Equipment covers
made to measure and ventilated

Ventilated made to measure covers for your outdoor units - waterproof in Cover-PVC and built so that no moisture is trapped underneath. They are meant for equipment that is switched off, cooled down or shut down for the season. A heat pump, by contrast, runs all year and gets a partial roof from us, never a full cover.

A fit you can see

Shaped for your outdoor unit

The cover is sewn to the measurements of your unit and sits taut, without flapping. A drawcord and tension in the hem hold it securely, and the ventilated construction lets moisture escape from underneath. That way the fabric does not lie tight against the metal, where condensation would otherwise collect.

Before you cover a unit

Only units that are off, cooled down or shut down
Only cover a unit when it is switched off, completely cooled down and - where applicable - shut down for the season. A running, warm or operating unit is not covered. The instructions of the unit manufacturer in the manual always take precedence.
Heat pumps and air conditioners are special cases
A heat pump runs all year and must never go into a full cover - for that we make our partial roof. A winter cover for an air conditioner is only meant for a unit shut down for the season and has to come off before it is switched on again.
For every outdoor unit

Covers by unit

Outdoor units rarely come in standard sizes - we make every cover individually to your measurements, with no minimum order. What matters with each one is the right condition of use: cover it when the unit is off and cooled down, or shut down for the season. That keeps the weather protection high without obstructing operation.

Our design principle

Why ventilated protects better than sealed

A universal cover that seals completely sounds like more protection - but it is the most common reason for complaints on the market. Under a sealed cover the residual moisture in the surrounding air collects as condensation on the cool metal, and that turns into rust, mould and mildew stains. We do not solve this with a "breathable" fabric but through the construction: the fabric itself stays vapour-tight and therefore genuinely waterproof, while the air moves through deliberately placed openings and an open hem. The weather protection stays high and the moisture still finds its way out.

Concealed vents

At least two vents under flaps and fabric folds let air circulate without letting rain in.

📐

Ventilated hem

Instead of a sealed bottom edge, a defined ground clearance of at least 5 cm - damp air escapes downwards and no heat builds up.

🧵

Made to measure tension

The cover sits taut on your unit, does not flap and does not lie tight against the metal, where condensation would collect.

So the cover fits

How to measure correctly

With outdoor units the fit and the cut-outs are what count - a few measurements get it right, and if in doubt we check them together before production.

Measure width, depth and height

Measure at the widest and highest point - including connections, cables and the base.

Mind the air paths

On units with intake or discharge openings we plan cut-outs or a loose fit, so nothing is constrained.

Choose the fastening

The standard is tension straps with click buckles plus a drawcord in the hem - storm-proof at the corner points, instead of elastic that goes slack or single eyelets that tear out.

Frequently asked questions

Frequently Asked Questions

No. A cover belongs only on a unit that is switched off, completely cooled down and - where applicable - shut down for the season. A running unit needs clear air paths, gives off heat or exhaust and would overheat or trap moisture under a cover. So only cover it once operation has ended and the unit is cold, and follow the manual of the unit manufacturer, which always takes precedence.

A heat pump runs all year, draws air in and pushes it back out, and its condensate has to drain freely at the bottom. A closed cover would block the air paths and the drain - which manufacturers rule out in their installation specifications. The only sensible protection is from above, against snow, hail and leaves, with the sides and air paths left completely clear. That is exactly what our partial roof for heat pumps does, linked further up this page.

No, and that is deliberate. Cover-PVC is vapour-tight and therefore genuinely waterproof - a breathable fabric would let water through in prolonged rain. The air circulation here does not come from the weave but from the construction: at least two concealed vents and a defined ground clearance make sure moisture escapes and no condensation forms.

A winter cover is only meant for an air conditioner shut down for the season that is neither heating nor cooling in winter. The cover has to be ventilated by design and must be removed completely before the unit is switched on again. Please note: depending on the manufacturer a cover can put the warranty at risk - check the manual of your unit beforehand. If in doubt, we are happy to advise.

What matters is the combination of waterproofing and ventilation. We sew from Cover-PVC, a vapour-tight, PVC-coated polyester fabric with a 4,000 mm water column. To stop condensation forming underneath, ventilation comes from the construction: at least two concealed vents and a ground clearance of at least 5 cm. The fabric is also UV-stable, lightfast (grade 7-8), abrasion-resistant (60,000 Martindale cycles) and tested to OEKO-TEX Standard 100 - for year-round weather protection.

Measure width, depth and height at the widest and highest point - including connections, cables and the base. On request we check your measurements together before production, so the cover fits and the air paths stay clear.

Unsure about size or fabric?

Order a fabric sample or ask for advice - we check your measurements, clarify the right condition of use for your unit and find the right fabric for your made to measure equipment cover together.
