The VivesCo X series operates based on the crossflow induction principle developed by Inteco. The ventilation plenum, where primary air is connected, is located at the top of the casing. An induction zone has been realised below this, with the lower panel featuring a water-transporting heat exchanger. The aerodynamic nozzles under the ventilation plenum blow primary ventilation air into the induction zone, without the air streams touching each other. This flow can realise strong induction because the air flow covers a relatively long distance in the unit, and because air speeds contrast with each other. This means more secondary air can be attracted across the heat exchanger (high induction rate). Mixed air (primary and secondary) is then blown into the relevant space via the outflow opening at the bottom of the unit. The outflow opening has been placed so out-flowing air passes along the ceiling and, due to the coanda effect, continues to travel along the ceiling over a long distance to create the desired cooling or heating.
2 rows of aerodynamic discharge nozzles are used to blow primary (fresh) air into the unit's induction zone. These nozzles are inter-changeable, which means units can be easily modified to suit the new situation if there is a change in the function of the relevant space. The units can be adjusted to suit any situation because nozzles are available in various sizes. The bottom panel of the unit can be opened, which means the insides of the unit, including the heat exchanger, can be reached and cleaned easily.
This flexible induction unit can be integrated into all ceiling systems, or be installed separately on a structural construction.
The bottom panel features a perforated plate.
The specially designed discharge nozzles have an aerodynamic design to ensure low air-related pressure loss. These nozzles also ensure that the VivesCo unit has relatively low noise capacity. The Nozzles are available in three different sizes: S, M and L. This means air discharge speed, noise capacity in the unit and pitch can be determined individually and the best possible configuration can be found for each situation.
The unit can be integrated into various ceiling systems. This modern, streamlined unit is available in various lengths, RAL colours and shine finishes. It is also possible to fit the unit with specially designed bulkheads for non-standard ceiling systems. Discuss the possibilities with one of our advisors.
The X-300 unit has a modular width of 300 mm and the X-600 unit has a modular width of 600 mm. Both versions are available in several lengths.
Water connections feature a smooth copper end with a diameter of 10 mm. To ensure accurate connection, the connections of 4-pipe units are coded with CH and CW.
The units can also be supplied with optional connection sets in the form of flexible oxygen diffusion resistant connection hoses. The hoses can be fitted with various connection devices.
Air-related connection X-300
The standard diameter of the air connection is 100 mm. In case of side connection, the connection spout will already be mounted to the unit casing. In case of top connection, the connection spout will be supplied separately along with a cap for the opening. This can be easily installed using the accompanying screws. An optional 125 mm air connection is available in case of top connection.
Mounting in a T girder ceiling
The VivesCo ceiling induction unit can be placed in a T girder support construction. However, the unit must be mounted on a separate deck. That is why the units feature two mounting holes on both sides.
Mounting in a C grid ceiling
The VivesCo ceiling induction unit can be placed on the C grid using the accompanying mounting brackets. The C grid must be mounted to the structural ceiling in a responsible manner, so it is able to support the unit. We also recommend mounting the unit separately to the structural deck. That is why the units feature two mounting holes on both sides.
If the VivesCo ceiling induction units are not mounted in a ceiling-based support construction, then they can be mounted on the structural deck. That is why the units feature two mounting holes on both sides. If units are mounted freely in the relevant area, an optional wider bottom panel can be fitted in order to realise the desired blowing pattern.
Use and maintenance
The unit's bottom panel is easy to open if cleaning activities need to be carried out. A vacuum cleaner can be used to remove dust from the bottom of the extraction grid, and the surface can then be wiped with a moist cloth. Dust can also be removed from the inside of the heat exchanger. This must be done by opening the bottom panel. Additional activities must be carried out using a Ph neutral cleaning product. For the rest, VivesCo ceiling induction units are maintenance free.
