Spiral: Circuit B Small cross-section circuit for low flows and/or lower viscous fluids 11. Mounting All applications and Vapour Condensing in Circuit B Eliminates trapped air Both circuits will drain When used as an evaporator, pipe evaporating liquid in at the bottom When used to condense vapour in Circuit B, pipe vapour in at top Liquid to Liquid Applications Air is removed by pumping the liquid Both circuits will not drain Circuit A connection must be positioned at the top Vapour Condensing in Circuit A Except Type CC Air in Circuit B is removed by pumping the liquid Circuit B will not drain Can be mounted at any angle but Circuit A connection must be at the bottom 12. Piping All standard connections are tapered pipe thread. Refer to model data for connection size. Pipe the heat exchanger for counter flow fluid direction. This arrangement with the fluids flowing in opposite direction is recommended for most heat transfer applications. Page 8 of 8
