Cold Water Booster

 

After much thought and feedback from you, our amazing customers, we decided it was time to add a few more options to our PUK-Vari range of variable speed cold water boosters! We have added two new models to the Variboost and two new models to the Vari-Twin ranges.

 

The Variboost units are variable speed constant pressure booster pumps that have been designed to suit systems that have unvented hot water cylinders with pressure reducing valves and high resistance bathroom fittings that require a balanced pressure on hot and cold supply pipes.

 

The Variboost units have inverters designed for water boosting applications with dry running protection. The units themselves have a 19lit. WRAS approved pressure vessel which allows for smooth cut in and ramp down of the pump. The pumps are also WRAS approved and will suit potable water applications. The new Variboost models comes in two sizes that have been selected to suit most domestic systems:
 

 - PUK Variboost 3/60 with a duty of 1 l/s @ 3 Bar. (1 to 3 Bathrooms)
 - PUK Variboost 3/120 with a duty of 1/s @ 3 Bar. (3 to 5 Bathrooms)

 

PUK Variboost Water Booster 

 

The Vari-Twin units are variable speed constant pressure booster pump sets that have been designed to suit domestic and commercial systems with hot and cold supply pipes. The units are ideally suited for systems with un-vented cylinders and high resistance and flow bath room fittings.

 

The Vari-Twin units have inverters designed for water boosting applications with dry running protection. The units themselves are supplied with 2 x 19lit. WRAS approved pressure vessels which allows for smooth cut in and ramp down of each pump. The pumps are also WRAS approved and have stainless pipe manifolds to suit potable water applications.

 

The Vari-Twin pumps work together via a Bluetooth data connection that allows the pumps to synchronise and alternate duty. The range comes in two sizes that have been selected to suit most domestic systems (Both units will give over 100 l/m which is required for most commercial un-vented hot water cylinders):
 

 - PUK Vari-Twin SM with a duty of 2 l/s @ 3 Bar.
 - PUK Vari-Twin LG with a duty of 4/s @ 3 Bar.

 

PUK Vari-Twin Water Booster

 

Both the Variboost and Vari-Twin units should be connected to an adequately sized break tank so that the out let flow rate will not drain the tank when the system is a full flow. To give a 5 minute storage time the minimum size tank would be:
 

 - Variboost 3/60 = 300lit. (Suggested Size 500lit).
 - Variboost 3/120 = 600lit. (Suggested Size 750lit).
 - Vari-Twin SM = 600lit. (Suggested Size 680lit).
 - Vari-Twin LG = 1200lit. (Suggested Size 1350lit).

 

To cover potable water regulation the tanks will require a raised ball valve chamber so that the tank has the required air gap.
