Cooling Indian Industry with Fresh Air & High Efficiency
Headquartered at Nagasandra, Bangalore (near BIEC), Valutech Air Systems engineers and manufactures high-capacity evaporative coolers, gearless PMSM HVLS giant fans, and custom air pollution extraction systems for heavy industries across India.
Bangalore Works Facility
Our specialized manufacturing and assembly facility produces industrial ductable air coolers, PMSM fan assemblies, and CNC ductwork with direct OEM testing and quality assurance.
5-Step Factory Engineering Process
Every Valutech project follows a structured engineering workflow from thermal survey to calibrated airflow balancing.
On-Site Thermal & Airflow Survey
Our project engineers visit your facility to map machine kilowatt heat dissipation, roof truss clearance, worker density, and natural draft patterns.
CFM Engineering & Duct Design
We run ASHRAE air change calculations and pressure drop simulations to size exact CFM requirements and lay out low-resistance duct paths.
Bangalore Works Fabrication
Ducting, plenums, steel mounting brackets, and balancing dampers are fabricated directly at our Nagasandra facility with strict gauge tolerance.
Rooftop Mounting & Erection
Rigorous rigging, leak-proof roof penetrations, water supply plumbing, electrical safety interlocks, and sensor wiring are installed by certified technicians.
Balancing & Commissioning
Final airflow volume balancing with calibrated digital anemometers ensures uniform temperature drops across every workstation and bay.
Heavy Industrial Construction Standards
Engineered to operate reliably under 45°C ambient temperatures, high humidity, and continuous factory duty cycles.
UV-Stabilized Copolymer Body
Molded heavy-duty industrial copolymer casing engineered to endure harsh rooftop tropical sun, monsoons, and corrosive industrial emissions without chalking or rust.
100% Copper IP55 Motors
Totally Enclosed Fan Cooled (TEFC) motors wound with pure electrolytic copper, fitted with class F insulation and thermal overload sensors for continuous 24x7 duty.
High-Saturation 5090 Pads
Cross-corrugated 100mm/150mm cellulose evaporative media with anti-rot phenolic resin coating, providing >85% adiabatic cooling saturation efficiency.
Aviation-Grade Impellers
Aviation 6061T6 aluminum alloy blades dynamically balanced to ISO 1940 standards for whisper-quiet airflow, high static lift, and zero vibration.
Technical & Engineering FAQs
Answers to frequent questions asked by HVAC consultants, MEP contractors, and factory heads.
How much electricity does a Valutech evaporative cooler consume compared to conventional chiller AC?
Valutech evaporative coolers consume approximately 75% to 85% less power than traditional refrigerant-based industrial air conditioning systems. A 30,000 CMH unit (VAS-30) consumes only 3.0 kW per hour while delivering 17,657 CFM of cooled fresh air, whereas cooling a comparable 2,000 sq.ft industrial floor with central DX or chiller AC would demand 15 to 20 kW/hr.
What is the difference between PMSM Gearless HVLS fans and traditional gearbox HVLS fans?
PMSM (Permanent Magnet Synchronous Motor) fans feature a direct-drive gearless rotor. Unlike conventional geared motors, PMSM fans have no gearbox oil leaks, zero mechanical friction wear, operate under 40 dB(A) whisper-quiet sound levels, and deliver over 1,00,000 operating hours without periodic mechanical maintenance.
Does Valutech manufacture custom ducting, machine extraction hoods, and turnkey systems?
Yes. In addition to standard OEM equipment, our Bangalore works engineers and fabricates turnkey ventilation systems including GI / MS sheet metal spiral and rectangular ducting, air distribution plenums, volume control dampers, laser/welding fume capture hoods, and wet scrubbers.
What water supply and water pressure are needed for VAS evaporative coolers?
VAS coolers connect to standard 1/2" or 3/4" BSP municipal or borewell water lines with an operating pressure of 1 to 3 bar. Each unit includes a built-in submersible water pump, heavy-duty float valve, and automatic water level sensor with dry-run protection to safeguard the pump.
What warranty, commissioning, and after-sales service does Valutech provide?
All Valutech industrial units carry a comprehensive 12-Month Manufacturer Warranty covering the motor, pump, and electrical control systems. Our field engineering team provides on-site factory commissioning across Karnataka, Tamil Nadu, Andhra Pradesh, and Maharashtra, with genuine spare parts stocked at our Nagasandra works.
