Regarding your previous post:
“…I'm getting a quote for the 5 ton challenger unit that can be adjusted to run at 3 tons and increased if I need more. If it's not soooo much more, I'm going for it”
It sounds as though the 5 ton Challenger has a DBV rated at 2.0 tons, giving you a net 3.0 tons of cooling when the DBV is fully opened. Just make sure it is equipped with an anti-short cycling relay. Good luck……..once again friend.
