Solid refrigerants.
Conventional cooling.

Our solid refrigerants heat and cool under changing pressures within the range used by traditional gas refrigerants. This offers a path to more efficient cooling using familiar components and non-flammable materials that stay inside the system.

Designed for real systems.

Two solid refrigerant cartridges alternate between heating and cooling. Pressure drives the cycle, while airflow moves heat out of the cooled space and into the room.

Beverage cooling first. Then the rest of HVAC.

We’ve built four fully functional solid refrigerant cooling systems and are preparing for commercial pilots in beverage refrigeration.

A beverage fridge cools a box. An air conditioner cools a room. Same idea.

Both move heat from where you don’t want it to somewhere else. In Pascal’s system, CO₂ serves as the working gas that applies pressure to our solid refrigerant materials.

What we develop here will be applied to other cooling systems, including air conditioning, industrial chillers, and data centers.
