Turnkey HVAC & Cleanroom Solutions
Since 2001, Lotus Airtech has designed, manufactured, installed, and commissioned HVAC and modular cleanroom systems for pharma, hospital OT, textile, food, automobile, warehousing, solar manufacturing, and chemical facilities across India.
Trusted across India's most regulated production floors
From a single AHU retrofit to a 50,000 sq.ft. cGMP facility, every project is delivered by our in-house design, fabrication, and commissioning teams.
Different industries impose different rules — particle counts, RH stability, ATEX zones, ACH ratios. We design to the rule that actually applies to your plant.
Validated air systems for tablet, capsule, injectable, and API facilities — designed to WHO-GMP, Schedule M, and EU Annex 1.
Every project moves through the same six-stage rhythm. Drawings, validation reports, and handover packs are produced inside each stage — not stitched together at the end.
On-site walkthrough, load assessment, and constraint mapping for ducting, electrical, and structural routing.
Heat-load calculation, duct routing, P&ID, GA drawings, single-line electricals, and BMS schematics.
OEM equipment from Daikin, Voltas, Carrier, Munters, Camfil partners — vetted for spec, lead time, and warranty.
In-house panel fabrication, on-site erection, ducting, piping, electricals, and equipment positioning.
Differential pressure mapping, ACH balancing, HEPA integrity, IQ / OQ / PQ documentation, audit walk-through.
24×7 service desk, scheduled preventive maintenance, spare parts inventory, and annual energy audit reports.
A small selection of recent work. Every project listed here has been signed off, validated, and is in production.
Six things that show up on every project — and that procurement, QA, and plant teams cite when they refer us forward.
Design, drafting, and HVAC simulation done internally — no subcontracted design risk, no version-control surprises.
One contract from concept to commissioning. No three-vendor coordination meetings. One accountable team.
Authorised channel partner with Daikin, Voltas, Carrier, Munters, Camfil and others — current pricing, warranty, and spares.
IQ / OQ / PQ, DP mapping, HEPA integrity, ACH reports — handed over on day one, not chased post-handover.
Site teams mobilised across Gujarat, Maharashtra, Karnataka, Telangana, Tamil Nadu, and NCR — with local supervision.
Average response under 4 hours in metros, 12 hours pan-India. SLA-backed, with a dedicated service desk.
They delivered our 18,000 sq.ft. sterile facility two weeks ahead of schedule. The validation paperwork was airtight when our auditor walked in.
