KORAFLEX Energy FVE

KORAFLEX Energy FVE is based on the Optimal-V range, extended by 200mm and fitted with regulation for 230 V AC connection. Energy 230 V AC trench heaters are suitable for dry environments and are solely for heating. They are characterized by silent operation and can be connected to BMS (Building Management System).

ECONOMIC version – black lacquered galvanized steel casing, non-lacquered heat exchanger
EXCLUSIVE version – black lacquered galvanized steel casing, RAL 9005 black lacquered heat exchanger

Cover grilles
	Cross grille - design solutions - Cross grilles must be ordered with trench heaters, as casing must undergo alteration. These trench heaters will be fitted with Cross frame suitable for Cross grille. Where a linear grille is required, technical consultation is necessary, as the casing may need to undergo alteration. Linear grilles must be ordered together with trench heaters.

Heat output [W] where t1/t2/ti / EN 16430. Measurements shown in mm including U-frame.

FV TRENCH HEATER INSTALLATION

Construction recommendations

To ensure correct operation, it is essential that the following principles are respected.

Trench heaters must be installed horizontally with the heat exchanger on the window side. For the grille to function correctly, the upper edge of the casing must be straight and level (not buckled or bent).
The maximum recommended distance of the trench heater from the wall/window is 100 mm.
The size of the trough in the floor for thrench heater installation should be at least 100 mm bigger (both in length and width) than the convector.
We recommend connecting the trench heater to the heating system using a lockshield and thermostatic valve. The heat exchanger connection is by an inner G½ thread. Following connection to the heating system, bleed and carry out a pressure test.
When concreting, the trench heater must be levelled using the set screws provided and fastened to the floor using the anchors provided. The anchors keep the trench heater in place while pouring concrete.
While pouring concrete, the trench heater may be weighed down.
Using anchors will extend the bottom width of the trench heater by 42 mm from each side.
While pouring concrete, the trench heater may be weighed down.
While pouring concrete it is important to brace the trench heater to prevent longitudinal buckling. Trench heaters are fitted with spacers for this purpose. Following concreting, these spacers are easily removed.
While pouring concrete or anhydrite it is essential to seal all connection openings to prevent leakage. We also recommend insulating trench heaters against damp.
Where trench heaters are not concreted in, a raised floor support it is recommended to use. Standard models are not self-supporting.
We recommend insulating the outer side of the trench heater casing along the length of the heat exchanger with polystyrene to prevent heat loss into the floor.
For trench heaters with forced convection we recommend undertaking fastening and acoustic insulation by pouring thin concrete along the sides and under the base of the heater.
To avoid contaminating the trench heater, we recommend maintaining the protective hardboard cover in place during construction work. The cover, which is included in the standard contents, is not suitable for walking on and serves solely to protect the trench heater from contamination during installation. Strengthened OSB covers for installation purposes are available as optional extras.
Fans are attached to the trench heater casing using magnets. For stainless steel models velcro is used. This system enables removal of the fans from the trench heater during installation to avoid damage or contamination, etc. Fans may also be removed this way for cleaning when the unit is switched off. With the exception of the Pool series, fans are installed to direct air towards the windows.
Electrical installation design must be carried out by suitably qualified persons in accordance with the relevant regulations.
Installation and servicing of the electrical installation must be carried out by persons with the relevant electro technical qualifications.
Prior to commissioning, the electrical components must be thoroughly inspected in accordance with relevant regulations.

KORAFLEX Energy FVE trench heaters are powered with 230 V alternating current mains electricity. Therefore the electric branch must be equipped with a residual current device with a tripping current of 30 mA. These trench heaters are to be used solely in dry environments, and only for heating.

RAISED FLOOR INSTALLATIONS KORAFLEX FV

Raised floor installations

Structural supports for raised floor trench heater installations offer stable and effective solutions. Structural supports are manufactured from non-lacquered steel and are suitable for raised floors of a depth up to 500mm. Structural supports are suitable for Optimal-V, ENERGY, Variant F2V and F4V. For structural reasons, the KORAFLEX Pool-V model is not recommended for installation into raised floors.

SZP-03 low raised floor support

Trench heaters are fitted with reinforcing bars and set screws, which enable the trench heater to be installed at the required height. Set screws must be anchored to the floor to prevent movement. Reinforcing bars are not included as standard and cannot be fitted subsequently. The screws allow setting a maximum height which is max. 30 mm higher than the trench heater itself. Recommended for raised floors with a maximum depth 30 mm greater than the unit height of the trench heater.

SZP-10 higher raised floor support

Customized solutions for all projects dealing with raised flooring. This is a more robust model of the low raised floor support, equipped with one support at the base of the trench heater. The precise technical design depends on customer's requirements. Recommended for raised floors with a maximum depth 100 mm greater than the unit height of the trench heater.

SZP-30 high raised floor support

Customized solutions for projects dealing with high raised flooring. This is a more robust model of the higher raised floor support, equipped with two supports at the base of the trench heater. The precise technical design depends on customer's requirements. Recommended for raised floors with a maximum depth 300 mm greater than the unit height of the trench heater.

TRENCH HEATER MULTIPLE INSTALLATIONS

Casing types according to water connections and lowered faces for multiple installations

Lowered trench heater casing faces are used where invisible connections are desired between convectors (multiple convectors around a room, eg. in administrative buildings, restaurants, hotels, etc.). When ordering grilles, care must be taken to include information in the order code that the grilles required are to be used with trench heaters with lowered faces. Individual KORAFLEX Pool FKP trench heater casings cannot be combined in this way, and are available in P0 models only.
