Sprinkler designed for fire ember protection

The Platypus Sprinkler can be installed during construction of new homes and buildings so that the pipework can be concealed or in the case of existing dwellings and buildings, they can be easily and cost effectively retrofitted with exposed pipework.

The Platypus Sprinkler has a twin outlet head that spins on a central shaft. The design of the head ensures water droplets spray out and down from the sprinkler head and water is sprayed in a full circle pattern.
A unique feature of the Platypus Sprinkler is it doesn’t have an outer support frame around the spinner.

This ensures the water stream is not broken and therefore the concentration of large droplets dispersed is higher and less wind affected - this means more water stays on the building. Other sprinklers that have an outer support frame produce smaller droplets and mist - making them less effective.

Note: We recommend using our flow control inserts at each sprinkler to ensure optimum performance (see over for more information).

Sprinkler operating parameters

This illustration (below) shows the recommended sprinkler installation range.

An operating pressure of 45 psi to 50 psi at the sprinkler head is ideal.

Note - Due to manufacturing processes you may see some sprinklers start to run earlier than others. There may also be minor differences in the running speed of the sprinkler head, this does not indicate a faulty product.
