Coolant Storage Tank Capacity Selection
Choosing the right capacity for a coolant storage tank depends on several key factors, starting with the requirements of the connected equipment. Calculate the total coolant volume needed by checking the manufacturer's specifications for the machinery it serves—e.g., CNC machines, engines, or industrial coolers.
Capacity Calculation Rule
A general rule is to select a tank that holds 1.5–2 times the system's total coolant capacity to accommodate expansion, especially in high-temperature operations where fluid expands.
Key considerations for tank sizing:
- Usage frequency: Continuous production lines need 500L+ tanks, while intermittent workshops may use 50–200L
- Coolant lifespan: Match 2–3 replacement cycles if coolant changes frequently (every 3–6 months)
- Space constraints: Vertical tanks save floor space; horizontal suits large capacities
- Auxiliary systems: Account for extra volume if using built-in filtration or mixing
- Climate factors: Cold regions may need larger tanks to prevent freeze-thaw issues
Always reference the equipment's operating manual and consult with suppliers to balance capacity with practicality, avoiding undersized tanks that risk system damage or oversized ones that waste space and increase costs.
