Backed to scale.
Tequs is backed by Eviny, Momentum, Kongsberg Innovation, StartupLab and Hafslund, alongside a 1 MEUR Research Council grant. Our sales pipeline has grown 7.5x in twelve months, with €15M in active deals.
The goal is straightforward: take the platform from Norway to Europe and the US, and make burning obsolete as the way the world makes heat.
Recognition.
A world first in CO₂ heat pump technology
Tequs becomes the first manufacturer to achieve Ecodesign certification for high-temperature, water-to-water CO₂ heat pumps.
Cutting district heating consumption by 36%
A Tequs CO₂ heat pump combined with hybrid solar panels is helping AdO Arena produce approximately 700,000 kWh of thermal energy annually.
Award-winning zero-emission energy system
Tequs heat pumps are at the heart of Norway’s first zero-emission energy system for greenhouse production.
