The disclosure encompasses systems and methods for performing high temperature and high humidity curing of tablets using air flow delivered from a recirculating air handler to a pan coater of a tablet coating device. The recirculating air handler may be integrated into a preexisting tablet coating device so that the air flow may be delivered by the preexisting air handler or by the recirculating air handler as desired.

A transportable body (10) suitable for spraying vehicles comprising a main body having a spray compartment (12) with a floor, a ceiling, opposed side walls (16, 18), and a vehicle entry door (20) an upper air inlet plenum for introducing air through the ceiling and an air exhaust in the floor wherein the air inlet and air exhaust are configured to provide a downdraft ventilation system the opposed side walls of the spray compartment are outwardly moveable from a transport position in which the main body can be loaded onto a transporter and a spray position a utility compartment (14) housing an air inlet handling unit (24) with an air inlet fan for supplying air to the air inlet and an air exhaust handling unit (26) with an air exhaust fan for drawing exhaust air from the air exhaust in the floor, the compartments being arranged end to end and a wall separating the compartments.

The present invention is directed toward a movable airborne contaminant control system having a retractable/extendable booth attached in a sealing manner to a ventilation unit, preferably mounted on wheels. The ventilation unit includes a filter assembly that opens into the work are formed by the booth. Front doors support air filters. In operation, the ventilation unit draws air in a longitudinal laminar flow over one or more work pieces. The filter assembly captures both particulates and VOCs to allow the exhaust air to include an extremely low contaminant load.

The present disclosure is directed to a process for applying a waterborne coating composition in a spray booth and a system thereof. The disclosure is particularly directed to a process for introducing water into incoming air for the spray booth to produce a conditioned spray booth having appropriate humidity levels. The process of this disclosure is particularly useful for applying a waterborne coating composition having effect pigments in a low humidity and high temperature climate.

Disclosed is a portable jobsite spray booth for painting, drying, finishing, routing, sanding, sawing, and processing an object and protecting the processed object. The portable jobsite spray booth includes a plurality of bases, a plurality of first connectors, a plurality of second connectors, a plurality of vertical poles, and a plurality of horizontal poles. A disposable plastic liner is used for covering five sides of the portable jobsite spray booth with one side open. The disposable 5-sided clear plastic liner provides overspray and particulate protection to and from the ceiling, floor, and three sides. The portable jobsite spray booth is provided with a ventilation attachment that accommodates air filter, ducting and blower system.

A transportable vehicle enclosure (1) for painting vehicles includes side, front (6), rear (5), ceiling (4) and floor (3) portions, one of the portions being configured to allow vehicular access; whereby, in use, a vehicle (2) may be placed within the enclosure; the enclosure further including an air handling unit (18) for respectively producing a first temperature level within the enclosure suitable for a spray mode of operation and a second temperature level within the enclosure suitable for a baking mode of operation.

There is provided an energy recovery device for recovering energy from exhaust air which flows through a discharge line. The energy recovery device includes a heat exchanger device having at least a first heat exchanger unit and a heat pump, wherein the heat pump is connected at the high-temperature side thereof to the first heat exchanger unit and is arranged at the low-temperature side thereof in the exhaust air flow in the exhaust air flow direction downstream of the first heat exchanger unit or is connected at the low-temperature side thereof to a second heat exchanger unit which is connected downstream of the first heat exchanger unit in the exhaust air flow direction.

Presented are the method of paint booth air feeding to paint with liquid paints (variants) and an air supply unit to realize the method (variants). Said group of innovations consists of two innovations to the method and three innovations to the installation to realize the methods. In the method (variant 1), a closed air stream is created inside the painting booth and air supply unit, after passing the painting zone it is divided into two streams, the first stream returning to the painting booth, while the second stream, containing flammable liquid vapors, is extracted to atmosphere. Simultaneously, some additional air is taken from atmosphere, mixed with return air and supplied to the paint booth painting zone. In the method (variant 2) a closed air stream is created inside the painting booth and air supply unit, and, after passing through the painting zone, is mixed with some additional fresh air and then divided into two streams, the first returning to the painting booth, while the second stream containing flammable liquid vapors, is extracted to atmosphere. The painting booth with separated units of the air supply unit (variants 1 and 2) is intended to realize the method according to claim 1 (FIGS. 1 and 4). The painting booth with connected units of the air supply unit (variants 1 and 2) is intended to realize the method according to claim 1 (FIGS. 2 and 3). The paint booth with air supply unit (variant 3) is intended to realize the method according to claim 2 (FIG. 5). A better performance and improved ecological properties are the immediate technical results of the innovations proposed.

In order to provide a method for fault analysis in an industrial-method plant, for example a painting plant, by means of which fault situations are analysable simply and reliably, it is proposed according to the invention that the method should comprise the following: in particular automatic recognition of a fault situation in the industrial-method plant (101); storage of a fault situation data set for the respective recognised fault situation, in a fault database (136); automatic determination of a cause of the fault for the fault situation and/or automatic determination of process values that are relevant to the fault situation, on the basis of the fault data set of a respective recognised fault situation.
