M-XM MIXED AIR – DX AIR HANDLING UNIT

In traditional hydronic HVAC systems, whether warm or cool air is delivered to the environment, boilers are required in winter and chillers, pumps, and valves in summer. In contrast, DX HVAC systems can provide conditioning without the need for additional accessories (though they require additional automation equipment).

The unparalleled advantage of DX HVAC systems lies in their ability to transfer heat directly to the air via the refrigerant flow in the DX coil, minimizing energy and heat loss. This makes them a cost-effective solution in terms of initial investment and operational costs in energy-efficient building design and operation. They emerge as the optimal solution in energy efficiency during system energy efficiency comparisons for external unit central systems

Filters
Filters are designed with a frame structure that can be easily removed and installed via maintenance covers on Air Conditioning Units.
Filter frames are made of galvanized sheet metal (painted in hygiene devices) and equipped with spring clips for compressing the filters. The surfaces created by the filters are provided with seals to ensure tightness, and filter cassettes sit on these seals. Holes necessary for the hose connections of pressure gauges indicating the differential pressure of the filter group are drilled in the factory in an appropriate manner
Accessories: Manometer (0-500 Pa)
