Pt40 Pressure Independent Thermostatic Radiator
Valve (PI-TRV)

Creating free energy

Maintaining a low return temperature at all loads minimises energy waste, which results in a cost effective heat delivery. To achieve this requires pressure independent flow control that dynamically balances the heating system.

Originally designed for the retro-fit market to reduce the operating costs of unbalanced buildings. The Pt40 (PI-TRV) balances the heating system 24 hours a day, 365 days a year.

Economy

Minimise waste, maximise efficiency

From reducing energy waste, improving the efficiency of the heat plant, lowering heating bills and reducing set-up & commissioning time, the Pt40 offers 12-15% energy saving compared with traditional TRVs.

Best practice

Pressure independent

Pressure fluctuations due to varying load conditions require a constant automatic balancing to maintain a comfortable and efficient heating system.

Pre-settable

No more no less

With a simple setting scale (1-7), the Pt40 can permanently and relia­bly control the heat delivered to individual rooms.

Performance

Fastest reaction time

The RA2000 gas sensor is the fastest reacting TRV available. This results in additional energy savings of 5-8% when compared with liquid-filled thermostatic sensor heads.
