Custom HVAC for every sector.

Hotel HVAC must deliver guest comfort without acoustic intrusion — noise from FCUs and AHUs directly affects room ratings and reviews. Zonex supplies ceiling fan coil units for guest rooms, floor-mounted AHUs for lobbies and banquet halls, and dedicated fresh air units for F&B kitchens and service areas. All systems are selected to ASHRAE standards and sized for India's peak summer conditions.

Operation theatres, ICUs, and pharmaceutical manufacturing demand controlled positive or negative pressure, EU-7 to HEPA filtration, and tight temperature/humidity tolerances. Zonex horizontal floor-mounted AHUs with thermal break panels and heat recovery wheels are the standard specification for these environments. Selection reports, GA drawings, and factory test certificates accompany every unit.

Large open-plan retail and entertainment venues require high-capacity, energy-efficient central systems that can be zoned per tenant and occupancy profile. Ceiling-suspended AHUs handle low plant-room heights; pad-type air washers supplement cooling during shoulder seasons. Axial flow fans manage car park ventilation and stairwell pressurisation per NBC 2016.

Commercial kitchens and food production floors generate grease-laden, humid exhaust air that corrodes standard equipment. Zonex corrosion-resistant air scrubbers (wet and dry type) handle odour and particulate removal from restaurant and FMCG kitchens. Air washers provide supplemental evaporative cooling in production halls with high internal heat loads.

Assembly plants require large-volume general ventilation to manage process heat, welding fumes, and paint booth exhaust. Zonex axial flow fans in sizes up to 1,800 mm diameter handle general and emergency ventilation, including high-temperature smoke exhaust rated at 250°C / 300°C for two hours. Air exhaust units serve pit areas and underbody work zones.

Government procurement requires documented compliance — HSN classifications, selection reports, GA drawings, and factory test certificates. Zonex supplies metro stations, railway terminals, and central government offices with floor-mounted AHUs and axial fans built to government technical specifications. Projects are handled on a supply-and-erect basis with complete documentation.

Educational institutions need reliable, low-maintenance HVAC that runs for 10+ years without major overhauls and operates within tight energy budgets. Ceiling-suspended AHUs and fan coil units provide zoned comfort cooling for classrooms, libraries, and auditoriums. Pad-type air washers offer an energy-efficient alternative for canteens and covered outdoor areas.

Commercial towers and mixed-use developments have distinct HVAC requirements at every floor. Chilled water fan coil units provide zone-by-zone comfort control in offices and retail plinths. Axial flow fans — with optional pedestal stands and bird screens — are specified for basement car parks, utility tunnels, and stairwell pressurisation systems.
