Services
Air Curtains
Air curtains create invisible barriers at entrances, preventing uncontrolled air exchange while maintaining temperature and air quality. Our units reduce energy costs by up to 30% in retail, hospitality, and industrial settings. Customisable options include vertical, recessed, and warehouse-specific designs with ambient, electric, or LPHW heating variants.
Air Handling Units
Custom-built air handling units manage ventilation and climate control in commercial buildings. Available in compact and large configurations, they feature low-noise operation and energy recovery systems. Applications include hospitals, data centres, and retail spaces requiring precise air filtration and temperature regulation.
Destratification Units
Destratification fans optimise heating efficiency by circulating warm air from ceilings to occupied zones. Reducing energy consumption by up to 40%, these units are ideal for warehouses, sports facilities, and industrial spaces with high ceilings. Available in three performance tiers with remote control options.
HVAC Refurbishment
Refurbishment services extend AHU lifespan while cutting costs by up to 70% compared to replacements. We upgrade components like filters, fans, and heat exchangers, ensuring compliance with modern efficiency standards. Projects include phased installations to minimise operational disruption in critical environments.
Commercial Heating
Electric and LPHW heating systems tailored for large commercial spaces. Products include stock room heaters, under-roof units, and energy-efficient models for warehouses and distribution centres. Systems integrate with BMS controls for automated temperature management in storage and manufacturing facilities.
