Small details.
Purposeful engineering.
Meet the latest iCO concealed nozzles and the pump unit behind the system. The right combination starts with the right specification.

Concealed high-pressure
nozzle MK2.
A discreet concealed pendant nozzle for residential applications, with published fire-test evidence to BS EN 14972-17.
- Product code
- iCO-HP-09
- Ceiling finish
- Cover approximately 6 mm below ceiling
- Minimum ceiling void
- 130 mm
- Published test scope
- Tests A–E at 2.5 m; test A at 3.5 m
Information from iCO’s 22 April 2026 datasheet. Occupancy, ceiling height, hydraulic design and installation conditions apply. Product render shows the assembly and protective cap.

Concealed low-pressure
nozzle MK1.
A concealed low-pressure option with its own design requirements and residential fire-test evidence. Suitability is assessed for the complete system.
- Product code
- iCO-LP-01
- Minimum operating pressure
- 6 bar
- Minimum ceiling void
- 110 mm
- Published test scope
- Tests A–E at 2.5 m and 3.5 m
Information from iCO’s 22 April 2026 datasheet. Water supply, operating nozzles and installation limits must be checked for the project. The coloured cap is a protective product component.

Compact pumping.
Integrated monitoring.
The pump forms part of the overall high-pressure system. Its position, supply, access and configuration are coordinated during project design.
- Product shown
- iCO pump unit
- Key considerations
- Water supply, configuration and access
- Project coordination
- Location, power and pipework
- Ongoing care
- Manufacturer servicing requirements
The pump must be specified as part of a compatible system. Performance and standards evidence relate to the selected system configuration, not the enclosure on its own.
The building comes first.
Nozzle choice is only one part of the design. Occupancy, ceiling geometry, protected areas, water supply, required nozzle operation and manufacturer limits all affect the proposed system.
We review those requirements with your project team and coordinate the design information needed for the installation.
Two nozzle options.
Different design requirements.
