HTCY LX-S10-BLP Integrated Circulating Chiller

Overview

The HTCY LX-S10-BLP is an integrated, air-cooled circulating chiller engineered for precision thermal management in laboratory and analytical instrumentation environments. It operates on a vapor-compression refrigeration cycle using R22 refrigerant and features a hermetic 0.5 HP compressor paired with a high-efficiency copper-aluminum finned condenser and branded axial fans for stable heat rejection under variable ambient conditions (up to 30°C). Designed for continuous-duty operation, the unit delivers a nominal refrigeration capacity of 1000 W at standard test conditions (30°C ambient, 22°C water outlet), maintaining setpoint temperature within ±0.2–0.3°C across its full operating range of 8–30°C. Its compact all-in-one architecture eliminates external piping complexity and integrates reservoir, pump, heat exchanger, and control logic into a single industrial-grade enclosure — optimized for space-constrained labs and benchtop integration with sensitive equipment requiring stable coolant supply.

Key Features

• Stainless steel reservoir (4.1 L volume) with corrosion-resistant PVC fluid path components and industrial-grade plastic centrifugal pump — ensuring long-term compatibility with deionized water and low-conductivity coolants.
• Digitally controlled dual-stage temperature regulation with 0.1°C display resolution and auto-memory function; one-touch power interface with intuitive LED status indicators.
• Integrated flow protection circuit that monitors real-time circulation rate and triggers shutdown if flow drops to ≤2 L/min — preventing dry-run damage and enabling safe interlock with host instruments.
• Dual-limit temperature safety system with independent high- and low-temperature alarms, configurable normally open/normally closed relay outputs for external process control or emergency shutdown signaling.
• Air-cooled condensing assembly featuring high-static-pressure, low-noise axial fans (rated for >30,000 hours MTBF) and optimized fin geometry for consistent performance across ambient temperatures from 15–35°C.
• Robust mechanical construction: powder-coated steel chassis, vibration-damped compressor mounting, and IP20-rated electrical compartment compliant with IEC 61000-6-3 EMC standards.

Sample Compatibility & Compliance

The LX-S10-BLP is compatible with a wide range of laboratory instruments requiring regulated coolant delivery, including graphite furnace atomic absorption spectrometers (GFAAS), rotary evaporators, vacuum diffusion pumps, turbomolecular pumps, glovebox purge systems, and laser cooling loops. Its stainless steel reservoir and non-metallic wetted materials meet general requirements for low-ion leaching in analytical applications. While not certified to specific ISO/IEC 17025 calibration standards as a metrological instrument, the chiller’s temperature stability (±0.2–0.3°C) and repeatability support GLP-compliant experimental protocols where thermal consistency is critical. The unit conforms to GB 4706.1–2005 (Chinese national safety standard for household and similar electrical appliances) and meets CE marking requirements for electromagnetic compatibility (EN 61000-6-3) and low-voltage directive (2014/35/EU).

Software & Data Management

The LX-S10-BLP operates via embedded microcontroller firmware with no external software dependency. All operational parameters — setpoint temperature, actual water temperature, pump status, fault codes (e.g., “E1: Low Flow”, “E2: High Temp”), and runtime hours — are accessible through the front-panel LED interface. Relay outputs (NO/NC) provide analog-compatible TTL-level signals for integration into building management systems (BMS) or SCADA networks via optional signal conditioners. For audit-trail compliance in regulated environments, users may log operational events manually or via external data loggers connected to the alarm output terminals. The device does not incorporate FDA 21 CFR Part 11–compliant electronic records functionality, as it lacks user authentication, electronic signatures, or encrypted data storage — consistent with its classification as auxiliary infrastructure rather than a GMP-critical analytical instrument.

Applications

• Cooling of graphite furnace atomizers in AAS systems, where precise thermal gradient control prevents matrix interference and improves detection limits.
• Thermal stabilization of rotary evaporator condensers to maximize solvent recovery efficiency and prevent vapor breakthrough during high-boiling-point solvent removal.
• Heat dissipation for high-vacuum turbomolecular and diffusion pumps, maintaining bearing and stator temperatures within manufacturer-specified limits during extended pump-down cycles.
• Temperature-controlled purge gas conditioning in inert-atmosphere gloveboxes, reducing moisture ingress by pre-cooling nitrogen or argon streams prior to entry.
• Secondary cooling loop support for laser sources, CCD detectors, and RF generators where stable junction temperatures directly impact signal-to-noise ratio and component longevity.

FAQ

What is the minimum recommended coolant conductivity for use with the LX-S10-BLP?
Deionized water with conductivity below 5 µS/cm is recommended; addition of 10–15% ethylene glycol is permissible for sub-zero ambient installations, though viscosity effects on pump head must be validated.
Can the unit be operated in a ventilated fume hood?
No — the air-cooled condenser requires unrestricted ambient airflow; operation inside enclosed spaces will cause high-head pressure trips and premature compressor failure.
Is remote monitoring possible via RS485 or Ethernet?
Not natively; the LX-S10-BLP lacks digital communication ports. Modbus RTU integration requires third-party protocol converters interfaced with the relay and analog output terminals.
Does the chiller include a built-in water level sensor?
Yes — a float-type level switch provides low-reservoir shutdown and visual warning on the display panel.
What maintenance intervals are specified for routine service?
Compressor oil and refrigerant charge require inspection every 24 months under continuous operation; condenser fins should be cleaned quarterly in dusty environments using compressed air or soft brush.
