❓ Frequently Asked Questions

Which air curtains does the double-door-sensor fit?
The double-door-sensor is engineered for Chronovex air curtains across the Standard, Premium, and Advanced series (CRCA / Aluminium / SS304 body variants). It also fits most pan-India third-party brands with similar architecture (Almonard, Glamair, Crompton legacy units, Bajaj Industrial, etc.) where the shaft dimension, mounting points, and electrical rating match. Send a photo of your existing part on WhatsApp +91 99977-78202 for fit confirmation before bulk PO — we will verify against your serial number.
How do I know when the sensor needs replacement?
Sensors typically last 5–6 years in 24x7 commercial use. Replace when you observe: false triggers (curtain turning on with no foot-traffic), missed triggers (curtain not responding to slow-walking customers or wheelchair users), reduced range (door has to be approached very close to trigger), or visible lens haze / cracks. Old PIR-only sensors should be upgraded to active-IR for reliable wheelchair / dark-clothing detection.
What is the price-difference between genuine OEM and unbranded marketplace replacements?
Marketplace generics typically price at 40–60% of OEM. The real cost difference shows up at the service call 6–12 months later when the wrong-spec part fails and damages adjacent components. A ₹300 cheap motor that fails and destroys a ₹1,800 blower has cost ₹2,100 total versus an OEM motor at ₹800 that lasts 3 years. For AMC contractors managing 50+ installs, the OEM premium is offset within the first quarter by reduced repeat service-call rate. We also supply with declared electrical ratings and traceable thermal-cutout calibration, which marketplace generics often misrepresent.
How is the double-door-sensor priced for AMC contractors and service workshops?
Retail (1–9 units) at standard list price; bulk (10–49 units) at ~10–15% discount; AMC stocking pack (50+) at workshop-level pricing with consignment-stock options for multi-location contractors. We also offer emergency-spare overnight-courier dispatch from our Noida facility for critical-spare needs. Send your typical monthly consumption volume on WhatsApp +91 99977-78202 for a custom AMC pack quote.
What HSN, GST rate, and tax-invoice format do you provide?
HSN <strong>8536 50 90</strong> · GST <strong>18%</strong>. Electrical apparatus for switching and protection falls under HSN 8536 50 in Chapter 85. Every invoice carries IRN, signed QR (e-invoice as per CBIC mandate for B2B above the prescribed turnover threshold), our GSTIN, and HSN — fully eligible for buyer-side GSTR-2B auto-reconciliation. Input Tax Credit (ITC) is admissible for registered B2B buyers using these parts in the course of business.
What warranty do you provide on spare parts and how do I claim?
6-month manufacturer warranty on the double-door-sensor from invoice date covering manufacturing defects. Wear-and-tear (bearings, lens haze, ABS yellowing in unusual UV-exposure conditions) is excluded. Send service requests on WhatsApp <strong>+91 99977-78202</strong> with photo + original invoice; we respond within one business day. For AMC contractors we operate a fast-track defective-return scheme — ship the defective part back and we courier the replacement within 48 hours.

Standard vs Premium vs Advanced — what actually differs

For a given size, all three deliver the same airflow, wattage and CFM. The difference is not the specification — it is the grade of the components behind it. A 100% copper motor can be sourced at very different price points; the rating stays the same while life, durability and support do not. That grade is what separates these three series, and the onsite warranty reflects it.
