A good hydraulic balance is highly important for HVAC and process systems with separated circuits or several groups and pumps. The effective removal of air and dirt also contributes towards the achievement of optimum system performance. Hydraulic balancing and air and dirt separation are combined in the SpiroCross. The SpiroCross can be used for both new build, refurb and projects for refurbish heating, cooling and process systems.

In untreated systems, dirt can accumulate in multiple places throughout the system. Studies and practical experience show that magnetite in particular, leads to greatly reduced energy efficiency and therefore higher energy costs. Ensuring quick and efficient dirt removal is essential. Spirotech offers an extensive range of SpiroTrap dirt separators from small brass solutions to heavy duty steel units, especially designed for the removal of dirt.

A SpiroVent deaerator should always be installed at the hottest point within a system. In the case of a heating system, for example, this is the point where the water exits the boiler. In the case of a cooling system, it is in the return before the chiller unit. When installed in the correct location a SpiroVent has the capability to deaerate the entire system as it can make the water absorptive.

Pumps

Grundfos Magna PumpGreenheat UK stock pumps to boost your domestic and commercial water pressures.

Our heating and hot water system engineers can supply, install and maintain additional components, such as pumps installed on the system. Pumping systems can be designed and fabricated to your requirements to raise the water pressure to ensure you get the most out of your hot water system.

We work closely alongside the global leaders in Pump technology, Grundfos and carry in stock a widfe variety of their products for various applications. Offering, simple, cost and energy efficient pumps with simplicity and reliability is what the Grundfos name and brand have been built upon.

The MAGNA3 pumps are a range of small, medium and large circulatory pumps fitted with electronically controlled motors based on permanent magnet (PM) and compact stator technology.

The MAGNA3 will then analyse the heating system demands and find the optimal setting. It will then continuously adjust its operation to changes within the system demand. The result is optimal comfort and minimum energy consumption.

The Grundfos MAGNA3 circulator pumps are designed for circulating liquids in the following:

  • Heating systems
  • Air-conditioning and cooling systems
  • Domestic hot-water systems
  • Ground source heat pump systems
  • Solar-heating systems

The ALPHA3 has a built-in two-way communication system, which connects to the intuitive Grundfos GO Remote app. This enables you to easily exchange information between the pump and your smartphone. From the moment the circulator is installed and connected, all pump operation, including setup wizard, can be controlled on your smartphone (iOS and Android). Pump settings can be changed quickly and easily. And you get access to all relevant data, such as flow, pump performance, work log history and weekly running schedules, as well as warnings and alarms. So knowing exactly how the pump runs has never been easier. In addition, you can balance an entire heating system through the GO Balance app, with real-time calculations of the flow required in your radiator and underfloor heating systems. A step-by-step guide takes you through the whole process of hydronic balancing all the home’s radiators and underfloor heating zones.

In addition to Grundfos we also stock the Smith’s EP ES2 circulator pump range. This a highly efficient and extremely powerful pump, yet is small in size and almost silent. It is also backed with a 5 year warranty for added peace of mind. Amongst the features this pump has, it is unique in offering automatic airation – this means the pump will detect and clear air once detected inside the system.

Flexcon 110 – 1000

For sealed heating installations (acc. to EN12828) and chilled water (cooling) installations.
When the temperature in the installation rises, the system water will expand. The ‘expansion water’ is stored temporarily in the expansion vessel to keep the pressure in the installation at the correct level.

We believe Flamco offer the best expansion vessels thanks to their groundbreaking technology. Extremely low permeability of the diaphragm ensures that pre-charge pressure is maintained for a long time. The flexible diaphragms with rolling action are preformed and, in contrast to a bag type bladder, prevent stretching so that their properties are preserved over the long term. 

The unique clench ring construction clamps the diaphragm between the two vessel halves. This not only ensures a perfect seal but also prevents mechanical damage of the diaphragm during use (load distribution over the entire clamping area and not at 1 suspension point). The gas side is filled with nitrogen, and not with air, so that corrosion is prevented and the pressure loss is even more limited.

Flamcovent Clean Smart F – 16.0 bar

Optimum air and dirt separation combined with energy efficiency.
For use in sealed heating and cooling systems.
Air and dirt separators protect the boilers, pumps and fittings from damage caused by the deposit of dirt particles, increase comfort and improve the yield. Air and dirt separators also offer benefits in the event of application in old systems or when an open system is converted to a closed system.

Increases comfort and yield.Prevents deposit of dirt particles in the boiler.The removal of air and dirt from the system water extends the service life of pumps, control equipment and other system accessories.
The new steel Flamcovent Clean Smart air and dirt separators remove even the tiniest microbubbles and minuscule dirt particles from the system water. The Flamco Clean Smart performs 60% better than conventional air and dirt separators whilst the flow resistance has been reduced to a negligible level.

With flanged connection according to EN 1092-1 PN16.
