HVAC & Geo-Thermal Energy

Value Proposition: Ideal for medium to large commercial facilities

Mimer Energy is a Swedish energy company with an experience of over 3,000 installations across 20 years around the world to provide efficiency strategies for cooling and heating areas

Specially designed Rydell & Lembke Compact Chiller Units (CCUs) deliver very high COP for cooling and heating applications.

Modular in design, they can be stacked to provide the right kind of redundancy for critical no-fail applications like hospitals & data centers

Geo-Thermal Energy, the basics

Working Principle: Outdoor temperatures fluctuate with the changing seasons but underground temperatures don’t change.

A geothermal system, which typically consists of an indoor handling unit and a buried system of pipes, called an earth loop, and/or a pump to reinjection well, capitalizes on these constant temperatures to provide “free” energy
