The S400 and S600 can service higher volumes of water than ever before and feature menu-guided commissioning as well as remote access and operation via the cloud.
The changes have been made in response to the market, which is looking for greater connectivity alongside reduced energy consumption delivered with the aid of deaeration products that can operate effectively in today’s increasingly large commercial buildings.
The vacuum degassers work by decreasing the pressure in the vacuum vessel that sits within the unit. This liberates dissolved gases from the system liquid in the vessel and the accumulated gases can then be expelled.
Any air left behind leads to corrosion and a destructive sludge developing, also creating noise from components such as pumps which cease to work efficiently.
The powerful vacuum degassers are needed because ‘ordinary’ in line deaerators will not work anywhere near as effectively in high-rise offices and other tall buildings.
By continuously degassing quantities of the system liquid, the SpiroVent Superior keeps the negative effects of dissolved and liberated gas to a minimum.
A smartswitch continuously monitors the volume of removed air, and will switch off when the minimum dissolved gas level is reached.
The S400 can degas 500 litres or water per hour, while the S600 can manage 1,000 litres an hour.
The degassers also ensure the system pressure never drops too low, with positive pressure maintained throughout.
They also include a Category 5 break tank, best suiting the requirements of the UK market. The break tank ensures that a ‘more than adequate’ backflow prevention is achieved, while avoiding costs associated with the alternative solution of a Reduced Pressure Zone (RPZ) valve.
The SpiroVent Superior S400 and S600 are easy to install and engineers can access quick installation guides by scanning a QR code on their mobile phones.
Once commissioning is complete, control and monitoring can be done using a touch screen on the unit, through a building management system (BMS) or via the internet on a PC, tablet or smartphone.
Functions such as on/off, error and alarm reset, and degassing, refill and boiler interlock on/off can be controlled remotely, while parameters can be set for aspects such as system pressure, refill pressure and boiler interlock.
The new SpiroVent Superiors also include a comprehensive unit status and event history, providing real-time data and enabling performance to be tracked in detail over time.
Mark Boccetti, technical advisor for Spirotech UK, said: “The new SpiroVent Superiors have been developed based on Spirotech’s 30 years’ experience in degassing technology. They are the most effective degassers on the market and, we believe, are the only units that offer the three functions of degassing, pressurisation and a Category 5 break tank in one single unit.
“The flexible, high level connectivity they offer is an exciting addition that meets the market’s requirement for more information gathering. This will, among other things, enable predictive maintenance and servicing, leading to increased reliability and performance, and ultimately cost savings.”
