Roll-bond Evaporators

The most efficient evaporators for commercial and household refridgeration systems.

The most efficient evaporators

Roll-bond evaporators provide uniform refrigerant distribution and a significantly larger active heat transfer surface, resulting in superior thermal efficiency.
Their lightweight aluminium construction enables faster cooling performance, lower energy consumption, and improved temperature stability throughout the refrigeration system.

OSEF & DSI Roll-Bond Technology

We design and manufacture Roll-bond evaporators in OSEF (One Side Extra Flat) and DSI (Double Side Inflated) configurations. Depending on your application requirements, evaporators can be produced with single-side or double-side inflated channels to optimize surface flatness, heat transfer efficiency, and overall cooling performance.
