How much desiccant is recommended for a proper dry lay-up per 1,000 gallons of cold water capacity?

For a proper dry lay-up of a system with cold water capacity, a recommendation of 16 pounds of desiccant per 1,000 gallons is based on ensuring sufficient moisture control within the system. Desiccants are used to reduce humidity and prevent damage from corrosion during periods when the system is not in operation.

Choosing 16 pounds is appropriate because it provides an effective balance that adequately absorbs moisture without being excessive, which could lead to depletion of the desiccant too quickly or unnecessary costs. The selected amount is aligned with industry practices that emphasize both protection of the equipment and cost-effectiveness while ensuring that all areas of the system are covered adequately.

In contrast, the other options provide either insufficient or excessive amounts of desiccant, which could result in ineffective drying or wastage. Therefore, 16 pounds stands out as the optimal choice for a typical dry lay-up process.
