• DUEX ® Industrial Systems is established in 1994 with motto of energy saving on reliable principle methods. Our products are designed under guidance from IIT, Mumbai technologists. We are located in Mumbai, with dealer network all over India. Our Mumbai office is situated in industrial complex with design setup and pilot plant. Apart from panel fabrication and powder coating else is done in-house including design, coil winding, electrical and electronics assembly, testing, inspection and final dispatch. We are in forefront of development in lighting energy saving field and come up with latest Mag-Amp SCENE model. This model is especially designed for high-end requirements with advanced flux induction principle for achieving more energy saving by maintaining lumen at steady level. It's micro controller panel lets user set many parameters and fine tune the system with never before 7 time zones, almanac timing, 255 level lumen settings.
  
• AHU with variable air volume (VAV) is today's trend to optimize system performance from the energy consumption point of view. Dehumidifier with unique energy saving technology with desiccant bed rotor reduces humidity down to 1% RH no other technology can offer. Heat Recovery Ventilators play very vital roll in AHU wherein stale air is exhausted and fresh air is supplied in without loss in cooling energy with better tha 80% effciency (read more below). This unique HRV core is without any moving parts with life is more than 40-50 years. Pharma, food, wood, electronic, shopping malls, commercial complexes are mainly covered
  
• In this global situation where water scarcity killing thousands due to unhygienic water. Purest water is available by water from air system which extracts water from atmosphere.
  
• We have got prestigious ISO 9001:2000 certification, also we are SSI registered company. We cater needs of government, private sector and export requirement. Our manufacturing product range includes:
  
  Our Products are:
  01.  Lighting energy saving (LES)    
  02.  AHU/Dehumidifier (AHU/DH)
  03.  Ultrasonic Cleaner (USC)
  04.  Heat Recovery Ventilator (HRV)

HEAT RECOVERY VENTILATOR (HRV)

DUEX has sold many HRV based on heat transfer principle, wherein exhaust and fresh air are passed opposite in direction in alternate isolated paths. This core is imported from Australia. Heat transfer efficieny is better than 80%.

Adavtages over heat/energy recovery wheel :

a) No rotating parts in core b) More than 40 years life (wheel need to replaced or cleaed periodically) c) No part replacement or maintenance required d) Efficiency better than 80% (in wheel it is 50% and reduces drastically over 8-10 months) Stale Outlet Exhaust and Fresh Inlet Supply air are 100% isolated (in wheel it is 60-80%)
