Embracing SANHA’s Lead-Free Fittings: Safeguarding Water Quality and Health
Chilled Water Reimagined – Adveco CWT A
dveco completes the reimagining of its chilled water vessel offering with CWT. Following the introduction of the premium Chilled
Water System (CWS) tanks, it now re-releases its Chilled Water Tank (CWT) range with a complete redesign intended to serve a wider range of central heating and chiller applications requiring expanded total system volume and increased thermal inertia. This range of carbon steel primary system vessels
- available in 300-5,000 litre capacities - is a key element for maintaining comfortable temperatures in commercial buildings for occupant The most common applications are based around chiller plants, fan coil units (FCUs) or air source heat pumps (ASHPs). When used in combination with traditional chillers, the tanks create a buffer, allowing the chiller to operate in longer cycles even during peak demand periods. This reduces energy costs and extends chiller lifespan. In buildings with FCUs, the CWT provides the cool water circulated through the FCUs’ heat exchangers, cooling the air in individual rooms or zones. Chilled water tanks can also be integrated with reversible ASHPs. During cooling periods CWT can be used to store chilled water; during heating seasons they could

be used as thermal buffers for hot water generated by the heat pump, although designated tanks for heating and cooling are recommended for commercial-scale applications. CWT can also be combined with solar thermal systems where heat captured from solar thermal collectors can be deployed in an absorption chiller where a refrigerant is boiled, creating expanding and cooling vapor to produce chilled water held in the CWT which is supplied with a 25mm insulation vapor barrier. This combination of solar thermal and inertia vessel can save significant amounts of energy, reducing reliance on the grid and lowering electricity bills, not only during the summer months but also contributing pre-cooling in shoulder seasons. The CWT range is suitable for use with working pressures up to 3 bar standard, 6 bar also available
and temperatures from -10 to 95°C. The entire range is supported by a selection of ancillaries including control and overheat thermostats, automatic air vents, and gauges. Commercial buildings with cooling needs will benefit most from the efficiency gains offered by
CWT vessels and, with multiple connection options compatibility is maximised enabling the tanks to be integrated with various systems. Factoring in the capability to facilitate the use of renewable energy sources for cooling, plus the energy savings and reduced operational costs over time, capital investment in this range of standard vessels proves extremely cost-effective. Plus their adoption also helps organisations to contribute towards sustainability objectives and achieve strategic goals as part of a building-wide net zero initiative. Seek professional guidance from Adveco to evaluate your chilled water demands. We can help determine if CWTs are the key to unlocking a more efficient, sustainable, and comfortable cooling solution for your commercial space.

ESP offers a total fire protection package
SP’s extensive fire protection product range offers a solution to suit any size of project. The range is broadly divided into two categories. The first category
- MAGfire four-wire and the MAGDUO two-wire fire alarm systems - is aimed at small to medium contractors, offering them a highly flexible and adaptable system that will save them time and money on the installation process. Whilst the second category - the MAGfire addressable systems - is suitable for large commercial premises and more complex networked systems. Fire alarm systems are broadly divided into two main groupings - “conventional” fire alarm systems and analogue addressable “intelligent” systems - with each type best suited to different kinds of premises. Conventional, or four-wire, fire alarm systems have been traditionally used in smaller properties such
as shops and restaurants. They work by dividing the building into a number of detection zones, with the detectors and call points within each zone hardwired on dedicated two-core cable to the control panel. There may be multiple detectors on a single zone. Addressable or “intelligent” fire alarm systems are designed for large commercial premises and more complex networked systems. They offer increased flexibility, intelligence, speed of identification, and scope of control. Different types of initiating devices are wired in one or more single loops around the premises, requiring less cabling than conventional systems, with each detector or call point having its own unique address. Two-wire fire alarm systems are based on standard conventional system technology which allows all devices to be wired on the same set of two-core zone cables back to the control panel - enabling it to use a single circuit per zone both for detection and to power the sounders. This advanced technology can reduce both installation and material cost.
Design and commissioning services ESP offers a dedicated fire design service for contractors. Available to any size of business, from local electricians to national contracting companies, the aim is to provide expertise in choosing the right products and solutions to create a scheme that meets all the requirements of the project in question, as well as the relevant standards.
