THE PATENTED* TECHNOLOGIES QPE Quality Performances – Efficiency
- VARIPLENUM®: patented designing technology with COMPENSATED GATHERING PLENUM, which combines together all the AHUs and all the PULSERS® in one single aeraulic circuit. This technology allows to reduce the PULSER®’s diameter, and allows the functioning of the MULTI-FUNCTION PLANTS.
- TWIN™: patent pending technology of multi-functional splitting of the PULSERS®, with the aim of giving each PULSER® different duties, variable between them. Also this technology allows the realization of MULTI-FUNCTION plants. Instead of having just one duct with a big diameter, there are two or more parallel ducts, so that they can have different functions. In this way the primary PULSER® easily recovers, by induction, the variable air flow from the secondary PULSER®.
- PIGRECO: patent pending connection between lines of the “started up flow” kind, for TWIN™ and VARIPLENUM® connections. This connecting system allows to join together two parallel ducts (TWIN™) to a perpendicular duct, with two 45° Y branches opposite to each other, reducing turbulences to a minimum.
- VARIAMIX: calculation technique (know-how SINTRA) of the variable modulating air flow perforations, which allows the variation of the exit air speed from the holes which, depending on the circumstances, can be extended up to 50-100% without significant performance loss.
- VARISTEP®:calculation technique (know-how SINTRA) of the perforations which privileges the “passive influence areas”, allowing the plant’s functioning at a variable air flow by steps, keeping a constant exit air speed from the holes. This technology allows to increase the PULSION efficiency even in the “passive influence areas”, next to the air throw area. Therefore, in a plant constituted by several PULSERS®, equal and parallel between each other, each equipped with its own AHU (or roof-top), it is possible to obtain excellent performances even by intercepting the functioning of two PULSERS® out of three. With regards to the plant’s total air flow, this allows a variable air flow by steps, intercepting the AHUs in an apposite sequence.
- VARIBOOST®: patented technology, finalized to obtain the acceleration of the plant’s set in motion times and the running of a multi-function plant. This technology allows the increase of the “PULSION power” at set time periods, by intercepting the secondary PULSERS® with special dampers, in order to boost the functioning of either the primary PULSERS®, or the dedicated technical ones.
- SPLIT: designing technique (know-how SINTRA) for the TOTAL energy upgrading of the heating plant, which separates the introduction of thermal power from the homogenization plant for the environment’s temperatures. This technology uses autonomous self-sufficient PULSERS®, each of them supplied by a special fan, in order to perfectly blend all the heat sources in the environment, in a totally independent way from the heating plant. As an extremely powerful destratifier, it allows to elevate any existing and obsolete plant to the maximum levels of energy efficiency. This technology also allows to realize new plants with “simple heaters” (hot air generators, unit heaters, heating panels, etc.), also badly distributed in the environment, by homogenizing all temperatures, both vertical and horizontal in the environment, through the autonomous SELF-SUFFICIENT PULSERS® , conveniently conceived for each plant.
- CONICO: patented PULSER® with a conical shape which exploits the calculation of the PULSER®’s final diameter with the aim to privilege the “coaxial PULSION” rather than the “tangential PULSION”. This particular technology allows to increase the “PULSION efficiency” particularly useful in some great volume buildings, where it is necessary to set in controlled motion the big mass of the environment air with a little available air.
- VARIPULSE®: patented motorized PULSER® able to rotate on its own axis, so that the air throw angle is adapted as the air flow and the supply air temperature vary. (Commercialization foreseen for end of 2013).
- VARITRAP®: patented mechanical calibration system for the manual regulation of the residual air speed at floor level. This system allows to calculate a PULSER®’s hole punching pattern in the maximum yield conditions, also risking residual air drafts. In the case of eventual air drafts, during the calibration phase of the plant, it is possible to partially open the VARITRAP® placed at the beginning of the PULSER®, “discharging” in this way part of the supply air in the upper part of the PULSER®. This air is then immediately and totally “retrieved” from the induction in the first meters of hole punching. In this way, the PULSER® ’s nominal air flow is reduced, consequently reducing the air exit speed from the holes and the “PULSION power”.
- VARITOP: air diffusion system (know-how SINTRA) by means of false-ceiling panels with a calibrated hole punching, for laboratories, industrial kitchens and low environments with great air volumes circulating. This system does not foresee the use of PULSERS®, but foresees simple perforated diffusion ducts which partition the great quantity of supply air inside an area delimited by a false ceiling. The air is then diffused in the environment through panels with calibrated holes, positioned on a traditional false-ceiling structure. For each single plant, SINTRA dimensions the different holes to be applied to part of the false-ceiling panels, whereas the remaining part of the panels is left without holes. In this way, the customer will have the possibility to position the non-perforated panels as they like, above the areas they want to protect from air drafts risks, and the panels with a differentiated hole punching will be positioned in the areas where the air drafts are better tolerated.
- HYGROCOOLING®: patented system for the humidification and adiabatic cooling at high efficiency , which utilizes the PULSER® ’s depression area to exploit the “micro-turbulent flow” induction, in order to easily vaporize the atomized water drops. A high pressure pump, equipped with all the necessary control and protection systems, feeds apposite nozzles which are positioned in the upper part of the PULSER® by a network of flexible hoses custom assembled for each plant. This high power humidification system generally has a lower cost compared to the ones introduced inside an AHU, and it has an evaporation capacity up to 20 times higher, profiting from the evaporation skill derived from the endogenous heat and from the quantity of induced air, which is about 30 times higher than the fan’s one. The PULSION also guarantees the perfect repartition of the humidity in the environment. A further advantage is given by the fact that the supply air ducts keep dry internally, avoiding all risks connected to bacterial proliferation.
COMPLEMENTARY PRODUCTS
- VARITOTEM®: patented system of air barriers with non-heated external or environment air for industrial doors , with an adjustable azimuth angle in function of the height of the building’s “neutral area”. The system foresees a group of independent cylindrical modules of 1m of length, simple and powerful, which can be assembles between themselves to constitute two columns of variable height to be placed on the door’s sides. (Commercialization foreseen for end of 2013).
- MODULAIR: summer de-superheating system (know-how SINTRA) for great volume buildings which uses low energy vertical towers from 40.000m3/h and with an installed power of just 1kW. These high performance vertical towers allow to realize a correct ventilation of the industrial buildings, particularly with the presence of endogenous heat, with great air flows (10-20 vol/h) at a very low cost both for the installation and for the running. As a general principle, to be adapted case by case to the single needs, the system consists in concentrating on just one wall, right under the roofing, the entirety of the towers, leaving all the openings to the outside, such as doors and windows, on the opposite wall. In case of insufficient openings, another series of supply air fans is realized, always on the opposite wall to the extraction ones. In this way a great air draft is created in the upper part of the building, able to carry all the heat which tends to stratify under the roofing. Therefore the heat produced in the lower part of the building will tend to rise more easily, in order to be then removed by the air draft itself.
