Business Challenge

Dakota Refrigeration’s large service area can result in lengthy travel time to the job-site. Mike’s team was challenged with a refrigeration equipment install 200 miles from the shop. This means incurring additional costs for weekly drive time, employee lodging, and daily allowances. The refrigeration system for the 25,000-square-foot store was designed for use with R-449A. It included numerous medium and low temperature glass door merchandisers, one open meat case (6-inch length) and four island freezers/dual temperature cases.

Solution Overview

Dakota Refrigeration wanted to increase their bottom line. To do that they needed to find a way to decrease labor costs, which led them to ZoomLock. HVACR contractors have had to rely on brazing as the way to join copper tubing and fittings for refrigerant lines, and, brazing requires highly trained, highly paid technicians, fire permits, fire spotters, brazing tools and gases, nitrogen purging, and more. With a reported 40-60 percent reduction in time and labor costs on tubing connections, using ZoomLock made sense. By installing ZoomLock, Dakota Refrigeration was able to save two weeks in labor costs.
