Intensse air curtains at new St Barnabas
JS Air Curtains has supplied four designer air curtains to the recently opened St Barnabas House hospice in Worthing. Two 1.5m and two 2m Intensse air curtains are preventing cold air from entering the reception of the newly built £13.5 million healthcare development. The Intensse air curtain has an attractive oval design, strip lighting, a built- in fragrance option and germicidal UVC lamp to eliminate airborne viruses and micro-organisms, making it ideal for healthcare environments. A casing encapsulates the mounting arm to give a seamless finish to the air curtain’s design. The air curtains were specified by sustainable design consultants, John Packer Associates in Uckfield, and installed by SMS Southern Ltd of Brighton. St Barnabas House offers specialist palliative care to patients, their families and carers living in Worthing and the surrounding area. It opened in March 2011 and was almost entirely funded by voluntary grants, donations and fundraising activities. The Intensse air curtain is available in 1m, 1.5m and 2m lengths with fan powers
up to 3,800m³/hr and heat outputs from 9.5 to 36kW, making the model ideal for entrances up to 2.8m high.
The air curtain at St Barnabas is dark grey with black colour trims. However, it is also available in two other standard metallic options; silver or champagne, and also any RAL colour on request. Strip colour trims around each end can be specified to tie-in with an interior and white, red, blue or green fluorescent lighting tubes can be fitted within the air intake section to provide attractive additional lighting to an entrance.
Fast heat wire elements and an energy saving power regulation system reduce energy consumption by up to 20% compared to standard electrically heated air curtains. The wire elements within the unit heat up to temperature in just 5-10 seconds rather than the 120 seconds it takes a stainless steel heating rod to reach temperature. Once the internal temperature nears its set point the air curtain will pulse the power to the
elements, reducing the overall energy consumption and maintaining a more consistent internal temperature. Control is via a digital wired remote control and up to six units can be chained under one control mechanism. Alternatively the Intensse can be linked to a building management system. JS Air Curtains supplies an extensive range of air curtains, as well as bespoke solutions, for all commercial and industrial applications. JS’ in-house project management division can also provide a smooth, hassle-free installation service that walks the customer through from design specification to post-installed product training.

Packaged intelligent pump solutions
Armstrong has launched a series of pre- designed packaged pump solutions that offer specifiers lowest first installed cost, reduced footprint and the opportunity for outstanding energy efficiency performance. Pumps, pipework, controls and motive power are fully-integrated and the packages are manufactured off-site, for fast, efficient installation.
The traditional approach to purchasing a pumping system is to procure pumps, pipework and controls separately, and build the system on site. Armstrong is extremely experienced in offering a more effective option. The new 8000 Series of Fully Integrated Pumping Modules however takes this a step further. The new 8000 Series are complete fluid management systems, pre-designed and pre-assembled by Armstrong, that can be configured to suit the widest range of applications, with a choice of four levels of control. Costs involved in designing the system are removed, and as the pump solutions are designed by Armstrong they offer the best possible integration of pumps with controls technology for exceptional performance.
In addition, as the pump package is fully assembled and tested before it leaves Armstrong’s factory, many potential project risks are eliminated. Poor system integration during installation is avoided, and the pump solution can be

manufactured concurrently with other parts of the construction or refurbishment project to reduce the schedule significantly, at the same time as avoiding delays or bottle-necks that might occur on-site. These factors combine to offer specifiers a high- performance product solution, at the lowest first installed cost, with reduced risk and shorter installation times.
The four options encompass the widest range of requirements – from pump-only to fully controlled pumping systems. • 8001 Series FMS (Fluid Management System) – the most basic option – is a traditional-style fixed speed packaged pump set without controls or variable speed drives.
• 8002 Series IVS (Intelligent Variable Speed) is a variable speed packaged pump set. It incorporates Armstrong’s extremely popular IVS pumps with motor mounted inverters that are capable of being controlled to meet demand.
• 8003 Series IVS (Intelligent Variable Speed Sensorless) also incorporates Armstrong IVS variable speed pumps with motor mounted inverters. It utilises sensorless control, reducing
the requirement for sensors in the systems, and automatically matches the pump speed to the building load without BMS control. This option is particularly suited to duty/standby applications (up to 90kW) and includes a set mounted control panel that shares the load of the duty pump and relays alarms to the BMS. It is suitable for single zone control.
• 8004 Series IPS (Integrated Pumping System) is capable of controlling up to 18 zones and includes Armstrong’s set mounted IPS (Integrated Pumping System) which is fully wired and pre-commissioned to the pumps within the set. The system is capable of operating outside of BMS control and can communicate to the BMS via Modbus as standard. Lonworks, BACnet and other protocols are also available on request.
The 8000 range is based on the pump manufacturer determining how the pumps are controlled. This is accepted best practice for energy efficiency, equipment life, and simplicity of installation and commissioning, further reducing risk and carbon emissions.
