQ

What is the maximum allowable ambient temperature for outdoor unit operation?
The outdoor condensing unit is rated for continuous operation at ambient temperatures up to 43 °C, with derated capacity above 35 °C per AHRI 550/590 standards.
Can this chiller be integrated into a facility-wide BMS?
Yes—via standard Modbus RTU over RS485 or optional Ethernet TCP/IP, enabling read/write access to setpoints, status bits, and alarm registers.
Is the reservoir compatible with 30% propylene glycol solutions?
Yes; all wetted parts—including pump housing, heat exchanger, and tank liner—are constructed from 304 stainless steel and EPDM elastomers, resistant to glycol-based coolants per ASTM D1384 Class III requirements.
Does the system support 24/7 unattended operation?
Yes; designed for continuous duty with automatic restart after power interruption and built-in safeguards against freeze-up, overflow, and low-flow conditions.
What maintenance intervals are recommended?
Compressor oil and refrigerant circuit inspection every 24 months; annual cleaning of outdoor coil fins and replacement of inlet water filter cartridge (optional accessory).
