Өнімге шолу

The ZW-5.3/16 nitrogen compressor represents a specialized high-pressure solution within our oil-free piston compressor family, engineered for applications where elevated discharge pressure is the primary operational requirement. With a rated capacity of 5.3 m³/min және ерекше 1.60 MPa discharge pressure, this unit occupies a unique position in the industrial nitrogen compression landscape—bridging the gap between conventional low-pressure boosters and ultra-high-pressure gas filling systems.

What distinguishes the ZW-5.3/16 from conventional alternatives is its толығымен майсыз сығымдау механизмі utilizing self-lubricating PTFE composite piston rings and rider bands. This design philosophy eliminates any possibility of hydrocarbon contamination in the nitrogen product stream, making the unit immediately suitable for high-purity nitrogen cylinder filling, pharmaceutical-grade nitrogen injection, and electronics process gas supply without additional downstream purification equipment. The oil-free certification is particularly critical at 1.60 MPa because oil contamination at elevated pressure becomes more difficult and costly to remove.

Негізгі ерекшеліктері және инженерлік артықшылықтары

1. Жоғары қысымды майсыз PTFE тығыздау технологиясы

The ZW-5.3/16 employs a proprietary self-lubricating piston ring and rider band system manufactured from high-performance PTFE composites reinforced with glass fiber and bronze particulates, specifically formulated for high-pressure service. This material achieves a coefficient of friction below 0.08 without any external hydrocarbon lubrication, completely eliminating oil vapor carryover into the nitrogen stream. At 1.60 MPa, the risk of oil contamination becomes exponentially more problematic because oil droplets are more difficult to separate at elevated pressure, and any contamination becomes concentrated in the compressed gas. The ZW-5.3/16’s native oil-free design achieves ISO 8573-1 0 класына сәйкестік without downstream filtration, a critical advantage for cylinder filling and high-purity process applications.

2. Two-Stage Three-Row Compression Architecture

The two-stage, three-row configuration of the ZW-5.3/16 is uniquely engineered to achieve the high pressure ratio required for 1.60 MPa discharge. The three-row arrangement provides superior force balance compared to two-row designs, reducing vibration transmission and permitting installation on lighter foundations. The staged compression with inter-stage cooling limits the discharge temperature of each stage to below 160°C, preserving the integrity of the PTFE sealing elements and extending valve plate life. This thermal management is particularly critical at high pressure ratios where adiabatic compression temperatures would otherwise exceed the safe operating limits of polymer-based seals.

3. Compact Design for Space-Constrained Installations

Уақыты 1947 × 1900 × 2580 mm, the ZW-5.3/16 occupies remarkably little floor space for a high-pressure compressor of this capability. The compact footprint is achieved through an optimized vertical crankcase design that minimizes the machine’s longitudinal dimension while maintaining adequate maintenance access. The 3.97-tonne weight permits transportation and positioning using standard forklift equipment, eliminating the need for overhead cranes or specialized rigging. This portability makes the ZW-5.3/16 ideal for containerized nitrogen supply systems, mobile cylinder filling stations, and retrofit installations in existing compressor houses with limited floor space.

4. Standard 380V Direct-On-Line Motor Drive

The ZW-5.3/16 is powered by a 55 kW, 380V, 50Hz three-phase induction motor rated to IEC 60034-1 IE3 efficiency class. The standard low-voltage configuration integrates directly into existing 380V industrial distribution panels without requiring medium-voltage infrastructure, step-down transformers, or specialized switchgear. This electrical simplicity reduces both capital expenditure and commissioning complexity, making the ZW-5.3/16 an attractive option for facilities upgrading from bottled nitrogen or membrane generators to on-site high-pressure compression.

Қолдану сценарийлері

High-Pressure Nitrogen Cylinder Filling

The ZW-5.3/16 is purpose-built for nitrogen cylinder filling stations serving industrial gas distributors, welding supply companies, and specialty gas laboratories. Its 1.60 MPa discharge pressure is sufficient to fill standard industrial nitrogen cylinders to 15 MPa working pressure through a high-pressure booster or cascade system. The 5.3 m³/min capacity supports a filling rate of approximately 20–25 cylinders per hour (40L, 15 MPa), making it suitable for medium-volume filling operations. The oil-free design is mandatory for cylinder filling because any oil contamination would be concentrated in the compressed gas and could contaminate downstream processes when the cylinder is used.

Petrochemical High-Pressure Nitrogen Injection

In petrochemical and refinery operations, the ZW-5.3/16 provides high-pressure nitrogen for reactor inerting, catalyst preservation, emergency vessel purging, and pipeline pressure testing. The 1.60 MPa discharge pressure is sufficient to overcome the pressure ratings of most process vessels and reactor systems, allowing direct nitrogen injection without intermediate boosting. The ZW-5.3/16 high-pressure nitrogen compressor is particularly valuable for emergency response scenarios where rapid nitrogen injection is required to inert a vessel or suppress a runaway reaction. The oil-free certification is mandatory because nitrogen at 1.60 MPa entering a catalyst bed or process stream must remain completely hydrocarbon-free.

Pharmaceutical & Biotechnology Process Gas

Pharmaceutical manufacturing facilities require high-purity nitrogen for sterile process inerting, lyophilization (freeze-drying), and aseptic filling operations. The ZW-5.3/16’s oil-free certification ensures compliance with FDA 21 CFR, EU GMP Annex 1, and pharmacopeial nitrogen standards. The 1.60 MPa pressure is adequate for feeding high-pressure nitrogen distribution manifolds serving multiple sterile processing suites, autoclaves, and freeze-dryers. The compact footprint allows installation within pharmaceutical cleanroom support areas or utility corridors where space is severely constrained.

Electronics & Semiconductor Manufacturing

Semiconductor fabrication facilities require high-pressure nitrogen for wafer handling systems, chemical vapor deposition (CVD) processes, and ion implantation chamber purging. The ZW-5.3/16’s 1.60 MPa discharge pressure is sufficient for feeding the high-pressure nitrogen headers that serve process tools requiring elevated pressure for pneumatic actuation or process gas delivery. The oil-free design is absolutely non-negotiable in semiconductor applications because even trace oil contamination can cause catastrophic defects in integrated circuits, leading to yield losses measured in millions of dollars.

Алдын алу жұмыстарының кестесі

The oil-free design of the ZW-5.3/16 dramatically simplifies maintenance compared to lubricated alternatives. There are no oil changes, no oil analysis, no filter replacements, and no separator cartridge changes. The only consumable wear items are the PTFE поршень сақиналары және рульдік белдіктер, which typically achieve 3,000–5,000 hours of service under clean nitrogen conditions at high pressure.

Сәйкестік және қауіпсіздік сертификаттары

The ZW-5.3/16 nitrogen compressor meets the following international standards and regulatory requirements:

Өнімділік және тиімділік талдауы

The ZW-5.3/16 achieves a specific power consumption of approximately 10.38 kW per m³/min of nitrogen at 1.60 MPa discharge pressure. While this specific power is higher than low-pressure models due to the elevated pressure ratio, it remains competitive within the high-pressure oil-free piston compressor segment. For comparison, oil-lubricated reciprocating compressors at equivalent pressure ratios typically consume 11–13 kW/m³/min, and diaphragm compressors (often selected for high-pressure oil-free service) may exceed 15 kW/m³/min.

The primary economic advantage of the ZW-5.3/16 is not marginal energy savings but the elimination of oil-related consumables and downstream purification equipment. A typical oil-lubricated high-pressure compressor requires quarterly oil changes ($300–600/year), monthly oil analysis ($200–400/year), annual filter replacements ($500–1,000/year), and separator cartridge changes ($800–1,500/year). The ZW-5.3/16 eliminates all of these expenses, delivering total consumable savings of $1,800–$3,500 annually.

Additionally, the жоғары қысымды азот сығымдауының жалпы меншік құны is further reduced by eliminating the need for downstream oil-removal equipment. At 1.60 MPa, oil-filtration systems become significantly more complex and expensive, often requiring multi-stage coalescing filters followed by activated carbon adsorbers. The ZW-5.3/16’s native oil-free design removes this capital and operating burden entirely.
