Advantages
Fast field deployment
Full skid mounted pre assembly reduces on site piping and wiring work, shortening commissioning cycle for rapid put into operation.
Multi scenario adaptability
Compatible with electric motor, diesel engine and natural gas engine drive, matching grid power, field and offshore powerless environments.
Three cooling solutions for all climates
Open loop water cooling, closed loop water cooling and axial fan mixed cooling adapt to water sufficient, water scarce and mobile operation sites.
Low vibration stable operation
Horizontal double row symmetrical cylinder structure fully balances secondary inertia force, minimizing vibration and foundation fatigue during long term operation.
Full automatic safety protection
PLC system monitors pressure, temperature, lubrication and vibration in real time. Soft start, variable frequency start and automatic blow down avoid liquid compression and over temperature faults.
Application
This D Series is widely used in pipeline pressure testing, aerospace testing, metallurgy and steel manufacturing, scientific research inspection, membrane nitrogen production, down hole gas injection, offshore platform operation and urban gas supply stations. It provides stable medium and high pressure gas sources for industrial testing, gas production and gas injection processes.
FAQ
Q: How to select the correct cooling mode for different working sites?
A: Open loop cooling is used for fixed workshops with sufficient water resources. Closed loop cooling saves water for dry areas. Axial fan mixed cooling suits offshore, mobile and water limited working conditions.
Q: In what scenarios is mixed axial fan cooling irreplaceable?
A: It is specially designed for offshore platforms, movable skid stations and water shortage sites. It reduces reliance on cooling water and ensures continuous operation in harsh marine and desert environments.
Q: Why can this unit adapt to both fixed factory and mobile field projects?
A: It integrates multi drive and multi cooling modes. It matches grid power and water cooling for factories, and adapts fuel drive and air assisted cooling for temporary mobile field operations.
Q: What causes most failures in medium pressure compression and how does PLC avoid it?
A: Frequent failures are mainly caused by over temperature and residual liquid compression. The PLC system tracks real time temperature and condensate status, and executes active blowdown and load adjustment to avoid abnormal shutdown.
Q: What model selection logic applies for pipeline pressure testing?
A: Select low displacement models (1.5‑4 m³/min) for small diameter pipeline static pressure test; choose large displacement models (6‑10 m³/min) for fast pressurization and large scale pipeline engineering.
Q: What environment limits affect long term operation of D series compressors?
A: Closed water cooling is prohibited in severely dusty sites to avoid pipeline clogging. Mixed cooling is recommended for high salt fog offshore environments to reduce corrosion on cooling components.
