Zephyr-Plus EC

The Shop Classic

Applications

Zephyr-Plus EC is the classic model for use in shops. Installation ready unit which can be used for many applications, with 4 installation variants. Free-hanging, flush with the ceiling as a cassette, installation in suspended ceilings with sliding supports, and, on request also available as a floor-mounted vertical unit.

The housing

Self-supporting sheet steel. Screws are not visible.
High-quality powder coating, RAL 9016 as standard (traffic white). Other colours are available. Access panel hidden behind the intake grille. Aerodynamically-optimised aluminium discharge fin (naturally anodised), flush with the underside of the unit and adjustable in 5 stages. Perforated metal intake grille (same colour as the unit) with micro grille behind it as an intake filter.

Heating media

Heat exchangers for different heating media
LPHW – for normal temperature LPHW 70/50°C and low-temperature LPHW 60/40°C, other temperatures available on request. DX – DX register soldered under nitrogen for operation with heat pumps. High-quality heat exchanger made from copper tubes, with pressed-on, extra-strong aluminium fins. ELECTRO: Series M and L: 3-stage heat exchanger 400V, spiral form, corrosion resistant, with thermal overheating protection and switch-off delay.

EC fans

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 by a PWM signal (pulse width modulation) – and for the DX with 0-10 V. They do not just comply with Directive ErP, but actually exceed this standard.

Mounting

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.

Maintenance

Easy to clean (micro grille) without opening the unit by simply vacuuming the intake grille. Discreet secured access panel hidden on the lower side of the unit (hinges on one side) – easy to open.

Control

Electronic TEKADOOR GTC EC control unit, multifunctional with touch display, including an optional ModBus interface
A GTC 1 EC control unit is used as standard for models with LPHW heating. A GTC E EC control unit is used for models with electrical heating. The units come with 20 m preassembled and shielded data cable. The GTC 1 EC 5-stage control unit includes the ability to switch from manual to automatic and from summer mode to winter mode
as standard. A solenoid valve of up to 2.5 A can be connected as an option for the winter mode. With the standard GTC E EC control unit, the airflow can be selected manually in 5 stages and the heating capacity – depending on the fan level – can be selected manually in 3 stages. Each 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.

Connections

Heating connections – flow and return – on top of the unit as standard for easy connection to the on-site heating system. Optionally, the connections can also be located at the side.

_0000_tekadoor-luftschleier-zephyr-ec-schnittstelle-datenkabel

Data cable connection/interface

Simple, standard plug and play connection of the data cable and an optional solenoid valve on the top side of the unit. The connection can be offset on request.
Control:
Input for the data cable to the control unit.
Auxiliary:
Output for parallel operation with other units.

_0002_tekadoor-luftschleier-zephyr-ec-anschlussbox

Connection box (LPHW)

Simple electrical connection via connection box (voltage supply 230V/50Hz on the top of the unit); side connections are available as an option.
Exception:
Electrical units with a heating capacity greater than 22,5 kW.

Discharge fin

The shielding performance of the door air curtain system is optimised by adjusting the discharge fin. The fin can be adjusted in 5 stages. During the heating period, the discharge fin should be tilted outwards by 10 to 15 degrees to prevent cold air coming in from the outside. In contrast, during operation in the summer, the fin is tilted inwards, so that the cooled indoor air cannot escape.

Optional accessoires

Thermostatic straightway valve

(Setting range + 20 °C to + 35 °C) limits the discharge temperature (constant supply air temperature limitation). Also available as a 3-way valve.

Door contact solenoid switch

In automatic mode switches on the door air curtain in the preselected stage.

Ceiling attachment set

For problem-free, vibration-free ceiling attachment, consisting of M8 or M10 threaded rods, up to 1000 mm length, vibration dampers, turnbuckles and counter nuts.

Frost protection thermostat

For monitoring LPHW heat exchangers exposed to the risk of frost. As soon as the temperature falls below +7 °C, the fans are switched off and an optional solenoid valve is opened.

Zephyr-Plus EC

Optional accessoires

Solenoid valve

Opens or closes the warm water circuit in the summer/winter setting of the control unit, in order to close the heating water circuit and save energy during summer operation or when the air curtain is not working (normally closed).
Caution: If solenoid valves are used, it is expressly recommended to install a frost protection thermostat (automatically actuated) and a strainer.

Thermo-electric shut-off valve

230 V / 50 Hz, normally closed. On-site installation in the heating flow. Actuated by the summer/winter circuit. Summer function – closed. Winter function – opened.

Electronic control valve

Electronic valve with 0-10V impulse and blow-out temperature sensor completely installed and wired. In combination with the GTC 2 control, a preselected blow-out temperature is kept constant.
