Product overview

AZ1 and AZP1 are air-cooled screw equipment families with separate RCUF cooling-only and RHUF heat-pump selections. AZ1 has 18 listed sizes and AZP1 has 17, with model-specific differences in duty, circuit arrangement, dimensions and weight. Compare the four tables at their stated cooling or heating conditions. A shared size code does not establish the same cooling output for a chiller and its heat-pump variant.

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.

AZ1 / RCUF — cooling-only performance

Semi-hermetic twin-screw, fixed-speed air-cooled chillers.

Key configuration options

  • RCUF references provide cooling duty; RHUF references have separately stated cooling and heating ratings. Heating COP is not calculated where the table does not print it.
  • R134a, semi-hermetic twin-screw compressors. Multi-section unit arrangements retain their source circuit and section-weight notation.
  • Water connection, installation length and lifting / access requirements depend on the complete model and assembly.
  • Manufacturer reference: AZ1 / AZP1 brochure, print code Z0050004-260914. RHUF200AZ1 net weight awaits manufacturer clarification.

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.
