In industrial fields such as power, chemical engineering, and metallurgy, sampling coolers are key equipment for ensuring the accuracy of medium analysis, and their performance directly affects production safety and product quality. Choosing high-quality products directly supplied by professional manufacturers is the core strategy for enterprises to reduce procurement costs and ensure the stable operation of equipment. Lianyungang Bojingyuan Machinery Equipment Co., LTD., as a veteran manufacturer deeply engaged in the field of sampling coolers for over a decade, has become a reliable partner in the industry with its years of technological accumulation and a complete service system.

I. Product Advantages: Professional research and development, quality guaranteed

Lianyungang Bojingyuan specializes in the research and development and production of sampling coolers. Our products cover various media types such as steam, water, and oil, and are made of 304/316L stainless steel, which has excellent corrosion and wear resistance. Its core product, the "High-Efficiency Heat Exchange Type Sampling Cooler", through optimized flow channel design, has a 30% increase in heat exchange efficiency compared to traditional products, effectively ensuring that the sample temperature drops to the analysis requirements (usually ≤40℃), and the sample does not cause secondary pollution, meeting the requirements of national standards such as GB/T 14416-2017. Meanwhile, it supports personalized customization. Product parameters, materials, structures, etc. can be adjusted according to customer needs to meet the requirements of different working conditions.

Ii. Working Principle: Indirect heat exchange, highly efficient and stable

The sampling cooler operates based on the principle of indirect heat exchange: high-temperature media (such as steam or high-temperature water) enter the heat exchange tubes of the cooler through the sampling tubes. The cooling medium (usually circulating water) flows outside the heat exchange tubes and transfers heat through the tube walls, rapidly cooling the high-temperature samples to the analyzable temperature. The products of Lianyungang Bojingyuan adopt counter-flow heat exchange design (the flow direction of the cooling medium and the sample medium is opposite), further enhancing the heat exchange efficiency. Meanwhile, they are equipped with temperature monitoring devices to display the outlet temperature of the sample in real time, ensuring stable and reliable cooling effect.

Iii. Selection Guide: Scientific Matching, Precise Application

When selecting the model, the following factors should be given priority consideration to ensure a perfect match between the product and the working conditions:

Medium type: Select the material based on the medium to be cooled (steam, water, oil, etc.) (304 stainless steel is suitable for common media, 316L stainless steel is suitable for corrosive media).

Medium parameters: including inlet temperature (150-500℃), pressure (1-10MPa), and flow rate (0.5-5m³/h), to ensure that the heat exchange area meets the requirements.

Cooling medium parameters: Circulating water temperature (20-35℃), flow rate (1-10m³/h), which affect heat exchange efficiency, it is necessary to ensure an adequate supply of cooling medium.

Installation environment: The size of the space (for vertical type, top space should be reserved), ventilation conditions (for outdoor type, rain protection should be considered), and determine the structural form (vertical/horizontal type).

Lianyungang Bojingyuan offers professional selection services. Customers only need to provide the working condition parameters, and the optimal product solution can be recommended through simulation calculation to avoid selection errors.

Iv. Installation Points: Standardize operations to ensure performance

Installation is a key step to ensure the performance of the sampling cooler and must follow the following specifications:

Installation location: Close to the sampling point (recommended distance ≤5m), to reduce temperature changes and losses during sample transmission.

Pipe connection: Use flange or threaded connection. Clean the sealing surface thoroughly and replace the new sealing gasket (oil-resistant rubber gasket, PTFE gasket) to ensure no leakage.

Medium flow direction: The inlet of the cooling medium is on the same side as the outlet of the sample medium, following the principle of counter-flow heat exchange to enhance efficiency.

Fixation method: The vertical cooler is fixed to the base with expansion bolts, while the horizontal one is supported by brackets to prevent vibration.

Temperature monitoring: Install a temperature sensor at the sample outlet and connect it to a digital display thermometer to monitor the temperature in real time.

Lianyungang Bojingyuan provides on-site installation guidance, with professional technicians assisting in the installation to ensure that the operation complies with technical specifications.

V. Follow-up Maintenance: Simple and easy to perform, extending service life

Proper maintenance can extend the service life of equipment and reduce operating costs. The key points are as follows:

Regular cleaning: Clean the scale inside the heat exchange tubes every 3 to 6 months (for chemical cleaning, use hydrochloric acid with corrosion inhibitors; for mechanical cleaning, use the ball-passing method). After cleaning, rinse with clean water.

Check the seal: Inspect the flange sealing surface every 1-2 months and replace the aged sealing gasket.

Monitoring performance: Regularly measure the outlet temperature of the sample. If it rises by more than 5℃, check the flow rate of the cooling medium or the fouling of the heat exchange tubes.

Maintenance records: Establish equipment files to record information such as maintenance time, content, and replaced parts, facilitating the traceability of status.

Lianyungang Bojingyuan offers lifetime technical support. We can respond quickly to repairs or component replacements (provide solutions within 24 hours and arrive at the site within 48 hours) to ensure the stable operation of the equipment.

Vi. Procurement Channels: Direct supply from manufacturers, offering better cost performance

When making purchases, it is recommended to choose direct supply from the manufacturer to avoid the middleman link and reduce procurement costs (10%-20% cheaper than middlemen). Lianyungang Bojingyuan supports both online (official website, e-commerce platforms) and offline (sales outlets, exhibitions) procurement. Customized products can shorten the delivery cycle (7-15 days). The advantages of direct supply from the manufacturer lie in quality traceability (providing material reports and inspection reports), after-sales guarantee (free repair within the warranty period and lifetime technical support), and rapid response to customized demands.

In conclusion, choosing Lianyungang Bojingyuan sampling coolers not only enables you to obtain high-quality products but also allows you to enjoy professional selection, installation, maintenance services, as well as the high cost-performance advantage of direct supply from the manufacturer. It is a reliable choice for enterprises to ensure production safety and product quality.
