Zephyr Cool EC
Recirculating air curtain
for shielding cool and unheated rooms
Zephyr Cool EC is suitable for the climatic separation of a cooled and an uncooled room.
Zephyr Cool EC is used wherever it is not desirable for warm air to enter sales or storage rooms. For example: in cool rooms, flower shops, butchers' shops and hospitals. Not suitable for wet rooms or rooms with large temperature differences. Installation-ready unit for different installation variants.
Connection-ready door air curtain unit for operation with recirculating air, without a heat exchanger. Zephyr Cool is an economical and effective solution for separating cold air and warm air. This results in considerable energy savings. The room temperature and humidity are also maintained at a relatively constant level, even if the door is open.
Self-supporting, powder-coated sheet steel housing. Screws are not visible. Available in RAL 9016 as standard (traffic white). Other colours are available. Inspection panel accessible from below, hidden behind the intake grille.
Intake grille in the same colours as the unit, consisting of a perforated plate with micro grille behind it (used as an intake filter) for easy maintenance. Discharge grille with steplessly adjustable discharge fin (natural anodised finish) for optimum airflow.
The micro grille is easy to clean without opening the unit – simply vacuum clean the intake grille.
Discreet secured access panel hidden on the lower side of the unit (hinges on one side) – easy to open.
The efficiency of the EC fans used by TEKADOOR is > 90% under partial load operation. This is 30–35% higher than for conventional AC fans. This does not just increase the efficiency, but also reduces the operating costs. The individually-driven EC fans with integrated motor protection can intake air in both directions. They have vibration-free bearings and are controlled using a PWM signal (pulse width modulation).
They do not just comply with Directive ErP, but actually exceed this standard.
Simple mounting thanks to the rivet nuts (M8) incorporated on the upper side of the unit and optionally-available assembly materials. In the standard version, the unit does not need to be opened for electrical connection. Connection terminals for the voltage supply, as well as the connectors for the control unit and parallel operation can be accessed from the outside.
Electronic TEKADOOR GTC EC control unit, multifunctional with touch display, including an optional ModBus interface
As standard, the 5-stage GTC 1 EC control unit includes a manual to automatic mode switch and a potential-free contact for enabling via any on-site BMS or BEMS. A choice of 5-stage or stepless fan operation is offered as standard. A maximum of 10 units can be connected in parallel. 20 m of preassembled, shielded data cable is also included as standard.
