CHILLED BEAMS & FAN COILS Flexibility in the Beehive


Beehive Coils manufactures both chilled beams and fan coils. Here, we take a snapshot of what the company is all about.

eehive Coils was established in 1968, and has been continually striving to off er its customers more choices, better lead times and competitive prices. With over half a century of experience, the business prides itself on its expertise in refrigeration and HVAC equipment design and manufacture. Output is currently well over 100,000 units every year with a variety of specifi cations and sizes being produced. Flexibility is one of the company’s core values, which is why it has invested in a wide range of tooling types and confi gurations in order to ensure the customer gets the best product for the job.


The standard ranges that Beehive manufactures include water fan coils, DX units, condenser coils and more. However, with a view to developing markets over the years, the company has branched out into many diff erent areas of the HVAC industry including the manufacture of pack housing units, complete with coils – and high-pressure CO2


coils to suit


the latest technology in supermarkets today. Beehive has a full in-house design team capable of designing new units to meet particular specifi cations and provide technical backup, if required. In addition to manufacturing, the company also off ers the capability of producing replicas, and repairing existing units.


Passive chilled beam


Fan coils Fan coils are one of the most common heat


exchangers that Beehive manufactures, and can be made in a wide variety of shapes and sizes. Generally, they are produced with combined heating and cooling abilities, but these can be separate if required. Fan coils can be used in many diff erent applications such as chilled water, low pressure hot water (LPHW), heaters and chilled beams. The standard construction of fan coils that Beehive manufactures is with copper tubing and aluminium fi ns – but there are several variants on off er in terms of materials such as coated fi ns, copper fi ns, heavy walled copper tubing. In addition, there are options on case material which include galvanised, stainless, aluminium,

brass, or copper – all in a variety of grades to suit any application.


Chilled beams Beehive manufactures both passive and active


chilled beams.


Passive chilled beams use standard fi n and tube coils, sometimes contained in a housing that will eventually be suspended from the ceiling. Some passive systems rely solely on convection, while 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


Active chilled beam


surrounding air around the chilled beam, which then falls to the fl oor 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 eff ectively 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. Beehive has invested signifi cantly in its technical drawing offi ce by installing the latest CAD Solidworks software. This means that the company not only manufactures using the highest standard drawings but can model units in 3D, or send copies to the customer so that they can be totally happy with every aspect of design before production. Staff training is important to Beehive to


ensure the safety of workers and consistent quality of products. With this in mind, the company is F-Gas registered allowing its engineers to work safely with fl uorinated gases and hermetically sealed systems. It has also held BSI Certifi cation ISO 9001:2015 – as it is currently termed – for 30 years, and all units are manufactured to the current PED standards.
