EYELA CA-1310 Circulating Chiller

Overview

The EYELA CA-1310 Circulating Chiller is a compact, air-cooled refrigeration system engineered for precise thermal management in laboratory environments where space efficiency and reliable cooling performance are critical. Designed using closed-loop circulation architecture, it maintains stable bath temperatures between −20°C and +20°C—ideal for supporting heat-sensitive processes such as rotary evaporation, condenser jacketing, reaction vessel cooling, and chromatography column temperature control. Its core thermodynamic operation relies on a hermetic compressor system utilizing R407C refrigerant, coupled with a copper-nickel plated cooling coil and SUS304 stainless steel reservoir to ensure corrosion resistance and long-term fluid integrity. The unit’s vertical footprint (570 mm height) allows installation beneath standard laboratory workbenches, eliminating the need for dedicated floor space while maintaining full operational accessibility via its hinged front-panel interface.

Key Features

• Space-optimized design: 570 mm total height enables under-bench placement without compromising service access or thermal performance.
• Hinged front control panel: Flip-up digital interface provides intuitive temperature setting and real-time monitoring without requiring overhead reach or cabinet door removal.
• Integrated level indicator: Transparent sight gauge permits visual verification of coolant volume and flow status without opening the reservoir lid—enhancing safety and procedural continuity.
• Robust safety architecture: Equipped with dual-stage overtemperature protection, compressor overload cutoff, high-pressure switch, ground-fault circuit interrupter (GFCI), pump thermal cutout, and self-diagnostic thermostat functionality.
• Precision temperature control: Touch-key digital input with 0.1°C resolution and ±2°C stability across the full operating range; ON-OFF compressor modulation ensures energy-efficient load matching.
• High-flow external circulation: Capable of delivering up to 16 L/min at 9.5 m head pressure, supporting simultaneous cooling of multiple instruments—including two rotary evaporators under typical lab conditions.

Sample Compatibility & Compliance

The CA-1310 is compatible with water-based and water-glycol coolant mixtures (up to 30% v/v ethylene glycol). Its SUS304 tank and nickel-plated copper cooling coils resist degradation from common laboratory coolants, ensuring consistent thermal transfer and minimal maintenance over extended duty cycles. While not certified for hazardous location use, the unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets JIS C 61010-1 standards for Japanese market conformity. It supports GLP-compliant workflows through stable setpoint retention and traceable temperature logging when integrated with external data acquisition systems.

Software & Data Management

The CA-1310 operates as a standalone analog-controlled chiller with no embedded firmware or network interface. Temperature settings and operational status are managed exclusively via its local touch-key display and LED indicators. For laboratories requiring audit-ready records, the unit can be interfaced with third-party data loggers via optional analog voltage output modules (sold separately) or connected to centralized building management systems using standard 4–20 mA or 0–10 V signal inputs. All safety events—including compressor shutdowns, overtemperature alerts, and flow interruption—are indicated visually on the front panel and retained in non-volatile memory for post-event diagnostics.

Applications

• Cooling jackets of rotary evaporators (supports dual-unit operation at 10°C bath temperature)
• Temperature stabilization of analytical instrumentation including HPLC, GC, and UV-Vis spectrophotometers
• Condenser cooling in distillation and extraction setups
• Controlled-temperature reaction baths for synthetic chemistry and polymerization studies
• Support for cryogenic sample preparation stages in materials science labs
• Backup cooling for laser sources and optical alignment stations requiring low-noise thermal regulation

FAQ

What is the maximum recommended coolant mixture ratio for the CA-1310?

The unit is validated for aqueous solutions containing up to 30% (v/v) ethylene glycol. Higher concentrations may impair heat transfer efficiency and increase viscosity beyond the pump’s operational envelope.
Can the CA-1310 operate continuously at −20°C ambient temperature?

No. As an air-cooled chiller, it requires ambient conditions between +5°C and +35°C per JIS B 8606 specifications. Operation below +5°C ambient may cause refrigerant pressure instability and compressor lubrication issues.
Is remote monitoring or Ethernet connectivity supported natively?

No. The CA-1310 lacks built-in communication ports. Integration with SCADA or LIMS requires external analog signal converters and programmable logic controllers.
What maintenance intervals are recommended for optimal performance?

Filter cleaning every 3 months; refrigerant charge verification and compressor oil inspection annually by authorized EYELA service technicians.
Does the unit meet FDA 21 CFR Part 11 requirements for electronic records?

Not independently. Compliance depends on how the device is integrated into a validated system—e.g., when paired with 21 CFR Part 11–compliant data loggers and electronic signature workflows.
