Integrated Filtration: Includes a G4 filter for reliable contamination protection.
Expanded Capabilities: Beyond Geothermal
Our solution offers unparalleled flexibility. It can function as a traditional ground-loop pre-conditioner or seamlessly integrate directly into modern building heating systems.
Geothermal Frost Protection
The brine in the ground collector absorbs steady soil temperatures, preventing the primary ventilation heat exchanger from freezing in winter without electric defrosting.
Low-Temp Duct Water Heater
Connect directly to a building's low-temperature heating system (e.g., heat pumps, underfloor heating at 25–40°C) to efficiently post-heat supply air and reduce operating costs.
Absolute Energy Efficiency
By utilizing existing heat sources (ground loops or warm water), the need for additional electric heating devices is eliminated, guaranteeing a comfortable indoor climate year-round.
Heat Pump Integration
(No Ground Loop Required)
Cannot install a dedicated geothermal ground loop? GHT modules seamlessly integrate directly into central Air-to-Water or Geothermal Heat Pump systems via a standard buffer tank. This approach is highly popular in advanced US residential and commercial designs.
How It Works in Practice:
-
🌡️
Direct Buffer Tank Feed: The GHT unit receives unmixed water directly from the central HP buffer tank (e.g., 50°F / 10°C in Summer, 125°F / 52°C in Winter). Crucial Freeze Protection: In cold climates, pure water cannot be routed to the intake air coil. A glycol solution (or an intermediate plate heat exchanger separating the tank's water from the GHT glycol loop) must be used to prevent coil bursting during circulation pauses.
-
🎛️
Hybrid Stage Control: Perfect for pairing with radiant floors. The radiant floor acts as 1st stage heating, while the GHT unit acts as 2nd stage heating and primary Summer cooling, all operated by standard thermostats (e.g., Tekmar).
-
⚙️
Precise Flow Management: Easily managed by a single zone circulator. Standard flow setters at the GHT unit ensure exact hydronic flow requirements are met.
