Services
Industrial Ventilation
We design and install industrial ventilation systems to control airborne contaminants, ensuring compliance with COSHH regulations. Our solutions improve air quality in manufacturing plants, warehouses, and commercial buildings. Systems are tailored to meet specific operational needs, reducing health risks and enhancing workplace safety.
LEV Testing
Our BOHS P601-certified engineers conduct thorough LEV testing every 14 months to ensure systems meet legal requirements. We identify performance issues and provide engineering reports for improvements, guaranteeing ongoing compliance and worker safety in industrial environments.
Evaporative Cooling
We supply energy-efficient evaporative cooling systems that reduce temperatures by up to 90% compared to traditional air conditioning. These systems use natural evaporation, cutting energy costs and carbon emissions while maintaining fresh air circulation in large industrial spaces.
Air Conditioning
Our air conditioning installations include split systems and VRV units designed for commercial and industrial use. Systems are CE-marked, ozone-friendly, and backed by manufacturer warranties, ensuring reliable climate control for offices, factories, and public buildings.
Industrial Heating
We provide radiant and warm air heating solutions for large spaces with high ventilation demands. Systems use gas or oil-fired heaters to target specific areas efficiently, reducing energy waste in warehouses, workshops, and agricultural facilities.
