ThermaFlow Plate Heat Exchanger Packages
Primary Heat Source
- Low Temperature Hot Water (LTHW): Typically 82°C flow / 71°C return. A common source of primary heat.
- Medium Temperature Hot Water (MTHW): Max. flow temperature 120°C, max. working pressure 3.4 BarG.
- High Temperature Hot Water (HTHW): Flow temperature above 120°C, max. working pressure 10.3 BarG.
- Thermal Oils: These allow high temperatures at low pressure. Primary connections should be flanged and have oil-resistant gaskets. Copper degrades some oils so the tube bundle may have cupro-nickel or stainless steel tubes.
- Refrigerant: Superheated refrigerant can be cooled (and condensed if required) to heat a calorifier between compressor and condenser. A back-up system should be provided for times when the calorifier is unavailable.
- Waste Heat: If waste heat is only available at low temperatures a separate top-up heat supply will be required. We can advise on the best match of calorifier to waste heat availability and hot water demand.
