HAVEN SUPPLY AND EXTRACT TERMINALS SELECTION GUIDE INTRODUCING HAVEN SUPPLY AND EXTRACT TERMINALS Haven Supply and Extract Terminals overcome challenges often encountered when ensuring all occupants receive the right supply of fresh air, even when building layouts are changed. With occupant health and well-being at the core of our thinking, Haven Supply and Extract Terminals have been developed to allow the provision of the best air quality possible for each individual – without resorting to extremes of personnel segregation. This led us to consider how we could set new industry standards by...

HAVEN SUPPLY AND EXTRACT TERMINALS SELECTION GUIDE TERMINAL QUANTITY GENERAL CONCEPT GENERAL OFFICE / CALL CENTRE INDIVIDUAL OFFICE HIGH DENSITY CALL CENTRE The illustrations below represent typical systems found in work and public spaces – with each occupant’s location considered. We can apply the overall concept to other room types and layouts. The Haven Supply and Extract Terminals supply air terminal (HTS) range offers a number of formats based on nominally providing one directionally adjustable supply outlet (SO) per individual occupant. Haven Supply and Extract Terminals create a fresh...

HAVEN SUPPLY AND EXTRACT TERMINALS SELECTION GUIDE TERMINAL SPECIFICATION SPECIFICATION Haven T S 4/9/12 Supply Terminal GENERAL The Haven Supply Terminal shall be suitable for supply ventilation rates of 40 – 120 l/s* via the specified quantity of independent supply ports, each with 360 degree directional adjustability. The air shall be discharged from each port at an initial velocity not exceeding 1.5 m/s, and at an initial angle of 45 degrees from the horizontal. The terminal shall include means of flow equalisation. The non-combustible terminal housing shall be constructed from heavy gauge...

HAVEN SUPPLY AND EXTRACT TERMINALS SELECTION GUIDE DIMENSIONAL DRAWINGS EXTRACT TERMINAL HTE1/2/3 HORIZONTAL FACIA EXTRACT TERMINAL HTE1/2/3 DIAGONAL FACIA By using fine particulate or chemical filters in the Haven Terminal unit or in the Haven inline filter module, treatment is provided for residual external and system-based contaminants to the greatest practical extent. Haven Supply and Extract Terminals provide an efficient means of providing high specification filtration to provide maximum protection to the building occupants. Classification of contaminants and selection criteria for filtration...

HAVEN SUPPLY AND EXTRACT TERMINALS SELECTION GUIDE SUPPLY AIR CLASSIFICATION As a starting point, the following approach is suggested. UP 1 applies where the supply of air fulfils the WHO (2005) guidelines limit values S and any National air quality standards limit values or regulations with a factor x0,25. UP 2 applies where the supply of air fulfils the WHO (2005) guidelines limit values S and any National air quality standards limit values or regulations with a factor x0,5. UP 3 applies where the supply of air fulfils the WHO (2005) guidelines limit values S and any National air quality standards...
