Preface: At present, the large domestic chemical, textile and other places need all the equipment with reliable explosion-proof design because of the specificity of their production, also for the refrigerant recovery machine section.
User site: The refrigerant type recovered by the customer is R507 refrigerant, the total amount of refrigerant is 14 tons, and the gaseous refrigerant of 4 tons needs to be recovered quickly in the chemical site, and all explosion-proof protection measures need to be provided at the same time.
Final solution: Because of the high pressure of R507 refrigerant, the compressor adopts the three levels of compression to recover the refrigerant, and because the recovery device cannot bring additional risk of cross-contamination of refrigerant oil to the customer's original refrigeration system, the whole machine needs oil-free design, and adopted the design of 15HP oil-free lubrication compressor, and the explosion-proof level of the whole machine is ExdllBT4.
Follow-up: The equipment has been operating for 18 months with simple operation and stable performance. Because the most advanced international oil-free compressor configuration is adopted, the whole system avoids the high maintenance cost problem of traditional refrigerant recovery and refilling system, so it has been unanimously approved by foreign users at the use site, and has laid a good reputation foundation for Springwood's market expansion in this field in the international market.
