HOW IT WORKS As with all air curtains from Biddle the DoorFlow uses Biddle’s proven, patented rectifier to supply conditioned air at low speed with minimum turbulence, ensuring the air stream reaches the floor and doesn’t escape to the outside. Comfort within the entrance area is therefore enhanced without any energy wastage. APPLICATIONS Available in a variety of paint finishes, the DoorFlow has a minimalist style, being designed to look good in all types of entrance environment – from fashionable boutiques to schools and colleges. Modular in nature, any number of units can be joined together...

CONTROLS E NERGY SAVING ECONTROL The new ECONTROL will ensure air curtain performance is optimised whilst minimizing energy usage. Connecting the ECONTROL to DOORFLOW couldn't be easier-just plug one end of the cable into the air curtain and the other end into the controller. INSTALLATION AND MAINTENANCE Carefully developed to minimise maintenance, a purpose designed coil/heater battery reduces the build-up of dust and debris between the coil fins to such an extent that filters are no longer necessary. Having no filters means the DoorFlow doesn’t just offer minimal maintenance but also provides...

C ONTROLS SCHEMATIC AND/OR CORRECT CHOICE OF UNIT ESSENTIAL FOR PERFORMANCE F or optimal functioning of the DoorFlow, selecting the right type of unit(s) is essential. If an air curtain has been selected well it is able to protect the entire width and height of the door opening. The unit must have sufficient heating capacity to be able to bring incoming cold air to a comfortable temperature. 1. INSTALLATION HEIGHT AND WIDTH INHIBIT HEALTHY Based on the installation height (from floor to the bottom of the unit) and the door width, it is easy to select the right air curtain (see selection table)....

SPECIFICATIONS CONTROL & OPERATION adjusting heat output and fan speed the By ECONTROL ensures air curtain performance is optimised whilst minimising energy usage. It is connected to the unit by a low voltage data cable with a RJ4/4 plug on both ends. Multiple units are also connected in this way. Cables are available in a variety of lengths. ELECTRICAL CONNECTIONS LPHW units are connected to the mains supply by a 2 metre cable. The 3-phase mains supply cable used with electric heated units enters the air curtain via a cable gland on top of the unit and is then connected to a terminal strip within...

TECHNICAL EXPLANATION TECHNICAL EXPLANATION The heating capacities of water units with the two row heating coil are based on a water range of 80/60°C with an air inlet temperature of 20°C, and with the four row heating coil on a water The sound data is based on the direct field, in a situation temperatures, the heating capacity should be multiplied by the factors in the table below. Closed door with an open door and a sound absorbing ceiling. range of 60/40°C with an air inlet temperature of 20°C. With different water and air inlet Acoustical "hard" ceiling The sound data for different situations...
