• Automatic AirVents - SpiroTops

  Automatic AirVents – SpiroTops

  The SpiroTop is a fully automatic air vent, as installation fluid functions best when it contains as little air as possible. In an installation, air gathers at the highest points, which can disrupt the flow or even stop it completely. The SpiroTop removes this air in a fast and effective manner, without the need for maintenance.

  Advantages:

  • High venting capacity
  • The large distance to the water (at least 40 mm) prevents contamination of the air valve. This contamination is one of the most important causes of leaks.
  • The ½” connection prevents pipette effect.
  • Wide range, suitable for various pressures and temperatures.

   

  Reliable

  The SpiroTop is a reliable automatic air vent that proves its worth time and time again, and not only when preventing air inclusions in an installation. When an installation is drained, the SpiroTop ensures that the aeration is fast and reliable.

• Dirt Separators - SproTrap

  SpiroTrap – Dirt Separators

  The SpiroTrap removes dirt particles from installation water. This is important, as even the smallest particles can still cause huge problems in an installation. The SpiroTrap dirt separator is much more effective and low-maintenance than a filter, as a filter becomes blocked, resulting in a large pressure drop. Moreover, replacing a filter often is a difficult job whereas draining the SpiroTrap only takes a few seconds. With the SpiroTrap, malfunctions, wear and tear, and Maintenance are proactively reduced.

  Advantages:

   

  • Also removes minute dirt particles (from 5 microns)
  • Removes dirt while the system remains in operation
  • Minimal, constant pressure drop
  • No shut-off valves or bypass required
  • Wide range in pressure levels, temperatures and materials

   

  Low Flow Resistance

  The SpiroTrap dirt separator has a very low and constant flow resistance. Furthermore, the dirt collected does not affect the SpiroTrap’s operation. The SpiroTrap comes with a drainage tap to remove the dirt, which only has to be used once in a while thanks to its large dirt collection capacity. SpiroTrap dirt separators are available in brass and steel.

• Combined Air & Dirt Separators - SpiroCombi

  In line Combined Deaerator and Dirt Separator;

  These units must always be installed at the hottest point of the system to starve the system water of air and so make the circulating water absorbtive. From this point the water can only cool down. As the water passes through the system, it cools down so any air pockets that are trapped above the flowing water [e.g. in radiators], begin to be absorbed by the water. This is the physics of water as Henry’s Law of absorbtion of gases in liquids, evolved in 1803, well before H&V came into being.

  The simple analogy is that as water is a natural element it must retain it’s natural characteristics at whatever temperature and pressure that it prevails under. When water is heated a proportion of air is driven off, but when it cools it requires to replace the driven off air from wherever it can.

  The air/water returns to the heat exchanger, the heat input then drives off this air that has been absorbed and this air is then released in the body of the deaerator.

  Eventually all air pockets are totally removed and the system water continues to become deaerated to such a point that no air can be released in the circulating system water.

  The inclusion of the Dirt Separator into the common body enables any circulating particles of dirt to be removed. A standard in line Y-type strainer normally has perforations in the screen of around 1,600µ, but the byproducts of corrosion are normally in the range of 0.5µ and up to around 100µ. Therefore these will continually re-circulate and cause maintenance problems in pumps, heat exchangers, radiators, control valves and the like. The main issue is that a Deaerator must be installed at the hottest point.

• Thermal & Vacuum Degasser SpiroVent

  SpiroVent – Deaerators

  If air is not sufficiently removed from the installation fluid, many inconveniences and issues arise which cannot be prevented by manual venting every now and then. However, Spirotech has the ideal product to remove even the smallest air bubbles from the installation water: the SpiroVent micro-bubble deaerator. At the core of this product is the Spirotube, which removes circulating air and trapped air bubbles from the water in a highly effective manner.

  Optimum effect without pressure drop

  The SpiroVent is placed in the full flow, but barely affects the pressure at drop all. We have a wide range of SpiroVent deaerators available. The SpiroVent is available in both brass and steel, and comes in many variations as regards pressure and temperature.

  Advantages of SpiroVent Deaerators

   

  • Effectively removes the circulating air and micro-bubbles
  • Removes trapped air
  • Much faster commissioning, and removes the need for manual venting
  • Minimal, constant pressure drop
  • No unnecessary standstill
  • Wide range in pressure levels, temperatures and materials

  Spirovent Superior – Vacuum Degassers

   

  The Spirovent Superior is a fully automatic Vacuum Degasser for heating, cooling and process installations. This device temporarily subjects part of the installation fluid to low pressure or vacuum. As a result, the air dissolved in the fluid is released and removed from the system. Thanks to the electronic, independent control system, reading system information is a breeze.

  Advantages:

   

  • Removes the dissolved gases; absorbative fluid also ensures that trapped gas bubbles are removed.
  • Plug & play, and can be calibrated very quickly.
  • Energy-efficient thanks to the SmartSwitch.
  • Automatic degassing, filling and pressure maintenance.
  • Protected against unwanted filling.
  • Ideal for low-temperature systems, such as heat pump systems and floor heating installations.
  • Can be used on a wide range of installations.

   

  Easy installation

  The SpiroVent Superior is supplied ready-to-use, complete with flexible connection tubes with gland nuts. Mounting, connecting and putting the device into operation is very easy.

  When to use Vacuum Deaeration?

  In installations with many branches and low flow rates. For small temperature differences between supply and return. A Vacuum Degasser is not limited by the fluid temperature.

  If a deaerator cannot be mounted on the installation for practical reasons. A Vacuum Degasser can be connected to almost every part of an installation.

  Dirt Separators in these installations will obviously have to be stand alone products.

  SpiroVent RV2 Domestic Deaerator allowing Horizontal, Vertical and even Diagonal Installation!!

  As a result of the many positive reactions to the swivel connector on the SpiroTrap dirt separators versions MB2 and MB3, a SpiroVent deaerator is now also available in this edition. The SpiroVent RV2 is a fully universal domestic deaerator. Like all other SpiroVent versions, it easily and effectively removes circulating air and micro bubbles from heating systems.

  The connection base can be rotated, allowing the unit to be installed in horizontal, vertical and even diagonal piping. Practice of the SpiroTrap with such a connector proves that the added convenience goes hand in hand with the familiar product quality and reliability.

• Pressurisation with Vacuum Degasser & in line Dirt Separator - SpiroPRESS & SpiroTRAP

  Pressurisation with Vacuum Degasser & in line Dirt Separator;

  By quite simple modifications to the Pressure Differential Deaerator the units can easily be adapted to incorporate Pressurisation, all in one compact unit.

  All that is really required is a cold water makeup connection, a pressure switch and modified controls. An additional cold water make-up solenoid is installed so that when the there is a low pressure signal from the pressure switch, the controls of the deaeration phase are overridden by the need for water make-up.

  When the pressure has been stabilized then the controls switch back to the deaeration phase. Much mystique surrounds pressurisation, but to keep simplicity to the fore, all that is really required is to ensure that the expansion vessel (s) are slightly over-sized. The need for pressurisation then is extremely rare after initial commissioning.

  Don’t forget that additional make-up water weakens chemical concentrations! The S6AR2 has the facility for a second pump if desired.

  In line Dirt Separators – SpiroTrap

  The SpiroTrap removes dirt particles from installation water. This is important, as even the smallest particles can still cause huge problems in an installation. The SpiroTrap dirt separator is much more effective and low-maintenance than a filter, as a filter becomes blocked, resulting in a large pressure drop.
