Overview
The Sperate SC-800 Integrated Circulating Chiller is an engineered thermal management solution designed for stable, continuous temperature control in laboratory and analytical instrument applications. It operates on a closed-loop refrigeration principle, combining compressor-based cooling with resistive heating to maintain precise setpoint temperatures across a broad operational range (10–60 °C). Unlike ambient-air-cooled chillers, the SC-800 employs a water-cooled condenser system—enabling consistent thermal performance in environments where ambient air temperature or humidity may fluctuate significantly. Its integrated architecture eliminates external heat exchanger dependencies, reducing footprint and installation complexity while supporting reliable operation alongside sensitive equipment such as spectrophotometers, laser systems, ICP-OES/MS accessories, and rotary evaporators. The unit is constructed for long-term duty cycles and engineered for precision under variable load conditions typical of multi-instrument lab networks.
Key Features
- Integrated dual-mode thermal regulation: Simultaneous active cooling and heating via hermetically sealed refrigeration circuit and PID-controlled immersion heater.
- Stable temperature output with ±2 °C uniformity across full flow range (0–3 L/min), verified per ISO 17025 traceable calibration protocols.
- Self-contained 5 L stainless-steel reservoir with level sensor and anti-corrosion coating compatible with deionized water and common glycol/water mixtures (up to 30% v/v).
- High-efficiency circulation pump delivering up to 3 L/min at 0.3 MPa pressure—sufficient to overcome typical backpressure from coiled tubing, heat exchangers, or inline filters.
- Multi-mode control interface: Local keypad operation, analog 0–10 V / 4–20 mA input for external device synchronization, and RS485 Modbus RTU protocol for integration into centralized lab automation systems.
- Thermal safety architecture including dry-run protection, overtemperature cutoff, high-pressure shutdown, and reservoir low-level alarm with relay output.
Sample Compatibility & Compliance
The SC-800 is compatible with standard laboratory coolant media—including purified water, ASTM D1193 Type II water, and aqueous ethylene glycol solutions (≤30%). It meets GB/T 20159.3–2018 (Chinese national standard for laboratory chillers) and conforms to electromagnetic compatibility requirements per GB 4824–2019 (CISPR 11 Class B). While not certified to UL/CSA or CE for direct EU/NA market placement, its electrical design adheres to IEC 61010-1:2010 safety principles for laboratory equipment. For GLP/GMP-regulated environments, optional audit-trail-enabled firmware supports time-stamped event logging (power cycles, setpoint changes, fault triggers) compliant with FDA 21 CFR Part 11 data integrity expectations when deployed with validated software infrastructure.
Software & Data Management
The SC-800 does not include proprietary cloud software but provides deterministic, low-latency serial communication (Modbus RTU over RS485) for seamless integration with third-party SCADA platforms (e.g., LabVIEW, Ignition, WinCC) or LIMS middleware. All operational parameters—including real-time temperature, flow rate, compressor status, and error codes—are accessible via register mapping. Optional OEM firmware upgrades support configurable alarm thresholds, ramp-rate limiting, and scheduled power-on/off sequences. Data export is achieved through host-system polling; no internal storage or web interface is implemented—ensuring deterministic response times and eliminating cybersecurity attack surfaces associated with embedded OS environments.
Applications
- Temperature stabilization of optical components in UV-Vis, FTIR, and Raman spectrometers.
- Cooling of high-power LED light sources and photomultiplier tube housings requiring thermal drift mitigation.
- Heat removal from vacuum pump motor casings and cold traps in rotary evaporation systems.
- Process cooling for small-scale chemical reactors and electrochemical cells operating below ambient.
- Supporting constant-temperature operation of HPLC column ovens and autosampler cooling modules.
- Calibration reference baths for thermocouple and RTD verification within metrology labs.
FAQ
What is the maximum allowable coolant viscosity for stable operation?
The SC-800 is rated for fluids with dynamic viscosity ≤5 mPa·s at 20 °C. Glycol concentrations exceeding 30% v/v may impair flow stability and reduce effective cooling capacity.
Can the unit operate continuously at 10 °C ambient temperature?
Yes—the water-cooled condenser design enables uninterrupted operation down to 5 °C ambient, provided the facility cooling water supply remains within 5–30 °C and ≥2 bar pressure.
Is remote monitoring possible without additional hardware?
Remote readout requires an RS485-to-Ethernet gateway or PLC with Modbus master capability. No built-in Wi-Fi or Ethernet port is included.
Does the chiller support external temperature feedback control?
Yes—via analog voltage or current input (0–10 V / 4–20 mA), enabling cascade control using a downstream process sensor.
What maintenance intervals are recommended for extended service life?
Compressor oil inspection every 24 months; condenser water filter cleaning every 3 months; reservoir descaling every 6 months when using non-deionized water.
