Jet Nozzles

Standard Model:  JNZ

Jet nozzles are used for preference where the supply air from the diffuser has to travel a large distance to the occupied zone.

Product Description

Jet nozzles are used for preference where the supply air from the diffuser has to travel a large distance to the occupied zone.

This is the case in large rooms (halls, assembly rooms etc.), particularly when the distribution of air via ceiling diffusers is not possible or not practical. Here jet nozzles are arranged in the sidewall areas. When the temperature difference between the supply air and the room air changes, the supply air stream is deflected upwards (warm air) or downwards (cold air).The direction of the supply air flow is also affected by other influences such as local convection effects or draughts within
the room.

Cosmos Jet Nozzles are the ideal choice for distributing conditioned from ceiling diffusers is not possible or practical. Long throw jet nozzles provide optimum performance for air supply within large spaces such as in Connection Centre, Airport Terminals, Indoor Stadiums, Television and Movie Studios & Auditoriums. The nozzles are located within walls, Bulk Heads of columns to optimize supply air distribution.

COSMOS model JNZ supply nozzles are capable of delivering air to spaces where long distance penetration and low noise levels are required. Its nozzle type outlet suitable for spot cooling or heating, because its direction of air can be adjusted easily to suit one’s requirement.

Jet Nozzles can be turned through ±30 degree from its centre􀀂line axis and rotated 360 degree. Thus provide universal directional throw.

Selection Guide

First determine the total supply air quantity to be delivered the air-condition space, based on its heat load.

Then determine the number and location of the jet nozzles, based on the air distribution pattern and any constrains imposed by the building design.

Select suitable Jet Nozzles from tables below after determining Throw require (8m, 16m, 25m ). Terminals air velocity at the end of throw shown in the last column low velocity are best in auditoriums, Television, Movie studios while medium to high velocities can be tolerated in the airport & exhibition centers where occupants are moving about.
