Technical documents
Ordering and delivery
Compressor orders are reviewed against voltage and application details. Lead time is confirmed with the order or quotation. Freight is based on the packed consignment; large or configured products receive a confirmed pack plan before dispatch.
SYSTEM BUILDER
What else do I need?
Choose the route that matches your project. The compressor can replace a compatible unit, power a custom split system, or form part of a complete package.
Connect to existing A/C
Use the existing condenser, evaporator and controls only after confirming capacity, R134a compatibility, oil management, pressure protection and electrical load.
Build a new split system
Add the matched heat exchangers, protection, controls, hoses and mounting hardware shown below.
Choose a complete kit
If you do not want to engineer every component, start with a packaged system sized for the cabin and duty cycle.

Final system design: A qualified automotive A/C technician must confirm refrigerant charge, TX valve, hose routing, oil balance, pressure settings and electrical cable/fuse sizing.
CHOOSE THE INSTALLATION ROUTE
Adding A/C or retaining the factory circuit?
Use the new-system guide when the vehicle has no A/C. Use the existing-circuit guide when retaining compatible factory heat exchangers and controls.
