Pr\u00e9sentation du produit<\/h2>\n

Le ZW-13\/30 nitrogen compressor<\/strong> represents a powerful mid-range solution within our oil-free piston compressor family, engineered for applications where both substantial flow capacity and high discharge pressure are simultaneously required. With a rated capacity of 13 m\u00b3\/min<\/strong> et une pression de refoulement de 3,00 MPa<\/strong>, this unit occupies a critical position in the high-pressure nitrogen compressor market, bridging the gap between small laboratory-scale units and massive industrial boosters.<\/p>\n

What distinguishes the ZW-13\/30 from conventional alternatives is its circuit de compression enti\u00e8rement exempt d'huile<\/strong> utilizing self-lubricating PTFE composite piston rings and rider bands. This design philosophy eliminates any possibility of hydrocarbon contamination in the nitrogen product stream, achieving Certification ISO 8573-1 Classe 0<\/strong> natively. At 3.00 MPa discharge pressure, the risk of oil vapor carryover is substantially magnified compared to low-pressure applications, making the oil-free design not merely advantageous but absolutely mandatory for food-grade, pharmaceutical, and electronics-grade nitrogen service.<\/p>\n

L'architecture du compresseur utilise un \u00e0 deux \u00e9tages, \u00e0 trois rang\u00e9es (\u4e8c\u5217\u4e09\u7ea7)<\/strong> configuration that is essential for managing the extreme pressure ratio required to achieve 3.00 MPa from typical inlet conditions. The three-row opposed-cylinder arrangement provides superior force balance compared to two-row designs, reducing vibration transmission and permitting installation on lighter foundations. Each compression stage is equipped with an independent high-efficiency intercooler, ensuring gas temperatures remain within safe operating envelopes even during sustained maximum-load operation. The robust cast-iron frame and dynamically balanced forged steel crankshaft are rated for a minimum service life of 120 000 heures<\/strong> conform\u00e9ment aux protocoles de maintenance standard.<\/p>\n

Principales caract\u00e9ristiques et avantages techniques<\/h2>\n

1. Three-Row Opposed-Cylinder Force Balance<\/h3>\n

The ZW-13\/30 employs a unique three-row opposed-cylinder arrangement (\u4e8c\u5217\u4e09\u7ea7)<\/strong> that provides exceptional first-order and second-order force cancellation. By distributing the compression work across three cylinders arranged in an opposed configuration, the compressor achieves near-perfect inertial force balance, reducing vibration transmission to the foundation by over 90% compared to single-row designs. This mechanical advantage is particularly critical for high-pressure compressors where the peak gas forces on the pistons are substantially higher than in low-pressure applications. The three-row design permits installation on a lighter reinforced concrete inertia block (minimum 10 tonnes versus 15+ tonnes for equivalent single-row units), significantly reducing civil engineering costs and simplifying retrofit installations in existing process plants.<\/p>\n

2. High-Pressure Oil-Free PTFE Composite Sealing<\/h3>\n

The ZW-13\/30 utilizes a proprietary ensemble segment de piston et bande de guidage autolubrifiants<\/strong> manufactured from high-density PTFE composites specifically formulated for high-pressure service. These rings are reinforced with glass fiber and bronze particulates to achieve a coefficient of friction below 0.05 without any external hydrocarbon lubrication. At 3.00 MPa discharge pressure, the partial pressure of oil vapor would be approximately 10 times higher than at 0.30 MPa, making oil contamination far more concentrated and difficult to remove. The ZW-13\/30’s native oil-free design achieves Certification ISO 8573-1 Classe 0<\/strong> without any downstream filtration, eliminating both the capital cost and the energy penalty of oil-removal equipment. The PTFE formulation is rated for continuous operation at temperatures up to 185\u00b0C, ensuring reliable sealing integrity under the extreme thermal stress of high-pressure compression.<\/p>\n

3. Two-Stage Thermodynamic Optimization for Extreme Pressure Ratios<\/h3>\n

Le architecture de compression \u00e0 deux \u00e9tapes<\/strong> of the ZW-13\/30 is thermodynamically essential for achieving the 3.00 MPa discharge pressure target from typical inlet pressures of 0.05\u20130.10 MPa. The overall pressure ratio of approximately 30:1 to 60:1 is divided between a low-pressure cylinder group and a high-pressure cylinder group, with each stage operating at a manageable pressure ratio. A high-efficiency shell-and-tube intercooler between stages removes the substantial heat of compression, maintaining discharge temperatures below 160\u00b0C and preventing thermal degradation of the PTFE sealing elements. Without staged compression, the discharge temperature would exceed 250\u00b0C, far beyond the safe operating limit of any oil-free sealing material. The inter-stage cooling is therefore not merely an efficiency enhancement but a fundamental requirement for reliable high-pressure oil-free operation.<\/p>\n

4. Standard 380V Industrial Motor Drive with High Efficiency<\/h3>\n

The ZW-13\/30 is driven by a moteur \u00e0 induction triphas\u00e9 de 160 kW, 380 V, 50 Hz<\/strong> conforming to IEC 60034-1 efficiency class IE3. The standard low-voltage configuration integrates directly into existing 380V industrial distribution panels without requiring medium-voltage switchgear or step-down transformers. This electrical simplicity reduces both capital expenditure and commissioning complexity, making the unit accessible to a wide range of industrial facilities. For sites with 6kV or 10kV bus systems, an optional motor with integrated step-down transformer can be supplied on a common skid, providing seamless integration into any electrical infrastructure.<\/p>\n

Sc\u00e9narios d'application<\/h2>\n

Stations de remplissage de bouteilles d'azote haute pression<\/h3>\n

The ZW-13\/30 is ideally suited for industrial nitrogen cylinder filling operations<\/strong> where high-pressure gas must be compressed into standard industrial cylinders at 15\u201320 MPa filling pressure. While the compressor’s 3.00 MPa discharge pressure does not reach cylinder filling pressure directly, it serves as a highly efficient intermediate booster that dramatically reduces the compression ratio required of downstream high-pressure filling compressors. The 13 m\u00b3\/min capacity can supply multiple filling manifolds simultaneously, making the ZW-13\/30 suitable for commercial gas filling stations serving industrial, medical, and specialty gas markets. The oil-free design is mandatory for cylinder filling because any oil contamination would be trapped in the cylinders and delivered to end-users, potentially compromising their processes and creating liability exposure.<\/p>\n

\"ZW-13\/30<\/p>\n

Petrochemical High-Pressure Process Nitrogen<\/h3>\n

Dans les op\u00e9rations p\u00e9trochimiques et de raffinage, ZW-13\/30 high-pressure nitrogen compressor<\/a> provides nitrogen for reactor catalyst preservation, emergency injection into high-pressure vessels, pipeline pressure testing, and hydrostatic testing of process equipment. The 3.00 MPa discharge pressure is sufficient to inject nitrogen into process vessels operating at pressures up to 2.5 MPa, maintaining positive inert gas blankets during startup, shutdown, and upset conditions. The continuous-duty rating ensures uninterrupted nitrogen availability during extended turnaround campaigns. The oil-free certification is mandatory for petrochemical applications where nitrogen contacts catalyst beds or enters process streams that must remain completely hydrocarbon-free.<\/p>\n

Gas Liquefaction & Cryogenic Storage Booster<\/h3>\n

In nitrogen liquefaction plants and cryogenic storage facilities, the ZW-13\/30 compresses nitrogen from the liquefier vaporizer or storage tank boil-off to the pressure required for distribution or further processing. The 3.00 MPa discharge pressure is sufficient for feeding high-pressure nitrogen into cryogenic storage systems, driving nitrogen through heat exchangers, and supplying high-pressure consumers in the process plant. The 13 m\u00b3\/min capacity matches the output of small to medium-scale liquefaction plants, making the ZW-13\/30 an ideal integrated booster for on-site nitrogen liquefaction systems. The oil-free design prevents contamination of the cryogenic equipment and ensures the purity of liquid nitrogen product.<\/p>\n

\"ZW-13\/30<\/p>\n

Pharmaceutical & Food-Grade High-Pressure Nitrogen<\/h3>\n

Pharmaceutical manufacturing and large-scale food processing facilities require high-purity nitrogen at elevated pressure for sterile filtration, spray drying, aseptic filling, and high-pressure packaging applications<\/strong>. The ZW-13\/30’s oil-free certification ensures compliance with FDA 21 CFR 211.72 and EU GMP Annex 1. The 3.00 MPa discharge pressure provides adequate head to drive nitrogen through sterile filtration systems, spray dryers, and high-pressure packaging equipment. The 13 m\u00b3\/min capacity can simultaneously supply multiple pharmaceutical process lines or food packaging stations within a single manufacturing facility, making the ZW-13\/30 a versatile central nitrogen supply solution.<\/p>\n<\/div>\n

Instructions d'installation et d'entretien<\/h2>\n

Exigences en mati\u00e8re de fondations et de structure<\/h3>\n

The ZW-13\/30 has a dry weight of 6.00 tonnes and a center of gravity approximately 900 mm above the baseplate. Thanks to the three-row opposed-cylinder design, unbalanced forces are minimal despite the high-pressure operation, permitting installation on a bloc d'inertie en b\u00e9ton arm\u00e9 de 10 \u00e0 12 tonnes<\/strong>. The block should be mounted on elastomeric vibration isolators (natural frequency 6\u20138 Hz). Minimum clearance requirements: 1.5 m on the non-drive side for valve access, 1.2 m on the drive side for motor maintenance, and 2.0 m overhead for crane access during major overhauls. Special attention must be paid to the high-pressure discharge piping, which must be properly supported, anchored, and stress-relieved to prevent vibration-induced fatigue at 3.00 MPa.<\/p>\n

Conception du syst\u00e8me d'eau de refroidissement<\/h3>\n

La demande en eau de refroidissement est d'environ 28 m\u00b3\/h<\/strong> at an inlet temperature not exceeding 32\u00b0C. The water distribution circuit supplies the cylinder jackets, intercooler, and aftercooler in parallel branches. Given the extreme pressure ratio, the intercooler is absolutely critical for thermal management and must receive priority cooling water flow at all times. Water quality specifications: pH 6.5\u20138.5, total dissolved solids < 500 mg\/L, chloride content < 50 mg\/L (to prevent SS316 tube corrosion), suspended solids < 30 mg\/L, and total hardness < 300 mg\/L as CaCO\u2083. A closed-loop cooling tower with side-stream filtration and chemical treatment is strongly recommended for all installations to ensure consistent water quality.<\/p>\n

The oil-free design of the ZW-13\/30 dramatically simplifies maintenance compared to lubricated alternatives. There are no oil changes, no oil analysis, no filter replacements, and no separator cartridge changes. The primary consumable wear items are the segments de piston et bagues de guidage en PTFE<\/strong>, which typically achieve 3,000\u20135,000 hours of service life under clean nitrogen conditions at high pressure. The high-pressure valve plates may require more frequent inspection than low-pressure equivalents due to the increased mechanical stress at 3.00 MPa, but the overall maintenance burden remains significantly lower than oil-lubricated systems.<\/p>\n

Nitrogen is classified as a simple asphyxiant gas. At 3.00 MPa discharge pressure, the risk of rapid gas release and oxygen displacement is severely elevated. All ZW-13\/30 installations must incorporate continuous oxygen deficiency monitoring in the compressor room and all adjacent areas. High-pressure discharge piping must be equipped with pressure relief valves rated at 110% of MAWP and rupture discs as secondary protection. All high-pressure connections must be verified with ultrasonic leak detection before commissioning. Ventilation systems must maintain ambient oxygen above 19.5% per OSHA 29 CFR 1910.146. Emergency shutdown interlocks should activate at 19.5% O\u2082 (alarm) and trigger automatic isolation at 18.0% O\u2082 (hard shutdown). Personnel must be trained in high-pressure gas safety protocols and must never attempt to disconnect pressurized lines.<\/p>\n<\/div>\n

Analyse des performances et de l'efficacit\u00e9<\/h2>\n

The ZW-13\/30 achieves a specific power consumption of approximately 12.31 kW per m\u00b3\/min<\/strong> of nitrogen delivered at 3.00 MPa discharge pressure. This specific power figure reflects the thermodynamic reality of ultra-high-pressure compression, where the work required increases substantially with pressure ratio. Within the high-pressure oil-free piston compressor segment (discharge pressure >2.50 MPa), this efficiency is competitive and often superior to diaphragm compressors, which are the primary alternative for oil-free high-pressure service. For comparison, oil-lubricated reciprocating compressors in similar ultra-high-pressure applications typically consume 13.0\u201315.0 kW\/m\u00b3\/min, while diaphragm compressors may exceed 18 kW\/m\u00b3\/min.<\/p>\n

Over a standard 8,000-hour annual operating schedule, the ZW-13\/30’s efficiency advantage versus less efficient alternatives yields approximately 60,000\u2013140,000 kWh of annual energy savings<\/strong>. At $0.08\/kWh, this represents $4,800\u2013$11,200 in direct electricity cost reduction per year. However, the primary economic driver for ZW-13\/30 selection is typically the \u00e9limination des consommables li\u00e9s au p\u00e9trole et \u00e9vitement des \u00e9quipements de d\u00e9graissage en aval<\/strong> that would be mandatory with lubricated alternatives. At 3.00 MPa, the partial pressure of oil vapor is approximately 15 times higher than at 0.30 MPa, making downstream oil-filtration systems exponentially more expensive and less effective. The co\u00fbt total de possession pour la compression d'azote \u00e0 ultra-haute pression<\/a> is reduced by an estimated 25\u201335% over a 10-year operational life when oil-free operation is compared to lubricated systems with full downstream purification.<\/p>\n

The absence of oil in the compression path is particularly critical at 3.00 MPa because oil contamination becomes highly concentrated and virtually impossible to remove to the levels required by food-grade, pharmaceutical, and semiconductor applications. The ZW-13\/30’s native oil-free design eliminates this challenge entirely, providing guaranteed product purity without the complexity and cost of downstream purification trains.<\/p>\n<\/div>\n
