Mycom 200V, Screw compressor, Open

Use this catalogue to identify the spare parts you need to repair your compressor. The OEM catalogue is crossreferenced with our spare parts database, matched items are highlighted. Some of our existing spare parts may not be shown because our database is incomplete (e.g. missing OEM P/N), or because we sell the items separatelly (typical example is the piston-connecting rod assembly). If you have any doubt please ask us.

Compressor description by Ralkin

Introduction: The MYCOM SCV-series is a single-stage screw compressor that utilizes an original O-profile screw lobe design to achieve high efficiency with minimal leakage. This series is designed for economical operation through variable capacity control and offers high reliability via specialized bearings, a bellows-type mechanical seal, and an IP66-grade unloader assembly. The SCV series is versatile, accommodating various rotor diameters, shaft lengths, and discharge directions.

### Model Identification: Since "200V" represents the base size designation rather than a full model string (which would include shaft length, discharge direction, etc.), here is the breakdown of the provided code:

  • 200: Rotor Diameter (200 mm)
  • V: Series Name (SCV-series)

Note: To fully identify a specific unit (e.g., N200VMD-H-X), additional codes for working fluid, rotor length (S/M/L), and discharge direction (D/G) are required.

### Technical Features:

  • High Efficiency: Achieved through an original O-profile screw lobe design that minimizes leakage.
  • Variable Capacity Control: Economical operation with a variable capacity mechanism (10 to 100% actual load).
  • Versatility: Available in four rotor lobe diameters and three shaft lengths, with a mechanism to easily change three ranges of Vi (expansion ratio).
  • Reliability: Utilizes specialized bearings, a bellows-type mechanical seal assembly, and a robust unloader assembly.
  • Low Vibration/Noise: The O-profile rotor design contributes to reduced operational noise and vibration.
  • Refrigerant Compatibility: Compatible with Ammonia, Hydro Fluoro Carbon (HFC), and Propane.

### Specifications & Data: The following specifications apply to the 200V family (encompassing models like 160V, 200V, etc., specifically the 200 mm rotor diameter units):

  • Rotor Diameter: 200 mm
  • Mass (Compressor Alone): 610 kg to 700 kg (depending on shaft length: S, M, or L)
  • Swept Volume (at 2950 min⁻¹): 810 m³/h (Short) to 1210 m³/h (Long)
  • Swept Volume (at 3550 min⁻¹): 975 m³/h (Short) to 1460 m³/h (Long)
  • Gas Inlet Port Size: MYK 150A
  • Gas Outlet Port Size: MYK 125CD
  • Economizer Port Size: MYK 32A
  • Rotation Direction: CCW (viewed from motor)
  • Capacity Control: 10 to 100%
