Toshiba
Toshiba Carrier UK (TCUK) has rolled out the latest generation of its high- performance ESTIA air-to- water heat pumps operating on lower global warming potential (GWP) refrigerant R32.
ESTIA, operating with R32 refrigerant,
provides highly efficient space heating and domestic hot water (DHW) for year-round comfort in homes and small businesses. Designed to meet increasing demand for a lower-carbon alternative to traditional heating technologies, ESTIA units harness ambient thermal energy from outdoor air, reducing energy bills compared to some other types of units. The heat pumps support Carrier’s 2030 Environmental, Social & Governance (ESG) Goals of reducing customer’s carbon footprint by more than 1 gigaton. Four models are available in the ESTIA range, spanning capacities from 4 to 11kW, with larger capacities available soon, all with reversible operation to provide cooling as well as heating, if required.
At the heart of ESTIA is Toshiba’s award-winning twin rotary
compressor, which contributes to the system’s outstanding energy efficiency rating of A+++. The pioneering compressor enables the heat pump to continue supplying hot water to the heating network even during exceptionally cold weather, delivering water at 62degC when outdoor temperatures fall to -25degC. At the other end of the temperature scale, ESTIA can continue producing DHW at exceptionally high outdoor temperatures (43deg C) to deliver maximum running cost savings. For gas boiler replacement projects, Toshiba offers a space- saving wall-mounted hydro-module with a choice of 150l, 200l or 300l capacity external cylinders. For use in new-build projects, an all-in-one floor-standing hydro-module with an integrated 210 litre tank provides a super-compact solution for both heating and DHW storage. To ensure continuity of operation at extreme low ambient air
temperature during winter, ESTIA is equipped with an integrated back-up electrical heater (3, 6 or 9kW) to maintain heating and hot water production at all times. For contractors, ESTIA is quick and easy to install and maintain, with hydro-modules providing front access to all key components.

Aqua
Temperature control specialist, Aqua, has launched a new range of completely packaged chillers. The Aqua Pro units have been specifically designed for process applications and display an impressive array of standard features. The chillers cover cooling capacities
from 1kW to MW+, working with process fluid temperatures from -25°C to +20°C. As well as a process specific design, incorporating an innovative coaxial evaporator, the Aqua Pro demonstrates a real commitment to reducing energy costs and carbon impact. The Aqua Pro utilises a 0.7mm thick copper coaxial evaporator, with 8mm water pathways. The larger than normal pathways eliminate any risk of blockage and subsequent evaporator damage. Water contamination by debris is all too common within the process industry, so this design feature is a clear benefit. The condenser within the Aqua Pro is 0.4mm thick copper construction, double the industry standard of 0.2mm. “The Aqua Pro range is here to make a difference to the industry,”
explained Aqua sales director, Owen Hymers. “We wanted to design a chiller that can stand up to the demands and challenges that the process market faces daily. Yet we also wanted to tackle, head on, the issues around energy consumption and the environment that are impacting us all. “Low GWP R454B refrigerant comes as standard, as does completely integrated free cooling. R454B has a GWP rating over 75% lower than R410A, one of the most deployed refrigerants within our industry. R454B achieves a balance between optimal efficiency and performance levels whilst addressing pressing environmental concerns. “The Aqua Pro achieves free cooling at higher ambient
temperatures than any of its contemporaries. We have helped customers dramatically cut their energy costs by using free cooling – in some cases by 80%. It’s a real game changer, not just for customers but also the environment.” Aqua holds stock of the Aqua Pro range at its Hampshire-based head office and warehouse facility, enabling them to offer next day, UK wide delivery.
