Led Freezer and Refrigerator Lighting

Posted on March 27, 2014

It's amazing what lighting can do! Have you ever been inside of your walk-in cooler or freezer and that dim, dull light just makes you want to get out ASAP? Sure it's freezing in there, but think about it; lighting can make you feel dreary, down and outright crabby. Your employees that inventory items in your walk-in feel the same way. They just want to get out of there. Ever wonder if they got the right counts on the cases of beer, the boxes of shreaded cheese or the crates of milk? Whatever your product, it's your lifeblood. You can't afford for it to be miscounted, mistreated, or missing. Ever wonder if you actually got the product from your vendor or if you gave away profits? LIGHTING IS A BIG DEAL. It's also a hassle to be constantly changing light bulbs due to the extreme temperatures. Keep your employees happy and off the ladder. Our new LED Lighting will last 50,000 + hours! Check it out today.

How Smart Refrigeration System Controls Save You Money

Posted on March 27, 2014

Look, Crosstown is not just another mechanical refrigeration contractor operated by a conglomerate or Board of Directors. We, the owners, Pat and Dave, came from the service and install field. We're technicians, not salesman, and we see a lot of new products for refrigeration systems that claim to save energy. We can debunk most of these claims, but there is one product that actually will save you energy and money. Here's how.

 

We're going to get a little technical here. With freezers, and most refrigerators, you have a defrost cycle. This defrost cycle uses electric heaters on the back of the evaporator coil and inside the drain pan to melt the ice and/or frost from the coil. This is traditionally done with a timeclock and this clock is set to defrost your coils on the most humid of days. You know as well as we do that here in Minnesota it's only humid three to five weeks a year. Most businesses dont want problems with a coil frosting up and causing product loss so their timeclocks are set to defrost for the worst conditions.

 

The control on this product, however, is smart. It senses coil temperature, chamber temperature, superheat and also looks at runtime. It is a refrigeration system controller and can be used with an electronic expansion valve to fine tune not only the defrost but also the temperature precisely down to a tenth of a degree. We have tested this control and are very excited to announce that we took multiple Dairy Queen freezers running defrosts four times a day down to four times a week! Just imagine how much money you can save if your defrost was pulling 40 amps for 45 minutes four times a day and now it's 40 amps for 18 to 35 minutes four times a week through a pulse-enabled, managed controller! This control also is web-enabled allowing you to recieve email alerts on system problems well before you lose valuable product! You can even connect multiple units together for redundancy.

 

The sky is the limit with this new control technology. Not only that, but these units are also affordable! Call us today for more details so you can start saving money tomorrow. We guarantee it!
