Active Chilled Beams

Frenger designs, manufactures and supplies a range of active chilled beams. They draw upon high performance technologies and patented design features to deliver efficient cooling to commercial, educational and healthcare environments.

The cooling batteries that characterise Frenger's range of active chilled beams enables the units to deliver unrivalled levels of cooling capacity with a given air volume. The units are so efficient that they can provide in excess of 1050 watts per meter with fresh air supply of 26 ltrs/sec/m (please note however that 23 ltrs/sec/m is the recommended air volume for occupancy comfort).

Compact® is one of Frenger's latest range of high performance Chilled Beams. Energy efficiency has been a key driver for such advancements in Frenger's Chilled Beam Technology.

Compact is only 133mm deep and can achieve up to 1092 watts per meter total cooling (based on 10dTK and 26 ltrs/sec/m for a 1.8m long beam, supplied at 16°C with a 100Pa).

The Compact beam contains a number of Patent pending performance enhancing features and as can be expected from the Frenger brand, the Compact beam is designed to be easily tailored to suit the unique parameters of individual project sites, for the optimum product / system efficiencies. This is partly achieved by the "burst nozzle" arrangement that not only encourages induction, but also reduces noise. Given the size and amount of burst nozzles being appropriately quantified for each project, this provides consistent jet velocities, equal distribution of the air discharge and continuous induction through the heat exchanger (battery). There are no dead spots due to plugging back nozzles from a standard pitch or having to adjust the pressure in the system to suit the amount of open standard nozzle sizes as associated with many competitors' active beams as dead spots and / or reduced jet velocities decrease their cooling capacities / efficiencies.

Eco is one of Frenger's latest range of high performance Chilled Beams. Energy efficiency has been a key driver for such advancements in Frenger's Chilled Beam Technology.

Eco is 227mm deep as standard and can be increased to 267mm deep for higher air volumes. Eco and can achieve 1016 Watts per meter total cooling (based on 10dTK and 25 ltrs/sec for a beam supplied at 16°C with a 100Pa).

The Eco beam contains a number of Patent pending performance enhancing features and as can be expected from the Frenger brand, the Eco beam is also designed to be easily tailored to suit the unique parameters of individual project sites, for the optimum product / system efficiencies. This is partly achieved by the "burst nozzle" arrangement that not only encourages induction, but also reduces noise. Given the size and amount of burst nozzles being appropriately quantified for each project, this provides consistent jet velocities, equal distribution of the air discharge and continuous induction through the entire length of the heat exchanger (battery). There are no dead spots due to plugging back nozzles from a standard pitch or having to adjust the pressure in the system to suit the amount of open standard nozzle sizes as associated with many competitors' active beams as dead spots and / or reduced jet velocities decrease their cooling capacities / efficiencies.

Ultima® is one of Frenger's latest range of high performance Chilled Beams. Energy efficiency has been a key driver for such advancements in Frenger's Chilled Beam Technology.

Ultima is only 208mm deep and can achieve 1050 watts per meter total cooling (based on 10dTK and 26 ltrs/sec/m for a 2.4m long beam supplied at 16°C with a 100Pa).

Halo is one of Frenger's latest range of high performance Chilled Beams. Energy efficiency has been a key driver for such advancements in Frenger's Chilled Beam Technology.

Halo is only 230mm deep and can achieve up to 1463 watts total cooling (based on a 1.2m long beam with a 10 dTK between room and mean water temperature and 44 ltrs/sec of air 16°C with 100Pa). The Halo beam contains a number of Patent pending performance enhancing features and Registered Designs for aesthetic enhancements, all as can be expected from the Frenger brand.

These high-capacity active chilled beams have a small footprint and as such have become increasingly popular as they can free up ceiling area whilst still handling significant heat gains and heat losses. However, the challenge has been to meet these demands whilst still delivering high levels of occupancy comfort. Frenger's Halo active chilled beam meets these challenges with its unique, true 360° air discharge characteristic with concealed air discharge veins.

Cornice is one of Frenger's latest range of high performance Chilled Beams. Energy efficiency has been a key driver for such advancements in Frenger's Chilled Beam Technology.


Cornice is only 340mm deep and can achieve 630 W/m total cooling (based on 10dtK and 4.86 l/s for a beam supplied at 16 °C with a 100Pa).

The Cornice beam contains a number of Patent pending performance enhancing features and as can be expected from the Frenger's brand, the Cornice beam is designed to be easily tailored to suit the unique parameters of individual project sites, for the optimum product / system efficiencies. This is partly achieved by the "burst nozzle" arrangement that not only encourages induction, but also reduces noise.

The Bulkhead Active Chilled Beam is one of Frenger’s latest range of high performance Chilled Beams. Energy efficiency has been a key driver for such advancements in Frenger’s Chilled Beam Technology.

The Bulkhead beam contains a number of performance enhancing features as can be expected from the Frenger brand. The beam is designed for discreet installation into bulkheads, primarily for use in hotel bedrooms.

All induced / recirculated room air is via the return air grille which conceals the inside workings of the Active Beam, from an occupant which is resting in bed for example. The Bulkhead beam discharges its reconditioned air (which is a mixture of fresh air and recirculated air) at high level out of the top of the unit which then entrains across the ceiling (dependent upon discharge mounting height relative to ceiling) before gently dispersing and mixing with the room air.
