Understanding the Technology

What is Geothermal Pre-Conditioning?

It is a high-efficiency ground heat exchanger designed for use with heat recovery ventilation (HRV/ERV) units. It acts as a shield—preventing core freezing in winter and delivering free passive cooling in summer.

Winter Geothermal Operation
❄️

Winter Operation

During extreme cold, the system utilizes ground heat at depths of 1.5 to 2.5 meters (where temperatures stabilize at +5°C to +8°C). The module transfers this steady warmth to the incoming freezing air.

  • • Prevents HRV core freezing
  • • Eliminates electric de-icing costs
  • • Up to 8 kW heating from 0.04 kW input
Summer Geothermal Operation

Summer Operation

In hot periods, the process reverses. The brine loop leverages the ground's natural coolness (+10°C to +14°C) to significantly drop the temperature of hot incoming outdoor air before it enters the building.

  • • Passive, low-cost air conditioning
  • • High COP (Coefficient of Performance)
  • • Up to 8 kW cooling from 0.04 kW input

The GHT Advantage

📉

Ultra-Low Power

Unbeatable COP. Consumes only 40 watts while generating up to 8000 watts of thermal capacity.

🛡️

No Thermal Bridges

Housing made entirely of EPP (Expanded Polypropylene) eliminates condensation risks.

⚡

Quick Installation

Very light construction ensures easy handling and rapid deployment on site.

🌬️

Low Pressure Drop

Optimized aerodynamic design reduces the workload on the main ventilation fans.
