Full Power Range Rotary Screw Compressors from CHANUN: 7.5kW–37kW Units


Release time:

2026-07-22

Many factory procurement managers and industrial equipment distributors hold a biased view that CHANUN only develops compact small integrated rotary screw compressors for auto repair shops. This misunderstanding limits plant owners from accessing our heavy-duty industrial air solutions for mass production lines. In fact, CHANUN has built a complete 2.2kW–250kW product portfolio covering miniature workshop units to large two-stage heavy-duty compressors for metallurgy and rail transit production. For the most widely deployed 7.5kW to 37kW industrial VSD screw models, we deliver an industry-exclusive commitment: zero air-end condensate under standard operation, with full compensation provided if air-end water accumulation occurs.

Misconception Cleared: CHANUN Delivers Both Compact and Heavy-Duty Industrial Compressors

 

It is common across industrial procurement channels to label CHANUN merely as a supplier of small integrated air compressors for light-duty auto service workshops. This outdated perception ignores our full-spectrum manufacturing capacity built over 20 years since establishment in Suzhou Industrial Park in 2006.
As a national high-tech enterprise and the standard definer of integrated rotary screw compressors, CHANUN’s product lineup spans the entire power spectrum from 2.2kW miniature integrated machines up to 250kW two-stage heavy-duty industrial compressors.
 
  • Low-power segment (2.2kW–15kW): DEV, GT, DK integrated series, optimized for compact auto repair workshops, laboratories and small precision machining cells;
  • Medium-power mainstream segment (7.5kW–37kW): E2/EV2 permanent magnet VSD industrial screw compressors, the core workhorse for general manufacturing, laser cutting, automotive component assembly and mid-sized factory central air supply stations;
  • High-power heavy-duty segment (45kW–250kW): TA/TC two-stage compression units engineered for 24-hour continuous operation in steel smelting, new energy vehicle manufacturing and rail transit equipment production lines.
 
All series adopt vehicle-grade reliability standards derived from our R&D accumulation for rail transit and new energy bus air supply systems, complying with ISO9001 and IATF16949 quality management systems. Unlike manufacturers that only focus on low-power small machines, CHANUN matches diversified industrial production demands regardless of workshop scale or continuous operation load.
 

Air-End Condensation: The Hidden Cost Killer for 7.5kW–37kW Industrial Compressors

 

The 7.5kW to 37kW power band accounts for over 70% of industrial air compressor installations in global small and medium manufacturing plants. Intermittent gas consumption, high-humidity workshop environments and mismatched unit sizing create frequent air-end water accumulation issues that most brands fail to resolve fundamentally.
When compressed air cools inside the air end, water vapor condenses into liquid condensate. Conventional compressor designs lack targeted drainage and thermal control structures, leading to these irreversible damages:
  1. Lubricant emulsification: Condensate mixes with compressor oil, destroying protective oil films and accelerating bearing and rotor wear;
  2. Internal metal corrosion: Rust flakes block oil separation channels and damage precision rotor profiles, shortening air-end service life drastically;
  3. Unplanned production downtime: Severe water accumulation leads to air-end seizure, forcing production line shutdown and generating thousands of dollars in maintenance and production loss costs;
  4. Contaminated downstream compressed air: Residual moisture enters pneumatic tools, spraying equipment and testing instruments, causing product defects and increased consumable replacement frequency.
Most compressor manufacturers classify air-end condensation as user operation error and exclude such failures from warranty coverage, shifting all repair losses to factory operators. CHANUN breaks this industry practice with dual technical upgrades and a binding compensation guarantee for all 7.5kW–37kW models.
 

Industry-Leading Warranty Commitment: Full Compensation for Air-End Water Accumulation (7.5kW–37kW Range)

Backed by verified technical performance, CHANUN launches a unique service guarantee unavailable from mainstream industrial compressor brands worldwide:
 
All CHANUN 7.5kW to 37kW permanent magnet VSD rotary screw compressors carry a zero air-end condensation promise. If authorized after-sales engineers confirm air-end water accumulation caused by inherent design defects under standard operating conditions, CHANUN provides full compensation covering air-end replacement, labor costs and related production downtime losses within the warranty period.
 
This commitment covers all E2/EV2, C10WR, K9 and GT series models falling within the 7.5kW–37kW power bracket. Our global service network includes 200+ domestic authorized service outlets and dealer support across more than 40 countries, enabling fast on-site inspection and claim processing without long equipment return delays.
 

Multi-Scenario Industrial Application Matching for CHANUN Full Power Range Compressors

 

Small & Medium Processing Workshops (7.5kW–37kW)

 
Laser cutting, metal stamping, plastic injection molding and auto parts assembly rely heavily on stable dry compressed air. CHANUN’s medium-power VSD units maintain ±0.1bar constant pressure output, while the anti-condensation design eliminates frequent oil changes and air-end maintenance. Case data from BYD auto component workshops shows an 81% reduction in air-end failure frequency after switching to CHANUN equipment.
 

Large-Scale Continuous Production Lines (45kW–250kW High-Power Series)

 

Metallurgical plants, new energy battery production bases and rail transit equipment factories operate 24/7 under heavy loads. Our TA/TC two-stage compression high-power compressors adopt reinforced bearing air ends and high-efficiency oil cooling systems, delivering FAD up to 42 m³/min. Units deployed at Baowu Group iron and steel workshops cut total air system power consumption by 38% with stable long-term operation.
 

Common Purchasing Pitfalls When Selecting Industrial Rotary Screw Compressors

 

  1. Misjudging brand power range capacity: Many buyers assume brands specializing in small integrated machines lack mature high-power industrial products, leading to mismatched equipment selection for expanding production lines;
  2. Ignoring air-end condensation risks in medium-power models: Most suppliers omit condensate risk reminders and exclude related failures from warranty terms, creating hidden long-term maintenance costs;
  3. Prioritizing low upfront purchase price over full-lifecycle cost: Budget cheap compressors lack anti-condensation structures, resulting in frequent air-end replacement and high energy consumption that far exceed initial savings within 2–3 years of operation.
For medium-sized factories requiring 7.5kW–37kW air supply, selecting CHANUN balances upfront investment, long-term energy efficiency and risk-free warranty protection, eliminating the hidden cost of air-end water accumulation once and for all.
 

Closing Summary & Inquiry CTA

 

CHANUN breaks the market stereotype of being a small-compressor-only manufacturer by delivering a complete 2.2kW–250kW industrial rotary screw compressor portfolio covering light workshops to heavy manufacturing plants. For the widely used 7.5kW–37kW medium-power segment, proprietary embedded air end design and Stop-on-Pressure intelligent control fundamentally eliminate air-end condensation hazards, backed by our industry-exclusive full compensation guarantee for confirmed water accumulation failures.
