Pain Points We Solve
Staff leaving freezer doors open during every forklift trip
A standard strip curtain stays open for 8–12 seconds after a pallet truck passes because the hooked strips take time to drop back to vertical. Over a 10-hour shift with 60 forklift passes, that adds up to 12 minutes of fully-open freezer door — enough for a 3–5 °C temperature excursion that FSSAI auditors will flag.
Hands-full staff tearing strip curtains open with trolleys
Commissary and hospital kitchen staff carrying full trays push standard strip curtains open with the tray edge, yanking strips off their hooks within weeks. Magnetic PVC panels swing open on a hinged top rail and auto-close behind the trolley — zero hand contact, zero strip damage, zero cross-contamination.
Pharma cleanroom corridors needing a positive-pressure seal
Pharma grade D to grade C transitions need a door that seals tight between passes to maintain the pressure differential. A hooked strip curtain never fully closes; a magnetic PVC door snaps panels together along the neodymium seam and holds 15–25 Pa differential between the two atmospheres.
Blast-freezer curtains freezing fused after 2 weeks
Standard ribbed strip curtains in a -30 °C blast freezer freeze together at the overlap, eventually needing a crowbar to separate. Magnetic PVC doors swing on a hinged rail with a 15 mm inter-panel air gap — no static overlap contact, so the door keeps working at -30 °C indefinitely.
How AERSTER Solves It
A magnetic PVC strip door — sometimes called a self-closing PVC door, hands-free freezer door or snap-close curtain — is a two-panel PVC barrier hinged from a top rail with embedded neodymium magnets along the vertical centre seam. The panels swing out of the way when a forklift or trolley pushes through and snap shut behind, sealing the opening in under 2 seconds with no human contact and no curtain damage. It is the barrier of choice for forklift-traffic cold rooms, hands-full kitchens, pharma pressure-differential corridors and any door where a standard strip curtain leaves residual gap.
AERSTER ships two SLIDE variants from Chandigarh. SLIDE STD uses 5 mm PVC panels with a 12-magnet seam, rated for 0 °C to +50 °C use — the fit for commissary kitchens, pharma cleanroom corridors and supermarket back-of-house freezer lobbies. SLIDE HVY uses 8 mm cold-store grade panels with an 18-magnet seam and low-temperature plasticiser, rated to -30 °C for blast-freezer and ice-cream hardening-room entrances. Both variants swing on a hinged anodised-aluminium top rail with dual-ball-bearing pivots tested to 100,000 cycles (roughly 10 years of commercial-kitchen duty).
Every SLIDE door is built from IS 2508 food-grade PVC, FSSAI-compliant for food-contact zones, and ships with a material test report (MTR) for pharma QA files. The neodymium seam magnets are encapsulated in a food-safe EPDM gasket that stays flexible to -40 °C. Standard sizes are 900 / 1,200 / 1,500 mm wide at 2,000 / 2,200 mm tall; custom sizes cut in-house on 5 working days lead. 3-year comprehensive warranty covers panels, magnets and rail hardware. HSN 3920 — 18 % GST, full ITC for registered buyers.

How to Choose the Right Magnetic
A magnetic PVC door costs 2–3× a hooked strip curtain but only pays back on the right door. Use these five checks to confirm the self-closing premium is justified for your opening — and to avoid the two classic specification mistakes (wrong temperature grade, under-sized swing clearance).
1. Is your door actually a hands-free problem?
Magnetic doors justify their price on forklift-traffic cold rooms, hands-full commissary doors, pharma pressure-differential corridors and blast-freezer entrances. For pedestrian-only doors and low-traffic dry stores, a standard strip curtain is 60 % cheaper and works fine. The test: does the opening need to close behind someone carrying a load without them touching it? If yes, SLIDE. If no, FLEX or POLAR.
2. Pick STD vs HVY by temperature, not by size
SLIDE STD (5 mm panels, 0 °C to +50 °C) fits kitchens, corridors and supermarket back-of-house. SLIDE HVY (8 mm cold-store panels, -30 °C) is mandatory for blast freezers and ice-cream hardening rooms — the low-temperature plasticiser stays flexible where STD panels would shatter. Wrong grade in a freezer is the single most common field failure on magnetic doors.
3. Swing clearance — the 300 mm rule
Panels swing 110° outward either side; leave at least 300 mm clear on both sides of the door frame for the full swing arc. Walls, racks or parked pallets inside the 300 mm zone will jam the panels and bend the pivot pin. Check the drawing before install — most site failures trace back to a too-close rack installed after the door.
4. Seam-magnet count vs door width
900 mm wide doors use 12 magnets (SLIDE STD) or 14 magnets (SLIDE HVY). 1,200 mm doors step up to 16 / 18. 1,500 mm doors use 20 / 24. Undersizing the magnet count on a wide door causes the seam to separate under wind-gust or pressure-differential load. AERSTER auto-specs this from the door dimensions on your quote request — do not over-ride the recommendation to save on cost.
5. Mounting rail, sill & pivot maintenance
The anodised-aluminium top rail surface-mounts with the supplied bracket; recessed mounting needs a 160 mm ceiling void. Pivots are dual-ball-bearing and rated 100,000 cycles — roughly 10 years of 30-cycle-per-hour commercial-kitchen duty. Lubricate annually with food-grade PTFE spray (ships with every SLIDE order). AMC plans include this visit.

Frequently Asked Questions
What is a magnetic PVC strip door and how is it different?+
A magnetic PVC strip door is a two-panel barrier hinged from a top rail with embedded neodymium magnets on the vertical centre seam. It swings open when pushed and snaps shut in under 2 seconds with no human contact — unlike a hooked strip curtain that takes 8–12 seconds to fall back to vertical after a forklift pass. It is the hands-free option for cold rooms, pharma corridors and commissary kitchens.
How much does a magnetic PVC door cost in India?+
AERSTER SLIDE STD starts at ₹18,500 for a 900 × 2,000 mm door (commissary / pharma corridor fit). SLIDE HVY cold-storage grade at 1,200 × 2,200 mm is ₹28,500. Custom sizes are quoted on door dimensions. All prices exclude 18 % GST; ITC available for GST-registered buyers.
Magnetic PVC door vs hooked strip curtain — which should I buy?+
Magnetic SLIDE for forklift-traffic cold rooms, hands-full commissary doors, pharma pressure-differential corridors and blast freezers where strips fuse. Hooked FLEX/POLAR for pedestrian doorways, dry-storage warehouses and low-traffic openings where self-closing isn't worth 2-3× the price. When in doubt: if the user is carrying something, SLIDE pays back.
Can magnetic PVC doors work in a -30 °C blast freezer?+
Only the SLIDE HVY variant. Standard SLIDE STD panels go brittle below -5 °C. SLIDE HVY uses a cold-store-grade plasticiser rated to -30 °C continuous, with magnets encapsulated in EPDM gasket that stays flexible at -40 °C. Wrong grade in a blast freezer is the #1 field failure — always spec HVY below 0 °C.
How long do the magnets last?+
Neodymium magnets hold 95 %+ of their pull force for 30+ years at room temperature and 20+ years in a -30 °C freezer. The failure mode is the EPDM gasket hardening from plasticiser migration (10-15 yr lifespan) — AERSTER replaces the full seam-gasket assembly during AMC at ₹2,400 per door when inspection flags it.
How fast does the door close after someone walks through?+
Under 2 seconds from full-swing-open on both SLIDE STD and SLIDE HVY. The magnets pull the panels together once the swing arc crosses 30° from closed, and the seam clicks shut with a ~1 kg pull force along the centre line. Much faster than the 8–12 second fall-back time of a hooked strip curtain.
Are magnetic PVC doors food-grade and FSSAI compliant?+
Yes — AERSTER SLIDE panels carry IS 2508 food-contact certification, FSSAI cold-chain compliance, and REACH plasticiser declaration. Every door ships with a material test report (MTR) and a monthly-inspection template for HACCP auditors. Most pharma / food-processing sites install SLIDE specifically for the audit paperwork.
How much clearance do the panels need to swing open?+
Leave at least 300 mm clear on each side of the door frame for the full 110° swing. Walls, racks, parked pallets or permanent equipment inside the 300 mm arc will jam the panels and damage the pivot pin. Check the swing drawing before install — most site-fit issues trace back to racks added after door commissioning.
Can I install a magnetic PVC door in a pharma cleanroom?+
Yes — SLIDE doors hold a 15–25 Pa pressure differential between pharma grade D and grade C zones when panels are correctly sized. Pharma buyers specify the 8 mm HVY panels with the 18-magnet seam for positive-pressure reliability, and order an IQ/OQ protocol on the same PO (available via /contact).
How do I install a magnetic PVC strip door?+
Surface-mount the anodised-aluminium top rail centred over the opening using the supplied bracket and anchor bolts; recessed mounting needs a 160 mm ceiling void. Power is not needed — the door is 100 % mechanical. AERSTER includes a free first-install visit on all SLIDE orders above ₹20,000 through the 120+ dealer network.
What is the warranty on AERSTER SLIDE doors?+
All SLIDE doors ship with a 3-year comprehensive warranty covering panels, magnets, EPDM gasket and rail hardware. Pivot bearings carry a separate 100,000-cycle guarantee (replace-if-fails within the warranty window). Optional AMC plans from ₹1,499/year cover annual lubrication + inspection + seam integrity check.
Does a magnetic PVC door purchase qualify for GST input-tax credit?+
Yes. AERSTER bills SLIDE doors under HSN 3920 at 18 % GST. Registered businesses can claim full ITC on the tax component. Each door ships with a GST-compliant e-invoice, and multi-site orders support HSN-wise reporting for procurement teams.
