Ideal for chemical processing, food and beverage, packaging, laboratories, and more.
Utilizes PTFE-filled piston rings and guide rings for completely oil-free lubrication within the compression chamber. Eliminates the risk of oil contamination, ensuring the highest purity of output gas and meeting stringent requirements for food, pharmaceutical, and other high-purity industries.
Features a V-type or W-type block design with a skid-mounted configuration. Compact footprint allows for flexible installation and easy system integration, perfect for space-constrained environments.
Employs 2-stage or 3-stage compression technology to increase pressure progressively and smoothly. Effectively controls the compression ratio per stage and discharge temperature, ensuring long-term reliability and extended service life.
Equipped with a high-efficiency air-cooling system, eliminating the need for complex external water cooling circuits. Reduces installation and operational costs, especially suitable for areas with limited water resources.
Includes automatic shutdown for overpressure protection, motor overload protection, and other smart safety features. Ensures equipment and process safety, with support for remote monitoring and automation integration.
Optimized drive system and low-friction components significantly reduce shaft power and energy consumption, enabling cost-effective continuous operation.
