Improved performance from Strebel Air Source Heat Pumps


A


ir source heat pumps are now a popular heating and hot water solution for a wide range of


decarbonisation projects in commercial properties, as the building sector seeks to meet the UK’s net zero commitments. Established boiler manufacturer,


Strebel Ltd, added heat pumps to their product portfolio in 2018. Several product development and enhancements have followed the initial launch and further improved the previous high levels of performance. The new S­ASX­21 air to water heat pump is available with heating capacities ranging from 60kW to 100kW. The units are suitable for multiple installations of up to 16 units operating in cascade. Seasonal co­efficiency of performance (SCOP) is a key performance measure for all heat pumps and the S­ASX­21 offers a favourable SCOP up to 4.41 at 35⁰C and 3.52 at 55⁰C. This range benefits from an enhanced vapour injection (EVI) design that, along with a well­matched


compressor and refrigerant combination, helps to achieve flow temperatures of up to 65⁰C. EVI also ensures that heat output degradation is minimised when ambient temperatures drop to lower than 0⁰C. Unlike many other rival heat pumps the S­ASX.21 unit can deliver 65⁰C even when ambient falls to minus 22⁰C. Other standard features include compressor soft start, ModBus connectivity and an integrated fully


modulating pump allowing close matching of heat demand to delivery. S­ASX­21 units are of monobloc design, suitable for outdoor installation and integral dampers provide low acoustic performance. “We saw growth in demand for our heat pumps in 2021 and the early signs are that this will increase further in 2022 and beyond. The recent performance upgrades we have made provide design engineers, contractors and end users with a high­performing heat pump solution” says Strebel UK National Sales Manager, Adrian Walker. “The efficiency of a heat pump is of particular importance in keeping running costs at reasonable


levels; that’s especially important for businesses and organisations who have traditionally had heating and hot water systems powered by gas­fired products” he added. Strebel UK was established in 1970 since when its products have provided heating and hot water solutions for commercial applications such as schools, university buildings, hospitals, care homes, offices, and multi­residential buildings.

New connected HIU uses IoT to improve efficiency and installation


reducing costs and carbon emissions for clients and end users alike. The new generation electronic HIU is the first to use 5G NB­IoT and the


T


Amazon IoT platform to provide full remote connectivity with the energy centre, wider heat network management and optimisation systems. This delivers highly reliable, low­cost, two­way communications over a management platform that can be accessed from any web device. Richard Harrison, CEO of Switch2 Energy said: “On existing heat networks,


ICON is helping to improve heat network efficiency by up to 35% – resulting in large cost savings and reducing CO2 emissions by as much as 40%." The electronic HIU's remote management portal enables installers and operators to monitor


performance and update settings for the entire heat network. This simplifies and accelerates the installation, commissioning, and verification processes – providing transparency, cutting costs and easing the road to practical completion. Remote connectivity and real­time monitoring also enables operators to optimise lifetime heat


network performance ­ driving low cost operation and proactive maintenance, improved efficiency and reliability, carbon reduction and better customer service. Other benefits of the ICON HIU remote management portal include: • Operators can quickly and efficiently set up, commission and verify performance of HIUs and tertiary systems. • Complete system transparency enables installers and operators to identify common quality issues, such as crossed flow and returns.


• Settings can be remotely monitored and changed to ensure optimum HIU performance, according to varying network conditions. This is particularly useful during initial heat network tuning and validation and supports CIBSE CP1 verification compliance. • Identify HIU errors remotely, often before interruption to service – enabling targeted planned maintenance and reduced emergency call outs. Designed for modern next generation heat networks to CIBSE Code of Practice guidelines, and with full WRAS and BESA approval, the UK manufactured ICON HIU offers multiple connectivity options, including 5G NB­IoT, GPRS, Ethernet, ModBus and MBus. There is no vendor lock­in because the HIU management portal is open to authorised third parties .


ICON also supports third party billing and payment systems, with no additional hardware requirements, such as cut off valves. In addition, ICON incorporates an automatic meter reading system, avoiding the usual capital cost of purchasing separate equipment. Richard Harrison continued: “We are proud to lead on smart technology innovation and look forward


to helping installers and operators to deliver greener, high efficiency, lower cost new generation district and community heating schemes."

Luceco ‘s Anti­Ligature Luminaire Range


L


uceco offers a range of Anti­Ligature luminaires providing lighting solutions for use in Care Homes, Custodial Units, Prisons and Mental Health Facilities. Anti­ligature luminaires are designed to prevent self­injury, as there are no fixing points or attachment areas that could enable a luminaire to be used for self­harming. Popular luminaires often considered for these settings have been included in this range, notably Atlas, Climate, Platinum and LuxPanel. The Atlas Anti­Ligature Bulkhead features spun steel construction suitable for where access to the


fitting is expressly limited to authorised persons, with counter sunk screws securing the luminaire. Climate is another robust anti ligature linear luminaire suitable for where vandalism may be an issue with an IK10 rated steel body with UV stabilised fire retardant polycarbonate diffuser with tamper resistant screws. Recessed options include the Platinum Downlighter and LuxPanel lay in luminaires. The Anti­Ligature LuxPanel features a steel frame with a UV stabilised and fire retardant


polycarbonate diffuser with flush anti tamper screws. Anti­Ligature LuxPanel can be installed in SAS style metal ceiling grids and can be offered in dimmable, emergency, and self­test options. The Anti­ Ligature Platinum Downlight’s engineered bezel design provides a sturdy construction and is supplied with anti­tamper security bolts with long reach swing tabs for ease of initial installation.

Simplify data security in your facilities with RC­RemoteAccess®


treamline your IT management and improve data communications security with RC­ RemoteAccess, a flexible BACnet Secure Network solution for building automation systems that lets you simply create and manage encrypted BACnet networks in a facility without additional routers or controllers. With RC­RemoteAccess you can:


S


Secure your communications • RC­RemoteAccess provides a Transport Layer Security data link for communication over a BACnet Virtual Private Network with 256­bit data encryption.


Simplify BACnet internetwork routing • RC­RemoteAccess uses BACnet/IP routing, which allows you to easily connect multiple remote devices across a wide area network and eliminates the need for unsecured port forwarding through routers, static IP address, or BACnet Broadcast Management Devices.


Integrate with BACnet File Services • Because RC­RemoteAccess natively supports BACnet, you can run any operation that uses BACnet File Services over the BACnet Secure Network connection.


Improve your network resilience • With RC­RemoteAccess, you can set up a failover server; if the primary server goes offline, connected BACnet Secure Network clients are automatically moved to the failover server without network interruption.


RC­RemoteAccess makes data security easy and affordable. Find out more on the website. reliablecontrols.com/bsee
