Xiteliduo refrigeration compressor portfolio covers small 4-cylinder, medium 4-cylinder, large 4-cylinder, large 6-cylinder reciprocating refrigeration compressor, single-unit two-stage refrigeration compressor, cascade refrigeration unit and screw refrigeration compressor.
The single-stage piston reciprocating refrigeration compressor series covers cooling capacity from 25kW up to 480kW, designed for evaporation temperature down to -25℃ for cold storage and food processing.
Single-unit two-stage refrigeration compressor serves evaporation temperature from -40℃ to -70℃, built for deep-freezing applications such as chemical processing and material testing.
Cascade refrigeration unit extends cooling capacity to temperatures as low as -120℃ by adopting two independent refrigerant circuits with separate high-stage and low-stage compressors.
Screw refrigeration compressor targets large stable refrigeration loads above 320kW, suitable for 24-hour continuous operation for ice factories and large-scale logistics cold storage.
xiteliduo reciprocating compressor single-stage piston series uses cast iron cylinder blocks and silicon-aluminum alloy pistons with reliable spring-loaded suction and discharge valve plates.
Single-unit two-stage refrigeration compressor adopts reinforced cylinder structure and interstage cooling design to control discharge temperature under ultra-low evaporation working conditions.
Cascade refrigeration unit can be configured with xiteliduo piston compressor for low-stage circuit and screw refrigeration compressor for high-stage circuit to balance performance and cost.
Screw refrigeration compressor is equipped with twin alloy rotors and oil injection cooling, with slide valve to realize stepless capacity regulation across 10%~100% load range.
All product lines support optional explosion-proof modification to Ex d II BT4 grade for chemical, pharmaceutical and hazardous workshop refrigeration scenarios.
Single-stage reciprocating refrigeration compressor models: small 4-cylinder, medium 4-cylinder, large 4-cylinder, large 6-cylinder, share many common spare parts to simplify maintenance management.
Valve plate overhaul cycles for single-stage piston compressors vary from 6500 to 7500 working hours, while single-unit two-stage reaches 6000 hours.
Cascade refrigeration unit piston side overhaul cycle is 5500 working hours; screw refrigeration compressor bearing overhaul cycle can reach up to 12000 working hours.
Recommended refrigeration oil differs across series: single-stage piston ISO VG68; single-unit two-stage and cascade low stage ISO VG100; screw refrigeration compressor ISO VG68 with NAS6 requirement.
Noise level at 1m: small 4-cylinder 80dB(A), medium 4-cylinder 81dB(A), large 4-cylinder 82dB(A), large 6-cylinder 83dB(A), single-unit two-stage 84dB(A), cascade 85dB(A), screw 81dB(A).
Annual maintenance downtime differs by equipment type. Single-stage piston 3.4~3.7%, single-unit two-stage 3.8%, cascade refrigeration unit 4.0%, screw refrigeration compressor 2.9%.
Annual maintenance cost ratio: small 4-cylinder 3.0%, medium 4-cylinder 3.1%, large 4-cylinder 3.2%, large 6-cylinder 3.3%, single-unit two-stage 3.6%, cascade 4.2%, screw 4.1%.
All models adopt Class F motor insulation, with built-in temperature protection, high and low pressure protection, oil differential pressure protection and liquid return protection.
Safety relief valves are installed on every compressor or circuit, with mandatory annual calibration to guarantee fast response under sudden pressure surges.
Transport tilt limits: single-stage piston ≤15°, single-unit two-stage ≤12°, cascade refrigeration unit ≤10°, screw refrigeration compressor ≤10°.
The product portfolio covers the full spectrum of industrial refrigeration requirements: small cold storage, medium process cooling, large logistics cold storage, deep freezing and cryogenic applications.
For procurement engineers, cooling capacity, evaporation temperature, load fluctuation and operating hours are the four core parameters to select the correct compressor model.
For medium-small loads and -25℃ and above evaporation temperature, small or medium 4-cylinder reciprocating refrigeration compressor is usually the optimal choice.
For large fluctuating loads at -25℃ and above, large 4-cylinder or large 6-cylinder reciprocating refrigeration compressor is recommended.
For large stable continuous loads above 320kW, screw refrigeration compressor delivers better energy efficiency over long-term operation.
For deep freezing from -40℃ to -70℃, single-unit two-stage refrigeration compressor is preferred with lower investment than cascade refrigeration unit.
For cryogenic cooling below -70℃ down to -120℃, cascade refrigeration unit with dual independent refrigerant circuits is the required solution.
System designers also evaluate site ambient temperature, available power supply, floor space, maintenance capacity and budget when selecting xiteliduo refrigeration compressors.
All equipment requires scheduled filter inspection, oil analysis, sensor calibration and leakage testing to keep long-term stable operation and extend service life.
For long idle storage over 6 months, oil change and nitrogen sealing protection are required for all xiteliduo refrigeration compressor models to prevent internal corrosion.
