"Lawler's has a unique application [in that it] requires a lot of capacity in a very small footprint, which gave the competition an advantage in the past," Goggins says "But the VSM new Cool Compression had all the features required for this expansion."
The compressors and spiral freezers work together to chill their product down to ,40 degrees F just before the desserts are sliced and packaged. The colossal New York Cheesecakes, Chocolate Eruption, Tiramisu and Bananas Foster are then shipped to restaurants and retail outlets in the U.S., Puerto Rico, Europe, Canada and Mexico, all under the Lawler's brand name.
The VSM Cool Compression is part of the Vilter line of Single Screw Compressors. The slides allow operation at extremely low ratios, which permits the compressors to operate more efficiently and reliably with higher suction pressures and lower ratios than other screw compressor types.
Since the dual slides operate in parallel rather than in series, the Single Screw Compressor can operate with optimum efficiency even at part-load conditions. By comparison, when screw compressor have dual slides that operate in series, one of the slides is apt to block off some of the porting behind the other slide, creating a restriction and performance penalty at part-load conditions.
Lawler's products are distributed to national restaurant chains, wholesale clubs and retail outlets.
