Hydrogen Leak Detector for Plate Heat Exchangers0 pages

HLD Series
UNIQUE AND RELIABLE
The hydrogen leak detector of
the HLD series is the perfect
instrument for industrial leak
detection.
It is small, robust, and extremely
sensitive to hydrogen
gas. It can be used to detect
leaks up to 5x10-7 mbarl/s. As
it is insensitive to other gases,
testing results are 100% reliable.
OPTIMAL TRACER GAS
Hydrogen being the least expensive
tracer gas available,
we use a tracer gas mix which
contains 5-10% H2. Due to its
low viscosity and its small
mass, hydrogen spreads extremely
fast in the plate heat
exchanger, thus reliably detecting
even the smallest leak
in a minimum of time.
