TacoSol Load Mega (L)

Connection-ready storage loading station with high-efficiency pumps for efficient thermal transfer of solar energy to one or two storage tanks

Description

The TacoSol Load Mega L storage loading station performs the zone-based loading of one storage tank or loading of two storage tanks via a thermal solar installation according to the available flow temperature.

Advantages

  • Maximum solar yield from the roof to the storage tanks owing to high-quality stainless steel plate heat exchanger
  • Zone-based loading of one storage tank or loading of two storage tanks
  • Speed control of the primary and also secondary pump for optimal temperature differentiation
  • Stable stratified loading in the storage tank
  • TacoControl Tronic for recording the primary return temperature and the primary flow rate
  • Maximum energy efficiency, for example for generating fresh hot water with the TacoTherm Fresh fresh water stations

Functions

  • The TacoSol Load Mega L is a compact loading station equipped with EPP design insulation for loading one or two storage tanks by means of a solar system.
  • The solar energy recovered is transferred via a high-efficiency stainless steel plate heat exchanger to the storage tank(s). By controlling the speed of the primary and also the secondary pump, the integrated controller ensures the optimal conditions are in place for achieving the best possible solar yield.
  • The parameters required for this purpose for the TacoSol Load Mega L with switching valve are determined, for example, by means of TacoControl Tronic. The controller regulates the three-way switching valve to operate either storage inflow 1 or 2. This ensure optimal loading of one or more storage tanks.
