Piston rod packings for reciprocating compressors have always been prone to gas leakage – until now. Hoerbiger’s Xperseal rod sealing system uses pres- surised oil to keep the gas in place, ensuring genuinely leak-free sealing for the lifetime of the compressor. This sealing system is fail-safe, can be retrofitted easily to existing compressors, and uses no more oil than a conventional lubricated packing.
Oil is supplied to the packing by a dedicated hydraulic oil-supply unit that monitors oil pressure, temperature, and level. An integrated cooler eliminates the need for water cooling of the packing, so clogged cooling channels and gas contamination of the cooling circuit are things of the past. In the event of an unexpected oil pressure loss, the system switches automatically to a malfunction mode that replicates a standard vented or purged packing.
