•Ensure facility managers understand the additional load being added to the chilled water supply of the building. Be aware that the added heat load might affect other components being cooled by the chilled water plant.
Plumbing materials to avoid
Do not use the following materials in a closed water system:
•Oxidizing biocides
•Aluminum components
•Brass components with high levels of zinc
•
Condensation management
Any condensation that forms is collected in each individual cooling module and is taken through a discharge tube to a condensation tray integrated in the base assembly. Where multiple cooling modules are used, the condensate discharge tubes are connected to one another using quick connectors. Any condensation that occurs is then removed through this series of connections to the condensation tray.
When the specified condensation level in the condensation tray is reached, a sensor activates a pump that pumps the condensation into the return system. A further discharge tube runs out of the system from condensation tray to drain excess fluid if needed. This hose should be connected to a collection system or an external drain.
To ensure reliable drainage:
•Ensure no kinks form in the drainage hose.
•Do not reduce diameter of drainage hose.
•Route the drainage hoses so that they always run downhill.
To avoid excessive buildup of condensate and to conserve energy, consider raising the cooling water temperature to the necessary cooling capacity.
