ScubaTANK WX - WRAS Approved In-tank Booster Set
The revolutionary ScubaTANK WX is a combined break tank and booster set with stainless steel pumps. Quiet, efficient and easy to install.
To calculate the likely peak demand in a boosted cold water system, use the table below, which shows the actual flow requirements for each appliance, and the likely simultaneous demand in low usage applications, normal domestic situations and higher usage commercial systems.
|Low frequency usage||Care homes for elderly persons, offices|
|Domestic frequency usage||Individual private residences, infant schools|
|Commercial frequency usage||Hotels, student accommodation, apartments|
By multiplying the number of appliances by the flow figure in the relevant column, a suggested design flow rate can be established. It is important to note that there are instances where a different column must be used for a particular appliance. A sports club, for example, may need all of the showers running at once, so the figure would be the actual flow requirement multipled by the number of showers installed.
|Qty||Appliance||Actual Flow Requirement (l/s)||Low Frequency Usage (l/s)||Domestic Frequency Usage (l/s)||Commercial Frequency Usage (l/s)||Peak Flow Rate Design Duty|
|Shower (high flow)||0.50||0.040||0.065||0.030|
|Cleaners Sink (H&C)||0.30||0.003||0.005||0.006|
|Domestic Washing Machine||0.20||0.007||0.007||0.010|
|Commercial Washing Machine||0.30||0.020||0.030||0.060|
Important note: When calculating the pressure required, it is critical to allow for the static head and outlet pressure requirements in your calculations.
Once you have worked out the total peak flow rate design duty you can use this information to specify pumping products. If you need to specify a booster set you can use our helpful four step guide - click here.
