Thanner Serviceable Hydrostatic Release Units are
designed for heavy duty installations, reliable
function and no limited lifetime if serviced
regularly. Service intervals follow the raft
servicing. The units can be manual released and reset
for continued service.
The units are all approved to the new MED and SOLAS
regulations together with ships wheel approval, USCG,
TC and many others.
The units are made from stainless steel and composite
polyamid plastic to meet the tough requirements of the
marine environment.
The units operate independently of the life raft
buoyancy and are approved for any life raft up to a
load of 1850 kgs.
All parts can be recycled and are made from non-toxic
materials.
Special versions/release depths are available on
request.

Thanner Disposable Hydrostatic Release Units for
Remote Activation are based on the standard disposable
HRU range. The standard units are fitted with adaptors
enabling remote activation by means of mechanical,
electric and pressure means.
One unit alone can act as hydrostatic release and
remote release unit, which simplifies the installation
and increase safe operation.
The units have the same approvals as the standard
units.
Electric Activation:
The HRU has a pyrotechnic activator, which by limited
electric power activates the HRU for release. The
power can be supplied either by batteries or the ships
emergency supply system, or both as safety back up.
The electrice installation is a standard ships
installation like a fire alarm system. The activation
can be done by means of a control box situated in the
wheel house. Two wires are necessary for each HRU. No
limits of distance from the control box to HRU's.
Programmed priority of release sequence. Close
proximity activation at life raft cradle.
Mechanical Activation:
The HRU has an adapter to which a mechanical
connection can be fitted. The mechanical activation
could be by means of a TELEFLEX or MORSE cable or by
means of any kind of mechanical connections. This
method can be used for limited distances only.
Pressure Activation:
The HRU has an adapter to which a pressure line can be
connected. The pressure can be supplied from a gas
cylinder or a pressure tank. More units can be
activated simultaneously or one unit at a time if fed
by individual pressure lines. No limit in distance
from control panel to HRU.
