Trend+ EC

The Store Classic


Trend+ EC
All-Purpose Air Curtain


Trend+ EC is the tried-and-true classic for retail spaces—versatile, powerful, and flexible to integrate. This ready-to-install unit offers numerous application possibilities and, with three installation options, adapts perfectly to different room layouts: free-hanging, flush with the ceiling in combination with an intake chamber and an optional aluminum trim frame, or with a sliding connector for installation in suspended ceilings.

Thanks to service-friendly filters and micro-intake grilles, easy installation, and the powerful Synchrostream discharge system, Trend+ EC is designed for comfortable operation and high functionality. A variety of heating media also allow for a customized design to meet a wide range of requirements.

The Classic Choice 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. Available in a low-noise version
  4. Installation options: Free-hanging, flush with the ceiling with an intake chamber, recessed ceiling installation with a sliding connector, floor-standing unit available upon request
  5. Custom unit lengths up to 3,000 mm
  6. Easy-to-maintain filters or micro-intake grilles
  7. Synchrostream Exhaust System
  8. Various heating media are possible
  9. TEKADOOR Electronic Multifunction Control Unit; on-site control is optional

Heat exchangers for various heating media
DHW: for standard-temperature DHW 70/50°C and 80/60°C; for low-temperature DHW 60/40°C; other temperatures available upon request. High-quality heat exchangers made of copper tubing, with press-fitted, extra-strong aluminum fins.
ELECTRIC: Series 5, 7, LNS, and HE-L: 3-stage, spiral-wound, corrosion-resistant heat exchangers. The electric heat exchangers feature a run-on circuit and overheating protection.

Easy-to-maintain filter cleaning thanks to the unit's simple opening mechanism. The inspection hatch on the underside of the unit—which is blind-bolted and secured (hinged on one side)—is easy to open for maintenance work.

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.

The self-supporting sheet steel housing, which is screw-free in the visible area, is equipped with an easy-to-install mounting bracket and is available in the standard color white (RAL 9016). Custom colors or stainless steel finishes are available. The access panel is screwed into place behind the intake grille. Adjustable, aerodynamically optimized Synchrostream discharge system (natural anodized) that flushes with the bottom of the unit. Intake grille (in RAL 9006) made of perforated sheet metal with a G2 rigid foam filter behind it.

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.

Simple and easy-to-install mounting using recessed rivet nuts (M8) on the top of the unit and mounting hardware available as an accessory. In the standard configuration, 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.
