REFRIGERATION SYSTEM DESIGN SERVICES

A common practice today is for customers to take advantage of the "free" design services that are offered by their primary equipment vendor. You have heard the adage, "You get what you pay for." Based on our review of hundreds of refrigeration/HVAC system designs, we believe this is true.

An equipment vendor's first job is to maximize the placement of their technology. Who ensures that your entire system is optimized? Who addresses the system integration requirements for optimized and efficient refrigeration and HVAC?

We know from experience that if your system isn't designed correctly from the beginning, it will not perform to your expectations. Identifying problems in the Design Phase is much less expensive than re-working the problem after the store is operational. The value of a solid and sustainable design far outweighs the initial cost.

At Cold Tech Refrigeration, we are technology neutral. We have experience designing, installing and servicing virtually all manufacturers' products. This experience has taught us what works and what doesn't.

Our goal is to optimize and sustain refrigeration systems, so we focus our designs to deliver these results. We take a "systems" view and focus on optimizing all of the components of your refrigeration and HVAC systems. We don't simply copy and paste your prototype design; we evaluate each project individually and provide complete coordination through the project to insure that your best interests are carried through.

You are investing a lot of money in your new or remodeled refrigeration or HVAC system; and it is critical to your business. Doesn't it make sense to have our engineering experts provide an objective review?

 

REFRIGERANT CONVERSIONS

The movement to convert HCFC refrigerants to HFC refrigerants started back in 1989 when the Montreal Protocol on Substances that Deplete the Ozone Layer first went into effect to ultimately eliminate the production and use of CFCs and HCFCs, worldwide. The protocol requires elimination of the production and use of HCFCs by 2020. In the U.S., the Environmental Protection Agency (EPA) established specific regulations to implement the Montreal Protocol, which incorporates a "stair step" approach to eliminating HCFC production and use. The EPA has issued several more aggressive amendments to their original regulations, driven in large part by the global warming effect of HCFCs.

The most recent EPA amendment issued in January 2012, resulted in R-22 refrigerant costs doubling almost overnight! With significantly higher costs, R-22 supply shortages eminent and 2020 right around the corner, the time to plan and execute your refrigerant conversions is now! Source is ready to work with you to develop turnkey short-term and long-term plans to convert your systems to acceptable HFCs that meet your corporate and performance objectives!

 

DOOR RETROFITS

Refrigeration makes up more than half of the energy used in a grocery store, and open multi-deck fixtures account for a large portion of the total. Door retrofits give you the opportunity to significantly lower your operating costs. In fact, it is possible to reduce energy use well over 50 percent on open, multi-deck cases!

The Cold Tech Door Retrofit Program involves enclosing your multi-deck cases with retrofit glass doors and, when required, replacing older doors with current technology doors. As a full-service refrigeration & HVAC company focused on providing solutions that help your bottom-line, we perform our complete turnkey Door Retrofit Program on virtually any major case manufactures' equipment and using most major door manufacturers' products.

In addition to significant energy savings, there are many benefits of a door retrofit program, including:

Product integrity - with doors in place, merchandise is no longer subjected to the drastic temperature variations of open fixtures and has been proven to last longer. Customer perception of product integrity of products behind a glass door is higher, and they help ensure that the FDA's mandated 41°F is consistently maintained.

Improved Shopper Experience - the aisles in your store are warmer and much more comfortable; customers dwell longer in front of the merchandisers and purchase more of your products!

Products are "showcased" - LED lighting (available on most new doors) presents the product in an enhanced, brighter, cleaner and more visible way; improved sales follow.

Avoided maintenance expense - LED lighting lasts 5 times longer and is up to 50% more energy efficient than traditional fluorescent tubes.

Utilities are on board - many utility companies recognize these retrofits as "prescriptive" measures; in other words, you do the work, they give you a rebate. Cost to install doors can be significantly offset by utility incentives, improving your ROI.

Equipment capacity for future use - case BTU loads are reduced up to 70%, thus freeing up refrigeration system capacity for future expansion, or to help marginal systems get by today.

Perception of a store remodel - many shoppers comment that the new doors create the impression that the store has been remodeled. This positive perception is good for sales!

The comprehensive Cold Tech Refrigeration Door Retrofit Program includes the following steps:

Store survey

Determine exact case sizes, models, age, etc.
Provide photo documentation of all affected cases.
Identify and report any other problems that need to be addressed during the retrofit.
Document pertinent information relating to the existing compressor systems that will be affected by the modifications.

Engineering

Analyze the existing compressor system with reduced loads; recommend modifications; define the project scope of work.

Provide refrigeration floor plan with modifications, component changes, piping changes etc.

Recommend additional modifications that benefit energy improvement, maintenance cost avoidance and system control capability.

Installation

Dedicated crews versed in all necessary aspects of the project execute the door retrofit installation with a well planned approach that is coordinated with store operations.

Installation includes the disposal of existing lighting, modification of piping, valves and components, electrical for new doors, and machine room modifications related to load reduction.

Optimization

Adjustment and fine tuning of the system after door installation and required modifications.

Provide QA reporting, documenting the state of the system once complete.

Utility coordination with respect to ensuring the system is operating as required for utility incentives.

The Cold Tech Refrigeration team has the training, experience, dedication and resources to ensure your organization receives the most technically advanced services available and realizes the greatest cost savings.

ENERGY MODELING

Cold Tech Refrigeration can provide energy modeling services to compare or predict energy usage for your supermarket refrigeration systems. Our Energy Modeling service is often useful as part of an optimization or remodel strategy, or reviewing current versus newer technology. Source is also able to address reductions in consumption for utility incentive programs.

 

STORE SURVEYS

Your remodeled store or refrigeration system is too big of an investment to leave anything to chance. You need to know your true starting point before you can properly plan, design and estimate the true cost of your remodel. Often times with years of changes, re-sets, equipment replacements, etc, it is almost impossible to have an accurate and complete picture of what needs to be changed out as part of your upcoming remodel.

Let our technical experts provide a pre-remodel store survey so that you know exactly what you have, and what needs to be replaced prior to designing your remodel project.

With a Cold Tech Refrigeration Survey you get:

  • A complete list of current refrigeration equipment
  • A "working condition" assessment on all current equipment and major components
  • Recommendations on equipment or component change-outs or upgrades during the remodel to ensure maximum system performance and energy efficiency after the remodel
  • Peace of mind knowing that the "starting point" for your remodel design is current, accurate and complete

Let Cold Tech Refrigeration's  team of engineering experts perform your Store Survey to start your remodel project out right!

 

ENERGY COMPLIANCE

 Cold Tech Refrigeration can supply State, Local or Federal energy compliance calculations, such as Title 24 or local energy codes. Included is the complete compliance engineering for each applicable code or compliance requirement; stamped by a professional engineer, and current to match the local criteria specified.

 

ENERGY DESIGN REVIEW

Cold Tech Refrigeration can provide engineered services that focus on providing a review of your existing systems to insure that you have the most energy efficient operating system possible. This analysis service can apply to new installations (at the design or construction phase), remodels, or simply operating systems that appear to use more energy than predicted. The deliverable would be a professional review of your refrigeration/HVAC/EMS equipment and processes, and providing a blueprint to energy improvement.

 

NATURAL REFRIGERANTS

The refrigeration and HVAC world is changing. As the more "traditional" HCFC refrigerants continue to be aggressively phased out by EPA regulations and by a focus on reduced carbon footprints and a "greener" society, refrigeration & HVAC users have been forced to search for adequate replacements for their systems. One trend that is quickly growing in the United States is the use of natural refrigerants like CO2, propane, and ammonia. While these refrigerants have been used in industrial applications for years, and are prevalent throughout Europe and other countries, they are new to commercial applications in America.

In anticipation of this growing need and demand for natural refrigerants, Cold Tech Refrigeration has proactively been involved in several high-profile natural refrigerant designs and installations with several of the world's leading grocers.

Let our experienced team of engineers help you determine the best natural refrigerant options for your specific site and then work with you to design a system that provides the performance you need and the reduced carbon footprint that we all need! And of course, as with all of our work, each natural refrigerant system is designed to minimize your Total Cost of Ownership while providing optimal performance.

 

LED LIGHTING

Lighting in grocery stores represents about 13% of the electricity consumption, not including the impact on cooling loads. Lighting retrofits to LED lights can save 30 to 60 percent on lighting energy as well as 10 to 20 percent of cooling energy when compared to traditional, fluorescent lighting.

In addition to energy savings, today's LED lighting plays an important role in creating an inviting shopping experience and increasing sales through better product illumination. Advances in LED lighting technology now offer grocery stores an option to fluorescent lighting that produces better lighting, especially in refrigerated display cases because LED lights perform very well in cold temperatures. In fact, research has shown that customers find LED lighting in freezers to be "brighter, more even, more appealing and more comfortable." Packaging and food colors are brighter and more attractive to shippers. Additionally, LED Tube lights will only need to be replaced once every 10 years reducing maintenance and recycling costs.

Whether part of a new design, a remodel or a Door Retrofit program, the Cold Tech Refrigeration engineering team has the experience to assist you in the selection and design of LED lighting that is best for your system.
