This APACS system illustration shows various
Argon air outlets designed to meet all needs of a total air conditioning
system. The Floor Air Terminal can be supplied with heat to cover
window and wall heat loss. The illustration shows how particles lighter
than air, such as bacteria, mold, etc., are carried away and not recirculated,
creating a cleaner environment. |
