Angle configurations are typically Installed at the top of a steam radiator, for the purpose of venting trapped air by means of steam displacement

Durable chrome-plated finish is both decorative and functional

all configurations are plated and are more resistant to moisture staining than unplated vents

The adjustable T-90A is capable of slow, medium or fast venting, to accommodate extreme variations in room temperatures, such as colder rooms with radiators located farthest from the boiler, to hotter rooms with radiators located closest to the boiler

Straight configurations can be installed onto radiators or within the system, for branch or main venting functions (multiple vents may be required for this type of installation)

The DISCAL® air separator is used to continuously remove the air contained in hydronic circuits of heating and cooling systems

The air discharge capacity is very high

They automatically remove all the air present in the system down to micro-bubble level with low head loss due to the special internal shape of the separator body

Flow direction of the DISCAL air separator is bidirectional

flow in either direction is permitted

The circulation of fully de-aerated water enables the equipment to operate under optimum conditions, free from noise, corrosion, localized or mechanical damage

Micro-bubbles, fusing with each other, increase in volume (get larger) until they become large enough to rise to the top where they are automatically released

Anti-rotation/anti-vibration pinned float: Creates space between float and air vent wall to prevent float hang-up from debris or variations in separator installation orientation

Large-diameter chamber: Slows fluid flow dramatically. Combines with concentric, sharp-edged mesh design to cause micro-bubbles to efficiently collect and coalesce. Highly effective automatic air elimination

Anti-corrosion coalescing mesh: Constructed of glass-filled nylon. More resistant to dissolved oxygen and acidic fluids than plated metals

Robust stainless steel float linkages: Reliable float alignment even during turbulent conditions such as filling from bottom

Corrosion resistant: All components highly resistant to hydronic chemical additives or unstable pH fluid
