CLARIO Defogger Rectangular 45 x 30cm | Mirror Demister Pad 34W 12V IP44

Overview

The CLARIO Rectangular Defogger 45 x 30cm is a self-adhesive mirror demister pad designed to keep bathroom and washroom mirrors permanently clear of condensation. Operating on 12V DC at 34W, the pad bonds directly to the rear surface of the mirror and raises the glass temperature marginally above the surrounding dew point, preventing fog from forming rather than clearing it after the fact. Its 450 x 300mm footprint suits medium-to-large rectangular bathroom and vanity mirrors. Sealed to IP44, the pad is rated for general bathroom humidity but should be kept clear of direct water spray.

Key Features

• 450 x 300mm rectangular self-adhesive mirror demister pad
• 12V DC low-voltage operation — safe for wet-zone installation
• 34W heating element, approximately 2.83A current draw
• IP44 rated against dust ingress and light splashing
• Uniform heat distribution across the full pad area — no hot spots or visible banding
• Ultra-thin construction adds negligible depth behind the mirror
• Factory-applied high-tack adhesive backing for direct bonding to glass
• Pre-wired with lead-out cable for straightforward connection
• Silent operation with no moving parts and no maintenance requirement
• Compatible with CLARIO touch-key controls and 12V DC drivers

Technical Notes

• The pad is a resistive heating element and contains no electronics; it requires a regulated 12V DC supply.
• Rated 34W — size the driver with at least 20% headroom above this figure.
• Performance depends on adhesion quality: air gaps between pad and glass reduce thermal transfer and create uneven clearing.
• Typical time to full clarity is 3–5 minutes from cold, depending on ambient temperature and mirror thickness.
• The pad prevents condensation within its own footprint only; the demisted zone matches the pad dimensions, not the full mirror.
• Can be wired in parallel with mirror LED lighting so both activate from a single switch.
• Not suitable for trimming or cutting — the resistive circuit will be destroyed.
• Suitable for use behind standard silvered float glass mirrors from 4mm thickness upward.
• IP44 rating is lower than the round and other rectangular variants — avoid direct spray or submersion.

Wiring & Installation Notes

• Clean the rear mirror surface thoroughly with isopropyl alcohol and allow to dry fully before application.
• Position the pad centrally within the intended viewing zone, peel the release liner and apply firm even pressure from the centre outward to expel trapped air.
• Maintain a minimum 20mm clearance from the mirror edge and from any bevel or cut-out.
• Connect the lead-out cable to a regulated 12V DC supply, observing correct polarity.
• Route the cable clear of the pad body to avoid localised heat build-up against the insulation.
• All 220–240V primary side wiring must be carried out by a qualified electrician and protected by an appropriate RCD.
• Do not energise the pad before it is bonded to glass — operating in free air will cause overheating.
• Allow the adhesive 24 hours to cure fully before first use.
• Installation must comply with local electrical regulations for bathroom zones.

Applications

• Residential bathroom and en-suite rectangular vanity mirrors
• Guest cloakrooms and powder rooms
• Hotel bathrooms and hospitality washrooms
• Spa, sauna lobby and wellness facility mirrors
• Backlit and LED mirror assemblies requiring integrated demisting
