Air Handler Cross Post

am looking for our ideal air handler. we are doing hydronic heated/chilled water with it (so no short cycling/freeze concerns) but if I have to size coils separately that's fine.



Looking for a unit with the following specs



1. ECM motor

2. Modulates on static pressure/torque only, not to airflow. 0.5 in WCG preferred, adjustable is great.

3. low or no minimum speed on the fan

4. adjustable airflow rates beyond a +/- 10%, at the very least on a continuous operation setting. so if I'd like a 50 CFM continuous, I'd like to be able to dial that in. Certainly want to get to less than 100 CFM there anyway.



There anything like that out there? sure would be nice to be able to dehumidify without doing much cooling, and would be even better to allow zoning without bypass/dumping.
