Capabilities

Engineering Innovation Beyond Convention WITT UK Group’s Specialist Applications division tackles ventilation challenges that defy standard solutions, delivering pioneering air movement systems for Britain’s most iconic structures and complex industrial processes. From Wembley Stadium’s revolutionary pitch ventilation to the National Grid’s critical infrastructure cooling, from warehouse destratification saving millions in energy costs to bespoke solutions for automotive car stackers—we transform unique challenges into engineered success stories. Our team combines decades of aerodynamic expertise with innovative thinking, creating solutions that often establish new industry benchmarks. Whether addressing thermal stratification in 30-metre high distribution centres, managing diesel fumes in underground bus stations, or ensuring year-round comfort in glass-fronted architectural masterpieces, we deliver systems that perform beyond expectations.

Comprehensive Problem-Solving Expertise  Our specialist applications leverage advanced computational fluid dynamics (CFD) modelling to visualise and solve complex airflow challenges before manufacture begins. We understand that effective ventilation extends far beyond simple air movement—it’s about energy efficiency, occupant comfort, process optimisation, and regulatory compliance. Our portfolio includes destratification fans reducing heating costs by up to 40%, lobby ventilation systems preventing stack effect in high-rise buildings, loading bay air curtains maintaining temperature control, and bus station extraction systems meeting stringent air quality standards. Each solution undergoes rigorous analysis considering thermal dynamics, air quality requirements, acoustic constraints, and energy consumption, ensuring optimal performance whilst minimising operational costs.

Frequently

Asked Questions

What is destratification and how much can it save?
Destratification eliminates temperature layering in high-ceiling spaces where warm air accumulates at roof level—wasting energy and creating uncomfortable conditions. Our destratification fans gently recirculate this warm air back to floor level, achieving typical energy savings of 30-40% on heating costs. In a 15-metre high warehouse, temperature differentials can reach 10°C from floor to ceiling—our systems reduce this to under 2°C, dramatically improving comfort whilst reducing energy consumption.
Transport hub ventilation requires sophisticated solutions managing diesel fumes, passenger comfort, and regulatory compliance. We design systems incorporating: pollution sensors monitoring CO/NOx levels, variable-speed extraction responding to vehicle movements, jet fans providing longitudinal ventilation, and make-up air systems preventing negative pressure. Our bus station installations meet UK air quality standards whilst minimising energy consumption through demand-controlled ventilation.
Glass-fronted buildings present unique challenges including solar gain creating excessive heat, cold downdrafts from glass surfaces, condensation risk on cold surfaces, and aesthetic requirements limiting equipment visibility. Our solutions incorporate: displacement ventilation managing thermal loads efficiently, perimeter heating preventing downdrafts, automated controls responding to solar conditions, and architecturally integrated equipment preserving design aesthetics. Projects range from corporate atriums to botanical gardens requiring precise climate control.
Stadium ventilation extends beyond spectator comfort to include pitch condition management crucial for grass growth and match playability. Our Wembley Stadium system exemplifies this complexity, incorporating: pitch ventilation ensuring grass health year-round, bowl ventilation managing 90,000 spectators, concourse smoke control for emergency scenarios, and kitchen/hospitality extraction systems. Each zone requires different strategies, from displacement ventilation in seating areas to high-velocity systems for pitch aeration.
Stack effect occurs in tall buildings where temperature differences create powerful vertical air currents, causing lobby doors to malfunction, lifts to whistle, and energy loss through uncontrolled air movement. Our lobby pressurisation systems combat this using: pressure sensors monitoring building dynamics, variable-volume supply fans maintaining optimal pressure, airlock vestibules controlling entrance conditions, and elevator shaft ventilation preventing pressure differentials. Properly designed systems eliminate door problems whilst improving energy efficiency.
Yes, all our specialist applications integrate seamlessly with Building Management Systems (BMS) via BACnet, Modbus, or other protocols. Integration enables: real-time monitoring of air quality and temperatures, automatic adjustment to occupancy patterns, energy optimisation through demand-controlled ventilation, predictive maintenance using performance trending, and remote adjustment and fault diagnosis. We provide complete control philosophy documentation and operator training, ensuring facilities teams maximise system capabilities whilst minimising operational costs.
