1 Introduction This document describes cooling insulation for gasketed plate heat exchangers. Cooling insulation design comes in two sizes: medium and large. In the table below, GPHE models are specified in order. Insulation size Product name (AQ-model) (AQ2T) Medium (AQ2L) (AQ2T) (AQ4L) TL10...
2 Description The insulation panels are designed to ensure simple assembly and disassembly. They are equipped with connecting latches for the medium and large sizes and screws for the small size. The insulation also includes a drip tray with a drainage to collect condensation from the heat exchanger.
3 Limitations The cooling insulation has the following limitations: • The insulation can only be used for a certain temperature range. For more information, see the section Technical data. • Insulation may not be available for all plate heat exchanger models with holed pressure plate.

The data listed in the table below are for a standard plate heat exchanger with a standard carrying bar, hole only in the frame plate and standard connections. For non-standard plate heat exchangers, contact your Alfa Laval representative. Insulation panels...
7 Installation 7.1 Insulation for medium units This section is only valid for insulation intended for medium units. See Chapter Introduction for sizing. On the rear insulation panel of medium sized insulations, cut out holes for tightening bolts and carrying bar. On the rear insulation panel of medium/large sized insulations, cut out holes for tightening bolts and carrying bar.
