Product Description

 

 

Product Description

LDH series liquid nitrogen equipment is based on the pressure swing adsorption principle, using high-quality carbon molecular sieve as adsorbent, under a certain pressure, from the air to produce nitrogen. After purifying and drying compressed air, pressure adsorption and decompression desorption are carried out in the absorber. Due to the kinetic effect, the diffusion rate of oxygen in the micropores of carbon molecular sieve is much higher than that of nitrogen. When the adsorption is not in equilibrium, nitrogen is enriched in the gas phase to form the finished nitrogen. Then decompression to atmospheric pressure, adsorbent adsorption of oxygen and other impurities, to achieve regeneration. Generally, two adsorption towers are set up in the system. One tower absorbs nitrogen and the other tower is desorption and regeneration. Automatic control by PLC program makes the two towers work alternately. The finished nitrogen is then passed through the refrigerator to produce liquid nitrogen.

After Sales Service

Service Scope

• Deliver professional technical consultation and operational training to customers.

• Preset spare parts in a planned manner to meet customers' needs, and implement emergency measures to address their urgent spare part requirements.

• Provide remote debugging services; on-site debugging support will be arranged if necessary.

• Offer remote visit services (at least once a year); on-site visit can be arranged upon mutual agreement if required.

• Collect customer demand information, accept customer quality objections, and promptly take corrective and preventive measures through remote communication.

Introduction to After-Sales Engineers

Our after-sales engineers have undergone rigorous professional skill training and strict assessments. Equipped with first-class technical expertise and comprehensive remote service capabilities, they provide high-quality services for global users.

Emergency Maintenance Schedule

• Provide a clear response to the user within 2 hours after receiving information about the failure of the user's equipment via remote communication channels.

• Provide remote technical guidance immediately after confirming the fault situation; if on-site service is necessary after remote diagnosis, professional personnel will arrive at the user's site within the agreed time frame to ensure the normal operation of the user's equipment.

Prices and Supply Channels of Main Spare Parts

Commonly used spare parts are available in stock year-round, with prices lower than the average market level. We provide efficient international logistics solutions for spare part supply.

Special Services

• Establish electronic user files to support users in equipment management remotely.

• Regularly remind users to replace wearing parts, conduct equipment inspections, and note key matters needing attention through online communication.

• Provide regular product usage tracking services and after-sales service consultations via video calls or online platforms.

• Set up an online after-sales service column for record-keeping and information inquiry.

Training Plan

• Train operators to proficiently operate the equipment through online training courses and video tutorials.

• Enable maintenance personnel to master the daily maintenance and repair work of the equipment via remote guidance and online training materials.

• During after-sales personnel's remote user visits: gain insights into users' equipment operation status through video checks, provide secondary training for operators via online sessions, and enhance operation and maintenance personnel's understanding of the equipment through remote technical exchanges. On-site training can be arranged if necessary and mutually agreed.
