Chilled Beam – Active & Passive
The OKNI active chilled beam has been designed as a compact chilled beam, with a low built-in height; they have a high capacity and they are suitable for ventilation and cooling and for heating rooms of 2.4 to 3.5 metres high. The units have the same capacities, but vary in width.
The closed units introduces the supply air on two sides and its highly efficient blow-in effect means it can be fitted in offices in the middle of the rooms parallel to the facade.
The choice of various nozzle types enables an optimum combination of ventilation air and cooling capacity in every situation.
Flexible Hoses and Connectors for Chilled Beams
ecoHVAC can also supply Flexible Hoses and Connectors to suit your Chilled Beam application.
The hose consists of a 304 grade stainless steel braided outer casing and an inner tube of Ethylene Propylene Diene Monomer (EPDM) for Chilled Water applications. They are supplied with either flat seat or BSP fittings.
The nominal length of the hose is 500mm (as standard) but can be supplied in lengths of 750mm or 1,000mm. Other lengths are available on request.

Constant Volume Damper – VCMR
The VCMR is a mechanical constant volume damper. The damper is designed to maintain the design volume independent of inlet pressure. The design volume is easily set by adjustment of the external sliding scale. The operating range of the damper is 50 – 1000 Pa (±10%).
The housing and damper are manufacturered from galvanized sheet steel and the damper shaft is manufacturered from stainless steel. The bearings are maintenance free.
The VCMR constant volume damper is not affected by the mounting position and can be mounted horizontally, vertically or on an angle. Each unit can be fully adjusted on site within its operating limits.

How Chilled Beams Work
A chilled beam is a type of convection HVAC system designed to heat or cool large buildings. Pipes of water are passed through a chilled beam either integrated into a suspended ceiling systems.
As the chilled beam cools the air around it, the air becomes denser and falls to the floor. It is replaced by warmer air moving up from below, causing a constant flow of convection and cooling the room. Heating works in much the same fashion, similar to a steam radiator.
