I pisinisi fa'aonaponei ma pisinisi fa'aonaponei, e taua tele le sao o tagata fa'afefe vevela i le fa'aleleia atili o le malosi ma le fa'amalieina o faiga. Welded plate heat exchangers ma gasketed plate heat exchangers e lua ituaiga taatele, e iloga uma i latou filosofia mamanu tulaga ese ma foliga faʻavae, faʻafeiloaʻi i faʻaoga eseese ma manaʻoga.

Uila fa'anofo fa'avelae maualuga le fa'aaloalogia ona o lo latou gafatia lelei o le vevela ma le malosi o le tete'e atu i le maualuga o le vevela ma le mamafa. E masani lava ona faia mai le u'amea u'amea po'o isi mea fa'afefete, o latou ipu e fa'apipi'i fa'atasi, fa'amautinoa le fa'agaioiga mautu i lalo o tulaga ogaoga. O nei fesuiaiga e fetaui lelei mo vailaʻau, malosi, gataifale, ma isi pisinisi mamafa, e sili atu i le taulimaina o le vevela maualuga, maualuga o le mamafa, poʻo le sua oona. Ae ui i lea, o le tausiga o mea faʻafefe vevela e mafai ona faʻalavelave, e masani ona manaʻomia le lagolago faʻapitoa faʻapitoa mo le toe faʻaleleia poʻo le faʻamamaina.

I le isi itu, e sili ona lelei le fa'afesuia'i o mea'ai fa'avela mo le fa'alelei ma le faigofie o le tausiga. E aofia ai le tele o papatusi ua faʻamaufaʻailogaina i gaskets, e mafai ona faigofie ona faʻapipiʻi pe faʻasese pe a manaʻomia. O lenei mamanu e le gata e faafaigofie ai le faamamaina masani ma le tausiga ae mafai ai foi mo fetuunaiga gafatia e faavae i luga o manaoga moni. Gasketed plate heat exchangers o loʻo faʻaaogaina tele i le gaosiga o meaʻai, vailaʻau, HVAC, ma alamanuia mama, e tuʻuina atu ai fofo faʻafefe vevela lelei ma taugofie mo tulaga tau faʻagaioiga.

O le fa'atauga fa'apea, fa'ameamea fa'afesuia'i ipu vevela e masani lava ona ofoina atu se fa'amanuiaga i ulua'i fa'afaigaluegaina ma tau fa'agaioiga, talafeagai mo fa'aaliga e utiuti le paketi ae mana'omia le tausiga faifaipea. I se fa'afeagai, a'o fa'auluuluina fa'afesuia'i vevela e ono maualuga atu tau i luma, o lo latou tumau ma fetuutuuna'i i si'osi'omaga faigata e avea ai i latou ma tupe fa'aalu umi.

I se aotelega,ueloina ma gasketed ipu vevela exchangerse tofu lava ma o latou tulaga lelei ma tulaga fa'aoga. O le malamalama i o latou uiga iloga e mafai ona fesoasoani i pisinisi ma inisinia e faia filifiliga talafeagai e faʻavae i luga o manaoga faʻapitoa faʻapisinisi ma tulaga faʻagaioiga, e le gata ina faʻamautinoa le lelei o le faʻagasologa ae faʻapea foʻi le faʻateleina o le tau.
