We have three versions of our panel in our catalog:
- SPRING3 and SPRING4 non insulated
- SPRING3 and SPRING4 insulated
- SPRING4 finned
Non insulated SPRING
The non-insulated version is adapted for low-temperature applications: for instance, coupling the panels to geothermal probes with a water-water heat pump (a system with an operational temperature of about 20°C) and pool heating (with an operating temperature of about 25-30°C).
Non insulated SPRING4
The insulated version of our panels is adapted for domestic hot water (DHW) with an operating temperature of about 50-60°C.
The finned version is designed for coupling with water to water heat pump and enable a better exchange with the ambient air.
