Worcester Bosch

Greenstar 4000

Replacing the manufacturer’s “highly popular” Greenstar i series, the Worcester Bosch Greenstar 4000 has been designed to build on the “tried, tested and much-loved features” of its predecessor while receiving upgrades to its appearance and performance.

Key improvements are said to include increased ease — and speed — of installation, commissioning and servicing, alongside improvements in efficiency and control for the user. Encompassing features from its range-topping 8000 Style, the new unit is said to deliver real advances in siting flexibility not least in matching the fixing points, pipe centres and flue to valve distance of predecessor models to facilitate simple retrofit installations.

Sanifos underground pumps

The Sanifos range of underground pumps has been refreshed with two model upgrades and further extended with a number of new models. The Sanifos 280, for example, replaces the original 250 and offers an additional 30 litres capacity whilst the new Sanifos 610 provides a “huge” 110 litres additional capacity over its 500 litre predecessor.

For public buildings or for multiple smaller buildings, Saniflo has introduced four large capacity models starting with the Sanifos 1300 which can pump waste up 17m. Three further models — the 1600, 2100 and 3100 — are said to enable customised lifting station solutions according to the project in hand.

Aquaboost iBolt

Available as a stand-alone single pump or single and twin booster sets, the Aquaboost iBolt range of variable speed booster pumps and pump sets feature horizontal multistage pumps controlled by air-cooled variable speed frequency inverters mounted directly on the pump motor, designed to deliver a constant water pressure supply where flow demand varies. Mounted directly on the pump motor, these high performing, yet intuitive to commission pumps deliver flow rates from 5 m³/hour to 15 m³/hour and head pressures up to 9.0 bar depending on the chosen variant within the range.

With an added buffer of pressurised cold water to supplement pressure and flow, Aquaboost iBolt Booster Sets are supplied with a WRAS approved 8 or 24 litre pressure vessel, combined with either a single or twin pump set mounted on a powder coated base plate for ease of installation.

Twin booster sets offer up to 15 m³/hour per pump with heads up to 7.1 bar.

SpiroVent Superior S250

For smaller commercial closed heating and cooling systems, Spirotech has added to its range of vacuum degassers, introducing the SpiroVent Superior S250. Appropriate for locations such as schools, restaurants and larger domestic properties, it is designed to operate almost silently.

The S250 has been created in response to increased demand for low-temperature systems, such as in underfloor heating where it is difficult to detect where air can be released from. The S250 processes up to 74 litres of liquid each hour and operates at 41 decibels.
