We do not supply TXVs with our DX Coils. We have distributor model numbers that are utilized to purchase a TXV at your local supplier.

The difference between a face split coil and an intertwined coil is the ability to condition the entire air stream while utilizing the individual circuits. A face split circuit is a horizontal split across the fin length that can be designed for 50/50 capacity split or varying percentages. This means that if only one circuit is running you will have non conditioned air mixing with conditioned air. Intertwined circuits allow full conditioning of the air stream with independent circuits be utilized.

Yes, we need to know the refrigerant so that we can properly design the coil. If we are duplicating a DX coil, we need to know the refrigerant and specify the correct nozzle size for proper operation.
