Air Conditioning
JJ Ventilation offer a range of air conditioning products and services from several major manufacturers to ensure we are able to offer state-of-the-art solutions utilising the very latest technologies.
We offer systems ranging from basic split systems, multi-split and variable refrigerant flow (VRF) systems all utilising the latest environmentally friendly R410A and R407C refrigerant gasses.
Cassette Units
Designed to be installed in most types of suspended ceiling, the standard ceiling cassette is ideal for businesses and commercial premises. Fresh air ventilation can be introduced through the controllable cassettes louvres. There is also a branch duct facility for air distribution to adjacent areas. The combination of these features gives occupants total control over air movement within the room via an easy to use programmable controller.
The four-way cassette is compact, can be concealed in most ceiling voids, is supplied with a long-life washable filter and is very effective at creating even climatic conditions over a large area.
Wall-Mounted Units
Stylish and slim, elegant wall mounted units complement any internal décor and are suitable for a variety of applications, i.e. small rooms and offices and areas without suspended ceilings. The range of wall-mounted air conditioners provides powerful cooling and heating air flows which gradually adjust the room temperature to the required condition in the minimum time and at maximum efficiency.
VRF
The VRF, or variable refrigerant flow system, is a versatile means of linking a number of indoor cassettes and wall-mounts to a single external condensing unit. Among the advantages of this system are reduced installation costs, external space saving and improved external aesthetics. The system is also very energy-efficient as the refrigerant flow is constantly varied to suit the exact user requirements.
Service and Maintenance
JJ Ventilation also offer service and maintenance contracts in order to maximize service life and ensure the equipment always functions at optimum efficiency in accordance with the manufacturer’s instructions and refrigerant gas legislation.
