KIMAIR PSM Series PM Motor Inverter Rotary Screw Air Compressors (ASME Certified)

The KIMAIR PSM Series not only inherits the high-efficiency and energy-saving features of permanent magnet variable speed technology, but its core competitiveness lies in its design and manufacturing process, which strictly follows and has obtained the ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code certification. This ensures that its pressure vessel components (such as the oil separator tank) meet one of the highest international safety standards in terms of design, material, welding, inspection, and quality control system.

KIMAIR Core Advantages

International Compliance, Global Access

Holds the ASME "U" Stamp, serving as a "technical passport" for product safety and quality widely accepted internationally (especially in the North American market), effectively breaking down international technical barriers.
Ultimate Safety and Reliability

Behind the ASME certification is a rigorous "prescriptive" code system. The PSM Series executes every step from material selection, welding procedures (adhering to strict WPS/PQR), non-destructive testing (e.g., 100% RT/UT), to final inspection according to this highest standard, fundamentally eliminating potential safety hazards and ensuring safe and reliable equipment operation throughout its lifecycle.
High-Efficiency Energy-Saving PM Core

Equipped with an IE5 ultra-high-efficiency Permanent Magnet (PM) synchronous motor and a high-efficiency screw airend, using direct drive transmission with 100% transmission efficiency. Compared to traditional fixed-speed compressors, it achieves comprehensive energy savings of 30%-50%, maintaining over 95% efficiency even when the load factor is below 20%.
Excellent Stability and Pressure Control

Utilizes high-frequency vector variable frequency technology to achieve precise, stepless speed regulation. Pressure control accuracy can reach ±0.1 bar, with a response time to air demand fluctuations of less than 2 seconds, ensuring extremely stable production air pressure.
Long Life

The Permanent magnet motor features a bearingless design, reducing potential failure points. Core components have a long design life, resulting in lower maintenance costs.
Intelligent Cloud Management Platform

Standard with an IoT module, supporting remote monitoring, energy efficiency analysis, predictive maintenance, and fault warning, enabling digital management.

Application Scenarios

This series is designed for situations requiring international compliance certification or top-tier safety and reliability:

- Export and International Projects: Products exported to North America or countries/regions requiring ASME standards.
- Process Industry & Critical Facilities: Key compressed air supply points in industries like petrochemical, natural gas, power energy where downtime is not allowed.
- High-Risk & Harsh Environments: Hazardous locations with explosive media or harsh conditions with high vibration and high loads.
- High-End Manufacturing & Precision Processes: Industries like semiconductor, automotive manufacturing, medicine/food (requires air treatment equipment) with stringent requirements for air source stability and safety.
- Major Infrastructure Projects: Engineering projects requiring complete international certification documentation for core power equipment.

Customer Frequently Asked Questions (FAQ)

Q1: What specific value does ASME certification bring us?

A: ASME certification is far more than just a certificate. It means: 1) Market Access: It is a mandatory or highly preferred passport for entering markets like North America; 2) Risk Mitigation: Its rigorous code significantly reduces legal and financial risks associated with pressure equipment safety accidents due to design, material, or manufacturing defects; 3) Quality Endorsement: It is a recognized quality and safety benchmark in tenders for high-end clients and large projects.

Q2: What is the manufacturing difference between the PSM Series and ordinary permanent magnet variable speed compressors?

A: The core difference lies in the full-process compliance control. The PSM Series must use ASME-approved materials, be welded by certified welders following qualified Welding Procedure Specifications (WPS), undergo stricter Non-Destructive Testing (NDT) (e.g., 100% radiographic testing on all pressure-bearing welds), and be jointly inspected on-site by an ASME Authorized Inspector (AI). All manufacturing data must be traceable, forming a complete ASME Data Report.

Q3: Does obtaining ASME certification mean the product is significantly more expensive?

A: The initial cost is indeed higher due to material, process, inspection, and certification fees. However, looking at the Total Cost of Ownership (TCO), the resulting ultra-high reliability, extremely low failure rate, longer service life, and premium market pricing capability yield a very high overall return on investment. This is especially true for applications where equipment failure leading to significant losses is unacceptable.

Q4: Which specific components does your ASME certification cover?

A: The certification for the PSM Series explicitly covers all pressure vessel components within the unit, primarily the oil separator tank (oil sump). Certified components will be stamped with the ASME U-Stamp and accompanied by the ASME Data Report as legal and compliant documentation.

Q5: How is maintenance and spare parts replacement handled? Does it affect the certification status?

A: Any repair or replacement of pressure-bearing components (e.g., replacing the oil separator tank) must be performed by or under the guidance of an organization or personnel with the appropriate ASME qualifications to ensure compliance is not compromised. We provide professional maintenance services for certified components. Routine maintenance, such as changing filter elements or lubricating oil, does not affect the certification.
