Collector Assembly
Connection Information
The Navitas panel has been designed to make connection between panels and to flow
and return pipe work simple and with as little number of joints as possible.
Connecting Panels Together
The Navitas collector has a ¾” flat face male thread on one side and a swivel nut ¾”
female on the other side. This means that each panel connects directly to the panel
beside it. A fibre washer must be inserted between the flat face of the male thread and
the internal of the female swivel nut.
Connecting Flow & Return Pipework:
Tails – 075m Stainless Steel
Each tail has been manufactured with a swivel nut on each end. This swivel nut screws
directly onto one side of the panel system where the ¾” flat faced male thread con-
nection is. A ¾” x ¾” flat face nipple must be used between the swivel nut on the col-
lector and the swivel nut on the tails.
Stainless Steel Solar Pipe
When using solar pipe as flow and return pipe work then it is advisable that 0.75m
long tails are not used also as this increases the number of joints in the system. The
solar pipe should be pre butted using the single fitting and nipple and then the fiber
washer inserted in-between the joint to finish the seal. . The swivel nut fitting on the
solar pipe will screw directly onto on side of the collector system where the ¾” flat
faced male thread connection is. A ¾” x ¾” flat face nipple must be used between the
swivel nut on the collector and the swivel nut on the solar pipe.
Insulation
All pipe work on the solar loop should be insulated with high temperature insulation
(such as HT/Armaflex from Armacell GmbH). High temperature insulation is essential
as regular pipe insulation will melt at temperatures experienced by solar pipes. The
wall thickness of the insulation should be equal to the diameter of the pipe. The only
pipes which should not be insulated are the pipes to the safety vessels as they should
allow heat to dissipate when the system is experiencing excessive heat and pressure.
