Product Features

Ultra-high energy efficiency, Low noise, Low vibration, High reliability

■The new generation of two-stage compressor units created by the North American R&D Center is designed to achieve optimal efficiency.

■The entire series uses more than 60 main units and has obtained many domestic and foreign patents.

■The entire series of products complies with the latest "GB19153-2019" standard, and units below 355KW all achieve first-level energy efficiency.

Two-stage compression screw host

Two-stage compression achieves reasonable pressure distribution, reduces compression ratio, reduces internal leakage, and improves volumetric efficiency;

Two-stage compression reduces bearing load, increases bearing life, and extends main engine life; The patented "Y" series profile screw rotor has an efficiency 5~15% higher than other profiles.

High-end configuration and system optimization

KRSP2 two-stage compression has high-end configuration and system optimization in product layout design and details. The efficient host and inherent air intake adjustment design, cooling smooth design, oil-gas separation technology, high-efficiency motor, intelligent automatic control and other innovative technologies make the efficiency reach the industry leading level.

High-quality components

Optimized cooling system

The cooling system is designed based on an ambient temperature of 46°C. The screw compressor special coolant is used to provide good lubrication and cooling services for the compressor, with a designed service life of 8,000 hours.

The fan blades of the cooling fan are optimized to reduce noise while maintaining efficiency. The reasonable smooth design inside the chassis provides good cooling for the electrical and motor parts and maintains a suitable temperature inside the chassis.

The upper exhaust design makes it easy for users to install the exhaust duct. The 75~250kW air-cooled unit uses a variable frequency centrifugal fan, which is quieter and more energy-saving.

High efficiency intake valve

■Large diameter, low pressure drop

■Improve the stability of the system

■Ensure effective regulation and control of flow during driving, operation and shutdown

■ Long-closed intake valve to reduce startup load

High-precision filtration and oil separation system

Professionally customized high-precision heavy-duty nano-material air filter, with a filtration accuracy of 99.9%@3μm, effectively protects the host and bearings. The lubricating oil filter has an accuracy of 99.9%@10μm, providing clean lubricating oil for the compressor host.

High-efficiency oil separation system, tangential air intake, built-in baffle, under the action of centrifugal force, gravity, and impact, most of the oil droplets have been separated, and after the polymerization filtration of the oil separation core, the exhaust oil content is less than 3ppm.

Coolant sampling valve

The unit is designed with a sampling valve to facilitate users to collect oil samples for quality testing.
