Dunham-Bush System LST low surface temperature radiators deliver efficient ambient heating in applications
where safety is paramount. The hot central heating pipes and heat emitter are totally enclosed within the robust
steel casing.
The clever casing design permits secure key access for cleaning while TRV control valves can be selected for
external or internal (tamperproof) functionality.
By applying test results through a mathematical model, Dunham-Bush engineers have developed a Selection
Program to help the heating designer optimise their radiator schedules for all conceivable LPHW conditions.
BSRIA tested to BS EN 442 heating performance and NHS Guidance touch temperatures, System LST is a
complete solution for safe efficient heating.
FEATURES
The Dunham-Bush System LST radiators comprise:
- mild steel casing (stove finish to RAL 9010 white)
- extruded aluminium grilles (pencil proof)
- zinc coated steel backplate (heat reflective)
- integral emitter brackets
- choice of Element or Panel emitters
- stock or custom RAL and BS colour finishes - available to order.
BENEFITS
√ NHS guidance compliance by design and test
√ Optimum heating by natural convection
√ Selection program for all LPHW flow/return conditions
√ 1st and 2nd fix deliveries
√ Rapid cost effective installation
√ No special tools or fasteners required
√ Pencil proof 'closure-lock' grilles (no screws)
√ Reflective backplate to enhance heating efficiency
√ Compatible with all makes of TRV and LSV
√ Lockable access panels
√ Easy access for cleaning
√ BS EN 442 verfied heat outputs
Style A - for 'wet floor' areas, or simply where casings are better sited above skirting.
Style B – for 'wet floor' or 'dry floor' areas where pipes approach from below or through walls.
Style C – for 'dry floor' areas where the robust floor plinth also provides extra space for pipe runs.
Style D – vertical casings delivering high performance from confined spaces.
Element emitters– E11, E21, E12, E22, E23 – low water content Cu/Al for unrivalled heating performance and
rapid response TRV control, saving energy. Suitable for 2-pipe systems.
Panels emitters – P31, P41, P61, P32, P42, P62, P72 – traditional steel panel design delivering excellent output for
2-pipe and 1-pipe systems.
TEST AND WORKING PRESSURES/TEMPERATURES
All emitters shall be suitable for maximum cold test pressure of 10.5 barg and maximum working pressure of
8.0 barg.
Radiator emitters shall be limited to a maximum working temperature of 95°C. Element emitters shall be limited to a
maximum working temperature of 110°C.
Automatic airvents maximum cold test pressure is 8.5 barg; maximum working pressure 8.5 barg @ 11/°C.
Manual airvents maximum cold test pressure is 10.5 bar, maximum working pressure 6.0 bar @ 110°C.
System test and working pressures/temperatures shall be adjusted should fittings and valves supplied by others
have test or service conditions lower than above.
