Leplan AG


We are specialists for cooling technology in the fields of plant engineering, commercial cooling, and heat pumps/air-conditioning. We intentionally focus on natural cooling agents.

The cooling system is a key component of an energy plan and therefore of the performance and efficiency of the overall system. We know the relevant rules, regulations and ordinances and we deal with a range of cooling agents, their applications and limitations. 

We design cooling systems according to our clients’ wishes. Some clients are chiefly concerned with the investment costs, others are more focused on safety, the system’s environmental impact or on life cycle costs.

Make sure to get in touch with us about your projects in the areas of industrial cooling, ice rinks, ambient cooling, heat pumps and commercial cooling.
