BOSS Air and Dirt Separation Brochure (1)

AIR AND DIRT SEPARATION

vBOSS Minivent is designed for use on heating and chilled systems with continuous working pressures up to 10 bar(g) and 90C. The BOSS Minivent should always be sited where air is known to collect or at the highest points of the system. This allows the unit to vent air efficiently.

The BOSS Minivent floats in the water and keeps the venting valve closed. When air is collected in the BOSS Minivent, the water level will drop and the venting valve will open. The collected air will escape, causing the water level to rise and the venting valve to close. This process continues as long as air is collected in the BOSS Minivent. The air cushion in the upper part of each BOSS Minivent protects the valve seat against contamination.

Working temperature range -10C to 90CMaximum working pressure 10 bar at 90C

Also available BOSS Flexvent H which has a " right-angled connection which can be mounted directly onto radiator sockets.

Ideal for Commercial Heating and Air Conditioning Systems. A high capacity unit which removes rising air bubbles through a specially designed float operated valve.

vBOSS MB Air Separators are used for the total removal of free air from Central Heating and Air Conditioning systems. The BOSS MB Air Separators are based on a special method of separating gases from fluid (water). The process uses special fillers which are called PALL rings.

A BOSS Air Separator fitted in the right place in the installation can remove all air which is present in the water of the system in the form of small bubbles and micro bubbles. It can also remove all air which is dissolved in the water of the central heating system.

INFORMATIONThis is how efficient PALL rings are:The construction is such that all fluid comes into contact with the total adhesion surface of the PALL rings. Microscopically small gas bubbles in the fluid will adhere to the contact surface of the PALL rings. The process of coalescence means that the microscopic bubbles will grow into larger bubbles.The larger gas bubbles will have sufficient floating power to be separated and rise into an air chamber.

AIR & DIRT SEPARATORS

BOSS MBC Air & Dirt Separators have been developed to remove air and persistent dirt particles. The relatively heavy dirt particles sink to the bottom and these particles cannot get back into the system. The sediment is released through the drain cock on the bottom of the Air & Dirt Separator.

Suitable for use on heating and chilled systems. The BOSS MBC should ideally be installed in the hottest part of the system (typically the flow pipe from the Heat Exchanger). Features PALL ring technology.

BOSS DI Clean is a high efficiency dirt separator. Suitable for use on heating and chilled systems. The BOSS DI clean should ideally be sited in the return pipework to prevent the build up of silt or debris within the heat exchanger. This allows the system efficiency to remain at its commissioned efficiency.

Effective removal of particles from 32 microns down to 20.
