Features of PDC Compressors

Triple diaphragm construction and unique hydraulic oil system of our compressor design offers these important features:

• Contamination-free, leak-tight compression - Elastomeric seals assure total separation of the hydraulic fluid from the process gases/liquids.
• Triple Diaphragm Construction - Isolates process gas from hydraulic oil. This ensures no contamination to the compressed gases, so product purity is maintained even during upset conditions.
• Compatible Materials of Construction - All process-wetted components are constructed from corrosion-resistant material to prevent any contamination to the process gas.
• Filters and Oil Removal Systems Are Not Necessary - Hydraulic oil cannot migrate into the process gas.
• Extended Diaphragm Life - Advanced cavity contour design and unique proprietary manufacturing process reduces diaphragm stresses and prolongs fatigue life. Increasing diaphragm life extends maintenance intervals.
• Automatic Positive Priming - Injection pump design minimizes knocks, Cavitation, and vibrations, resulting in smooth start-up and operation.
• Soft, High-Strength Plastics for Check Valves - Reduce leakage, improve efficiency, extend equipment life, and reduce noise levels.
• High Compression Ratio per Stage - When compared to reciprocating compressors -helps reduce capital costs
• Unique Oil Distribution System - Assures pressure equalization
• Fast acting Leak Detection System - To detect and indicate diaphragm and seal failure

Horizontally-Opposed Designs for High-Efficiency Operation

• Duplex and multi-stage designs are available to accommodate a wide range of pressures and flows.
• Duplex units are capable of compressing different gases simultaneously.
• Simplex units are field-convertible to increase flow.
• Duplex units provide twice the flow with 1/3 Hp consumption.
• Horizontally-opposed and balanced designs reduce vibration and require minimal foundation.
