Filtaire
In areas where LPG quality is poor it may be necessary to install
FILTAIRE or FILT-EZE Gas trap at the outlet of your vaporizer.
♦ For model Z150 use FILTAIRE model F4 P/N 20536-ASME.
♦ For model Z100 above 14ºF (-10ºC) ambient temperature (35
psig (2.4 bar) saturation pressure) use FILT-EZE P/N 82288.
Below 14ºF (-10ºC), use FILTAIRE model F4 P/N 20536-ASME.
♦ For models Z25, Z40 and Z50 use FILT-EZE P/N 82288.
Installing Multiple Vaporizers
Multiple ZIMMER vaporizers can be manifolded together to
increase the total system capacity.
♦ Manifold the inlets and outlets together using similar length
piping runs. It is best to keep the piping as short as possible.
♦ Install an isolation valve at the inlet and outlet of each vaporizer.
♦ Install an appropriately sized regulator with Fluorocarbon
elastomer (Viton) seat after the outlets have been manifolded
together. For more than two vaporizers use one adequately
sized regulator with a Fluorocarbon elastomer (Viton) seat.
Common piping problems
Problem: Frost or condensation on the liquid LPG piping.
Cause: Vaporizer installed with undersized piping from
storage container to vaporizer.
Reason: Liquid LPG boils in the pipe before the vaporizer
causing a reduction in vaporization capacity.
Problem: Moisture or water droplets on the piping before the
regulator. Frosting of the regulator.
Cause: Outlet regulator installed too far from vaporizer or
below vaporizer outlet.
Reason: High pressure LPG vapor condenses between the
vaporizer outlet and the regulator.
Problem: Downstream component failure.
Cause: Drip leg or filter is not installed or is too small.
Reason: Oils or heavy ends collect in downstream regulators
and other components.
