These duct assemblies are constructed using 43mm thick PUF insulated panels with anodized aluminium frames. The paneling consists of pre-coated galvanized iron for the exterior surface and plain GI for the interior surface. These duct assemblies can be easily transported in dismantled form and installed on-site without difficulty.

The PUF insulation has a density of 40 kg/cu.mtr. Sections of the ducting can include cooling coils, heating coils, or steam coils with 2, 4, 6, or 8 rows. SS 304 insulated coil trays are integrated with mist eliminators and proper drain traps. Coil face velocity within the ducting will not exceed 500 fpm. Centrifugal fans from KRUGER/NICOTRA are incorporated into all ducting units and are AMCA certified.

These duct assemblies also feature direct drive fans compatible with BMS systems to optimize energy use. Three-phase induction motors (Eff-1 & 2) from CG/ABB/Kirloskar power all ducting fans. Centrifugal blower and motors are mounted on a single base frame with spring/rubber anti-vibration isolators. Door limit switches automatically stop the fan/motor when any ducting service door is opened. All ducting service doors are equipped with aluminium die-cast hinges and nylon handles. The ducting units are mounted on 16G GI / 100x50mm MS channel base frames according to size and can be dismantled for transport. Custom filtration levels are provided as per requirement.

Single Wall Ducting Modules – Ground Level

These duct modules are fabricated from 16G/18G pre-coated or powder-coated GI sheet panels with anodized aluminium structure. The duct modules are modular and can be dismantled for easy transport and installation.

Centrifugal fans of KRUGER/NICOTRA make are used in all ducting assemblies and are AMCA certified. Direct drive fans compatible with BMS systems are included to conserve energy. Three-phase induction motors (Eff-1 & 2) from CG/ABB/Kirloskar power the fans in all duct modules.

Centrifugal blowers and motors in the ducting are mounted on a single base frame with suitable drive assemblies and spring/rubber anti-vibration isolators. Door limit switches automatically stop the fan/motor when ducting doors are opened. Ducting access doors feature aluminium die-cast hinges and nylon handles. All ducting is mounted on 16G GI / 100x50mm MS channel base frames according to size and capacity and can be dismantled for relocation. Custom filtration levels are incorporated as required.

Evaporative Cooling Duct Systems – Ground Level

These duct systems are fabricated from 16G/18G pre-coated or powder-coated GI sheet panels with anodized aluminium structure. The duct systems are modular and can be transported in dismantled condition and installed on-site easily.

Evaporative cooling pads are incorporated into the ducting along with SS water tanks, mist eliminators, mono-block pumps, and necessary piping and controls. Evaporative pad face velocity in the ducting will not exceed 500 fpm. Centrifugal fans of KRUGER/NICOTRA make are used in all ducting systems and are AMCA certified. Direct drive fans compatible with BMS systems are included for energy efficiency. Three-phase induction motors (Eff-1 & 2) from CG/ABB/Kirloskar power the ducting fans.

Centrifugal blowers and motors are mounted on a single base frame with spring/rubber anti-vibration isolators. Door limit switches automatically stop the motor/fan when ducting service doors are opened. All ducting doors are fitted with aluminium die-cast hinges and nylon handles. All ducting systems are mounted on 16G GI / 100x50mm MS channel base frames according to size and capacity and can be dismantled for transport. Custom filtration levels are provided as required.
