With sufficient coolant flow and temps it would be possible to just put that wort chiller inline between mash tun and fermenter and do a single pass. Another option is to recirculate the wort back into the mash tun until the exiting wort is at the correct temp and then redirect into the fermenter.
My answer was in response to the original question. ASD standard sizes include 150 gallon and 300 gallon systems. For 150 and smaller we find that the mash tun jackets provide enough surface area to cool quickly. For 300 gallon and larger that isn't the case and so we recommend the wort chiller pictured.
