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-driven centrifugal compressor circulates refrigerant; magnetic bearings support the rotor without the conventional oil-lubricated bearing arrangement. The selected machine must be checked against lift, turndown and water temperatures.
Technical approach
Key considerations
- Magnetic-bearing centrifugal machines are explicitly included in the supplied company brochure.
- Direct-drive and oil-free operation are described.
- Evaluate part-load and full-load performance at matched conditions.
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.
