Air Source Heat Pump Enclosures and Accessories
Steel enclosures made in Finland for air source heat pump outdoor units
Protect your heat pump’s outdoor unit from the weather and accidental impacts
Durable finish and easy installation. Made from powder-coated, hot-dip galvanised steel, Kiilax enclosures are built to last and easy to clean. They are supplied for straightforward assembly, with mounting accessories included depending on the model. The enclosures can be fitted to a wall or used with a separate ground stand.
Options for different installations. The range includes a standard enclosure, a larger Medium model and extension kits for increasing the enclosure height, and a balcony model with a flat roof and adjustable feet for confined or uneven spaces. Accessories include defrost water guides and mounting kits for ground stands and walls.
Designed for unobstructed airflow. The horizontal openings are sized to allow air to circulate freely around the outdoor unit. Kiilax Oy has commissioned a comprehensive SolidWorks Flow Simulation analysis of the effects of the enclosure and a defrost water guide plate.
