Opening Types
Common openings include screened vents (mesh-backed), zippered access flaps, split corners for electrical boxes, grommeted drain points, and full perimeter drop skirts for units mounted on curbs.
- Screened vents: reduce condensation while blocking debris
- Zippered panels: service access without removing the entire cover
- Grommets: drainage and tie-down anchor points
- Split corner: clears exterior disconnect boxes on commercial side-draft units
Side Draft Openings
Wall-mounted side-draft coolers often need low-side clearance for water lines and high-side relief for warm air paths. Mark pipe exits on your dimension sheet; we position openings away from prevailing wind when possible.
- Keep water line cutouts above typical splash height
- Reinforce edges with binding tape on high-wear openings
- Match opening to pad frame — not only to outer cabinet line
- Browse side-draft cooler covers for standard configurations
Down Draft Openings
Rooftop down-draft units may need top ventilation or skirt clearance around the curb. Specify if the cover must clear a crane lift lid or maintenance hatch. Drainage openings prevent water weight from collapsing lightweight tops.
- Top panel: reflective or reinforced depending on sun load
- Curb-mounted units: measure curb OD separately from cabinet OD
- Wind exposure: fewer large openings on prevailing-wind side
- See down-draft product category for rooftop-ready features
Custom Configurations
Send a sketch or annotated photos for unusual layouts — dual ducts, offset motors, or combined cooler + heat exchanger cabinets. We engineer one-off patterns and can replicate approved designs on future reorders by pattern ID.
- Pattern ID stored for repeat commercial orders
- Multiple openings per face allowed with reinforced seams
- Velcro, zipper, or laced closure per opening — specify access frequency
- Request a quote with photos for complex layouts
