LG
LG has launched the latest version of its sector leading Therma V Monobloc air to water heat pump – the Therma V R32 Monobloc ‘S’ – into a UK marketplace that is highly responsive to new heat pump technology. The ‘S’ stands for ‘Silence’ and ‘Supreme’ to highlight its reduced noise level and best performance criteria. The announcement recently from Government that it will provide a £5,000 grant from April 2022 to individuals choosing to install a heat pump over existing fossil fuel driven heating systems is the next crucial step towards major uptake of proven heat pump technology in preference to reliance on gas, oil and solid fuel options for domestic heating and hot water provision in the UK. The Future Homes Standard requires serious action and quickly if targets are to be met. Renewables and higher standards of building quality in, for example, recognition of better standards of insulation in UK homes are key to meeting the aims of the FHS. Heat pumps have a major part to play. The original LG Therma V Monobloc has already seen enormous success in the UK marketplace as heat pump sales in 2021 trebled over sales in the previous year. But this new ‘S’ version is set to make unparalleled sales figures in 2022 as more and more housebuilders and developers, local authorities and social housing providers move to use renewable options in their new build homes and begin the process of replacing older and inefficient gas boilers with an option that future proofs their existing homes in the years ahead. As with the original Monobloc, this new model combines the indoor and outdoor features in one module. It’s also connected by only water piping, eliminating the need for refrigerant piping, making this heat pump an installer’s dream when it comes to ease of installation. Hydronic components like the improved plate heat exchanger, the expansion tank, water pump, flow sensor, pressure sensor, air vent valve and safety valve are all built in - inside the outdoor unit – pre- installed and ready to run. And the R32 Monobloc ‘S’ provides excellent heating performance especially at low ambient temperatures whilst lowering its carbon emissions even more with the use of R32. The design and technology in this new unit sees built in water flow and pressure sensors to monitor the water circuit in real time, advanced water pump control, enhanced second circuit logic, energy monitoring of estimated power consumption via the remote controller, MODBUS connectivity without Gateway if required and advanced control for the domestic hot water recirculation pump.

Envirotech
The EnSolv CC-A formulation for precision metal cleaning responds to the need for high performance vapour degreasing solvents for critical cleaning in general engineering, aerospace, medical optical and electrical industries. It removes cutting oils, lubricants, lapping compounds grinding pastes and water based cutting oils or fluids. This complex synergistic blend utilises environmentally compliant solvents combined with selected surfactants to remove oils and lubricants to the highest standards for critical cleaning applications and releases and suspends inorganic solids and soils such as fingerprints, polishing compounds and grinding paste from finely finished and highly polished surfaces such as stainless steel and plated parts, optical lenses and components for medical appliances. EnSolv CC-A is a proprietary blend of inhibitors and stabilisers for the solvents to prevent water staining and corrosion of yellow metals such as copper, brass and bronze which can be a problem with some other solvents. It is non-flammable, stable and specifically formulated for use in any vapour degreasing equipment with the added advantage of lower solvent usage, greater stability and reduced costs. The formulation is compliant with all current environmental and user safety legislation. X

Honeywell
Honeywell has announced that its Solstice technology is supporting a new range of ultra-low GWP scroll compressors designed and manufactured by Danfoss for heating and cooling applications. The new compressors deliver improved energy efficiency over models based on R-410A, while offering the same cooling capacity and similar footprint. Danfoss will use Honeywell’s Solstice ze (R-1234ze) and Solstice N15
(R-515B) refrigerants in its new DSG scroll compressor range for chiller and heat pumps used in commercial buildings, industrial processes, data centres and district heating/cooling applications. The compressor range will be available in Q2 2022, and will allow chiller and heat pump manufacturers to stay compliant with regulations requiring the phasedown of higher-GWP hydrofluorocarbons (HFCs). With a GWP of less than 1, Solstice ze is 99.9% lower than R-410A and
other HFCs. Solstice N15 (R-515B), a non-flammable, low-GWP solution, has a GWP lower than 300 and provides higher energy efficiency in the DSG compressor range than the R-410A models. Both refrigerants are based on Honeywell’s hydrofluoroolefin (HFO) technology. The DSG compressors are specifically designed for medium pressure chillers to cool large buildings, infrastructure projects, district cooling/heating, and other applications. With this new compressor technology, the use of R-1234ze and R-515B will have the possibility to expand into OEM’s scroll chiller platforms X
