Equipment selection guide
Prepare the selection brief
Confirm the interfaces
Agree piping or service connections, electrical supply, control interfaces, installation access and the routine cleaning method.
Agree the scope
Specify the included equipment, optional configurations, commissioning tasks, acceptance conditions and documentation required.
Operating principle
How it works
An inverter adjusts compressor speed to match demand. Outdoor air exchange, water-side heat transfer and defrost control operate together within the selected machine’s envelope.
Technical approach
Key considerations
- A full DC variable-frequency low-temperature air-source unit is documented.
- Variable-speed scroll compressor and vapour injection are described.
- The nominal NXFR-C schedule on another brochure page must not be assumed to rate this separate inverter configuration.
Questions & answers
How is the final model selected?
Provide the design duty, water or air conditions and seasonal operating points. The technical offer must establish the selected model, available capacity and electrical input at those conditions.
What options are included as standard?
Materials, controls, interfaces and accessories are confirmed in the technical offer. Illustrated equipment and optional functions are not automatically included.
Can this equipment be integrated into an existing site?
A retrofit review needs the existing hydraulic layout, utilities, available space and operating constraints. Provide photographs and current operating data with your enquiry.
