Engineered to deliver 42 m³/min at 1.00 MPa discharge pressure, the LW-42/10 is a two-stage, two-row oil-free piston nitrogen compressor purpose-built for high-pressure cryogenic air separation, demanding VPSA nitrogen boosting, and critical petrochemical pipeline distribution. Zero lubricant contamination, continuous-duty rated, and optimized for 24/7 operation at elevated pressure.

製品概要

の LW-42/10 nitrogen compressor represents a specialized high-pressure solution within our oil-free piston compressor portfolio, engineered for industrial applications where both substantial flow and elevated discharge pressure are non-negotiable requirements. With a rated capacity of 42 m³/min そして並外れた 1.00 MPa discharge pressure, this unit occupies a unique position at the intersection of high-flow and high-pressure nitrogen compression.

What distinguishes the LW-42/10 from conventional alternatives is its 完全にオイルフリーの圧縮経路 utilizing self-lubricating PTFE composite piston rings and rider bands. These advanced sealing elements operate without any hydrocarbon lubricants, ensuring the nitrogen product stream remains completely free of oil contamination. This intrinsic oil-free characteristic delivers ISO 8573-1 クラス0認証 natively, eliminating the need for downstream oil-removal filtration systems that would otherwise be mandatory in food processing, pharmaceutical manufacturing, semiconductor fabrication, and petrochemical applications.

主な特長とエンジニアリング上の利点

1. High-Temperature PTFE Composite Sealing Technology

The LW-42/10 employs a proprietary 自己潤滑ピストンリングおよびライダーバンドアセンブリ manufactured from high-performance PTFE composites reinforced with glass fiber, carbon fiber, and bronze particulates. This advanced material formulation achieves a coefficient of friction below 0.06 without any external hydrocarbon lubrication, completely eliminating oil vapor carryover into the nitrogen product stream. Critically, the PTFE composite is specifically engineered for the elevated discharge temperatures associated with 1.00 MPa operation, maintaining dimensional stability and sealing integrity up to 200°C. For industrial gas operators, this delivers native ISO 8573-1 Class 0 compliance without downstream filtration capital costs or energy penalties.

2. High-Pressure Two-Stage Thermodynamic Optimization

の 2段階圧縮アーキテクチャ of the LW-42/10 is thermodynamically optimized for the demanding 1.00 MPa discharge pressure target. By dividing the overall pressure ratio between a low-pressure cylinder and a high-pressure cylinder, the compressor achieves a significantly lower mean effective temperature per stage compared to single-stage designs. A dedicated high-efficiency shell-and-tube intercooler between stages removes the heat of compression, maintaining discharge temperatures below 160°C even at maximum continuous load. This thermal management is essential for preserving PTFE ring integrity at high pressure ratios and extends valve plate service life by approximately 45% versus single-stage alternatives operating at equivalent pressure ratios.

3. Reinforced Cast-Iron Frame for High-Pressure Service

メインフレームは鋳造されています GG25 グレー鋳鉄 (equivalent to ASTM A48 Class 30B) with thicker wall sections and integral cooling water passages specifically designed for the mechanical stresses of 1.00 MPa discharge pressure. The two-row opposed-cylinder arrangement provides natural first-order force cancellation, reducing unbalanced inertia forces transmitted to the foundation by over 80% compared to single-row designs. This mechanical advantage permits installation on a reinforced concrete inertia block of 10–12 tonnes, significantly reducing civil engineering costs compared to the 18+ tonne foundations required for equivalent single-row high-pressure compressors.

4. Flexible Voltage Configuration for Industrial Integration

The LW-42/10 is driven by a 315 kW induction motor available in 380V, 6kV, or 10kV configurations, conforming to IEC 60034-1 efficiency class IE3. The flexible voltage options allow direct integration into diverse industrial electrical infrastructures. The 380V configuration suits facilities with existing low-voltage distribution, while the 6kV and 10kV options eliminate the need for step-down transformers in plants with medium-voltage bus systems. This electrical adaptability reduces infrastructure costs, minimizes power transmission losses, and simplifies commissioning.

アプリケーションシナリオ

High-Pressure Cryogenic Air Separation Distribution

In large cryogenic ASU facilities producing high-purity gaseous nitrogen, the LW-42/10 serves as the 一次高圧窒素ブースター for distribution networks requiring 1.00 MPa header pressure. The 42 m³/min capacity aligns with the output of medium-to-large ASUs, while the elevated discharge pressure overcomes significant pipeline friction losses over long distribution distances. This is particularly valuable in integrated industrial complexes where nitrogen must be transported 3–5 km from the ASU to downstream consumers such as steel mills, chemical plants, and LNG facilities. The oil-free design ensures that nitrogen purity is preserved throughout the distribution chain.

High-Pressure VPSA Nitrogen Booster Stations

For large VPSA nitrogen generators producing 99.5–99.9% purity nitrogen at near-atmospheric pressure, the LW-42/10 nitrogen booster compresses the low-pressure product to 1.00 MPa for high-pressure distribution. The elevated discharge pressure is essential for VPSA installations serving multiple consumers through extensive distribution networks where pressure losses are significant. The oil-free compression path is absolutely critical in VPSA service because hydrocarbon contamination would permanently poison the carbon molecular sieve adsorbent, degrading separation efficiency and necessitating costly adsorbent replacement that could exceed $50,000 for a large VPSA unit.

Petrochemical High-Pressure Reactor Inerting

In petrochemical and refining operations, the LW-42/10 provides high-pressure nitrogen for reactor inerting during catalyst changeout, emergency vessel purging, and high-pressure pipeline displacement. The 1.00 MPa discharge pressure is sufficient to overcome the pressure ratings of typical high-pressure process vessels and reactor systems, allowing direct nitrogen injection without intermediate boosting. This capability is particularly valuable during emergency shutdown procedures where rapid nitrogen inerting is required to prevent explosive atmosphere formation in process equipment operating at elevated pressures.

High-Pressure Food Packaging & Aseptic Processing

Large-scale food and beverage facilities utilizing high-pressure aseptic processing, HPP (High Pressure Processing) pre-treatment nitrogen pressurization, and high-speed modified atmosphere packaging require nitrogen at elevated pressures. The LW-42/10’s 1.00 MPa discharge pressure supports high-pressure nitrogen injection into aseptic filling lines and HPP vessels, while its oil-free certification ensures compliance with FDA 21 CFR 173.310 and EU Regulation 231/2012. The 42 m³/min capacity can simultaneously supply multiple high-speed packaging lines and aseptic processing stations.

材料と構造

The LW-42/10 is constructed from premium materials selected for high-pressure nitrogen compatibility, corrosion resistance, and extended operational life:

すべての圧力支持部品は、以下の基準に厳密に従って設計および製造されています。 ASME BPVC セクション VIII ディビジョン 1 or Chinese GB 150 standards. Every weld joint undergoes 100% radiographic inspection (RT) per ASME Section V, Article 2, and each completed pressure vessel is subjected to a hydrostatic pressure test at 1.5 times the maximum allowable working pressure (MAWP) for a minimum hold period of 30 minutes.

設置およびメンテナンスに関するガイドライン

基礎および構造要件

The LW-42/10 has a dry weight of 6.00 tonnes and a center of gravity approximately 950 mm above the baseplate. Due to the two-row opposed-cylinder design, unbalanced forces are minimal despite the high-pressure operation, permitting installation on a reinforced concrete inertia block of 10–12 tonnes. The block should be mounted on elastomeric vibration isolators (natural frequency 6–8 Hz) to prevent vibration transmission to adjacent structures. 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.

冷却水システムの設計

冷却水の需要は約 48 m³/h at an inlet temperature not exceeding 32°C. The water distribution circuit supplies the cylinder jackets, intercooler, and aftercooler in parallel branches. Water quality specifications: pH 6.5–8.5, 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 CaCO₃. For sites with marginal water quality, a closed-loop cooling tower with side-stream filtration and chemical treatment is strongly recommended to prevent scale formation and corrosion in the high-pressure cooling circuits.

予防保守スケジュール

The oil-free design of the LW-42/10 dramatically reduces maintenance complexity compared to lubricated alternatives. There are no oil changes to schedule, no lubricating oil samples to analyze, no oil filter elements to replace, and no oil separator cartridges to monitor. The primary consumable wear items are the PTFE製ピストンリングおよびライダーバンド, which typically achieve 4,000–6,000 hours of service life under clean nitrogen conditions at high pressure. This maintenance simplification translates to lower labor costs, reduced spare parts inventory, and higher equipment availability.

法令遵守および安全認証

The LW-42/10 nitrogen compressor is designed, manufactured, and tested to meet or exceed the following international standards and regulatory frameworks:

パフォーマンスと効率の分析

The LW-42/10 achieves a specific power consumption of approximately 7.50 kW per m³/min of nitrogen delivered at 1.00 MPa discharge pressure. This efficiency metric is commendable for an oil-free piston compressor operating at a high pressure ratio, positioning the unit competitively within the 30–50 m³/min high-pressure capacity class. For comparison, oil-lubricated screw compressors in similar high-pressure applications typically consume 7.8–8.8 kW/m³/min, while diaphragm compressors (often selected for oil-free high-pressure service) can exceed 12 kW/m³/min.

Over a standard 8,000-hour annual operating schedule, the LW-42/10’s efficiency advantage generates approximately 96,000–240,000 kWh of annual energy savings compared to less efficient alternatives. At an average industrial electricity tariff of $0.08/kWh, this represents $7,680–$19,200 in direct operating cost reduction per year. When combined with the complete elimination of oil-related consumables (lubricating oil, filter elements, separator cartridges, waste oil disposal, and oil analysis), the 窒素圧縮の総所有コスト is reduced by an estimated 20–28% over a 10-year operational life.

The absence of oil in the compression path also eliminates the energy penalty associated with downstream oil-removal equipment. A typical oil-lubricated compressor of this size and pressure rating requires coalescing filters, activated carbon adsorbers, and continuous oil monitoring instrumentation that collectively consume 3–5% of the compressor’s power output. The LW-42/10’s oil-free design removes this parasitic load entirely, further improving effective system efficiency.
