Guide for Building Chemical Low-Temperature Cooling Systems, Corrosion-resistant Industrial Refrigeration Unit Matching Scheme

The production processes of fine chemicals, new materials, and daily chemicals require a stable low-temperature cooling environment. The corrosive gases and high humidity and high-temperature conditions in the workshop have extremely high requirements for the protection level of refrigeration equipment. Ordinary commercial cold storage units will experience pipe rusting, refrigerant leakage, and shutdown failures after short-term use, directly interrupting the production line operation. This article summarizes the complete scheme for building chemical cooling systems and the selection standards for units.
1. Classification of Corrosive Conditions in Chemical Workshops
Mild corrosion: Ordinary daily chemical auxiliary materials processing, with slight water vapor evaporation, equipment foundation can be protected by simple anti-corrosion spraying; Moderate corrosion: Acid and alkali raw material processing, volatile corrosive gases, copper pipes and sheet metal need to be thickened with anti-corrosion coatings; Severe corrosion: Chemical synthesis and reagent production, high-concentration corrosive media, the entire machine pipeline needs to be thickened, and the entire sealing and anti-corrosion structure needs to be upgraded.
Before purchasing, determine the corrosion level of the workshop first, and then match the corresponding protection configuration. Do not uniformly select basic standard models.
2. Three Core Upgraded Configurations of Corrosion-resistant Industrial Units
Heat exchange system upgrade: Select thickened copper tubes, spray special anti-corrosion coating on fins, isolate corrosive gases from direct contact with metal;
Sheet metal enclosure upgrade: Double-layer anti-rust and anti-corrosion spraying, add sealing sleeves to pipe joints, reduce water vapor infiltration;
Electrical control system upgrade: Fully sealed dust-proof and anti-corrosion electrical control box, increase anti-corrosion insulation sleeves for lines, avoid circuit short circuits.
For 24-hour uninterrupted production lines, compressors should select heavy-duty and high-temperature-resistant models to cope with the continuous high-temperature environment in the workshop.
3. Key Design Points for Chemical Cooling System Accessories
Keep the equipment installation area well-ventilated to reduce the concentration of corrosive gases in the workshop; Simplify the pipe layout to reduce welding joints and reduce leakage risks; Equip with independent filtration devices to prevent chemical dust from adhering to the heat exchanger; Reserve a backup unit switching interface to ensure continuous cooling of the production line when the main equipment fails.
4. Advantages of Customized Chemical Factory Customization for Chemical Cooling Systems
Shaoxing Xueying Refrigeration can customize industrial low-temperature cooling units according to the customer's workshop corrosion level, production load, and local power supply standards. Complete thickening of copper tubes, multi-layer anti-corrosion, and sealing electrical control upgrades can be carried out. The entire machine undergoes long-term load testing in simulated high-temperature corrosive environment before leaving the factory. It is suitable for domestic chemical parks and overseas chemical production bases and can provide a complete set of cooling system scheme design, equipment production, remote debugging guidance one-stop service.
5. Regular Corrosion Maintenance Plan for Chemical Refrigeration Equipment
Clean the corrosion deposits on the heat exchanger surface quarterly, check the damaged positions of the coating and timely reapply; Conduct a comprehensive inspection of the pipe air tightness every year, check for trace refrigerant leakage; Regularly replace the fan and electrical control sealing rubber rings to delay component aging; Regularly turn on the ventilation equipment in the workshop to reduce the concentration of corrosive gases. Summary
In the chemical industry's low-temperature cooling scenarios, it is necessary to match industrial refrigeration units with graded anti-corrosion upgrades. Combined with the ventilation of the workshop and the installation of backup units, a complete cooling system should be constructed. Selecting source factories with the ability to customize industrial equipment non-standardly and detect various corrosive conditions can ensure the long-term stable low-temperature operation of the chemical production line and reduce downtime losses.
