Frenger Systems limited® is a wholly owned subsidiary of FTF Group. Frenger® is a world-renowned specialist designer and manufacturer of space conditioning products for indoor climate/environments.

Frenger® they has extensive experience dating back over 80 years and are at the forefront for the design, development, and manufacture of water driven cooling and heating technologies.

UK Office & Factory

Manufacturing of their products take place in-house at their UK Head Office and Technical facility in Derby, with the state-of-the-art facility allowing for the manufacturing capability required to deliver the most complex of bespoke solutions.

Included in their facilities are the latest bespoke manufacturing machinery as well as a dedicated powder-coat paint plant to paint all of the components of the Multi-Service Chilled Beams.

At their UK head office we have significantly invested in their in-house testing facilties. Frenger® have 3x Climatic Test Laboratories, 2x Photometric Test Laboratories, and 1x Acoustic Test Laboratories to allow for project-specific in-house mock-up testing, allowing the client to fully asses the proposed system and determine the resulting Indoor Air Quality (IAQ) and Thermal Comfort conditions.

Testing Laboratories

Each in-house Climatic Laboratory has internal dimensions of 6.3 x 5.7 x 3.2m and includes a thermal wall so that both core and perimeter zones can be modelled.

Frenger® employ the use of state-of-the-art thermography technology with FLIR® thermal imaging cameras, which help to determine the most efficient way to improve project specific installations, as well as further the development of their spatial conditioning technology.

The two in-house Photometric Laboratories are used to evaluate the performance of luminaires. To measure the performance, it is necessary to obtain values of light intensity distribution from the luminaire itself.

Luminaire outputs are measured using their integrating sphere for smaller luminaires or their large integrator room for large fittings and Multi-Service Chilled Beams. For other methods, Frenger® use traceable calibrated radiant flux standards for absolute comparisons.

The in-house Acoustic Test Laboratory is a hemi-anechoic chamber which utilises sound absorbing acoustic foam material in the shape of wedges to provide an echo free zone for acoustic measurement.

The height of these acoustic foam wedges has a direct relationship with the maximum absorption frequency, therefore they had the wedges specifically designed to optimise the sound absorption at the peak frequency normally found with their Active Chilled Beam products.


Frenger® employs professional project managers, designers, mechanical and electrical engineers; the company has a reputation for delivering complex projects on time, within budget and to specification.

To meet architectural expectations, Frenger® employs in-house 3D computer generated modelling using various different software design packages including Solidworks, Revit and can even produce building fly throughs.
