Just seeing if anyone can advise me on a suitable size outdoor unit for a cellar cooling system. Suppliers aren't willing to match and are insisting on a full new system. Usually I would but the customer Is looking to close the business in the next 12 month so trying to keep the cost down for him.

It's a cellar cooling which needs a new outdoor unit.
The evaporator is a single fan Kobol CR-39.Currently on R404A.
The cellar is below ground, Pipe run is around 5 metres.
Cellar size is 5m x 6m x 2.5m high.

Any advice will be much appreciated. Thanks
