Rt40 PI-RTLV
Creating free energy
Towel rails typically only provide a small amount of heat, and when towels are placed over the rails, they will effectively insulate the rail surfaces, further reducing heat output and raising return temperatures.
Recommended by CP1 (2020) as best practice, installing a Pressure Independent Return Temperature Limiter (PI-RTLV) on the towel rail (as opposed to the collective space heating return) guarantees low return temperatures from the towel rail without compromising function.
Rt40 PI-RTLV Configurator
All our Rt40 Pressure Independent RTLV sets are bespoke to the specific building requirements. To help you choose the correct towel rail valve set you can use the configurator.
This will take you methodically through the selection process, with pictures of each component, info buttons to let you know when and what component to choose, as well as an automated product code generator.
The use of a return temperature limiter on heated towel rails is particularly useful as the output (and hence return temperature) is otherwise determined by the number of towels

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 Rt40 can permanently and reliably control the heat delivered to individual towel rails.
40°C Maximum
Return temperature limiting
Protect the network’s performance without compromising the comfort of occupants.
