Heat Recovery Systems
Our patented heat recovery ventilation systems capture and reuse thermal energy from exhaust air. This technology achieves 50% energy efficiency improvements while maintaining indoor air quality. Designed for commercial kitchens and industrial processes, these systems reduce operational costs and carbon footprints. The counter-flow heat exchanger core ensures optimal performance with minimal maintenance requirements.
Kitchen Extraction
Bespoke kitchen canopy systems remove cooking fumes and heat while maintaining hygiene standards. Our TR/19-compliant designs integrate make-up air solutions to balance airflow. Custom stainless steel constructions meet DW/144 specifications for commercial kitchens in restaurants, hotels, and food production facilities.
LEV Testing
Local exhaust ventilation assessments ensure compliance with HSG 258 guidelines. We conduct thorough system evaluations, including airflow measurements and control measures for hazardous substances. Our certified engineers provide detailed reports and remedial recommendations for industrial and laboratory environments.
Fan Wall Systems
Modular fan arrays deliver redundant, energy-efficient air handling solutions. Using EC motor technology and intelligent controls, these systems maintain consistent airflow in critical environments. The scalable design allows individual fan maintenance without system shutdown, ensuring continuous operation in hospitality and healthcare settings.
Anti-Vandal Louvres
Robust steel louvre systems provide secure ventilation for plant rooms and commercial premises. Custom-fabricated with welded corners and optional bird mesh, these units combine 24/7 airflow with forced-entry resistance. Available in powder-coated finishes to match building aesthetics while meeting security standards.
