At least as wide as the door, ideally 100 mm wider on each side. For doors above 7 ft, install two units side-by-side and switch them together so the seal is uninterrupted.
No — they work together. The air curtain deflects 90–95% of insects at the entrance; the insect killer handles whatever gets in. Both are usually required for FSSAI compliance in food businesses.
Typical savings range 30–60% of the cooling lost through that doorway. For a busy restaurant entrance, that often translates to ₹8,000–18,000 a month. Payback under 12 months is normal.
Standard-series units run 60–66 dB(A) at full speed. The Silent series sits at 50–55 dB(A) — quieter than typical office HVAC. Most have multi-speed motors so you can run quieter when traffic drops.
A confident electrician can mount and wire most models in 2–3 hours. We provide installation guides, mounting hardware, and a phone-support number. Professional on-site installation is available across Indian metros for around ₹2,500 per unit.
Almost never. Heated curtains add a 3–9 kW load and are designed for European winters. In India, ambient curtains perform identically for thermal sealing — no winter use case justifies the running cost.
Standard series: 2 years on parts, 1 year on motor. Premium: 3 years comprehensive. Advanced: 5 years comprehensive with on-site replacement in metros. All warranties cover manufacturing defects, not water damage or unauthorised modifications.
Yes. Air curtains are typically wired to a 6–16 A circuit; a 4 ft unit draws around 200 W. You can run 2–4 units on a single dedicated circuit. For coordinated start/stop, use a shared contactor or a smart-switch.
