Conveni-pack can be provided with a freezer booster pack for use with low temperature refrigeration. This option brings additional energy savings and simplifies installation by limiting the length of heavily insulated pipe required. 
The freezer booster pack contains a satellite compressor which provides the first compression stage from -35° into the suction line of the high temperature refrigeration. The second stage compression is performed in the outdoor unit. This allows significantly lower compression ratios, reduced energy consumption and end temperatures. The length of heavily insulated piping can be limited by placing the booster unit within 10m of the low temperature cabinet or unit coolers, reducing the material and installation costs compared to conventional systems. The freezer booster pack should be installed indoors.
