Product overview

WZP and WZX are R134a water-cooled twin-screw chiller selections in the reviewed brochure. Each model retains its own capacity, input power, COP, dimensions and weight. They are distinct from the inverter-driven WV / WVP family.

Key technical specifications

WZP: RCUF R134a references

Water-cooled twin-screw WZP models; no inverter drive is inferred. The similarly sized 150/156, 200/211 and later references have distinct input, dimensions and weight.

  • Cooling rating: chilled-water leaving temperature 7 °C; condenser-water entering temperature 30 °C; chilled/condenser-water flow rates 0.172 / 0.215 m³/(h·kW). These are the stated selection conditions, not a generic 12/7 °C rating.
  • RT and kW are copied independently from the source, not converted. COP is the stated rating under the table's selection conditions.
  • Main supply: 380 V / 3 phase / 50 Hz; control supply: 220 V / 1 phase / 50 Hz. Chilled-water leaving range: 5–20 °C for RCUF50–130WZP; 4–15 °C for RCUF150–521WZP. Condenser-water leaving: 22–40 °C.
  • Brochure reference ratings are not a current stock or delivery guarantee. Confirm the complete configuration, nameplate, destination-market requirements and current selection before procurement.

Key configuration options

  • WZP and WZX are separate technical selections; similar size codes do not mean identical ratings.
  • Condenser-water conditions, pressure rating, heat recovery and water-box options require project selection.

Applications

  • Central chilled-water plants with condenser-water systems
  • Project-specific water-cooled equipment supply

Information for equipment selection

  • Complete model / configuration and equipment schedule
  • Required duty and design water / ambient conditions
  • Power supply, installation space and project location
  • Destination-market requirements and current availability confirmation

Application suitability requires a review of the project requirements and selected model.
