Plus Turbo

Since 2016, after thorough research and project approval, PlusTurbo has devoted itself to the development of oil-free centrifugal air compressors for fuel cells. This was the company's first independently developed industrialization project. Working together with the Department of Automotive Engineering of Tsinghua University and a team of internationally renowned experts, the company overcame core technical barriers such as high-efficiency low-specific-speed compressors, dynamic pressure air foil bearings, high-speed motors and high-frequency control, and successfully developed the XT-FCC series air foil bearing compressors. The product series fully covers the clean air supply system needs of 30-150kW fuel cell stacks. The official website emphasizes: if the stack is the heart of the fuel cell power system, the oil-free air compressor is its powerful lung and a very important component of the fuel cell system — the 'heart-lung function' largely determines the technical level and performance indicators of the fuel cell. Based on the fact that each fuel cell customer's system design is different, the company planned a unique XT-FCC technical architecture in its series design; on top of the unified underlying technology and design architecture, it offers very flexible scalability and customizability, and can leverage its forward-development capability to work closely with customers to co-develop exclusive customized versions. The key technical features of this series are: a two-stage pressurization aerodynamic layout for wide operating-condition design, and air foil (dynamic pressure air) bearings achieving 100% oil-free operation; the official specification pages uniformly state 'Design: two-stage; Bearings: air foil bearings'.

The official company introduction lists ECC alongside FCC as one of the company's industrialization layout projects: 'Based on the technology mainline of oil-free turbomachinery, and focusing on clean power and clean energy applications, the company has successively laid out projects including the fuel cell oil-free centrifugal air compressor (FCC), the environment control compressor (ECC), air foil bearing high-speed blowers/compressors, compressed air/CO2 dual-working-fluid energy storage systems, carbon capture, utilization and storage (CCUS), and supercritical CO2 (sCO2) turbine generator units.' The Environment Control Compressor (ECC) is the company's high-performance oil-free centrifugal compressor product line for environment control; as a key component of HVAC, refrigeration and other environment control equipment, it delivers oil-free circulating working fluid at specific flow rates and pressure ratios to the system, following the company's air foil (dynamic pressure air) oil-free turbomachinery mainline. The official website currently has no independent ECC product page and no disclosed models.

The official website discloses no numeric parameters for the ECC such as flow rate, pressure ratio, power or rotational speed; only its structural technical basis is stated: 'breakthroughs in core key technologies such as high-performance aerodynamic design, high-power-density high-speed motors and high-frequency electronic control, and automotive-grade dynamic pressure air foil bearings, with independent intellectual property rights', and it is clearly an oil-free centrifugal compressor providing specific flow rates and pressure ratios to systems via oil-free circulating working fluid. To avoid fabrication, no numeric indicators are listed here.

HCC stands for Healthy Control Compressor, the company's clean power gas product line under its oil-free turbomachinery technology mainline, targeting fields requiring 100% clean power gas such as oxygen production, nitrogen production and power gas stations. In public business materials the company also describes HCC as a 'medical intelligent micro oil-free turbine blower', targeting the micro high-speed turbine blower market for medical and home ventilators, using key technologies such as micro high-speed bearings, micro high-speed motors and controllers, and micro high-performance compressors. This family is included per user instruction. Evidence note: HCC and ECC both belong to the company's publicly disclosed division-level businesses (FCC division, ECC division, HCC division, energy storage division), but the current official product center/company introduction pages only list ECC and other product lines in the sentence about 'layout projects' without separately listing HCC; therefore this family does not fabricate an independent product page address, and the sourceUrl points to the company introduction page that discloses the same batch of industrialization layout projects; the description contains no parameters not found in official sources.

The official website does not disclose numeric parameters of the HCC such as models, flow rate, pressure ratio, rotational speed or power; only the structural technical expressions common to the company's oil-free turbomachinery product lines can be used: high-performance aerodynamic design, high-power-density high-speed motors and high-frequency electronic control, and automotive-grade dynamic pressure air foil bearings. To avoid fabrication, no numeric indicators are listed here.

A turbomachinery design and development consulting service for customers working with bladed machinery, covering gas turbines, supercritical CO2 turbines, air-separation and refrigeration centrifugal machines, turbochargers and further machine families. Projects follow the whole chain from cycle to prototype: thermodynamic cycle and performance targets come first, then aerodynamic or hydraulic design of the flow path, with rotor dynamics and structural strength reviewed in parallel, closed out by prototype build and rig validation. Customers need not assemble a full team for a new machine; they receive verifiable design results resting on accumulated experience, which resolves much of the uncertainty of a new programme earlier in the process.
