Op­ti­mise your op­er­a­tions with spray tech­nol­ogy

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

Spray tech­nol­ogy can be ap­plied to many dif­fer­ent ap­pli­ca­tions in over 200 in­dus­tries. As the world’s lead­ing ex­pert in spray tech­nol­ogy, Spray­ing Sys­tems Co. has man­aged to grow their prod­uct range to in­clude over 90,000 spray prod­ucts. With sales of­fices all around the world, in­clud­ing in New Zealand, and with over 12 man­u­fac­tur­ing cen­tres, Spray­ing Sys­tems Co. has been able to sup­ply their cus­tomers with spray tech­nol­ogy so­lu­tions for 80 years. Their spray prod­ucts and au­to­mated sys­tems can be found in bak­eries, food and bev­er­age pro­cess­ing plants, abat­toirs, pa­per mills, mine sites and phar­ma­ceu­ti­cal pro­cess­ing plants.

A pop­u­lar and ver­sa­tile prod­uct that can be used for sev­eral ap­pli­ca­tions is the Pul­saJet ® spray noz­zle. For ap­pli­ca­tions that re­quire coat­ing with vis­cous liq­uids, scor­ing bread rolls, glaz­ing pies and pas­tries and spray­ing an­timi­cro­bials onto meat and poul­try prod­ucts, the Pul­saJet spray noz­zle is the ideal choice. The spray noz­zle is ca­pa­ble of achiev­ing cy­cle speeds up to 15,000 per minute to keep up with fast line speeds. Pul­saJet spray noz­zles are of­ten used in con­junc­tion with Pre­ci­sion Spray Con­trol (PSC) sys­tems to achieve ac­cu­rate and uni­form cov­er­age of the prod­uct or tar­get. PSC is at­tained via turn­ing the spray noz­zles on and off very quickly to con­trol flow rate re­sult­ing in flow that ap­pears to be con­stant. Due to the pre­cise ap­pli­ca­tion achieved through the use of PSC, op­er­a­tors can ex­pe­ri­ence sav­ings in coat­ing and an­timi­cro­bial use, de­creased prod­uct scrap rate and re­duced mist­ing and over­spray.

Blow- off and dry­ing ap­pli­ca­tions can be op­ti­mised by us­ing WindJet ® air noz­zles in place of open pipes and drilled pipe op­tions. The drilled pipe op­tions are noisy, dan­ger­ous and use ex­ces­sive amounts of com­pressed air which ul­ti­mately leads to high op­er­at­ing costs. WindJet air noz­zles dra­mat­i­cally re­duce com­pressed air use which can lead to sav­ing thou­sands of dol­lars per year. The noz­zles can re­duce per­ceived noise by up to 60%, de­pend­ing on the ini­tial air pres­sure, mak­ing them a safer op­tion for on­site work­ers. WindJet air noz­zles can be used to dry bev­er­age bot­tles, blow­ing and mov­ing ma­te­ri­als off con­veyor belts, cool­ing cans after weld­ing and ap­pli­ca­tions where a con­tin­u­ous air stream is re­quired.

For spray­ing coat­ings and ad­di­tives, wash­ing con­vey­ors, dust con­trol, VeeJet ® spray noz­zles are ideal. The spray noz­zles can be mounted onto spray head­ers or man­i­folds and are avail­able in high pres­sure and high im­pact ver­sions. Mul­ti­ple spray noz­zles can be used in the same se­quence and still re­sult in even cov­er­age due to the fan shaped, ta­pered spray edge pat­tern de­sign of the VeeJet spray noz­zle.

Flood­Jets ® are a type of spray noz­zle that can be used for fire pro­tec­tion as well as cool­ing con­veyor belts, foam knock­down and rins­ing ap­pli­ca­tions. They pro­duce a wide an­gle, de­flected flat fan spray pat­tern mak­ing the noz­zle ideal for op­er­a­tions re­quir­ing wide cov­er­age. The ori­fice of the noz­zle is pro­tected from dam­age and its de­sign leads to min­imised clog­ging. Flood­Jet spray an­gles range from 73° to 153°.

Spray­ing Sys­tems Co. also sup­ply tank clean­ing spray noz­zles and hand­held spray guns. Their TankJet ® tank clean­ing prod­ucts can be used for tanks as small as 1m in di­am­e­ter and as large as 30m in di­am­e­ter. The tank clean­ers are de­signed to en­sure a thor­ough clean whilst re­duc­ing the amount of wa­ter and chem­i­cals used.

Their line of GunJet ® spray guns are avail­able in high, medium and low­pres­sure op­tions and are suit­able for gen­eral plant and equip­ment clean up. The spray guns pro­vide an ef­fec­tive clean in a short amount of time as the op­er­a­tors are able to tar­get hard to reach ar­eas, such as cor­ners and be­neath con­vey­ors, with ease. Their han­dles fea­ture an er­gonomic de­sign that aids in the op­er­a­tor’s com­fort and re­duces fa­tigue. An ad­di­tional ben­e­fit of us­ing th­ese man­ual, hand-held spray guns is the amount of con­trol the op­er­a­tor has dur­ing clean­ing and wash- down ap­pli­ca­tions which re­duces the chance of spread­ing con­tam­i­nants onto nearby equip­ment.

In ad­di­tion to their vast se­lec­tion of spray prod­ucts, Spray­ing Sys­tems Co. have a spe­cialised team of Au­toJet ® project en­gi­neers who de­sign and man­u­fac­ture au­to­mated spray sys­tems. Their sys­tems are avail­able in sim­ple ‘on and off’ spray noz­zle con­trol va­ri­eties to more ad­vanced sys­tems that fea­ture au­to­matic ad­just­ments and ac­cu­rate mon­i­tor­ing of ex­ter­nal con­di­tions in­clud­ing changes in line speed. The Au­toJet team can also cus­tomise an ex­ist­ing so­lu­tion to suit your ap­pli­ca­tion’s spe­cific needs.
