Corken 691 – LPG Reciprocating Compressors (Non Oil-Free)
Single packed compressors are typically used in non-toxic, non-corrosive applications where oil-free gas and leakage containment are not critical. LPG (propane & butane), agricultural ammonia, and natural gas applications are where a single packed compressor fits well.
- Utilizes one set of V-ring packing per piston rod
- No distance piece between the cylinder and crosshead guide
- Not oil free
- Single stage compression
- Ideal for non-toxic, non-corrosive applications where oil-free gas and leakage containment are not critical
Features and Benefits for Corken 691
- Why select a compressor to transfer LPG and NH3? – Many LPG piping systems do not provide ideal NPSH conditions for liquid pumps. As a result, the poor NPSH conditions lead to excessive pump maintenance. Since compressors are only exposed to vapors, they are not affected by poor NPSH conditions. A compressor is the perfect solution for transferring liquids to and from tanks with unloading connections on the top (e.g. tank cars and underground tanks)
- Maximum versatility… – A compressor can be piped for multiple plant applications. Many times a tank car unloading compressor is utilized to load and unload trucks as well. Common applications include liquid transfer between tanks, off-load/load-out liquids, vapor recovery, and performing tank evacuation for maintenance purposes.
- Several models to match your needs… – Corken offers five sizes of vertical, single-stage compressors (Models 91, 291, 491, 691, and 891) for LPG/NH3 applications. The compressors are available with threaded NPT or Class 300 RF flanged connections and cover a full range of capacities ranging from 4.1 to 117 cfm (7.0 to 198.8 m3/hr) of liquid transfer. The Class 300 RF flange dramatically improves leakage containment and structural integrity
- Piston rod packing design…
- Single-stage design…
- Single-acting designs with a wide range of capacities…
- Double-acting design for even greater capacity…
- Maintenance made simple…
- Designed for a variety of applications…
- Custom engineered compressor packages available…
