Product overview

AZ2, AZP2 and AZX are R134a air-cooled screw equipment selections, each with 12 listed sizes and separate RCUF and RHUF references. The subseries retain their own input power, COP, seasonal index, dimensions and weights. RHUF heating ratings are shown at their separate test point. These tables describe the conventional screw configurations in this brochure and are independent of the inverter-driven AVX series.

Key technical specifications

Match the complete model and configuration to your design duty. Compare ratings only at the stated water and ambient conditions; then send the model reference, quantity and project requirements for review.

Scroll each table horizontally to compare all columns. Model references remain visible as you scroll.

AZ2 / RCUF — cooling-only performance

Fixed-speed semi-hermetic twin-screw chillers. RCUF and RHUF are separate model selections.

Key configuration options

  • Choose the subseries and cooling-only RCUF or heat-pump RHUF configuration before comparing performance.
  • Semi-hermetic twin-screw compressors with star-delta starting. Source main supply is 380 V / 3 phase / 50 Hz; control supply is 220 V / 1 phase / 50 Hz.
  • AZX 180 and 200 references use a flooded water-side heat exchanger; the other listed AZX sizes use the separate dry-expansion arrangement. Do not generalize one construction to every size.
  • Manufacturer reference: AZ2 / AZP2 / AZX brochure, print code Z0050044-260608. RCUF600AZP2 cooling capacity awaits manufacturer clarification; its other printed values remain listed.

Applications

  • Outdoor chilled-water systems for commercial and industrial projects.
  • Cooling and, for the listed RHUF models, heating equipment selected for the project's design conditions.

Information for equipment selection

  • RCUF cooling-only or RHUF heat-pump duty, complete model reference and quantity.
  • Cooling and heating loads, water temperatures / flow and design outdoor dry-bulb / wet-bulb conditions.
  • Power supply, outdoor installation space, access and water-side design pressure.
  • Equipment schedule or BOQ, destination country and requested delivery date.

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