■ Drift rate varies with design water loading and air rate, as well as drift
eliminator depth and number of directional changes. The indicated
rate of 0.005% is easily achievable without premium cost. If a lower
rate is required, please discuss with your Marley sales representative.
■ The combination of PVC piping and polypropylene nozzles is very
resistant to the build-up of scale and slime.
■ The MC fluid cooler design offers side-suction as standard. Bottom
outlets may be supplied to accommodate a variety of piping schemes.
Unless so specified, the fluid cooler you may be asked to approve
may only be available with one type of suction connection requiring
you to redesign your piping layout.
The sloping floor and low-level drain is valuable because it provides a
way to achieve flush-out cleanability.
