Low Surface Temperature Collection
Safety Series Low Surface Temperature Collection 16970_Stelrad Radiator Book 2015_Layout 1 23/04/2015 15:34 Page 36 LST Range Standard Stelrad’s range of Low Surface Temperature radiators is the most comprehensive in the UK, with sizes and models to suit all applications. They all meet NHS Guidance for ‘safe hot water and surface temperature’ and are finished with antibacterial paint as standard, making them the No.1 choice for safety-critical environments. Installation is simple and all components are included in a single robust pack.

The complete choice Stelrad LST range offers you the flexibility you need The first coat of paint is applied by electrophoresis and the radiator is then stoved and cooled • The LST Standard leaves you free to specify your preferred controls • Followed by a second powder coat in warm white, the emitter then goes through a final curing stage. It is then allowed to cool prior to packaging • The LST Plus and LST i Plus offer an integral remote sensing thermostat valve, the highly specified Danfoss RAS-D Remote Sensor • All exposed painted surfaces are finished in a long lasting anti-bacterial coating • The LST Vertical is ideal where space is at a premium LST i Plus • An arthritic adaptor is supplied as standard for less able environments - along with a lockshield valve which can only be adjusted with a 6mm Allen key, hidden with a neat metal dust cover to discourage unauthorised tampering. (excludes LST Standard) Remote sensing thermostatic valve The complete package • Special tools are not required, as the valve is gland seal removable • Every Stelrad LST radiator is supplied with an attractive, flat panel outer casing, which is totally reversible to allow piping flexibility • Simple and quick to install, the casing is held by security fittings with a unique seam fixing bracket system to prevent unauthorised access to the emitter accommodated inside • For added protection, the smooth surface is coated in anti-bacterial paint • The emitter provides high outputs through convection for outstanding heating performance • Controlled independent laboratory testing ensures that each emitter is guaranteed to perform to a maximum working pressure of 116 psi (8 bar) and conform to BS EN 442, the European Standard for radiators • The Danfoss RAS-D Remote Sensor is designed specifically for commercial heating systems and can be pre-set to allow adjustment of room temperature between 5°C and 26°C • Suitable for both 1⁄2" steel and 15mm copper piping, with left or right hand, same end connections for flow and return, gives flexibility of installation Lockshield valve • Able to withstand 10 bar static pressure, the valve has a drain tap adaptor available, which can also be used as a filling point • Mandatory fittings should be used in order to comply with current water regulations Connections • 2 x 1⁄2" connections as standard, complete with Danfoss remote sensing thermostatic radiator valve, pre-piped with 2 x 1⁄2" BSP connections at 50mm centres positioned at either left or right of the casing • All specified components required supplied in one robust package Anti-bacterial paint • Every LST emitter is subjected to a multi-stage cleaning process before the paint is applied. This involves several rinsing stages, including an iron phosphate and demineralisation phase CP BIM For further information and advice call 0844 543 6200 16970_Stelrad Radiator Book 2015_Layout 1 23/04/2015 15:35 Page 128 LST Standard, LST i Plus & LST Vertical temperature table For systems not operating at ∆t50 the factors in the table below should be applied. The output of a given radiator can be obtained by multiplying the quoted ∆t50 output by the operating factor. Conversely, to derive a non ∆t50 output, divide the heat output required by the relevant operation factor. This ‘∆t50 equivalent output’ can then be used to select a radiator from the standard tables. ∆t °C Operating Factor ∆t °F Operating Factor 5 0.050 10 0.057 10 0.123 20 0.142 15 0.209 30 0.240 20 0.304 40 0.348 25 0.406 50 0.466 30 0.515 60 0.590 35 0.629 70 0.721 40 0.748 80 0.858 45 0.872 90 1.000 50 1.000 100 1.147 55 1.132 110 1.298 60 1.267 120 1.454 65 1.406 130 1.613 70 1.549 150 1.776 75 1.694 - - Example: Exact output at ∆t50 = 2000 Btu/hr Output at ∆t30 = 2000 x 0.515 = 1030 Btu/hr Average coefficient of 130 is used in the example above Testing and operating pressures All models are high pressure tested to withstand 152.3 psi (10.5 bar). Strictly controlled independent laboratory testing ensures that all Stelrad radiators are guaranteed to perform to a maximum working pressure of 116 psi (8 bar) at a maximum temperature of 95°C. All conform to BS EN 442 - the European Standard for radiators. Caution To ensure that the emitter complies with all aspects of the NHS guidance for “Safe hot water and surface temperature”, Stelrad recommends that a maximum flow temperature of 80° be used with a 20° drop across the system. When designing for domestic systems we recommend that the Stelrad LST range be used only in heating systems complying with the British Standard Code of Practice for Central Heating for Domestic Premises BS EN 12828:2003 and BS EN 12831:2003. Single feed, indirect cylinders are not recommended as should interchange of water occur, fresh aerated water would enter the heating system, resulting in corrosion. Water treatment On completion of the installation, the system should be properly flushed and filled in accordance with the British Standard Code of Practice BS 7593:2006 for the Treatment of Water in Domestic Hot Water Central Heating Systems, Part L of Building Regulations and Good Practice Guidance for Scotland. After installation of a new Stelrad radiator the central heating system should be cleaned and flushed with cleaner to remove existing contaminants, flux residue and other installation debris which, if left, can cause damage to the new radiator. Afterwards, treat the system with an inhibitor to ensure long term protection against corrosion and limescale. A comprehensive range of quality chemicals including inhibitors, cleaners, leak sealers and noise reducers that protect and maintain central heating systems can be obtained from: Sentinel Performance Solutions Ltd The Heath Business & Technical Park, Runcorn, Cheshire WA7 4QX Tel: 01928 588 330 (UK) www.sentinel-solutions.net Fernox - Cookson Electronics, Forsyth Road, Sheerwater, Woking, Surrey GU21 5RZ www.fernox.com Pressure drops 16970_Stelrad Radiator Book 2015_Layout 1 23/04/2015 15:35 Page 129 Stelrad LST Range Standard K1 50 Δt (75/65/20°C) Casing Height 500 650 800 Casing Length mm Emitter Height mm Emitter Length mm UIN 560 760 960 1160 1360 1560 1760 1960 560 760 960 1160 1360 1560 1760 1960 560 760 960 1160 1360 1560 1760 1960 300 300 300 300 300 300 300 300 450 450 450 450 450 450 450 450 600 600 600 600 600 600 600 600 400 600 800 1000 1200 1400 1600 1800 400 600 800 1000 1200 1400 1600 1800 400 600 800 1000 1200 1400 1600 1800 145000 145001 145002 145003 145004 145005 145006 145007 145024 145025 145026 145027 145028 145029 145030 145031 145048 145049 145050 145051 145052 145053 145054 145055 P+ Heat output Watts Btu/hr 1 196 293 391 489 587 685 782 880 290 435 580 725 870 1015 1160 1305 365 548 730 913 1096 1278 1461 1643 145008 145009 145010 145011 145012 145013 145014 145015 145032 145033 145034 145035 145036 145037 145038 145039 145056 145057 145058 145059 145060 145061 145062 145063 669 1000 1334 1668 2003 2337 2668 3003 989 1484 1979 2474 2968 3463 3958 4453 1245 1870 2493 3115 3740 4361 4985 5606 UIN K2 Heat output Watts Btu/hr 284 426 568 710 852 994 1136 1278 386 580 773 966 1159 1352 1546 1739 501 751 1002 1252 1502 1753 2003 2254 969 1454 1938 2423 2907 3392 3876 4361 1317 1979 2637 3296 3955 4613 5275 5933 1709 2562 3419 4272 5125 5981 6837 7691 UIN 145016 145017 145018 145019 145020 145021 145022 145023 145040 145041 145042 145043 145044 145045 145046 145047 145064 145065 145066 145067 145068 145069 145070 145071 Heat output Watts Btu/hr 348 522 696 870 1044 1218 1392 1566 478 717 956 1195 1434 1673 1912 2151 615 922 1230 1537 1844 2152 2459 2767 1187 1781 2375 2968 3562 4156 4750 5343 1631 2446 3262 4077 4893 5708 6524 7341 2098 3146 4197 5244 6295 7343 8393 9441 ∆t50 is the UK’s industry standard for heating outputs, which has an operating temperature of 75/65/20°C if you have a low temperature heat source you may wish to consider ∆t40 or ∆t30 output (see your installer or system designer).
