well ive got a love hate with chilled water-condenser loops. Most units in md the building is responsible for the loop well if they do work or the loop goes down your kinda in a bad spot. but for the units them self are fantastic. we have some of the first mini-mates on some of our plans and for the most part are still great units ( building loop) but anyway i will deff stay where im at for awhile. Id really like to learn about chillers too.
