THE TERRA FUTURA GEOTHERMAL PROBE
The Terra FUTURA geothermal probe is a component of the Prawtech Geothermal ground source system for GSHPs. The exchanger consists of a plastic geothermal u-shaped head connected by polyfusion with HDPE 100 RC collector pipes. The probe has been designed to optimize the process of applying the heat exchanger to the borehole and increase the operational safety of the ground heat source installation. Modern probe production technology is based on the highest quality raw materials and constant quality control of production and logistics processes.
The FUTURA probe has been designed to guarantee ergonomics and safety during its installation. The external dimensions of the u-shaped (see Fig. 1 and Fig. 2) reduce the resistance during application of the exchanger to the borehole, while the wedge shape of the probe makes it easier for the probe to overcome individual soil layers and securely locate it at the designed depth as well as the discharge of the drilling mud from the borehole. An integral part of FUTURA probe is a technical socket with an internal diameter of DN=30mm. It is designed to provide axial and parallel application of the exchanger into a borehole. The FUTURA also enables optional grouting of the borehole. The PRAWTECH probe head has a monolithic design and is entirely created during an automated production process monitored by the Golem supervisory system. The PRAWTECH probe production control system belongs to the MES group (Manufacturing Execution System), i.e. systems collecting production data in real time, allowing for the analysis of production and control of running production orders, taking into account the optimization of planning.
The Prawtech geothermal probe is available as standard in two pressure types:
● Pn 12.5 (SDR 13.6): the application depth of the exchanger must not exceed 120 meters;
● Pn 16 (SDR 11): the maximum depth of the borehole and the application of the exchanger may not exceed 200 meters, in individual cases it is possible to use the probe for deeper boreholes after written consultation with a geologist, designer and manufacturer.
And in two dimensional standards:
● 2 x 40mm: the collector pipes are then made of high density polyethylene PE100 RC (Crack resistant) with an external diameter of 40 mm each;
● 2 x 32mm: the collector pipes are then made of high density polyethylene PE100 RC (Crack resistant) with an external diameter of 32 mm each.
All PRAWTECH geothermal probes are delivered to the customer only with positive pressure and flow tests results in accordance with the in-house quality control procedure.
Each exchanger has its own individual serial number.
PRAWTECH TERRA 90 PROBE
The current offer of Prawtech GEOTHERMAL probes also includes the Terra 90 series probe. The product is a component of the ground source system for GSHPs. The exchanger consists of a plastic geothermal head that forms a monolithic structure with HDPE 100 RC pipes. The head has an additional cover with an outer diameter of 90mm, filled with a concrete mixture with sealing properties. An integral part of Terra 90 probe is a technical socket with an internal diameter of DN=27mm. It is designed to provide axial and parallel application of the exchanger into a borehole. The probe has been designed to optimize the process of applying the exchanger to the vertical borehole and increase the operational safety of the ground heat source installation. The modern probe production technology is based on the highest quality raw materials and constant quality control of production and logistics processes.
The probe head enables an optional bottom-up borehole grouting.
The Prawtech geothermal probe is available as standard in two pressure types::
● Pn 12.5 (SDR 13.6): the application depth of the exchanger must not exceed 120 meters;
● Pn 16 (SDR 11): the maximum depth of the borehole and the application of the exchanger may not exceed 200 meters, in individual cases it is possible to use the probe for deeper boreholes after written consultation with a geologist, designer and manufacturer.
And in two dimensional standards:
● 2 x 40mm: both collector pipes are made of high density polyethylene PE100 RC resistant to crack propagation with an external diameter of 40mm each;
● 2 x 32mm: both collector pipes are made of high-density polyethylene PE100 RC resistant to crack propagation with an external diameter of 32 mm each.
On special request of the customer, the probe is also available in the configuration of the so-called double U-shape i.e. in the arrangement of 4 x 32 and 4 x 40mm.
All PRAWTECH geothermal probes are delivered to the customer only with positive pressure and flow tests results in accordance with the in-house quality control procedure.
Each exchanger has its own individual serial number.
