Heat treatment is essential to cure the adhesive and
obtain maximum bond strength. This is done using
steam or hot water to heat the plate pack. Attach a
low pressure desuperheated steam line to an upper
port and slowly raise the temperature of the plate pack
to at least 220
º
F (105
º
C). Maintain the temperature
for a minimum of three hours.
If steam is not available, hot water may be used with
the same temperature and time requirements as
steam.
After the required time, allow the heat exchanger to
cool naturally to room temperature and complete the
tightening to the required dimension per paragraph
5.6.
Attachment of Paraclip Gaskets
Non-glued Paraclip gaskets are an alternative to glued
in gaskets that greatly simplifies on site regasketing.
The gaskets have a series of small nubs or projections
molded into the underside of the gasket. These
projections fit into corresponding slots located around
the periphery of the plate and port areas, securing the
gasket to the plate
(Figure 26) . When the plate heat
exchanger is tightened, a complete and secure seal is
assured.
To attach an Paraclip gasket, the gasket is laid out on
the plate in its correct position. The projections are
firmly pressed into the corresponding slots in the
plates. After installing the gasket, the plate may be
immediately installed in the frame in preparation for
tightening.
