Tips: Can I install VFD to an extra enclosure?
In some cases it is feasible to apply containerized solutions for VFD systems, the generation of heat loss and transportation/exchange of heat has to verified with the changes in the ambient temperature and humidity of the environment. This is comparable to the marine applications where VFD panels end up in compartments below deck.

In most cases VFDs are installed in a controlled environment as you have to avoid dirt/dust and moisture. Ambient heat is mostly countered by considering it with the dimensioning of the VFD rating.

We installed the VFD input and output filters and other associated hardware in an IP55 sealed walk in skid enclosure. We then added an external industrial air conditioner on one end with stainless steel tubes to cool the internal heat and heat caused by the sun loading and high ambient temperatures.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
