The Glunz & Jensen HDX 85/125/165 Thermal is a processor designed for daily use in a professional environment, as indicated by the "User's Guide" title and the emphasis on regular operation. The manual, published on February 12th, 2024, by Glunz & Jensen A/S, is provided in English (en-us) as the original version, with additional language support for German, French, Spanish, Italian, and Chinese, suggesting a broad international market for the device. The manual explicitly states the importance of keeping it with other equipment documentation for future reference, highlighting the need for users to consult it for safe and effective operation and maintenance.

Function Description:

The HDX 85/125/165 Thermal is a thermal processor, likely used in graphic arts or printing for processing plates or films. The manual uses various symbols to denote different functions and processes, providing a clear visual guide for users. Key operational stages include:

Developer (显影): This stage involves the application of developer solution. The symbol for "Developer" is a beaker with liquid, indicating a chemical process.
Wash (水洗): Following development, the material undergoes a washing stage. The "Wash" symbol shows water droplets, representing rinsing.
Gum (上胶): This stage involves gumming, likely to protect the processed material. The "Gum" symbol depicts a roller applying a coating.
Dryer (烘干): The final processing stage is drying. The "Dryer" symbol shows a fan, indicating air circulation for drying.
Waste (废物): The "Waste" symbol, a trash can, indicates the collection of waste products from the processing.

The device features both manual and automatic processes. The "Manual action" symbol (a hand pressing a button with "1") suggests user-initiated steps, while the "Automatic process" symbol (a gear with "A") indicates automated operations. This combination allows for flexibility in operation, catering to both routine automated tasks and specific manual interventions.

Important Technical Specifications:

While specific numerical specifications like dimensions, weight, or power consumption are not detailed in the provided pages, the manual does give important temperature ranges for certain operations. The "Temperature" symbol (a thermometer) is associated with a range of 35° - 60°C (95° - 140°F). This temperature range is crucial for the chemical processes involved, ensuring optimal performance and quality of the processed material. The presence of an "Alarm" symbol (a bell) suggests that the device is equipped with a system to alert users to critical conditions, potentially including temperature deviations or other operational issues.

Usage Features:

The manual emphasizes user safety and proper operation. It strongly advises users to always read the "Safety Instruction Manual part No. 21741" before starting the equipment and to keep all manuals with the equipment for reference. This highlights the importance of safety protocols and proper training for operators.

The device appears to have a user-friendly interface, likely a touchscreen, as suggested by the illustrations showing finger taps and menu navigation. The interface allows users to:

Power on/off: A rotary switch with "0 → 1" and "1 → 0" indicates a physical power control. The digital interface also shows a power icon, suggesting software-based power management or status display.
Access settings/modes: The gear icon on the digital interface likely leads to settings or different operational modes.
Monitor processes: The interface displays icons for developer, wash, gum, and dryer, allowing users to monitor the status of each stage.
Perform maintenance tasks: The interface includes options for "Developer fiber replaced," "Developer replaced," "Brush replaced," and "Cleaning tasks," indicating guided maintenance procedures.

The illustrations show the process of loading and unloading materials, as well as the placement of chemical containers. The device is designed to accommodate multiple chemical containers, suggesting a capacity for various processing solutions. The presence of a "Developer" symbol with a number "3" next to it, and another "Waste" symbol with a number "3", implies a system for managing chemical supply and waste disposal.

Maintenance Features:

Maintenance is a critical aspect of the HDX 85/125/165 Thermal, with dedicated sections and symbols for cleaning and maintenance. The manual provides specific recommendations for cleaning agents:

For major cleaning purposes: Citric acid 10% and Nitric acid 5%.
For cleaning off heavy algae-, fungal- or bacterial growth in the wash section: Commercially available biocide/strong alkalic liquid.

Crucially, the manual includes strong warnings regarding cleaning practices:

CAUTION: Never use hard tools or abrasive materials when cleaning any part of the processor.
WARNING: Never use cleaning agents containing chlorinated solvents or acetic or phosphoric acid, as these pose health hazards and can damage the processor.

The illustrations demonstrate several maintenance procedures:

Filter replacement: The manual shows how to open and close filters (indicated by "CLOSED" and "OPEN" labels with 180° rotations) and replace filter elements. This suggests a regular filter maintenance schedule.
Roller cleaning/maintenance: Illustrations show the removal and reinstallation of rollers, indicating that these components require periodic cleaning or replacement. The "Roller motor" option on the digital interface further supports the idea of specific maintenance for these parts.
Component removal for cleaning: Various parts of the processor can be opened or removed for cleaning, as shown in the detailed diagrams of the internal structure. This modular design facilitates thorough cleaning and access to internal components.
Waste management: The manual illustrates the process of replacing waste containers, emphasizing proper disposal of processing by-products.

Overall, the Glunz & Jensen HDX 85/125/165 Thermal is a sophisticated thermal processor designed for efficient and reliable operation, with a strong emphasis on user safety, clear operational guidance, and structured maintenance procedures to ensure longevity and optimal performance.
