Overview

  1. Function Description
  2. Important Technical Specifications
  3. Usage Features
  4. Maintenance Features

The HRLE Series Thermo-chiller is a compact dual/basic type circulating fluid temperature controller designed for laser applications, offering both air-cooled and water-cooled refrigeration options. It is engineered for precise temperature control, space saving, and energy efficiency, with a newly added 5 kW cooling capacity specification (HRLE050).

Function Description:

The HRLE Series controls the temperature of two independent fluid channels (CH1: Oscillator and CH2: Optical system) using a single compressor, pump, and tank. This dual-channel control is achieved through a sophisticated refrigeration circuit that utilizes expansion valves A, B, and C to either cool or heat the circulating fluid. For heating, the system can circulate hot discharged gas from the refrigerant, eliminating the need for a separate heater and contributing to energy savings. The system also features a facility water circuit for water-cooled models, which regulates refrigerant gas pressure and flow rate.

Important Technical Specifications:

  • Cooling Capacity: Available in various capacities, including 5 kW (HRLE050) and 8.0/9.5 kW (HRLE090) for air-cooled, and 9.5/11.0 kW for water-cooled models (total CH1, 2).
  • Temperature Stability: Achieves high precision with ±0.1°C for CH1 and ±0.5°C for CH2 when the load is stable.
  • Set Temperature Range: CH1: 15 to 25°C; CH2: CH1 + 0 to 15°C.
  • Refrigerant: Uses R410A (HFC).
  • Power Supply: Globally compatible with 3-phase 200 VAC, 200 to 230 VAC, 380 to 415 VAC, 460 to 480 VAC, and single-phase 200 to 230 VAC (50/60 Hz).
  • Fluid Contact Materials: Stainless steel, Copper (Heat exchanger brazing), Bronze (Pump), Ceramic, Carbon, FKM, PP, PE, POM, PVC, PA, EPDM. For deionized water (pure water) piping option, non-copper materials are used.
  • Dimensions (HRLE090): Height 1055 mm, Width 445 mm, Depth 965 mm.
  • Footprint Reduction: Reduced by 21% compared to two separate units.
  • Power Consumption: Reduced by 17% due to the single compressor, fan, and pump design, and heaterless heating function.
  • Communication: Equipped with serial communication (RS485) and contact I/Os (2 inputs, 3 outputs) as standard.
  • Protection: Electrical box rated IPX4.

Usage Features:

  • Simple Operation: Features a large digital display (7-segment, 4 digits) for clear viewing of current and set values. Temperature settings are easily adjusted with up/down keys.
  • Space Saving: Compact design allows for individual temperature control of two channels within a single unit, reducing installation footprint.
  • Reduced Wiring/Labor: Requires only one power supply system for two channels, simplifying wiring and reducing installation time.
  • Heaterless Heating: Utilizes hot discharged gas from the refrigerant for heating, eliminating the need for a separate heater and saving energy.
  • Globally Compatible Power Supplies: Designed to operate with various global power supply voltages without requiring step-down transformers.
  • Easy Fluid Supply: Angled supply port facilitates easy filling of circulating fluid.
  • Easy Tank Cleaning: Features a separate opening with a cap (Ø110 mm) behind the water inlet for convenient cleaning.
  • Toolless Inspection/Cleaning: Air-cooled condenser includes a dustproof filter that can be removed without tools for easy cleaning of dust and chips.
  • 24 VDC Power Supply: Available from the terminal block for external switches.
  • Increased Cooling Capacity Function (Option): Inverter for compressor increases cooling capacity in 50 Hz regions to match 60 Hz performance.
  • Deionized Water (Pure Water) Piping (Option): Ensures contact materials are non-copper for compatibility with deionized water.
  • Inverter for Pump (Option): Increases pump capacity and allows for auto control of pressure without valve adjustments.
  • Electric Conductivity Control Set (Option): Allows arbitrary setting of circulating fluid electric conductivity (0.5 to 45.0 µS/cm).
  • Particle Filter Set (Option): Removes foreign matter from the circulating fluid, preventing pump malfunction and maintaining condenser performance.
  • Anti-freezing Operation Function: Automatically operates the pump to warm circulating fluid if it approaches freezing point.
  • Key-lock Function: Protects set values from accidental changes.
  • Self-diagnosis Function: Displays alarm codes for easy identification of errors.

Maintenance Features:

  • Check Display: Provides internal temperature, pressure, and operating time information.
  • Periodical Inspection (Monthly): Clean the ventilation grille to prevent clogging and maintain cooling performance. Use a long-haired brush or air gun for cleaning.
  • Periodical Inspection (Every Three Months):
    • Inspect circulating fluid: Replace regularly to prevent bacteria or algae growth.
    • Tank cleaning: Check for dirt, slime, or foreign matter and clean the tank regularly.
    • Ethylene glycol aqueous solution: Use a concentration meter to confirm concentration does not exceed 15% and adjust as needed.
  • Periodical Inspection (Winter Season): Make water-removal arrangements beforehand if there is a risk of freezing. Consult a professional for additional anti-freezing functions if needed.
  • Operation Manual: Thoroughly read the operation manual for complete understanding of operation and maintenance procedures.
