Crosstown is now an XLT Oven Representative!!

Posted on April 11, 2014

We just completed our latest installation of a triple stack of XLT pizza ovens in Green Mill's mobile pizza trailer. The installation consisted of removal of some older models and fabrication of a new stand and rework of the LP gas and electrical circuits. Mike, the trailer manager, just stopped in with some ingredients and we cooked two pizzas. They came out perfect the first run through and were the best pizza I have had! These new XLT ovens will cook a pizza in 6 minutes! Unbelievable!

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!

Cold/Warm Stability Chambers Installed for R&D Lab Scientific Refrigeration

Posted on March 27, 2014

When Protatek Labs in St. Paul was searching for a stability chamber they knew to turn to Crosstown Mechanical. We have provided and installed turnkey cold/warm stability chambers since 1979 for many University of Minnesota projects as well as private R&D lab installs throughout the Twin Cities and beyond.

Engineered Direct Fire Burn Package for Distillery

Posted on June 20, 2013

When Bartley Blume decided to "shed the shackles of corporate bondage" and take home brewing to the next level, he called us. It's a story of a home brewer going big, but not with beer. He decided to distill alcohol and open the first brewstillery in the Twin Cities called Bent Brewstillery http://www.bentbrewstillery.com.  We are engineering a direct fire burner package to be installed under this 500 gallon still in which he will use in his process. The challenge is to "make something rather than buy something" as Bartley puts it. Bartley believes that direct fire carmelizes the sugars in a different manner than steam-jacketed stills do and therefore will produce better flavors. Stay tuned for more on this project as it progresses! Contact us with your plans to bring home brewing to the microbrewery level. We have assisted many microbreweries in the Twin Cities with everything from process piping, brewhouse installations, and chiller systems for the fermentation process to walk-in refrigerators for the final product!

Engineered Process Dehumidification System

Posted on June 20, 2013

This customer contacted us with a problem. Their process involving beef jerky and beef sticks had a flaw that was found due to excess humidity in their product. We engineered a dehumidification system to remove humidity from the product and resolve their quality issues. We used a 20 horsepower commercial refrigeration system and outfitted it with hot gas capacity controls to keep the system online throughout the process. A dehumidification coil was installed to remove humidity from the airstream in a specialized chamber called a fermentation room. The system now keeps humidity within 3% of setpoint. This resolved all quality issues so that the customer has a product that not only tastes great but has a texture second-to-none!

-20C Redundant System Walk-In Freezer Chamber

Posted on April 23, 2013

One of our valued customers specified the need for a backup refrigeration system due to the temperature-sensitivity of their stored product.  Alerton DDC Integrated Controls cycles each of their refrigeration systems every 24 hours. It the event of a mechanical failure of the refrigeration system, the backup system starts and now notifies engineering of the issue. Now they can move to immediate remediation and ensure their product is kept at necessary temperatures to prevent loss or damage of valuable inventory.
