Titanium Plate Heat Exchangers

Q: What kW rating do these come in?

There is no fixed rating — each unit is built to your duty, so the kW depends on the flow rate and inlet temperature on both sides.

Q: Which plate material do I need?

Titanium for seawater and aggressive water, AISI 304 or 316 for fresh water, with SMO and Hastelloy available for harder duties.

Q: Why use a heat exchanger instead of heating the water directly?

It keeps culture water separate from the heating or cooling circuit, so you can run off a boiler, bore water or a glycol chiller without exposing stock to it.

Q: What pressure and temperature can they handle?

Up to 35 bar working pressure, and working temperatures from −20 °C to 180 °C.

Q: How large can they go?

Connections run DN25 to DN600, plate lengths up to 5.5 m, and flow rates up to 7,200 m³/h.

Q: Are they serviceable?

Yes — the gasketed plate pack comes apart for cleaning and plate replacement.

Q: How do I get a price?

Send us the heat load in kW (or your water volume and target temperature), the flow rate and inlet temperature on each side, and your water type — we will select a unit and quote it.

Gasketed plate heat exchangers built to order for heating or cooling aquaculture and seawater systems.

Key Features

Danfoss gasketed plate heat exchangers, built to order against a duty rather than sold as fixed models
Plate materials to suit the water: AISI 304/316 stainless, titanium for seawater and aggressive water, with SMO and Hastelloy available
Gaskets in EPDM-HT, NBR-HT or Viton
Connections DN25 to DN600 (1″ to 24″), plate lengths up to 5.5 m, flows up to 7,200 m³/h
Working pressure up to 35 bar (500 psi); working temperature −20 °C to 180 °C
Frames designed to FEA and PED 2014/68/EU (EN13445) or ASME Section VIII Div. 1
Keeps culture water separated from the heating or cooling circuit — the way to run off a boiler, bore water or a glycol chiller without exposing stock to it
No fixed kW rating is published, because duty depends on the flow rate and inlet temperature on each side. To size one, give Fresh By Design the heat load in kW (or the water volume and temperature lift you need), the flow rate and inlet temperature on both the primary and secondary side, and the water type — we select the plate count, plate material and frame for that duty.
