Spirec heat exchangers are spirally wound and welded plate heat exchangers without any gaskets (Spirec patent). The internal circuit is a single channel, which ensures excellent flow and speed control. This original design of the exchanger provides unique advantages: exchange efficiency, very high difficulty to scale. Depending on the desired power, several exchangers can be mounted in parallel on collectors to cover the needs. Depending on the application, Spirec heat exchangers are made of stainless steel 316L or Titanium.
The water exchangers are cylindrical in shape. The spirally wound plates are fully welded. They are used for domestic hot water production, energy recovery, and for DHW preheating. These exchangers are ACS.
