KMSR bypass terminal units Description The Koolair KMSR boxes are bypass terminal units used in single-duct, low-velocity systems where a volume control damper cannot or should not be used in the fan. The KMSR receives constant air flow, supplies a part of this air to the room to be conditioned and reroutes the rest to the return duct. As a result, the equipment acts as a constant-volume unit, but the room to be conditioned receives variable flow air as needed. KMSR A typical application consists of using the KMSR with standalone equipment where, for system economics and to avoid frost in...

(*) OVAL (circumference equivalent to round section) Identification: Example: KMSR-500-1 Bypass supply unit. Size 500 with rectangular discharge outlet. If necessary, the side where the actuator should be mounted should be defined, as viewed from the air inlet side. If there is more than one discharge outlet, each discharge has a manual damper to balance the pressure loss of each of the supply circuits.

Selection tables The following tables (1 to 8) contain all the data necessary for correctly selecting the KSMR terminal units. Data common to all tables: Ø (mm): Diameter of standard round inlet connection to box. Minimum inlet pressure to KMSR equivalent to pressure loss of box with the damper completely open. Q(m /h) (l/s): Air flow rate for which the unit is to be selected. Determination of the sound power regenerated by the KMSR. This table lists the sound pressure level in the room, due to the noise regenerated by the KMSR unit, in db(A) for various air flow rates. To obtain these...
