Newly-developed radiators keep surface temperatures low
System perfect when safety is paramount
Dunham-Bush has developed and launched a new range of low surface temperature (LST) radiators, a further development of the company’s Warmsafe range.
The System LST range has been re-engineered to incorporate finned tube heat exchangers, which result in more opportunity to achieve the all-important touch temperature requirements, not only of the case, but also of the air outlet grille. Alongside the finned element-based product, a full range of System LST models is offered which incorporate panel type radiators. System LST is designed to provide comfort heating in applications where safety is paramount, making them especially suitable for hospitals, care homes, day centres, playrooms, surgeries and nurseries.
A simple-to-use selection program enables the building designer to select a radiator that will provide the required heating capacity at design operating conditions and required case and grille temperature.
The System LST range is available with finned tube elements or panel radiators in a range of enclosures which include wet floor and ‘tall’ units for specific applications.
The units can be supplied with a choice of industry standard manual or automatic controls which can be handed to suit the installation, and can be reversed if required even after the units are at site. The enclosure is of all-metal construction with an aluminium grille for strength and stability and rounded corners and white powder paint finish for durability. Other colours are available.
The System LST has been designed taking into account the requirements of the construction industry. The wall-mounted back plate and emitter can be supplied in advance to enable to pipe work to be connected and tested before the enclosure is fitted. The back plate acts as a template for fitting the enclosure and provides location points without any further measurement. While fully secure once fitted, the front plate and top grille are removable for cleaning after the security locks are released, but without the need for any other tools. This feature enables cleaning and adjustment of internal controls where specified. The System LST range has been tested in accordance with BS EN 442 and part of the testing was to establish which units and at what water temperature, satisfy the requirements of the NHS guideline commonly used as a basis when specifying low surface temperature radiators.
Three styles of enclosure are offered: wall mounted, floor mounted and floor mounted with plinth to accommodate pipework. Each type of enclosure can accept pipework entering from below, behind or from either side, with sufficient clearance in the case to fit the necessary valves and controls.
Dunham-Bush managing director, Mike Holding, said: “Where children and vulnerable adults are concerned, heating and radiator safety is critical. We have followed the NHS Estates Health guidance for designers on safe surface temperatures, which states that ‘the surface temperature of space heating devices such as storage heaters and radiators …should not exceed 43°C.’ System’. LST products can be selected across a range of outputs and operating conditions to comply with this guideline.”
The range includes intermediate and tall vertical cases, and all units have been designed for simple site installation. For almost all of those available this can be completed by one person.
System LST is tested and rated to BS EN 442 and Dunham-Bush operates a quality system, attested by its registration as a firm of assessed capability to BS EN 9001: 2008.
