⚙️ Specifications

✨ Key Features

• 🔥 Heater-ready (optional) — plug-in 3 kW / 6 kW PTC ceramic heater module turns the unit into a warm-air curtain for winter use in factory entries and cold-storage doors.
• 🔧 Industrial-grade build — reinforced 1.0 mm powder-coated steel body, heavy-duty 2-motor setup rated for 18-hour continuous operation.
• 💨 High-velocity jet — jet reach up to 3.5 m at 16 m/s outlet velocity — seals doors against strong wind, monsoon draft and pressure differentials.
• ❄️ Cold-chain seal — stops cold air from escaping cold-storage / blast-freezer doors; cuts compressor cycling by 30–40%.
• 🦟 Insect, fume & dust block — 2,000 CFM continuous barrier stops flies, kitchen fumes, road dust and PM2.5 from drifting through the open doorway.
• 🛡️ 3-year extended warranty — industrial-grade build comes with extended 3-year warranty (vs 1-year on Standard / Premium).

📍 Who Should Buy This?

• Shopping malls & multiplexes — main entry doors up to 1.2 m wide
• Factory & warehouse gates — production-floor entries with constant forklift traffic
• Cold storage & blast-freezer doors — needs heater-off cold-chain seal
• Food processing & dairy plants — FSSAI-compliant fly/pest barrier at production entries
• QSR kitchens & cloud kitchens — high-fume / high-heat back-door entries
• Hospitals & pharma plants — positive-pressure ward and clean-room entries

🛠️ Installation Notes

• Mount horizontally above the door frame, height 2.3–3.3 m (lower = stronger barrier).
• Air jet should point slightly outward (5–10°) to deflect incoming flies/dust.
• Plug into a dedicated 5 A / 220 V outlet — no rewiring needed.
• Test high mode first (2,000 CFM), then low mode for off-peak hours.
• Clean filter grille every 30 days (dust load varies by location).

❓ Quick FAQ

Q. Does the heater come pre-installed in the Advanced 4 Feet?
No — the heater port is built in, the PTC heater module ships as an optional accessory (3 kW or 6 kW). For unheated use (mall entries, factory gates) the unit works as a standard high-velocity air curtain.

Q. How is Advanced different from Standard 4 Feet?
Advanced uses a reinforced 1.0 mm steel body (vs 0.7 mm Standard), heavy-duty industrial motors rated for 18-hour duty, higher outlet velocity (16 m/s vs ~12 m/s Standard), heater-port readiness, and a 3-year warranty (vs 1-year). Standard is built for retail; Advanced is built for industry.

Q. Can I run this 24/7 in a factory?
Yes. The Advanced series is rated for 18-hour continuous operation per day. For true 24/7 use across multiple shifts, we recommend dual units mounted side-by-side on rotational duty cycles — our application engineer can spec this on a call.

🏅 Manufacturing & Quality

Chronovex Industries Pvt. Ltd. manufactures every air curtain at our ISO 9001:2015 certified facility in Noida, Uttar Pradesh. Each 4ft Aluminium Advanced unit passes 12 QC checkpoints — motor balancing, blower alignment, voltage stability (200–240 V tolerance), thermal cut-off testing, noise level (≤65 dB at 1 m), and a full 30-minute run-test before packaging.

⚙️ Why buyers pick the Advanced 4 Feet over Standard / Premium

Three reasons. First, the heater port — plug in the optional 3 kW or 6 kW PTC module and the unit becomes a warm-air curtain for winter use, critical for cold-storage rooms (keeps frost off the doorway) and factory entries in north India where January temperatures drop below 5 °C. Second, the reinforced 1.0 mm steel body and heavy-duty motors rated for 18-hour continuous operation — retail-grade Standard / Premium units burn out under industrial duty cycles. Third, the 3-year warranty — our procurement-team conversations consistently show that factory and mall buyers won’t buy a 1-year-warranty curtain for a 24/7 doorway. If your application is industrial, food-processing, cold-chain or mall-traffic, Advanced is the only Chronovex line built for it.
