CoolerFit — Custom Evaporative Cooler Covers

Swamp Cooler Cover by Brand and Model

Find cover dimensions for Portacool, Hessaire, MasterCool, and Champion evaporative coolers in inches and centimeters, then confirm the installed unit before requesting a custom quote.

How to Read the Size Chart

Use the cooler's actual outside cabinet dimensions, not pad size or nominal model capacity. All dimensions below follow height × width × depth. The suggested cover dimensions include a starting fit allowance, but cabinet revisions, casters, handles, ducts, fabric, and opening layouts can change the final pattern. Measure the installed unit before ordering and send the actual dimensions without adding your own allowance.

  • The hem cinches at the base; added height provides fitting ease rather than a loose skirt
  • We confirm extra clearance around casters, handles, control panels, ducts, and side openings
  • A flexible project MOQ is confirmed from size, material, features, quantity, packing, and destination

Portacool APEX Cover Sizes

APEX model numbers identify the series, not the cabinet size or airflow. These portable units commonly need caster, handle, or hose clearance; tell us whether the cover should stop above the wheels or extend toward the floor.

Hessaire Portable Cover Sizes

Hessaire listings may present length, width, and depth in different orders. The table normalizes them to height × width × depth. Confirm the orientation and measure the unit because some retailers publish different depths for the same series.

  • For MC26A, confirm which published dimension is the height
  • Some MC37 retailers list 17 in depth; if yours measures 17 in, the starting cover depth becomes 18.6 in / 47.2 cm

MasterCool Portable and Window Sizes

For a window-mounted MCP44 or MCP59, measure only the outdoor portion if that is the section being covered. Do not automatically use the full product depth.

ADA is down-draft, ASA is side-draft, and AUA is up-draft. Tell us the airflow direction so duct and service openings are placed on the correct face.

Champion Residential and Commercial Sizes

DD models are down-draft and SD models are side-draft. Large commercial cabinets require correct airflow orientation, reinforced fastening, and a site check for ducts, disconnect boxes, or roof curbs.

Why Large Covers Need More Ease

A cover for a two-meter cabinet is heavier and harder to lift than one for a small portable unit. Manufacturing tolerance, seam movement, handles, casters, and service panels also add up across a large pattern. Extra ease helps installation, but exposed covers still need straps or buckles so wind cannot work under the hem.

  • A zipper side opening is quick and can use a storm flap for outdoor exposure
  • Hook-and-loop provides frequent access but must be kept clean in dusty sites
  • Lace-up grommets provide adjustable closure for wind and dust
  • Very large or irregular patterns are confirmed before cutting

Configure the Cover Around Your Unit

Choose polyester, Oxford, canvas, or vinyl-coated fabric for the climate; add openings for casters, handles, ducts, water inlets, or power cords; and select a drawstring, straps, buckles, or lace-up grommets. Logo and color options are also available. Typical production is 10–14 business days after dimensions, construction, quantity, and artwork are approved; shipping time is separate.

Compatibility and Dimension Notice

Brand names and model numbers are used only to identify compatible units. CoolerFit is an independent custom-cover manufacturer and is not affiliated with or endorsed by MasterCool, Hessaire, Champion, or Portacool. Unit dimensions are based on published specifications available in 2026 and may change; the measured installed cabinet and approved quote control the final pattern.

FAQ

Can I submit measurements in centimeters?

Yes. Send centimeters, millimeters, or inches and use one measurement system consistently across the quote.

Can you make a cover for a model that is not listed?

Yes, subject to the confirmed project MOQ. Send outside height, width, and depth, quantity, photos, destination, and notes about protrusions or openings.

Should I add extra size to my measurements?

No. Send the actual maximum outside cabinet dimensions. We add the controlled fit allowance when the pattern is prepared.

Do portable cooler heights include casters?

Published heights often include wheels, but listings vary. Measure the installed unit and state whether the cover should stop above the casters or extend toward the floor.
