Ultra DX

Ceiling-mounted unit for heating or cooling with refrigerant heat exchanger

The Ultra DX operates with the environmentally friendly refrigerant CO₂ and is optimally designed for use in retail stores to efficiently utilize the waste heat from commercial refrigeration.

Air outlet

The air outlet of the Ultra DX is possible on all 6 sides of the casing. The adjustment of the fins determines the direction in which the conditioned air is directed. This ensures optimal air distribution for heating and cooling and a comfortable indoor climate.

Refrigerant CO₂

The Ultra DX uses the natural refrigerant CO₂ (R-744), which stands out due to its very low global warming potential (GWP 1) and its long-term future-proofing.

Model sizes

With its low installation height, the product range of the Ultra Unit Heaters gives you complete design freedom. For operation with refrigerant, the unit is available in size 96.

Installation options

Even in room heights between 2.3 m and 4 m, the Ultra DX ensures optimal air introduction without drafts.

Application areas

The unit is suitable for all retail stores that want to actively utilize the waste heat from "commercial refrigeration".

Timeless design

The Ultra DX Unit Heaters stand out with their timeless design. Its distinctive feature is the hexagonal casing.

Easy Maintenance

The unit is very maintenance-friendly. The bottom cover is easy to remove for maintenance. This makes the plastic condensate tray with externally mounted pump sump and drain connection easy to access.
