Lowara Resfix Fixed speed Domestic Booster Set

The Resvari (variable speed) and Resfix (fixed speed) booster sets have been designed to be compact, quiet in operation and to make servicing as simple as possible. Both variable and fix speed booster sets use a common cabinet size which have a removable top section. On routine maintenance checks or the rare occasion when the unit may need attention the top section can be easily removed to expose all the components which will help to make servicing quick, clean and problem free. Assist unit
Where a larger water storage volume is required an assist unit can be added to give an additional 180 litres of water storage.

Duty Requirement

The duty required can be found by looking at the two following items:-

  1. Pressure requirement. This has 3 elements to consider:- 
  • a. Static head. This is the height above the break tank water line in the booster set to the highest outlet.
  • b. Friction loss These are the losses through the pipe work including bends.  In the example below, estimating the total length of pipe to be 25 metres and limiting the velocity to 1.5m/s an average pressure loss of 15 metres per 100 metres can be expected.
  • c. Residual pressure, this is the pressure required at the outlet.
  • Example: Static height = 4m, Friction loss = 15/100 x 25m = 3.75m, Residual pressure at highest outlet = 20m, Total pressure requirement = 4 + 3.75 + 20 = 27.75m/10.2 = 2.7bar
  1. 2. Flow requirement. The flow requirement will depend on the number of occupants and the number and type of outlets that will be served. In general the Resvari (variable speed) and Resfix (fixed speed) booster sets are suitable for dwellings with up to 4 occupants or 6 occupants with the addition of the assist unit.
