A chilled beam is a type of convection HVAC system designed to heat or cool large buildings or office spaces. Beehive design and produce two types of chilled beam coils - passive or active.
Passive chilled beams use our standard fin and tube coils, sometimes contained in a housing that will eventually be suspended from the ceiling. Some passive systems rely solely on convection whilst there is also a "radiant"/convective passive type which cools through a combination of radiant exchange and convection which can provide higher thermal comfort levels depending on the system.
When in operation, standard passive systems work by cooling the surrounding air around the chilled beam, which then falls to the floor and is replaced by warm air from the room which rises towards the ceiling - creating a convective air motion to cool the room. This allows passive chilled beams to provide space cooling without the additional expense of installing fan motors.
Active beam designs use ducts to push (or induce) air towards the unit effectively increasing its heating or cooling capacity. This induction process allows an active chilled beam to provide more cooling capacity than a passive chilled beam in certain applications.
Both passive or active beams can be supplied as 2 or 4 pipe versions with or without integral heating circuits to suit your requirements.
The chilled water system must be designed to prevent the temperature of the water supplied to the heat exchanger from falling below the room dew point to ensure that the beam provides sensible cooling only. Chilled beam systems should not be designed to condense.
Don’t forget to clean your coils regularly to get the best performance and life from your unit!
"At Beehive, we have extensive experience of manufacturing chilled beam coils and our products are used in projects all over the world."
Water coils are the most straight forward heat exchanger we manufacture but also have the widest variety of uses as chilled water, low pressure hot water (LPHW) units, fan coils, heaters, chilled beams (with or without heating circuits), glycol coils and many more different applications.
Whether the brief is for comfort cooling, specialist multi-stage DX systems or industrial/commercial projects - we can help by selecting units to meet a wide range of temperatures from HVAC to low temperature freezing applications.
Condensing is the act, or practice, of condensation in any form. Condensation is the change of the physical state of matter from gaseous phase into liquid phase, and is the reverse of evaporating.

We have extensive experience in manufacturing CO2 Evaporator coils of all types and have been doing so for many years. We can assist with design of your coil to ensure it meets the latest BS EN 378 requirements whether you have a sub or trans-critical CO2 system.
Steam coils are used in both industrial and HVAC applications and are used to heat air when steam is available. Finned tubes are almost always used in steam coil applications and this type of coil makes use of the latent heat that is released by the steam when it condenses so it is a very effective way of heating air.
All of our units are manufactured to the current PED standards and supplied with a comprehensive warranty and we are also proud to hold the latest ISO 9001:2015 accreditation - enhancing both the quality of our service as well as our products.
