Product overview

AVX uses R134a and inverter-driven semi-hermetic twin-screw compressors. Cooling-only RCUF and heat-pump RHUF ratings are kept in separate tables. Standard, all-year and heat-recovery selections require confirmation of the complete model and design conditions.

Cooling: leaving water 7 °C; water flow 0.172 m³/(h·kW); outdoor air 35 °C dry bulb. Published COP is kept per model.
Main supply is the brochure's 380 V / 3 phase / 50 Hz or 415 V / 3 phase / 50 Hz option, not a guarantee of both on one unit or 60 Hz availability.
Standard cooling envelope: leaving water 5–20 °C, outdoor dry bulb 5–50 °C. Heat-pump heating envelope: leaving water 35–60 °C, outdoor dry bulb −10–21 °C. All-year options have a separate envelope; extreme conditions can limit duty.
Brochure reference ratings are not a current stock or delivery guarantee. Confirm the complete configuration, nameplate, destination-market requirements and current selection before procurement.

Cooling: leaving water 7 °C; water flow 0.172 m³/(h·kW); outdoor air 35 °C dry bulb. Published COP is kept per model.
Heating: leaving water 45 °C; water flow 0.172 m³/(h·kW); outdoor air 7 °C dry bulb / 6 °C wet bulb. These conditions differ from low-temperature G-series ratings.
Main supply is the brochure's 380 V / 3 phase / 50 Hz or 415 V / 3 phase / 50 Hz option, not a guarantee of both on one unit or 60 Hz availability.
Standard cooling envelope: leaving water 5–20 °C, outdoor dry bulb 5–50 °C. Heat-pump heating envelope: leaving water 35–60 °C, outdoor dry bulb −10–21 °C. All-year options have a separate envelope; extreme conditions can limit duty.
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

Standard cooling-only and heat-pump models are separate selections.
N all-year and heat-recovery configurations require model-specific confirmation; 50 Hz brochure ratings do not establish 60 Hz availability.

Applications

Central chilled-water systems
Project cooling / heating equipment selection subject to design conditions

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.
