BOILERS, PUMPS & VALVES SPACE SAVING HEATING SOLUTION


With its previous floor standing system taking up much of the plant room floor at Mulalley and Co’s Teresa Gavin House, Hamworthy Heating proposed a system using two Wessex ModuMax mk3 floor-standing, vertically stacked modules


with a total power outlet of 464kW, a new plate heat exchanger and a Chesil pressurisation unit. In line with updates to the existing building regulations Part L, a new boiler flue was also fitted as part of the new installation. The new upgrade at Teresa Gavin House replaces seven NGR


floor-standing cast iron sectional boilers from Hamworthy Heating that have been in operation for nearly 30 years. Available in five modules with outputs (@80/60˚C) of 97, 116,


147, 196 and 254kW), the Wessex ModuMax modules can be stacked two or three high in up to 15 combinations up to 762kW output. Providing the benefits of high turndown ratios and load matching for improved efficiencies, the system delivers the right amount of heat at the right time, with little or no wastage. Michael Danes, Mulalley and Co. said: “Hamworthy products offer a robust and reliable solution, backed by an exemplary service and market leading warranty. Any minor issues or questions we had were handled quickly and easily by the Hamworthy team. We’re looking forward to seeing the expected benefits of the new Wessex ModuMax mk3 system at Teresa Gavin House.”

NEW LOW VOLTAGE INDUSTRIAL ELECTRIC BOILER OFFERS MAXIMUM EFFICIENCY


Babcock Wanson has launched the LV-Pack low-voltage industrial electric boiler, which provides steam outputs from 600 kg/h to 8400 kg/h and a design pressure of up to 18 barg. Specifically designed to provide maximum


efficiency – over 99%, as all incoming electrical energy is converted into thermal


energy – with zero CO2 and NOx emissions, the LV-Pack has been introduced to help meet European requirements for energy optimisation and reduction of greenhouse gas emissions. Being electric with no emissions


makes for easy installation and commissioning, and periodic monitoring of atmospheric emissions is not required. The boiler is delivered to site and, once connected to the electricity, the feed water and the steam network, is ready to operate, the company explains. The control and instrumentation allow for Babcock Wanson’s boiler operating modes


to be used, which provide integrated monitoring and regulation of all the equipment in the boiler house, as well as providing real-time monitoring and data logging. These modes include BW3DAYS with tests every three days, and BW7DAYS which tests every seven days. LV-Pack boilers are also fitted with the Navinergy monitoring interface, which enables both on-site and remote monitoring of operating parameters. Of further benefit, precise pressure control with multiple power stages enables it to react quickly to load changes. This makes it possible to make quick starts to absorb available grid power when needed.

HIGH EFFICIENCY AIR-TO-WATER HEAT PUMPS UNVEILED


LG Electronics (LG) has unveiled its new Therma V R290 Monobloc 7- and 9-kilowatt (kW) air-to-water heat pumps (AWHP). Following the successful launch of the large capacity models (12, 14, 16kW) last year, the new models come with an advanced compressor that unlocks greater efficiency and a more sophisticated design that blends seamlessly into the surroundings. With the mandatory implementation of Nearly-Zero Energy Buildings (NZEB)


standards across Europe, AWHPs are gaining popularity for their ability to reduce carbon emissions and handle energy supply uncertainties. For new constructions, medium- and small-capacity models are more suitable, making LG’s new 7- and 9kW models ideal for the European market. LG has adopted the R290 refrigerant for its Therma V R290 Monobloc. This natural


refrigerant has a Global Warming Potential (GWP) of 3, far lower than the refrigerants commonly used in heating solutions. With an energy rating of A+++, this solution reduces carbon emissions by up to 79% compared to conventional boilers by sourcing its energy from heat in the air, the company states. Customers upgrading to the Therma V can expect to increase their household energy efficiency significantly. The latest Therma V AWHP leverages LG’s


advanced compressor to unlock new levels of energy efficiency and performance in colder climates. The lower positioning of the compression process helps ensure a more stable operation and smaller energy bills, while the system enables a water output of up to 75˚C, even when it is -15˚C outside. Courtesy of the all-new compressor, both


AWHP models operate at a quiet 49 dB(A) at 7kW and 50 dB(A) at 9kW.

MEETS THE RIGOURS OF MODERN POWER GENERATION


The robust DSCV-SA (Direct Steam Conditioning Valve – Steam Atomization) from the Copes-Vulcan brand of Celeros Flow Technology is designed to meet the rigours of modern power generation using superheated steam. Already relied on in power generation, refineries and paper mills, the DSCV-SA is also finding new applications in renewables, including waste-to-energy plants. Valves for superheated steam control need to deliver


operational reliability and withstand extreme conditions. The DSCV-SA addresses the issues encountered by older, base load designed bypass valves when employed on modern high frequency, rapid ramp rate plants. It is designed to use high-pressure balance which eliminates risk of wear, damage or breakage relating to piston rings and balancing systems. It also avoids stem load fluctuations due to worn seals and surfaces, which can cause low-pressure valves to oscillate violently or not open on command. The DSCV-SA features steam atomization technology. With this,


the cooling water is pre-heated, significantly accelerating the evaporation and desuperheating process and producing extremely small water droplet sizes with a vastly increased surface area to promote rapid heat transfer. Because this method of water introduction does not rely on surrounding steam velocity or turbulence for effective mixing, it gives very high turndowns - generally in excess of 100:1. This also features a ‘Quick-Change’ style trim meaning in-situ maintenance, if required, is quick and simple.
