Zephyr-Plus EC

The Store Classic


Zephyr-Plus EC
Shop Air Curtain


Zephyr-Plus EC is the tried-and-true classic for retail spaces, offering impressive versatility and high flexibility in integration. This ready-to-install unit is ideal for a wide variety of interior designs and supports effective air separation in entrance and sales areas.

The various installation options are particularly convenient: The Zephyr-Plus EC can be installed as a free-hanging unit, flush with the ceiling as a cassette, in a false ceiling with a slide-in connector, and, upon request, as a floor-standing unit. This allows the system to be optimally adapted to architectural and technical requirements.

A classic for modern retail concepts.
  1. Made in Germany
  2. Sturdy, self-supporting sheet steel enclosure with a high-quality powder coating; RAL 9016 as standard
  3. Installation Options: Free-hanging, flush with the ceiling as a cassette, recessed installation in a false ceiling with a slide-in fitting, floor-standing unit available upon request
  4. Easy to maintain thanks to the filterless micro-intake grille
  5. Aerodynamically Optimized Discharge Fin
  6. Various heating media are possible
  7. TEKADOOR Electronic Multifunction Control Unit; on-site control is optional

The efficiency of the EC fans used by Tekadoor is >90% under partial load, which is approximately 30–35% higher than that of conventional AC fans. This not only increases efficiency but also reduces operating costs. The individually driven EC fans with integrated motor protection feature double-sided intake, are mounted on vibration-free bearings, and are controlled by a PWM (pulse width modulation) signal. They not only comply with the ErP Directive but actually exceed this standard.

Easy installation thanks to rivet nuts (M8/M10) recessed into the top of the unit and optionally available mounting hardware. In the standard version, the unit does not need to be opened for electrical connection. Terminal blocks for the power supply, as well as the connectors for the control unit and parallel operation, are accessible from the outside.

TEKADOOR CAT Electronic Multifunctional Control System

  • A 20-meter pre-assembled, shielded data cable is included as standard with devices equipped with PWW and electric heating.
  • The 5-stage CAT control system includes a manual/automatic mode and a summer/winter switch as standard features.
  • A weekly timer with a timer function can be implemented optionally using enable contacts.
  • For winter operation, a solenoid valve rated up to 2.5 A can be connected (optional).
  • With the CAT control system, the airflow can be manually adjusted in 5 steps, and the heating output—which, in the case of electric heating, depends on the fan speed—can be manually adjusted in 3 steps.
  • An enable contact and potential-free operating and fault signals are available for control via a customer-supplied BMS or DDC.
  • Up to 10 devices can be connected in parallel in a master-slave configuration.
  • On-site control via a ModBus interface is also possible.

Heat exchangers for various heating media:

DHW: for standard-temperature DHW 70/50°C and low-temperature DHW 60/40°C; other temperatures available upon request.
DX: DX coils brazed under nitrogen for use with heat pumps (heating mode only). High-quality heat exchangers made of copper tubing with pressed-on, extra-strong aluminum fins.
ELEKTRO: 3-stage 400V heat exchanger, spiral-shaped and corrosion-resistant, with thermal overheating protection and a run-on circuit.

Self-supporting sheet steel housing with no visible screws. High-quality powder coating in RAL 9016 (traffic white) as standard. Other colors are available. Inspection flap screwed into place behind the intake grille. Aerodynamically optimized aluminum outlet louver (natural anodized) that is adjustable in 5 positions and flush with the bottom of the unit. Intake grille (in the unit’s color) made of perforated sheet metal with a micro-grille behind it serving as an intake filter.

Easy-to-maintain cleaning (micro-grille) without opening the unit—simply vacuum the intake grille. A blind-bolted and secured access panel (hinged on one side) on the underside of the unit is easy to open for maintenance work.

THE Zephyr-Plus EC Series

Discover the various models in the Zephyr-Plus EC Series— designed for maximum performance, modern design, and efficient airflow in a wide range of applications.

ZEPHYR-PLUS M EC
Application Example
Zephyr-Plus EC ZEPHYR-PLUS M EC

Ready-to-connect door air curtain systems in the following variants:
Free-hanging, for visible installation above the door. Recirculating air is drawn in from the front, facing the room.
Cassette, with integrated intake chamber and surrounding frame for flush-ceiling installation. Recirculating air is drawn in from the bottom, facing the room, with a freely accessible access panel.
Installation in a suspended ceiling, with an integrated intake chamber, and sliding intake and exhaust connections for installation in a suspended ceiling (optional). Recirculating air is drawn in from the underside facing the room.
