You can count on commissioning

It is now more readily understood that correct sizing and careful pump selection can make a significant difference to the overall energy and CO2 output, as well as the need to futureproof these designs.

Back to basics

Hydronic system balancing is one of the more complicated tasks faced by building services engineers and historically heating and chilled water systems were balanced by specialist engineers only.

Viega, Scott James, press connection
Press fit solutions are ideal where hundreds or even thousands of connections are needed on large projects.

Considered connections

Speed is of the essence when it comes to pipe fitting in today’s large-scale projects. Scott James offers his advice on making the right choice.

A small plant room is no bar to modern technology

Feeling the SQUEEZE

M&E contractors and building services managers looking to maximise space within plant rooms have a checklist of utilities to consider - heating systems are just one of many to juggle. And boilers are just one piece of the plant room jigsaw that needs to slot into place. However, with strict guidance and legislation around the area required for ventilation, access for handling units and clearance in line with manufacturer’s guidelines for maintenance for example, it is a headache for many.

Commissioning Specialists’ Association opens entries for its awards scheme

The annual awards of the Commissioning Specialists’ Association is open for entries. This is the third year of the awards, which acknowledge the achievements and efforts of companies and engineers. Products, systems and services that are essential for the smooth and efficient operation of any built environment will also be recognised.

Grundfos Pumps, commissioning

Perfectly balanced with Grundfos

Getting the right balance on domestic heating system is a simple task with the help of the Grundfos Alpha3 system. The company says that 86% of domestic heating systems are not balanced and that balancing a system can reduce heating costs by 5 to 17%.

Optimum operation — Matt Peasnall.

Controls and services in sync.

Making alterations to a building and its services without making corresponding changes to the controls will quickly lead to poor performance and increased energy consumption. controls are not fit-and-forget technology — as Matt Peasnall of Trend Control Systems, explains.

Belimo EPIVs help keep leisure centre open during renovation

As part of major renovation of the heating-distribution and complex ventilation system of the Happyland leisure centre in Klosterneuburg, Austria, 45 Belimo EPIVs (electronic pressure-independent control valves, the orange units in the picture) were installed on eight distribution circuits during operation to avoid loss of revenue.

Flow-limiting valves help maintain low system temperatures

The PT40 range of radiator control valves from SAV Systems helps to reduce energy waste in heat networks by ensuring that radiator systems are well balanced. These TRV sets are presettable to a flow-rate limit at each radiator, in line with the CIBSE ‘Heat networks code of practice’, eliminating the need for traditional balancing.

Siemens PICVs are selected on flow

The only information needed to the size of Siemens Acvatix PICV (pressure-independent control valve) is the required flow through it, saving time for the specifier. These valves automatically shield against pressure fluctuations in a network to maintain a constant flow. The are available in sizes from 15 to 150 mm (a 50 mm size is pictured).
