Complete climate system Since 2006 Biddle and Daikin have joined forces to provide a complete climate system for shops and public buildings. By combining Biddle air curtains with the highle efficient Daikin heat pump systems, a lot of energy is saved and comfort in the building is optimum. Maximum comfort Both visitors and personnel can enjoy maximum comfort during the whole year, under all weather conditions. This is the result of the efficient climate separation created by Biddle air curtains, while heat pump systems heat, cool or ventilate to provide a comfortable indoor climate....

A new wave in climate separation SR air curtains are the ideal solution for retailers and other end-users to combat the issue of climate separation across their outlet or office building doorway. The importance of accessibility to attract customers in the retail sector is wellknown, but with this free form of access through ‘open door’ trading, cold draughts and high-energy bills are often the consequence. High comfort and energy efficient Intelligent auto-active control and monitoring The autoThe SR technology has been improved to deliver active control is the next generation of controls....

Energy-efficient climate concept Biddle and Daikin supply a complete plug & play climate concept. Within this energy-efficient climate concept two different versions are available: the SRV and SRQ models. Complete SRV air curtain – climate system The climate system consisting of the SR air curtain, model SRV (1), Daikin VRV outdoor unit (2) and indoor units (3) supplies heating, cooling, ventilation and climate separation in one energy-efficient installation. By heating and cooling at the same time the heat extracted from the cooling systems can be extracted for the air curtain, thus...

Intelligent control and monitoring There are an extensive range of control options; touchscreen control (b-touch), remote operation and integration with a Building Management System (BMS). It is possible to monitor the energy performance and comfort levels remotely by means of the b-connect monitoring module. Connecting to a BMS is easy through a standard Modbus Protocol connection, whilst it is also possible to communicate via BACnet. All SR devices are fitted with Biddle's innovative autoactive control, the next generation of controls. Auto-active control Generally, installing an air...

Air curtain selectio Selecting the right air curtain is crucial in order to ensure the SR works optimally.

SR DX explanation of technical data data Because of the auto-active control of the SR DX air curtain the outlet temperature varies at all speeds, depending on the situation. The maximum heating capacity of the DX air curtains is the same as the heating capacity in the highest fan speed. Selection Daikin outdoor unit To determine the correct Daikin outdoor unit for model SRV, you need to add together the capacity indexes of all the indoor units. Sound The sound data is based on the direct field, in a situation with an open door and a sound absorbing ceiling. The sound data for different...
