spray booth

Product Description

The spray booth itself is generally the largest energy user, since great volumes of pre-heated fresh air will have to be supplied to make up for contaminated exhaust air. These air volumes cannot be reduced at will, since health and safety standards set down by law have to be observed. A paint spray booth must provide adequate air exchange in order to control the concentration of flammable vapors.

Now SYLVAN help you to reduce air volumes and energy needs

Rotary heat exchanger

Exact equipment planning, taking full account of customer requirements, ensures both low operating costs and high quality standards.

2. Spray booth and drying system

Capitalize on major savings potentials for thermal energy (up to *5% and in some cases *5%)

4. Part conveyance and material feed

Reduce handling effort, eliminate downtimes, boost productivity

3. Improved utilization of the paint, more effective application technology

Reduce paint and compressed air consumption (up to *5%)

Summary of the business and environmental advantages

Direct firing with gas line burners(installed directly in the booths air feed ductwork) can achieve savings of up to about thirty percent. The advantages are short heat-up times, exact temperature regulation (broad regulation range of *0:1), low maintenance effort. Quick heating also makes for shorter drying

periods.

Energy-saving circuitry

This circuitry offers the capability to reduce energy consumption to a minimum during breaks in operations or while setting up parts for finishing. The mechanism is triggered by hanging up the spray gun. Minimizing exhaust air reduces the energy required for heating the make-up air. Such circuitry is available in two versions. The first is an economical pneumatic damper control for smaller systems. The second is electrical control of the motors via the switchgear cabinet; here a frequency inverter is used to

regulate the fresh air supply and exhaust fans.

Moving certain painting tasks off the line

Small parts, for instance, can be painted in booths featuring low air throughput. The SYLVAN line also includes specially-designed bench booths and exhaust walls in a variety of working widths. These guarantee convenience for operators and are suitable for continuous operation at low energy consumption. Check to determine whetherchanges in the materialscould help reduce the effort and energy invested per part for ventilation and drying. Applying fewer layers of paint might be one option. This could also achieve savings in terms of the labor involved and the consumption of paints and solvents.

Good parts handling and effective application techniques

The aim is to reduce the parts dwell time in the booth while achieving maximum process reliability. This not only saves time, but energy, too.

Rotary air-to-air heat exchangers (thermal wheels)are regenerative. This means that the moisture is recovered along with as much as *2% of the thermal energy. The SYLVAN air make-up unit with thermal wheel was developed especially for use in surface finishing technologies. It is a valuable

and innovative contribution to resource conservation. High air volumes, upwards of *5,**0 m3/h, are a prerequisite for using these rotary heat exchangers.

Cross plate heat exchangersare recuperative; moisture is not recovered.The heat passes through thin plates, with recovery levels of up to *8%.The air streams are strictly separated. Whenever solvents are used, the intake and exhaust streams have to be kept absolutely separate. That frequently makes the cross plate heat exchanger the perfect solution. The amortization period is short, often less than two years.

Change filters regularly

This keeps the electric motors from drawing too much
